Web components have been around for a long time (since HTML 5 became a thing), but there hasn’t been a lot of attention given to them until recently. Now, tech organizations around the world are adopting them and finding tremendous efficiency in creating framework-agnostic reusable components to build their UIs.

In this talk, we will cover what web components are, how to get started with building with them, and some of the efficiencies they bring to organizations.

About Burton

I am a software engineer at Microsoft, working on one of their design systems.

I am also the creator of various open source projects including Kickstand UI (a design system built with web components - kickstand-ui.com) and Clarion (a style framework for managing design systems - projectclarion.com).

In my free time, I love spending time with my wife and three daughters, practicing martial arts, jamming on my ukulele, and learning new things (usually about software engineering).

Svelte is a compiler and component framework for building web components and web applications. It is often compared to React and Vue and fulfills many similar use cases. However, there are major differences in capabilities and framework architecture. It has some of the highest satisfaction in developer surveys, beating React, Vue, and Angular. And it beats all those frameworks on performance benchmarks too.

We will briefly talk about the benefits to users and developers of building with Svelte before diving into details. We will cover setting up a project, the special Svelte syntax, building basic components, managing the state across an app, advanced animation, and more. Hopefully, by the time you leave, you will be able to build your own highly dynamic apps using Svelte.

Join us for a brief overview of the why and how of running your server side JavaScript in a serverless environment! We’ll talk about AWS Fargate and AWS Lambda. And of course there will be demos!

Aircraft are everywhere. Knowing exactly where is paramount as it’s considered bad form for two aircraft to be in the same place at the same time. To avoid this, aircraft worldwide constantly and publicly broadcast their location, heading, and all sorts of other data using a system called ADS-B or Automatic Dependent Surveillance Broadcast.

This data is a natural fit for a streaming architecture. After all, it’s a constant stream of data that is literally being broadcast in real-time. But how can we capture these broadcasts and the data within? Surely it must require expensive hardware and special tools!

Not so much. It turns out that we can capture ADS-B data easily using a combination of a cheap radio dongle and free software—a combination called software-defined radio. From there we can store it in a streaming data structure and consume, transform, and publish it using microservices. Cool, right?

In this session, you’ll learn how software-defined radio works (and not just for ADB-S), how to receive and store ADS-B data in streams, and how to use those streams with microservices. And, I’ll do it all by example—building a dashboard showing real-time flight data using Node.js, Redis Streams, and whatever front-end JavaScript framework happens to be popular that day!

Micro services are ubiquitous. However, most companies that implement micro services do not reap their full benefits - at best. At worst, it’s an epic failure.

There are reasons for micro services: independent deployment of business capabilities. However, the unspoken assumption is that you need to deploy all capabilities all the time. My experience has shown me that it’s plain wrong. Some capabilities need frequent deployment, while some are much more stable. In “the past”, we used Rule Engines to allow updating business rules without deployment. While it solved the problem, this approach had issues. Between introducing a Rule Engine and migrating your complete system to micro services, I believe that there’s a middle path, and that this path is Function-as-a-Service.

In this talk, I’ll detail every point I’ve made above, and show how one can use Serverless to pragmatically design a system that allows deploying as often as you need.

Nobody questions building backends with Node.js anymore. It has proven itself and is widely accepted as an excellent platform for web servers. But have you ever thought of building CLI tools with Node.js? It turns out that Node.js is also great at that. Using just a few simple built-in modules, you can create powerful tools that can be used in terminals in all operating systems. In this talk, you’’ will learn how to use those modules through practical code samples and demos.

Imagine, if you will, your Manager asks you to develop a new desktop application. You’re so used to web development that you don’t know how to get started. What should you do? Dig out your old VB 6 books or learn a new technology? Better yet, keep those web skills and use Electron. Electron is the cross-platform application shell GitHub built initially for the Atom editor. The focus of this talk will allow you to leave with the starting skills to set up your development environment, generate your starter project, and build some business logic. Chris Woodruff will be your guide to leveraging your valuable skills for the desktop.

From hands, to chisels, quills, the printing press, and now the web, a written record of our existence has been a constant throughout history. Languages, and how they are depicted, have evolved alongside the tools we use to render them. Often overlooked in design, text content is an integral part of the visual aspect of an application and CSS allows us to control and manipulate its look and feel.

In this talk we will cover a little bit about the history of typography leading up to where we are today, how to make decisions about fonts and their usage in our application, and the CSS properties that allow us to manipulate our type for a polished beautiful design.

This session will unpack how Amazon’s Alexa works, how you think about building voice user interfaces, and which best practices you should consider as you build skills. We will cover this using the Alexa Skills Kit SDK for Node.js and the ASK CLI.

Have you struggled to get TypeScript and Vue to play well together? Me too. Vue is a fantastic SPA framework, and TypeScript is a great way for catching errors faster. Together, they can boost your productivity. Join us as we peel back the layers of TypeScript and look at the tricks of the trade to get them playing well together. You’ll leave with a solid methodology and code samples to get started with Vue + TypeScript.

Jinkies! Spoiler Alert! If you’ve seen Scooby-Doo, you know who the monster always is—Old Man Withers, the guy who runs the amusement park. Amusement park operators like Old Man Withers have caused Mystery, Inc. all sorts of problems over the years. Problems that could be avoided with a properly trained recurrent neural network. With RNNs, Scoob and the Gang could have built a model to classify everyone’s speech. This would show them that Old Man Withers and the Redbeard’s Ghost sounded a lot alike!

We can help Mystery, Inc. with this problem by building a recurrent neural network to do just that. You know we got a mystery to solve, and we’re going to solve it by building our model using lines from Scooby-Doo, Keras, and TensorFlow. Once we have our model, we’ll host it on RedisAI so we can quickly build an application to make use of it. Well, we’ve got some work to do now.

I will also explain what neural networks are in general, what recurrent neural networks are in particular, and discuss some practical use of this technology. When we’re done, you’ll know how to build RNNs with Keras, use them to classify text, and integrate them into your application. But more importantly, you’re going to have yourself a Scooby snack! That’s a fact!

Web developers tend to be unabashed defenders of the web platform, and tend to view native mobile platforms as proprietary, gated and bloated.

As a long-time web developer I felt this way too, but then something unexpected happened: I joined the dark side, and spent five years of my career working on—gasp—iOS and Android applications.

Now, like an explorer returning from a multi-year safari—I have so much to share! In this talk I’ll discuss how native development has improved the way I write code for the web, and how you can incorporate the best native app performance and testing tips into your web workflows.

Have you ever asked a tester, “How in the world did you find that bug?” Or maybe you’re being asked to pick up testing activities on your agile cross-functional team—or just wondering what that strange language is the testers are speaking. Agile testing is its own unique skill set, and as quality has become a team responsibility, more and more the agile testing is being performed by non-testers. Increasingly, developers and others are being asked to test and shift left, but they are rarely given the tools to ensure their testing is up to snuff. This often results in wasted time and effort, not to mention costly bugs. Jenna Charlton will explore some of the basics of exploratory testing, testing terminology, and how you can start to think like a tester. Key takeaways include session-based testing with charters, testing vocabulary and techniques, the testing pyramid, understanding and communicating risk, and why automation isn’t always the answer.

Jenna Charlton has been a software tester for nearly a decade. In that time she’s focused on manual testing, taking a particular interest in web accessibility and usability. Jenna’s experience in testing runs the gamut from lone tester on a Scrum team to test lead on an enterprise-level project. Jenna’s primary areas of expertise are in agile testing methodologies, risk based testing, accessibility testing, and test leadership. She is a regular speaker at conferences, covering a variety of testing topics and team collaboration. Jenna is passionate about making testing concepts accessible and relevant.

When working on an enterprise application, the focus should be to make the application fast, which includes a lot of factors like lazy loading, bundle size of the application, and number of API calls. In this talk, we will learn how to optimize your application using the tools available.

He is also the author of the Ngx-Builders package and part of NestJsAddOns core Team. And he runs the Tech Talks with Santosh talk show, where he invites industry experts to discuss different technologies.

Do the letters N - G - R -X make you sad or happy? In this talk we’ll go over best practices you should be using when building enterprise angular applications with NgRx. These few tips will help you better organize and structure your applications and leverage NgRx to do all the heavy lifting in your apps. In the end I plan to turn your frown upside down.

Webpack is an excellent tool for bundling web applications for the browser. The advancements that bundling a web application unlocked propelled frontend applications to where they are today. If you’re building a production application with JavaScript, it’s very likely you’re using Webpack. But what if you could ship your applications without using a bundler? What if you could write applications with better performance and less developer overhead?

In this talk we’ll Explore Snowpack — an exciting tool that lets web developers “Bundle because you want to, not because you need to.” We’ll see how we can write applications using modern, ECMAScript Modules (ESM) natively in the web without a build step. From there, we’ll add more advanced tooling like TypeScript and light bundle step. At the end of this talk, you’ll be a bit more familiar with some of the native browser capabilities for modern JavaScript and some of the performance implications that bundlers can have on our apps.

Today’s fast-moving software delivery environment emphasizes pushing value to production as quickly as possible. “Value to production” implicitly requires high quality—low quality is of little value to anyone! —which means teams need to focus on being able to specify, build, test, and deploy software effectively and quickly. Acceptance testing historically been manually intensive efforts run by a dedicated QA department, resulting in a slower pace of production releases.

No longer do we have to make acceptance a manual effort that requires a dedicated QA department. With the release of Cypress, we have a new standard in front-end testing that allows every developer to create acceptance tests. Come learn how you can create fast, easy, and reliable test for anything that runs in a browser regardless of the front-end framework used.

You will walk away ready to end the era of “Developers don’t write acceptance tests” and start writing acceptance tests for all of your projects.

We live in a builder’s paradise, a world of 3d printers and massive batteries. One where amazing products such as Arduino and Raspberry PI provide amazing abilities. Now imagine doing all of this in Javascript! We will use Node to call native C modules that can communicate directly to GPIO pins. We will also look at how libraries such as node-serial can be used to easily communicate with Arduinos and other platforms. All of this will follow the pi-serial-example github project. So join us and learn how to embrace our robotic overlords.

Ever look at modern gaming and think “Gee, I really wish modern games looked like text-based games from the 80’s, but with a modern JavaScript front end”? If so, you have interesting hobbies.

There will be a little bit of something for everyone in this eclectic talk as Matt walks us through the basics of building a text-based game engine using TypeScript and NLP-Compromise.

We’ll walk through the process of prototyping the game world and its interface using event modeling, Balsamiq, and diagramming tools.

You’ll learn how to quickly take a mockup and build it out using Angular and Angular Material.

We’ll take an in-depth look at input parsing using NLP-Compromise to parse user commands and make sense of sentences without having to build a robust database of individual words.

We’ll see how Jest and test-driven-development pair well with Google Analytics to iteratively design and refine the way the game responds to player input.

We’ll close by talking about next steps and how this prototype could be fleshed out to a full JavaScript library and ported to other JavaScript frameworks.

Matt is committed to helping people (and their code) achieve greater things. After nearly two decades of working as a professional software engineer, Matt put away his mechanical keyboard and made teaching others his primary job in a continuing quest to invest in the community and up-and-coming developers.

Twitter has spoken and a solid hour or BeardCam it is. However, it was a trick! Whenever I’m on camera, it’s BeardCam!

The number two choice was to live-code on RedisMUD. So, that’s what we’ll be doing. I’ll be working with Node and RedisGraph. Tests will be written inusing Mocha, Chai, and Sinon.

The meeting will be streamed on Twitch and there’ll be a Zoom session going as well so y’all can interact with me while I code. Links to the Zoom will be on Meetup when you RSVP. So, please go and do that!

Like the rest of the world, we’re online only right now. As a result, the previously scheduled speaker is not able to make the meetup. I’m planning on filling in. We’ve got a couple choices here:

• I live-code RedisMUD using WebSockets, Node.js, and RedisGraph.
• I give a talk called “Understanding Probabilistic Data Structures with 112,092 UFO Sightings”.
• I brush and oil my beard for an hour.

Alternatively, if someone else would like to speak, I’d be happy to schedule you. Just drop me a line at guy at guy royse dot com (but, you know as an actual email address and not this bot shielding stuff).

Thanks, Guy

Want to create components that work regardless of the front-end framework you are using?

Tired of throwing away your components when you change front-end frameworks?

Wish you could just code it once and reuse it on all of your projects?

Me too! Components are a staple of front-end development as they increase development speed, consistency, and reduce the need for repeat code. To create components often we turn to frameworks such as Angular, React, and Vue but we don’t need to.

Using nothing more than HTML and Javascript that is readily available to us in all modern browsers we can create components that work without being tied to any one front-end framework.

You will walk away with the knowledge you need to go forth and create your own components, understand how to make them look gorgeous, and what if any limitations there are. Also, find out how you can bring back the blink tag!

NOTE: This month the meetup will be online only. We’ll be streaming on Twitch. Watch it at https://www.twitch.tv/ColumbusJS at 7:00 PM.

Tools, libraries, and frameworks that rely on modern JavaScript heavily make use of metaprogramming capabilities that is relatively new in the language. Much like Java, JavaScrip has a reflection API, but more important, it has the ability to both inject and synthesize methods and properties dynamically. In this presentation we will learn about the metaprogramming API, the benefits it provides, and how to do both method injection and method synthesis.

Vue.js, the new kid on the JavaScript framework block is taking the world by storm. Vue has bypassed React in their count of Github stars, alluding to how popular this framework is starting to become. Vue attempts to provide just enough support with libraries like Vuex and the Vue Router, and tooling like the Vue CLI to get developers productive, without aiming to be too opinionated, and too flexible.

If you are curious about Vue, this is the session for you. Come in for a thrilling ride as we explore this fascinating new library and mindset.

Last minute change! This month we’ll have Guy Royse showing everyone the ropes of WebAssembly and he’ll live code a kata of the audience’s choosing (within reason folks) in WebAssembly Text Format.

JavaScript is a language that was written in 10 days, but as it was adopted it evolved through organic community driven growth. This growth and the expansion of JavaScript outside of the browser, saw a need for additional features within the language. One of the most important and controversial of these was the introduction of modules and module loading. Modules increase the ability to abstract JavaScript code, allowing the complexity to be reduced and increases reusability. However, riffs in the community and slow implementation have made modules confusing for most develops. In this presentation we will take a step back and look at the history of modules in JavaScript, the different frameworks that were used to implement them and finally the ECMA Standard adopted by the working group. Once we are done you will be an ECMAScript module master!

Functional programming is a powerful design pattern for software development and is gaining momentum in the JavaScript community. Whether you are completely new to functional programming or have read introductory material on the subject and have begun to use the basics, you will eventually find yourself asking, “What next?” This session will introduce function composition in JavaScript as a design pattern and as a problem solving tool. You will learn two of the most important tools for composition — curry and compose — discovering what they are and how they can be used to write modular functions. By slowly building on a single code example, this session will demonstrate the common thread of composition in functional programming, from piecing together simple functions to utilizing functors for even greater composability. If you want to dive deeper into functional programming, it’s time to embrace function composition!

Let’s take a look at how JavaScript manages asynchronous events and some of the ways our decisions may work for, or against us.

In this discussion we will examine the ways that JavaScript coordinates and manages events using several coding choices and we can determine which are the good, the bad, and … the ugly.

This talk is about the journey of a former incarcerated prisoner who went from Coding in the Clink to his transition on the outside, coding out the clink. What started as a program in 2009 at Marion Correctional Institute as the Agile Factory with a few old Pentium 3 machines peaked the interest of not just men inside, but also volunteers and community members beyond the scope and purpose for which the program was intended. This collaboration between prisoners and IT tech professionals led to our prison conference know as Coding in the Clink. With such programing like this who needs prisons, after part of your rehabilitation brings a skill set that’s very much in demand and could possibly make you a living! However the majority of prisons are still inadequate in programing and resources. And while the Agile Factory provided a valuable skill set that men could take to college or possibly use on the outside, nonetheless with exposure to software craftsmanship prisoners still face barriers to employment. This talk will present personal experience navigating this nontraditional route to a difficult modern industry.

Starting a side project is easy, finishing it is hard but promoting it successfully is even harder. In this talk I would like to share what tools and technologies I use to make side projects & successfully promote them. This talk will go into detail on what you need to do to successfully share your work to the whole world instead of just your friends and families.

Software development is a relatively young field. What is considered “beautiful code” one day can be an anti-pattern the next. What if there was a way to write software that is easier to maintain, quicker to write, and more reusable by taking some timeless inspiration from the more established, culinary world?

In this talk we’ll take a look at the cooking term “Mise en place” (dealing with planning and preparation that goes into a meal) and how we can apply this concept to shared component libraries or design systems in our front end applications. We will examine how this strategy can help everyone on the team utilize these same ingredients to build, discuss, and design ultimately better software. While the examples are React-based, the concepts apply to other paradigms as well.

This talk will cover the basics of talking to the Slack API with a handful of Node libraries: node-fetch, ws, and express. I’ll show some incremental examples for building a (zombie horror) Choose-your-own-adventure app, and how the building blocks used for that can be extended to build a productivity app, namely an iCalendar processor that gives in-channel notifications when meetings are about to start.

We’ll cover:

• Creating personal Slack teams
• Granting auth to a new app
• Using await/fetch with bearer tokens for simple data collection and message posting
• Using WebSockets for real-time messaging
• Callbacks and triggers from user button clicks
• Registering slash commands
• Surviving the zombie apocalypse

As cloud providers take over more and more back end operations, organizations will increasingly have larger and larger percentages of their developers working on the front end. And it’s never been easier for front-end developers to build their own scalable applications without needing a back-end developer or operations teams. This talk will walk through the modern services that make all this possible, from Google Cloud’s Firebase to AWS’s Appsync, with specific action items any front-end developer can take to be completely self-sufficient.

We will not be having our regular meeting in December. Instead, we’ll have a holiday party with all the other meetups in town! Learn all about it and RSVP here.

There will be no November meeting this year as it lands on the day before Thanksgiving. So, Happy Thanksgiving and we’ll see you in December at the annual Holiday Party!

This session will begin with a brief introduction to NoSQL. Relational databases have worked on past projects. Why change now? Is NoSQL just a buzzword with no real substance? What can it do that relational can’t? What about all those horror stories and memes?

We’ll look at the best use cases for non-relational databases, how projects have succeeded and failed, and the tools and patterns for using NoSQL and SQL together. If scaling, flexibility, and speed are major concerns on your radar, or if you’re skeptical that the world needs anything but relational, then this session is for you.

This session will look at NoSQL through the lens of the characters from the Halt and Catch Fire TV show: Do you work with a “visionary” like Joe who thinks NoSQL will solve every problem? Are you an engineer like Gordon who doesn’t want to rush into it? Are you like Cameron and just want to smash the big establishment databases? Do you know a Tom who distrusts open-source? Or are you more like Donna and want to find a sensible approach that uses the best of both worlds? Come to this session to find out if you really need NoSQL.

The Processing Foundation is a group of arts educators that came together to make simple but powerful coding tools for making interactive art and 2D games with computers. Over the last few years, their efforts have focused on developing p5.js which is a versatile javascript library that has all the functionality of “Processing”, but in a browser environment.

Educators are starting to use p5.js to teach computer science, and importantly Dan Shiffman’s The Coding Train YouTube channel uses p5.js extensively. The STEMcoding project, led by Prof. Chris Orban at Ohio State, also uses p5.js to show kids how coding relates to science and math by using it to create 2D video games with simple physics. In 2017, the STEMcoding project launched a YouTube channel and created “The Physics of Video Games” activity on Hour of Code.

Prof. Orban will give an overview of the STEMcoding project and talk about possibilities for collaboration, for example, in the development of new coding activities that he would share with his educator network, and “Physics of Video Games” workshops at Columbus libraries.

Want to write a web application? Better get familiar with JavaScript! JavaScript has long been the king of front-end. While there have been various attempts to dethrone it, they have typically involved treating JavaScript as an assembly-language analog that you transpile your code to. This has lead to complex build pipelines that result in JavaScript which the browser has to parse and you still have to debug. But what if there were an actual byte-code language you could compile your non-JavaScript code to instead? That is what WebAssembly is.

I’m going to explain how WebAssembly works and how to use it in this talk. I’ll cover what it is, how it fits into your application, and how to build and use your own WebAssembly modules. And, I’ll demo how to build and use those modules with both Rust and the WebAssembly Text Format. That’s right, I’ll be live coding in an assembly language. I’ll also go over some online resources for other languages and tools that make use of WebAssembly.

When we’re done, you’ll have the footing you need to start building applications featuring WebAssembly. So grab a non-JavaScript language, a modern browser, and let’s and get started!

A JavaScript promise is a handy container for a value you expect to get later. But a promise is also a value itself, and you can do some useful stuff just knowing you have a promise.

Neal Lindsay works for Test Double, where he gets to help companies write software better. He likes Javascript unironically.

Writing clean, readable, front-end applications is often a challenge, and there are tons of frameworks and libraries that seek to solve this problem. One of the fastest growing solutions out there today is React. Developed by Facebook, React (and its companion library, Redux) is a highly scalable and elegant solution to many of javascript’s UI challenges. This talk will focus on the basics of how to get started in React, as well as some of the ideas behind writing clean and scalable React applications, and how to implement those ideas in large UI projects. It will also cover Redux, a state management library also developed by Facebook and built to work well with React applications.

From the Vue.js site:

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

WARNING: This is not another “React 101 - How to write Hello World in React” talk. By now, many of us have watched all the training videos and done all the tutorials, but what does it actually look like to bring a React application all the way to production? In this talk, we will explore what it takes to build a full-scale React application, from how to utilize the framework as a team, to setting up an end-to-end software pipeline.

Brandon Rockwell is a Columbus-based software consultant with 5+ years of experience working with many different technologies, and is always looking for new ways to bring JavaScript into the hearts and minds of our community.

Bigfoot has been a staple of American folklore since the 19th century. The stories originate from Native Americans in the Pacific Northwest and likely go back centuries or more. The term sasquatch itself is an Anglicized derivative of the Halkomelem word sásq’ets.

Many people are convinced that Bigfoot is real. Others suggest that he is a cultural phenomenon. Some just want to believe. There is even a group, the Bigfoot Field Researchers Organization, that tracks Bigfoot sightings. They have data— thousands of reports—available on the Internet. And, where there is data, we can apply the power of machine learning.

Let’s get to the bottom of this mystery! To do it, we are going to use the Nexosis Machine Learning API. With the API, we’ll forecast the predicted number of sightings for the coming months and years. We’ll measure the impact of key cultural phenomena—primarily the airing of the X-Files—on Bigfoot sightings. And, we’ll see if we can classify some bigfoot sightings of our own using natural language processing.

So, come and learn how to use the API, the types of problems you can solve with it, and how to use it from your favorite programming language.

The truth is out there.

The Chrome Developer Tools are absolutely packed with features. Some are incredibly useful. Some are just plain surprising. For example: Turn the browser into an editor, fuzzy search source filenames, display data in the console in tabular format and much, much more. In this session, we will fix up the storefront for Wacky Wanda’s Wicked Weapons and learn some console wizardry in the process. In the course of our tribulations we will correct styling problems, enhance our debugging skills, and clean up server-side snafus.

React and Angular 2 are getting a lot of buzz these days, but how do you decide which one to use? I took a small Rails app that I have in production and rewrote it using both Angular 2 and React. I’ll show you the code for the different versions, which will cover project setup, routing, validation, view syntax, JSX, handling query string parameters, managing state, Redux, Redux reducers, hot reloading, and testing. I’ll go over some pros and cons and things I like/don’t like that might help you decide which way to go.

Not just for offline, Service Workers allow your web app to give a snappy response and predictable behavior, so your web app “feels like an app” to your more-satisfied users.

Doug Reeder works at Chase as a software engineer.

For years front-end developers have bemoaned having to use the DOM; it’s slow, inconsistent, and difficult to use. While libraries of the past provided better ways to interface with the DOM, recent libraries like React and Vue have instead implemented an entirely new DOM: the virtual DOM. Implementations of the virtual DOM allow developers to create and maintain UI components using entirely declarative interfaces that completely abstract away the real DOM. In this session, attendees will unlock the power of the virtual DOM through a step-by-step tutorial on the creation of a virtual DOM implementation in roughly 100 lines of code. In doing so, they will gain a precise understanding of the advantages the virtual DOM provides to speed, maintainability, and testability.

Tools for modern JavaScript development are evolving very quickly in order to help developers deliver the types of experiences our users have come to expect. In 2017 and beyond, we have plenty of frameworks to choose from to build our next app. So how do you know which JavaScript framework to choose? What if you don’t have to? What happens if we use libraries and design patterns to build our applications instead of full blown frameworks? Let’s explore a way to build a JavaScript application by using event sourcing and pub/sub with stateless view components.

It seems like every day a new JavaScript framework is created. It can be overwhelming to keep up with all of them. This session will discuss some JavaScript packages that will make analyzing and displaying data a snap. We will discuss D3.js, CrossFilter.js, DC.js and jQuery DataTables. These are very robust community supported libraries. Use them in your client application to add interactive visualizations and data analysis tools.

Google Apps Script (GAS) is a JavaScript cloud scripting language that provides easy ways to automate tasks across Google products and third party services and build web applications. This talk is intended as an introduction to GAS and will cover a few example integrations.

Your Sets, Dictionaries and Graphs have a problem. It is difficult to merge changes made in your domain – especially if they happen simultaneously with shared data across nodes. This compounds once you consider disconnected apps and partitioned networks in or between data centers. Convergent Replicated Data Types solve these problems by allowing updates to arrive out of order, or even replayed without risk of corruption. You will be introduced to these data structures and given a tour of the tradeoffs and advantages of using them. While the technology is fairly new, libraries are cropping up across platforms. You’ll be ready to assess them and make decisions about what they might do for your domain.

In this session will talk about what is different about this generation of web applications and how a solid development approach must consider the latency, throughput and interactivity demand by users across both mobile devices, web browsers, and IoT. We will demonstrate how to include Couchbase in such applications to support a flexible data model and easy scalability required for modern development.

We will demonstrate how to create a full stack application focusing on the CEAN stack which is composed of Couchbase, Express Framework, AngularJS, and Node.js.

Scott will be presenting Hello World in an assortment of frameworks.

Come and learn about node-inspector.

Long ago, in the late days of the first Internet boom, before jQuery, before Underscore, before Angular, there was a web application built by a large corporation. This application was written as a server-side application using server-side technology like Java or PHP. A tiny seed of JavaScript was added to some of the pages of this application to give it a little sizzle.

Over the ages, this tiny bit of JavaScript grew like kudzu. Most of it was embedded in the HTML in SCRIPT tags. Some of it was dynamically generated by the server-side code. Browser specific hacks were added. An AJAX call was added. jQuery was added. Helper functions were added. Lots of helper functions. So many helper functions.

In time pyramids of doom built from anonymous callbacks and hundreds, nay, thousands of interdependent global functions ruled the day. And the programmers did despair. They cried to put the code under test that it might be refactored. “Add unit tests”, they exhorted. But, lo, there were no units to test, only anonymous functions.

Does this sound like your current application? I know I’ve worked on a lot of codebases just like this one. I’ve come up with some techniques to refactor them and put them under test (so the real refactoring can begin). In this session I will share them with you.

Josef will be talking about SauceLab and end-to-end automated testing.

Are you overwhelmed by JavaScript framework fatigue? Do you wish for the benefits of the newest front-end advancements without continually rewriting your application? Let’s take a look at the latest version of Ember. We’ll review the tooling, debugging, and addons that have made Ember a growing choice for innovative companies like Heroku, Travis CI, Square, and Nest. See how Ember adopts the best from other frameworks while bringing us the future of JavaScript today. You’ll leave this session with a clear understanding of how Ember fits into your front-end toolbox and why it might be the ideal choice for your next project.

More and more JavaScript libraries and client-side frameworks use promises to manage asynchronous data. But now you’re just using a .then() method to pass the same handler functions you did before. What is so great about that? Promises are not just a different place to specify callbacks. Learn about the significance of return values to promises, how promises can be composed, and helper methods provided by popular promise libraries for that purpose. You will also see common promise anti-patterns and how bringing callback-oriented thinking to promises can cause you to miss out on opportunities to simplify your code.

End the year hacking and celebrating. We’ll hang out, have a party, and maybe even write some code.

Hack! Share! Learn! We’ll be joining forces with the Arduino & Raspberry Pi Enthusiasts group to have another Hack Night.

Scott Preston will be bringing impressive things as he is wont to do. Guy Royse will be prepared to build ridiculous stuff with an Arduino, nodejs, and Johnny-Five.

You should bring something too!

Justin Searls will be speaking about his newest library – testdouble.js.

Don Abney will speak about and hack on the Intel Edison.

Lauren Kinsey will speak on diversity in technology.

Guy Royse will live code his way through another talk. This time talking about what promises are and how to use them. And, how to test them using Mocha and Chai.

Anyone who has written JavaScript knows how easy it is for the code to become a big ugly unmaintainable mess. Let’s stop dumping code into one big file, mixing responsibilities, and putting everything in global scope! JavaScript modules can help us keep our code clean, maintainable and testable. RequireJS and Browserify are the two most popular JavaScript module loading frameworks. They serve a similar purpose, but have drastically different implementations. In this talk we will introduce JavaScript modules, and compare the features and drawbacks of RequireJS and Browserify. Which one is right for your next project?

In June, we’ll have another Meteor hack night. Meteor is a complete open source platform for building web and mobile apps in pure JavaScript. We’ll be hacking and coding. Bring your machine, your ideas, and your brain.

Jason Karns will talk about why we don’t really need all these build tools and should instead give npm scripts a try.

Check out these articles: Why we should stop using Grunt & Gulp and How to Use npm as a Build Tool, both by Keith Cirkel.

ECMAScript most famous dialect is JavaScript, and the coming version is ECMAScript 6 (ES6). Browsers already started supporting some of its features. JS programmers need to start learning about the coming changes. The presentation will show some of ES6 most useful features like classes, block scope, collections, proxies, arrow functions, iterators, generators, comprehensions, and modules. We will concentrate on the practical aspects of the changes. The session will be interactive, includes many code examples, and will encourage audience participation. By the end of the presentation, participants will know when and how to use ES6 in their own projects.

Guy Royse will guide the group in test driven development with Testem and Jasmine.

Ben Gladwell will give a talk on Gulp.js. Gulp is a popular task runner/build tool. It’s powered by NodeJS and uses pipes for streaming data. There are a vast array of Gulp plugins available for tasks such as minifying code, uglifying javascript, watching files, and live-reloading the browser when files have changed.

Bluemix is a platform-as-a-service (PaaS) offering from IBM with roots deeply grounded in an open source project called Cloud Foundry. Javascript is a first class citizen when it comes to applications running on Bluemix.

The combination of Javascript and Bluemix allows developers to quickly build and deploy all types of applications to the public cloud in a matter of seconds. This talk will actually be composed of several smaller talks that show just how powerful Bluemixcan be.

We will start off with an introduction to Bluemix and show you the basics of using the platform. We will then walk you through how you would build and deploy a typical Node.js web application toBluemix. Finally, we will cover more advanced topics like the internet of things (IoT) and cognitive computing using Bluemix.

If you are at all interested in using a PaaS in your next project or want to learn about how a PaaS can change the way you build Javascript apps, we hope you will come and join us for a jam-packed evening that is sure to impress.

On Wednesday, September 17th, we are having a JavaScript Hardware Night. Bring your JavaScript powered hardware projects and share them with the group (if you like). Bring stuff to hack on and bring your ideas.

• Scott Preston will be bringing his robots.
• Doug Reeder is planning something with the Connect SDK.
• Guy Royse will share his work with Johnny Five, the Arduino, and Raspberry Pi.
• Keith McCanless might even have a JS Hardware talk prepared (hint, hint) around the Beaglebone.

The format will be loose. People who want to share their ideas will be given a screen to do it on. If you just want to hack, then pair up with some buddies and have at it.

Grunt is king. It is the ubiquitous task runner used for most nodejs projects and has quickly expanded to conquer other software ecosystems. However, its kingdom is vulnerable. Grunt does not align well with many nodejs paradigms and is notorious for its harsh learning curve. Meet Gulp, the challenger in the taskrunner revolution. Gulp’s easy configuration produces an easy learning curve, and its alignment with nodejs paradigms eliminates the friction. Grab your ticket, your foam finger, and your team-colored face paint and witness the battle, the revolution, and the crowning of Gulp.

The deck is already online, too at speakerdeck.com.

The key to quickly learning JavaScript MV* Frameworks is to break them down into a series of features. The main features of an MV* application are routing, data binding, templates/views, models, and data storage. In this talk, I’ll describe these main features and show code examples from two or three frameworks for each feature. You will begin to concretely understand what these frameworks are trying to help you accomplish and realize they are more alike than they are different. In fact, it becomes apparent that most of the frameworks borrow heavily from the successes of the others.
