Test Driving a React js UI Component

ver the past decade, eXtreme Programming practices like Test-Driven Development (TDD) & Behaviour Driven Developer (BDD), Refactoring, Continuous Integration and Automation have fundamentally changed software development processes and inherently how engineers work. While TDD has seen a great adoption on server side, developers still find it hard to apply TDD for developing UI components.

In this hands-on, live coding demo, Naresh will build a web commenting and discussion feature (like Disqus) in React.js, 100% test driven. He will also demonstrate how TDD will help us drive an object-functional design to strike a pragmatic balance between the Object-Oriented and Functional Programming paradigms.

JavaScript for IoT devices with Smart.js

Sergey Lyubka (https://twitter.com/cesanta_cto) tells about building a JS engine to run on tiny embedded devices. Cesanta (https://www.cesanta.com/) has developed a world's smallest JS engine and aims to bring JS environment to the most constraint embedded environments, making IoT (Internet of Things) development available to the large audience of JS programmers. Of course, there are certain specifics about embedded programming, which I am going to describe.

Make JS better, JS compiler

Slides at http://jsdocedjs.org/docs/stepbystep-slides/

Jerome Etienne (https://www.twitter.com/jerome_etienne) gave us a talk on his JSdoced compiler. Javascript is used a lot in compilers these days. People build new languages and make them compile to javascript. But, what about compiling javascript to javascript? Could we make javascript better this way?It turns out that we can! I am going to talk about about just that. How to compile javascript to javascript to make your javascript better.

You can do this using Jsdoced.js. Jsdoced.js will automatically extract jsdoc from your code. Using your jsdoc comments, it will generate another javascript file which makes sure your jsdoc is respected during execution. The more you documents your code, the safer it becomes. http://jsdocedjs.org/

Django and React: Perfect Together

slide: https://docs.google.com/presentation/d/1TRgDA-fImXTj88eeNW37iokt4ehuK8Q6Y-7hZnBqW4g/

React is a JavaScript library that makes it much easier to build dynamic single-page sites. I won't much dive into how React works, but the main advantage is that it allows you to build your view layer in a declarative way, and with reusable components.

We'll start with an overview how React works, with an eye towards how it's different from interpretive libraries like jQuery. This overview will center around how state is managed in React vs. jQuery, which is the biggest hurdle for many developers when they're learning React. So if you haven't quite wrapped your head around the difference between "2-way data binding" and "1-way data binding", or if you've heard someone talk about "data-down/actions-up", "flux", or "redux" and weren't quite sure what they were talking about, this will clear all that up.

Then we'll take a look at how you can integrate React into a Django project. We'll talk about how you might want to structure things if you're starting with a brand new project, but we'll also talk about ways you can start to take advantage of React's strengths even in projects that are already mature.

Finally, we'll talk about some of the challenging parts of working with React for the first time - how to handle front-end permissioning in React based on your back-end API, how to think about url routing when you literally have two routers, deployment, and the general confusion that goes along with using npm and webpack for the first time.

Beyond Po: How to Make Django Work For Right-To-Left Languages

LANGUAGE DETECTION

How to address URL based translation and Django language detection easily.

RTL LANGUAGE DIRECTION

Most of them are speaking in a language which is written right to left so it’s not enough to just translate your app to their language. You should change the style of your app to display them in a correct format. Some graphic elements should be flipped horizontally to make sense for them.

CHARACTER ENCODING ISSUES

When you are working with a language with completely different form of alphabet and characters there is a huge chance that you face an issue if you don’t abide some encoding standards.

CALENDAR SYSTEM

Some of those countries have their own calendar which is completely different from gregorian calendar which is used in most of west countries. There are some apps helping you to convert unix timestamp to those different calendar format in both backend and frontend side

INTERFACE DESIGN AND PROPER FONTS

As their language is RTL some graphic elements need to be mirrored. Although it is true for most of layout parts but there are still some sections that needs to keep their direction, like mathematical equations, multimedia players progress bar, … Using modern frontend tools like SASS mixin to automatically float elements depending on the language direction.

Functional Programming Basics in ES6

With all the hubbub over functional programming in JavaScript land, you might be confused what it’s all about. Let’s look at the problems that functional programming can solve more elegantly than imperative programming. We will see why functional programming is an important tool in our bag by enforcing modularity and readability, making code more understandable and easier to test.

Creating Cross-Platform Apps with Angular 2

In the early goals of Angular 2, we focused on creating a full platform that encompasses even more of the needs of our developer community. Mobile is all the rage these of late, but the majority of successful product teams have investment across web, mobile web, installed mobile apps and even installed desktop applications. From individual developers all the way to CIOs, folks would like to reuse both their development expertise and their code across these platforms to deliver quickly and at minimal cost. Please join us for a chat on how we're addressing this full space of development needs in Angular 2.

High-Availability Django by Frankie Dintino

One year ago we completed a years-long project of migrating theatlantic.com from a sprawling PHP codebase to a Python application built on Django. Our first attempt at a load-balanced Python stack had serious flaws, as we quickly learned. Since then we have completely remade our stack from the bottom up; we have built tools that improve our ability to monitor for performance and service degradation; and we have developed a deployment process that incorporates automated testing and that allows us to push out updates without incurring any downtime. I will discuss the mistakes we made, the steps we took to identify performance problems and server resource issues, what our current stack looks like, and how we achieved the holy grail of zero-downtime deploys.

JavaScript Software Craftsmanship

Becoming an expert coder involves much more than learning the coolest new framework or becoming a design pattern ninja. Becoming an expert coder is about passion and craftsmanship.
