Managing state in modern web applications is hard. As applications grows in complexity, keeping track of state changes and mapping those changes back to your UI becomes increasingly difficult.

One way data flow makes managing state more approachable and lightens the cognitive load required to follow the flow of data through your application. Using Redux takes this idea to the next level and moves the state and the state changes and centralizes them in a global store, managed with pure reducer functions.

In this course you will learn how to build a production quality React application using Redux. We will build up from using redux by itself, so we can understand the core API and how that interacts with a React application, then we’ll move on to introduce react-redux to abstract away some of the underlying details and clean up our code. We’ll use middleware and a mocked API server to understand how asynchronous code fits into the Redux model and we’ll even deploy our finished work so we can see it running live in the cloud.map react redux
Many React Native developers came to mobile development from a background of web development (like me). That’s one of the reasons React Native is appealing — it’s so much like the web.

But because of this we often have a gap of knowledge, namely around bringing the app to production. The web has its challenges but mobile development has a different set of challenges — challenges we may not necessarily be familiar with.

I know this is something I struggled with so I wanted to put together a quick checklist of tasks you can use to successfully bring your React Native app to production.react
What designers need to know about these transformational layout tools.

CSS has come a long way since its introduction in 1996, but the tools we have available for layout haven’t changed much. Table layouts were incredibly too rigid, float-based layouts were basically a hack, positioning-based layouts were not adaptable, and none could handle a great deal of complexity in an efficient way. Don’t get me wrong — these methods got us really far, but they aren’t intended for complex layout purposes.

The short-comings of these old methods for layout have become even more apparent with responsive web design, in which embracing the fluidity of the Web is fundamental.

With flexbox and grid, we finally have tools intended specifically for layout that are more efficient and void of hacks necessary with previous layout methods. They unlock new possibilities to old problems, enable things that weren’t possible before, and solve real problems we face with responsive web design.
GraphQL is a language. If we teach GraphQL to a software application, that application will be able to declaratively communicate any data requirements to a backend data service that also speaks GraphQL.

Just like a child can learn a new language fast, while a grown-up will have a harder time picking it up, starting a new application from scratch using GraphQL will be a lot easier than introducing GraphQL to a mature application.

To teach a data service to speak GraphQL, we need to implement a runtime layer and expose it to the clients who want to communicate with the service. Think of this layer on the server side as simply a translator of the GraphQL language, or a GraphQL-speaking agent who represents the data service.

This layer, which can be written in any language, defines a generic graph-based schema to publish the capabilities of the data service it represents. Client applications who speak GraphQL can query the schema within its capabilities. This approach decouples clients from servers and allows both of them to evolve and scale independently.ecoders graphql

Redux is an excellent tool for managing the “state” of an application. The unidirectional flow of data and the focus on immutable state makes reasoning about changes to the state simple. Each update to our state is caused by a dispatched action, which causes our reducer function to return a new state with the desired changes. Many of the user interfaces we create with Redux at AppNexus deal with large amounts of data and very complex user interactions as our customers manage their advertisements or publishing inventory on our platform. Over the course of developing these interfaces, we have arrived at some helpful rules and tips to keep Redux manageable. The following points of discussion should help anyone working with Redux on large, data intensive applications:redux
If you’re a web developer, chances are you’re going to have to write some CSS from time to time.

When you first looked at CSS, it probably seemed like a breeze. You added some borders here, changed some colors there. JavaScript is the hard part of front end development, right?

Somewhere during your progression as a web developer, that changed though! What’s worse is that many developers in the front end community have come to dismiss CSS as a toy language.

The truth however is that when we hit a wall, many of us don’t actually understand what our CSS is doing under the hood.javascript unity
Flexbox, named also flexible box, is a new layout mode introduced in CSS3, which defines how elements are arranged in a page so that they behave predictably under different screen sizes and devices.

It is called Flexbox because of its high flexibility in controlling the behaviour of elements. Compared to the old layout methods like display table and floating inline blocks, Flexbox is much more powerful way to:

  • Lay out elements in different directions
  • Rearrange display order of elements
  • Align elements to different position
  • Dynamically fit elements into container
In this course, we will incorporate react-intl into a project created with create-react-app and react-router. The react-intl library makes complex tasks such as internationalization and formatting dates & currency incredibly simple. Another huge benefit of react-intl is that it gives you the ability to centralize the content across your application into language specific files. This creates a consistent place to find content and encourages reuse. If you’ve ever used language specific yml files in Rails, you’re already familiar with this pattern.

Starting with the entry point of the application, we will hit the ground running by adding the necessary components and data structures required for react-intl to function. From there, we will use react-intl components to format various types of data including strings, dates, and numbers. We will also work through writing tests for components that include react-intl components using Jest and enzyme.react test

Google runs lots of different systems, and they all store data about you. There's the search engine itself, of course, which knows what you've been looking for on the web. Then there's Youtube, Blogger, Calendar, your Google Drive, Hangouts, Gmail and more.

If you want to download a copy of all the data about you that's held on Google's servers, it's actually surprisingly easy. This is really useful if, say, you have a lot of important messages in your Gmail account and you want to ensure that you have a local copy. Just in case something happens to your Google account and you can no longer access them.

The key to all your data is a site called Google Takeout, which you'll find at https://takeout.google.com/settings/takeout. Just go there, log in if you haven't already done so, and then select which data you want to download.

It’s essential to divide JavaScript and CSS code into small and concise parts. We make it easier for ourselves and others to manage it, and also to understand and maintain it later. Browsers on the other hand, prefer as few files as possible. They can be long and space-less as long as they’re few. This is where Webpack comes in.

Webpack is the go-to web development tool nowadays for getting all of your CSS and JavaScript files to become one. The result is often referred to as a «bundle». In this article I will show you how to set up a basic environment for JavaScript and Sass.javascript
“Bad programmers worry about the code. Good programmers worry about data structures and their relationships.” — Linus Torvalds, creator of Linux

Data structures are a critical part of software development, and one of the most common topics for developer job interview questions.

The good news is that they’re basically just specialized formats for organizing and storing data.

I’m going to teach you 10 of the most common data structures — right here in this short article.

I’ve embedded videos that I created for each of these data structures. I’ve also linked to code examples for each of them, which show how to implement these in JavaScript.news javascript
Recently, there was a lot of fuss on Twitter regarding the current state of ES modules, especially in Node.js, which decided to introduce *.mjs as file extension. The fear and uncertainty is understandable since the topic is complex and following the discussions takes a high degree of effort and dedication.javascript node
If, like myself, you’ve ever created a website using the “standard” tools of plain old HTML or templates, preprocessed CSS, and JavaScript, then you may also have shared the same delight I did when React came along and offered a way to easily break a website or app into manageable, reusable chunks.

This also came at a time when JavaScript was maturing immensely, going from what some considered a “toy language” to one of the most popular languages out there today. After promises came on the scene we could forget about writing sideways pyramids and getting ourselves into callback hell. Then along came async/await, and now most of us try to avoid those “messy and confusing” promise chains wherever possible. We are spoiled, literally, for choice.

Then along came Flux, after that Redux. State management just got a whole lot easier, and although you might not always need it, Redux is often the go-to state management tool for a lot of developers. That little extra initial setup often goes a long way and saves us major headaches further down the line.

s the language evolves so fast it’s hard to keep track of all the new features, so this article is about my personal opinion on how to make the best use of them to improve your components without sacrificing anything whatsoever.

I should point out here that in all my examples I’ll be using React Native, but the principles are exactly the same in React… So let’s get into it!react redux javascript
