Writing Easily Testable Code with Stateless Components in React.js

Writing Easily Testable Code with Stateless Components in #React.JS  #javascript #testing

  • The use of Stateless Functional Components (a.k.a. “pure” or “dumb” components) in React.js continues to grow since first it was released in React 0.14, and for good reasons.
  • By relying on pure components, developers end up writing reusable code that’s extremely easy to test, which leads to better application architecture.
  • Personally, I like the term “pure component” because it’s indicative of what the code really is — a pure function sprinkled with some JSX.
  • In addition to these benefits, pure components also make it extremely easy to test code with any crazy props that you wish.
  • As we just saw, the code for functional components provides us awesome intel for everything we need to know in order to write effective tests.

Functional Stateless Components provides clean syntax that allows us to write more declarative code. We will look at stateless components and finish up with some unit tests in this article.

Using JSX and React  #React #reactjs #javascript #Framework #programming

  • You use JSX within React code to easily create components for your apps.
  • Here is an example of JSX being used to render HTML:

    To create a component, just use a local variable that starts with an upper-case letter, e.g.:

    Note: There are reserved words in JSX, as it is essentially JavaScript after all—so keywords such as and are discouraged as attribute names.

  • Form creation is easy with JSX and sub-components, for example:

    To make this work, you must create the sub-components as attributes of the main component:

    To use some JavaScript to create a result for use in an attribute value, React just needs you to wrap it in curly braces like so:

    You can also just pass a boolean value for form attributes such as , and so on.

  • First we use to establish signalling of a new user connected via the as so:

    Then, to connect to the PeerServer, we use the following:

    We then listen for events via the method:

    We also have our JSX inside components in the directory.

    Once the push is finished, you will be able to start your web service with the following:

10 Amazing Apps that are Built using React Native

10 amazing #mobileapps that are built using #ReactNative.

  • Before team Bloomberg adopted React Native for their mobile app development, they had to spend significant time in developing and updating the versions of iOS and Android app individually.
  • Although React Native covers a small part of this app, it adds a significant experience for the users in terms of UI and UX.
  • Their iOS and Android apps share 98% of the code, which is an amazing example of how React Native can help in cross-platform app development.
  • The examples shared above elucidates that React Native has got potential for mobile app development, with any scale, any idea, with any type of content.
  • If you too have an app idea that this amazing technology can do justice to, check out more about our React Native development services.

React Native use modern web techniques for mobile app development. Here is a list of 10 amazing apps that are built using React Native technology.
