📚 A free book that talks about design patterns/techniques used while developing with React.

If any JavaScript project has taken the front end ecosystem by storm in recent years, that would be React. React is a library built and open-sourced by the smart people at Facebook. In React, developers write components for their web interface and compose them together.

React

I'm debugging an application which uses React.js, the Chrome Extensions list clearly shows that the React Developer Tools are installed, and when i access the React site at http://facebook.github.io/react/ i can clearly see a "React" tab in the developer tools window. Yet when i'm debugging my application i see this in the console:

I am building an Isomorphic Application in React which first renders a component server-side, then takes advantage of React's intelligent re-rendering browser-side.

Uncaught TypeError: Property 'CommentList' of object [object Object] is not a function In fact react.js's own examples page has:

I'm using react/react-redux/react-router/react-router-redux.

I use webpack's code splitting feature (require.ensure) to reduce the initial bundle size of my React application by loading components that are not visible on page load from a separate bundle that is loaded asynchronously.

I'm using ReactJS to render text values into contenteditable DOM nodes. Eg:

For example: here is an Todo app build only with React and here is an Todo app build with Flux and React.

Using something like Vitest, Jest, or Mocha didn't work because:

MochaJS is a feature-rich JavaScript test framework running on Node.js, making it a popular choice for both backend and frontend testing. It's known for its flexibility and straightforward syntax, allowing for asynchronous testing and the use of any assertion library.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

JavaScript Popular tools for testing: Mocha, Jasmine, Unit JS, Jest

To execute your tests, you can create test scripts using popular testing frameworks like Mocha, Jasmine, or Jest. These frameworks provide a structured way to organize and run your tests, report results, and handle assertions.

⚗️ Mocha and Chai for testing

Testing frameworks like Jest, Mocha, and Jasmine are crucial for software development, ensuring code reliability and correctness. They offer features like test suites, test cases, assertions, and asynchronous testing support.
