Container Components and Stateless Functional Components in React – Zsolt Nagy

  • Let’s introduce functional components: – – has become a function with a argument, returning the return value of the method of the original implementation.
  • Implications of the structure of stateless functional components: – – In the introduction, I mentioned that stateless functional components come with performance benefits.
  • Typically, container components have the following properties: – – The rule of thumb for choosing the appropriate syntax for React components is the following: – – then it is advised to use stateless functional components.
  • Let’s put theory into practice, and transform all the stateless component in our chat application into functional components.
  • Reviewing the conditions for modeling a component with a function, we can see that there is absolutely nothing preventing us from creating a functional equivalent of the class.

We will now introduce another way to define simple components. You will not only write less code, but you will also benefit from performance optimizations done by React. Let’s introduce functional components:

Clean Code vs. Dirty Code: React Best Practices

Clean code vs. dirty code: React best practices  #ReactJS

  • This article will focus on clean code practices as they apply to modern React software development.
  • Many React developers rely on Jest for a zero-configuration test runner and to produce code coverage reports.
  • And don’t discount the “rewrite factor” and time spent fixing comments from code reviews.
  • The advantage of letting React set your prop defaults, however, is that it produces more efficient code, defaults props in a based lifecycle component, as well as allows your default values to be checked against .
  • For example, the following component is ripe for converting to an SFC. – – The clean version clears a lot of the screen clutter of the dirty version.

Clean code is a consistent style of programming that makes your code easier to write, read, and maintain. Discover how to make your React code cleaner using easy-to-follow examples.

The Road to learn React

  • All JavaScript ES6 features I describe on the journey to learn React will transition from ES5 to ES6 in the book.
  • The book does not only teach React, but also all useful JavaScript ES6 features for React.
  • I encourage developers to reach out after they have finished the book and build their first React applications.
  • This book focuses on React as the first building block.
  • It only delivers the view layer, but the React ecosystem is a whole flexible and interchangeable framework.

The Road to learn React is your way to learn ReactJs in 2017 by building a real world application. You will get a foundation before you dive into more advanced topics like Redux, Flow and React Router. It’s a huge tutorial …

Porting enterprise React app to create-react-app – Mihir Karandikar – Medium

  • The short term goal was to see how difficult it is to move the legacy code to CRA; the long term goal being bringing all of our applications under CRA’s fold.The reason for choosing CRA over any other boilerplate is that CRA is truly unopinionated which makes it ideal for porting legacy React applications.
  • Removing all relative imports likeimport * as actions from module-like imports import * as actions from ‘actions/MyActions’And finally write a new build process on our build server since CRA recommends using Yarn.That meant, a decision was to be made!We were debating over ejecting the create-react-app setup Vs. using custom react-scripts.
  • But then I realized that ejecting would make it nearly impossible to keep up with the daily updates of CRA, which meant that custom react scripts was the best way to go.
  • Things were looking good.I’m not going to go in the implementation details of migration, but the purpose of my post is to let others know that it is absolutely possible to port your app to CRA no matter how weird your legacy app setup is.With the power of CRA + custom react scripts, we now TRULY have a zero configuration tool in our tool-belt.
  • From now on, to migrate/create the next app, all we need to do is create-react-app my-app –scripts-version xoxo-react-scriptsand we’re off and running!Things to keep in mindTo my disappointment, CRA does not come with react-hot-loader.

So I’ve been writing React apps for a year now. I’ve had the honor of being one of the maintainers of react-boilerplate. If you’re a React developer, you know how it is- You get the mock-ups, you get…
