React Components
React is component-based, meaning that everything is a component. For example, you could create a Button component like the one on Design+Code's home page. Components make the code easier to read and cleaner, as they are reusable throughout the website.
Component are JavaScript functions that contains JSX elements, which is a mix of Javascript and HTML. A simple function component looks like this:
import React from "react"
const MyButtonComponent = () => {
return <button>Sign in</button>;
}
export default MyButtonComponentLearn more about Components in the React Component section of this handbook.
React Hooks
React Hooks make React even simpler. Without writing a class, Hooks lets you control your functional component's state and lifecycle, as well as other features with only a few lines of code. For example, you can import the useState hook into your file and manage your component's state with it:
const [state, setState] = useState(initialValue)You can also manage your component's lifecycle with useEffect. This replaces the old componentDidMount, componentWillUpdate and componentWillUnmount.
useEffect(() => {
// code
}, [])Many other hooks are also available in React Hooks - you can even create your own custom hooks! Learn more about hooks in the following sections of this handbook:
- Understanding Hooks, to learn about the two rules of Hooks
- UseState Hook, to manage your component's state
- UseEffect Hooks, to manage your component's lifecycle
- UseRef Hook, to create a reference to an element in your application
- UseInput Hook, a custom hook to get the value a user inputs in an input field
Frameworks
React also comes with a many frameworks that you can use to create and deploy your project faster.
- Gatsby is a framework for React, and lets you create static content-oriented websites. It takes care of all the configuration for you. Complex websites can also be created with Gatsby - for example, the current Design+Code website was built on Gatsby. You can learn more on how to create your first Gatsby website in the Gatsby and React section of this handbook.
- NextJS is another framework that you can use to create a server-rendered website using Node.js. You can learn more about the NextJS by reading their documentation.
- Use Netlify to deploy your web application and let the world see your amazing work! It's easy to integrate Netlify with Github, and builds can be automatically triggered every time you push to your main branch.
Packages
React has tons of packages and libraries that you can utilize for purposes such as navigation, routing, UI components, animations, forms, and so much more! In these packages, everything is already coded for you and you simply need to use it! Some useful React packages are:
- React Toastify, to show custom alerts in your React application.
- React Helmet, to manage your document's head.
- React Lazyload, to lazy load your components and improve performance.
- Styled Components, to style your components in the same file as your JavaScript code.
If you're using Gatsby, more than 2500 plugins are also available to you. Here are some plugins that might interest you:
- Contentful, used as a Content Management System.
- Google Analytics, to measure your website's performance and track user engagement.
- Stripe, to integrate payments in your Gatsby application.
- Vimeo, to add videos to your Gatsby application.
