If you’re a Melbourne web developer studying React, you’ve probably already spent a lot of time watching tutorials, taking courses, and creating apps. Do you ever feel like you’re stuck? We’re here to assist you! We asked our developers for their finest React recommendations to help beginners become masters.
Because React is our primary frontend framework, our frontend team is constantly keen to discuss it. Furthermore, the creators present a variety of viewpoints, some more technical and others more focused on the learning process.
Utilize functional elements
A component is a JavaScript function or class that accepts optional inputs (props) and returns HTML using the render () function. React components are self-contained and reusable code pieces.
There are two sorts of components: class components and functional components.
Class components are basic stateful classes with internal state and life cycle methods. Functional components have no state. It may, however, be used as a stateful component by utilising react hooks. Props are passed as arguments to the functional components, which return React elements.
Developer tools for React
React developer tools come in helpful while working on a React project. It knows the component hierarchy, properties, and children, as well as the state of the component and assists with debugging.
React developer tools make it easier for developers to design dynamic user interfaces. New features are added on a regular basis. It’s an essential tool for inspecting React applications.
Avoid Using State (If Possible)
React state keeps track of the data, which causes the React component to re-render when the data changes. Avoid utilising state as much as possible when designing React applications since the more state you use, the more data you have to keep track of across your project.
Declaring state only when necessary is one technique to reduce its usage. If you’re getting user data from an API, instead of saving individual properties, keep the entire user object in the state.
Increase the reusability of your code
Thinking broadly about the project and its upkeep is one of the major characteristics of an accomplished developer. When developing functionality for a single component, keep in mind that comparable functionality may exist (or may exist) elsewhere in the system.
Nothing is more irritating than duplicating code snippets across several components. The ideal approach to put the above guideline into practise on a daily basis is to use react functional components, which allow you to use and create your own hooks! This allows us to share the same logic across react components, which makes your code more legible, reusable, and tidy.
Organize files for the same component in a single folder
When choosing a project structure, choose one that is component-centric. This involves keeping all files related to a single component in a single folder.
Create a folder named navbar that contains the Navbar component, the style sheet, and any JavaSript and asset files required in the component if you’re making one. It’s simple to reuse, distribute, and debug a component using a single folder containing all of its files. You simply need to access one folder if you want to examine how a component works.
Create unit tests for methods and component rendering
Tests are necessary, but many developers hate writing them.
When utilising redux-thunk for state management, you may have more lines of code in actions, which is crucial functionality, thus it’s nice to have the appropriate tests. Why? When it’s time to restructure your code, tests will let you know whether you’ve broken anything. When you need to make a change, start by changing your test and then your implementation. Then you may rest assured that nothing will break as a result of the modifications.
Tests of your components are also crucial. To begin, all you have to do is create an abstract component rendering test.
Always consider a variety of solutions
Before implementing a solution, attempt to come up with other options. It frequently highlights flaws that you would otherwise only see while implementing. Discussing implementation ideas with someone or working with a TDD (test-driven development) approach is a good idea.
