ReactJs is a popular framework used by developers across the globe to build engaging & robust web applications. For frontend developers it is the first choice to build highly interactive user interfaces. While working on the framework, the developers must be careful to perform things in tune keeping React best practices in mind. This will help to keep the code better organized. As we already aware of, React is a library build & managed by Facebook allowing integration with several interesting components. In fact, any developer can build its own components and make them publicly accessible. This blog post is all about the most fundamental of the React best practices:
1. Keep Components Small
As we all know, with ReactJs Development Services, huge components can be integrated to execute multiple tasks. But according to experts keep components small, so that one component defines one function. There are many advantages associated with it:
- Each small component is reusable across different projects.
- Components can be made available to the community.
- Small components help with performance optimizations.
- It takes less time to update smaller components.
2. Reusability of Components
We mentioned earlier one function is defined by one component; this improves the reusability of components. This clearly states that you should skip building a new component for a function if there is already a component available for that function. With the reusing of components across your project, not only consistency is achieved but a contribution is also made to the community. Furthermore, if any component becomes huge and difficult to manage, it’s better to slice it up into as many smaller components as possible.
class IconButton extends React.Component {
[…]
render() {
return (
<button onClick={this.props.onClick()}>
<i class={this.props.iconClass}></i>
</button>
);
}
}
3. Keep Code Concise
A common rule that developers very well know is to keep the code as brief and concise as possible. It’s no different here as well, since ReactJs UI Development Services also instruct to keep code brief as well as precise. One method to perform this is to avoid duplication of the code. You can easily achieve this by inspecting the code for patterns as well as similarities. If you find any, chances are high you’re repeating code and it can be easily removed. Most likely, a bit of rewriting can make it briefer. This relies heavily on the ReactJs reusability principle.
const buttons = [‘facebook’, ‘twitter’, ‘youtube’];
return (
<div>
{
buttons.map( (button) => {
return (
<IconButton
onClick={doStuff( button )}
iconClass={button}
/>
);
} )
}
</div>
);
4. Add Necessary Comment
Make sure to add comments to code only where required. This is not only the part of React best practices; it also serves two important objectives at the same time:
- It will help to keep the code visually clutter free.
- No conflict between comment and code will occur, if you alter the code at some later point of time.
5. Put CSS in JavaScript
When you hire top ReactJs Developer to start working on a project, they usually keep all the CSS styles in a single SCSS file. The usage of the global prefix avoids any sort of potential name collisions. But once your project scales up, this solution is of no use. There are multiple libraries allowing you to write CSS in JS. EmotionJS and Glamorous are the two most popular CSS in JS libraries.
You can understand it with the use of EmotionJS in your project. It can generate complete CSS files for your production. Initially, install EmotionJS using npm.
npm install – save @emotion/core
Next, you need to import EmotionJS in your application.
import { jsx } from ‘@emotion/core’
You can set the properties of an element as shown in the snippet below:
let Component = props => {
return (
<div
css={{
border: ‘1px’
}}
{…props}
/>
)
}
So, these are some of the top ReactJs best practices that need to be properly followed for building interactive user interfaces for user engagement & remain competitive.
Frequently Asked Questions
1. Why is ReactJS so popular?
The core objective of ReactJS is to provide the best possible rendering performance. Its strength comes from the focus on individual components. Instead of working on the entire web app, ReactJS allows a developer to break down the complex UI into simpler components.
2. Is it worth learning React in 2020?
ReactJS is very easy to learn and more focused than some other JavaScript framework. Many businesses are shifting or adopting the React library because of the simplicity it provides and ease of use. Ease of Learning React is the best advantage as compared to other popular front-end frameworks like Angular and Vue.
3. Is ReactJs better than Angularjs?
Prompt rendering is among the best features of React that gives a significant edge over Angular. The core difference between Reactjs and Angularjs is that React is JS-centric, while Angular 2 remains HTML-centric. JavaScript is far more robust, than HTML that makes ReactJs far more simple, focused and consistent.
4. Do you assure about security & confidentiality of the idea?
Yes, we sign a strict NDA to protect your application idea & data. Hence, we ensure complete security and privacy of your application development project.
