Without further ado, let’s dive right in!
What is React?
React is an open-source JavaScript library created by Facebook to fuel the UIs of applications, especially SPA applications where the webpage content changes frequently.
React enables developers to come up with reusable UI components, thus enhancing the efficiency, speed, and reliability of development lifecycles.
In order to enhance performance and avoid frequent rendering of the entire DOM tree, React uses a virtual DOM (Document Object Model). React’s declarative paradigm allows developers to create simple views for each state in the application and with efficient management of the component tree, only the necessary components are updated when data changes.
Due to its versatility, speed and impressive community, it is one of the most popular frameworks.
What are React code snippets?
React code snippets are pre-written chunks of code meant to be used in the React library for:
- Speeding up the development cycle.
- Ensuring there’s uniformity and standardization.
These snippets can be anything — from basic components to hooks and from complex functions to state management patterns. These play a cardinal role in quickly implementing some of the most popular constructs in the code, reducing the overall time that would have been spent writing monolithic, erroneous code.
Leveraging code snippets in React, hence, makes developers adhere to the best practices, maintain code consistency, and boost the development pace significantly.
React code snippets are available via snippet management tools or extensions in code editors such as VS Code, which are pretty easy to integrate into the development processes.
Why do you need a snippet management tool?
A snippet management tool is an essential software, helping devs to store, sort, and retrieve code snippets.
Such a tool improves personal productivity, boosts documentation, and encourages collaboration with the help of team version control. Below, we’ve outlined four reasons why developers should use a snippet management tool.
- Efficiency
Snippet management tools are used by developers to search for and paste ready-made pieces of code instead of writing a new code. This is advantageous for development since developers can concentrate on coming up with solutions and features without having to factor in other aspects.
2. Consistency
Storing code snippets in a common place helps make sure that the code used is standard across the various projects. This is to avoid making wrong choices and also to ensure that the code being used is tested and proven to be correct. It also assists in enforcing code quality across the development teams.
3. Knowledge-sharing:
These tools help in sharing code snippets that may be useful for a team as well as for the developer community. This helps enhance the team spirit and it takes advantage of all the brains in the team to look for coding errors that can be seen by all the members of the team.
4. Learning and growth:
One way of keeping up to date with current trends is by using and reviewing code snippets in a snippet management tool. Sometimes, it can be useful for programmers to have a reference of what kind of code is considered good and standard to follow and enhance their understanding of the language.
7 essential react code snippets to try out in 2024
1. Functional Components with Props
As a top-of-the-crop building block in React apps, it helps create reusable components for UIs. Look at the snippet below:
import React from ‘react’;
const MyComponent = (props) => {
return <div> {props.message} </div>;
};
export default MyComponent;
2. List Rendering
Renders items in a list, mostly from an API or database, to be displayed on the user interface, ideal for displaying a list of items. Look at the snippet below:
import React from ‘react’;
const List = ({ items }) => {
return (
<ul>
{items.map(item => (
<li key={item.id}>{item.name}</li>
))}
</ul>
);
};
export default List;
3. Forms
React code that handles forms and input submission, ideal for creating a form for user input. Look at the snippet below:
import React, { useState } from ‘react’;
const Form = () => {
const [value, setValue] = useState(‘’);
const handleChange = (e) => setValue(e.target.value);
const handleSubmit = (e) => {
e.preventDefault();
// Handle form submission
};
return (
<form onSubmit={handleSubmit}>
<input type=”text” value={value} onChange={handleChange} />
<button type=”submit”>Submit</button>
</form>
);
};
export default Form;
4. Custom Hooks
Creates a hook for reusing stateful logic, ideal for fetching data from an API with reusable logic. Look at the snippet below:
import { useState, useEffect } from ‘react’;
const useFetch = (url) => {
const [data, setData] = useState(null);
const [loading, setLoading] = useState(true);
useEffect(() => {
const fetchData = async () => {
const response = await fetch(url);
const data = await response.json();
setData(data);
setLoading(false);
};
fetchData();
}, [url]);
return { data, loading };
};
export default useFetch;
5. Modal Component
A component for displaying overlay modals, suitable for displaying a notification modal. Look at the snippet below:
import React from ‘react’;
const Modal = ({ isOpen, onClose, children }) => {
return isOpen ? (
<div className=”modal”>
<div className=”modal-content”>
{children}
<button onClick={onClose}>Close</button>
</div>
</div>
) : null;
};
export default Modal;
6. Tabs Component
A tab component for switching between different content, perfect for implementing tabbed navigation for different sections of a page. Look at the snippet below:
import React, { useState } from ‘react’;
const Tabs = ({ tabs }) => {
const [activeTab, setActiveTab] = useState(0);
return (
<div className=”tabs”>
{tabs.map((tab, index) => (
<div
key={index}
className={`tab ${index === activeTab ? ‘active’ : ‘’}`}
onClick={() => setActiveTab(index)}
>
{tab.title}
</div>
))}
<div className=”tab-content”>{tabs[activeTab].content}</div>
</div>
);
};
export default Tabs;
7.Image Slider Component
An image slider for displaying multiple images, tailored for creating an image carousel. Look at the snippet below:
import React, { useState } from ‘react’;
const ImageSlider = ({ images }) => {
const [currentIndex, setCurrentIndex] = useState(0);
const nextSlide = () => setCurrentIndex((prevIndex) => (prevIndex === images.length — 1 ? 0 : prevIndex + 1));
const prevSlide = () => setCurrentIndex((prevIndex) => (prevIndex === 0
images.length — 1 : prevIndex — 1));
return (
<div className=”slider”>
<button onClick={prevSlide}>Prev</button>
<img src={images[currentIndex]} alt=”Slide” />
<button onClick={nextSlide}>Next</button>
</div>
);
};
export default ImageSlider;
