LteUrl – Link shortener | ReactJs, Node.js

Introduction

In today's digital age, link shortening has become a crucial tool for marketers, bloggers, and social media enthusiasts. Long URLs can be cumbersome, difficult to remember, and take up a lot of space. That's where link shorteners come into play. A link shortener is a service that reduces the length of a URL to make it more manageable and easier to share. In this tutorial, we will be building a simple link shortener using ReactJS and Node.js. We will use the LTEUrl library to shorten and redirect URLs.

What is LTEUrl?

LTEUrl is a simple and lightweight link shortener library for Node.js that provides a simple way to shorten and redirect URLs. It uses a unique identifier (called a token) to shorten the URL and redirects the user to the original URL when the shortened URL is accessed.

LTEUrl Features

Here are some of the key features of LTEUrl:

• Simple and lightweight
• Supports custom tokens and redirects
• Can be easily integrated with Node.js and ReactJS
• Supports URL encoding and decoding

Setting up the Project

To get started with this tutorial, you will need to set up a new ReactJS project. You can use a tool like Create React App to create a new project. Once you have created the project, create a new file called app.js and add the following code:

import React from 'react';
import ReactDOM from 'react-dom';
import { LTEUrl } from 'lte-url';

const lteUrl = new LTEUrl({
  tokenLength: 6, // Set the length of the token
  prefix: 'https://example.com/' // Set the prefix for the shortened URL
});

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      originalUrl: '',
      shortenedUrl: ''
    };
  }

  handleShorten = () => {
    const originalUrl = document.getElementById('original-url').value;
    lteUrl.shorten(originalUrl).then((shortenedUrl) => {
      this.setState({ shortenedUrl });
    });
  };

  render() {
    return (
      <div>
        <h1>Link Shortener</h1>
        <input id="original-url" type="text" placeholder="Enter the original URL" />
        <button onClick={this.handleShorten}>Shorten</button>
        <p>Original URL: {this.state.originalUrl}</p>
        <p>Shortened URL: {this.state.shortenedUrl}</p>
      </div>
    );
  }
}

ReactDOM.render(<App />, document.getElementById('root'));

This code sets up a simple ReactJS component that allows the user to enter an original URL and shortens it using LTEUrl. The shortened URL is then displayed on the screen.

LTEUrl Integration

To integrate LTEUrl with your ReactJS application, you will need to install the LTEUrl library using npm or yarn. Once installed, you can import the library and create a new instance of the LTEUrl class.

In the code above, we create a new instance of the LTEUrl class and pass in an options object that specifies the token length and prefix for the shortened URL.

Shortening a URL

To shorten a URL using LTEUrl, you can call the shorten method and pass in the original URL as an argument. The shorten method returns a promise that resolves with the shortened URL.

In the code above, we call the shorten method and pass in the original URL entered by the user. We then update the state of the component with the shortened URL.

Redirecting to the Original URL

To redirect the user to the original URL when they access the shortened URL, you can use the redirect method provided by LTEUrl.

Here is an example of how you can use the redirect method:

const lteUrl = new LTEUrl({
  tokenLength: 6,
  prefix: 'https://example.com/'
});

lteUrl.redirect('https://example.com/abc123').then((originalUrl) => {
  console.log(originalUrl); // https://example.com/original-url
});

This code redirects the user to the original URL when they access the shortened URL (https://example.com/abc123).

Conclusion

In this tutorial, we have learned how to use LTEUrl to shorten and redirect URLs using ReactJS and Node.js. We have also seen how to integrate LTEUrl with our ReactJS application and use the shorten and redirect methods to shorten and redirect URLs.
