Genarate A Link Preview With Node Js

 In This Blog, I will show you how to implement link preview using link-preview-js and node js. link preview js is free library its work on node (back-end environments) and certain mobile run-times (cordova or react-native).

Implementing link previews involves extracting metadata from the target URL, such as Open Graph metadata, which is commonly used by social media platforms and other websites to structure the information shared via URLs. This metadata includes details like the title, description, and image associated with the webpage.

To create a link preview feature, developers often use server-side programming languages like Node.js to fetch and process the metadata from the target URL. Libraries such as link-preview js help in efficiently extracting this metadata. Once the metadata is obtained, it can be displayed in a visually appealing format on the client side, providing users with a preview of the linked webpage.

Link previews are commonly used in messaging apps, social media platforms, and other web applications to improve user engagement and provide context when sharing links. They help users make informed decisions about whether to click on a link by offering a glimpse of what they can expect to find on the linked webpage.

link preview with Node.js can be a useful feature for displaying previews of links shared within your application. 

Here's how you can do it

Step 1 : Install Package

npm i link-preview-js

Step 2: Create Index.js file

Create an index.js file copy and paste this code 

const { getLinkPreview } = require("link-preview-js");

async function init() {

    try {

        const response = await getLinkPreview('https://github.com/', {

            imagesPropertyType: "og", headers: {

              "user-agent": "googlebot",

              'Accept-Language': 'en-US'

            },

            timeout: 10000

          });

          console.log(response)

    } catch (error) {

        console.error(error);

    }

}

 

init();

Step 3 : Run Your Node.js Application

Use the node command followed by the name of your JavaScript file to run your Node.js application

node index.js

That's it! You now have a basic implementation of a link preview generator using Node.js. You can extend this further based on your requirements and preferences.
