Fetching and Parsing Meta Tags from URLs in Node.js

Fetching and Parsing Meta Tags from URLs in Node.js

Fetching and parsing meta tags from web pages is a common task in web development, particularly useful for SEO analysis, content summaries, or social media integration. JavaScript, with Node.js, provides a powerful and efficient way to accomplish this. In this post, Ill guide you through creating a simple Node.js script to fetch and extract meta tags from any URL.


Before diving into the code, ensure you have Node.js installed on your machine. Youll also need two npm packages: Axios for making HTTP requests and Cheerio for parsing HTML content.

Step 1: Installing Dependencies

First, install Axios and Cheerio by running the following command in your terminal:

npm install axios cheerio

Step 2: Writing the Script

Our script will consist of a function fetchMetaTags that takes a URL, sends a GET request, and parses the HTML to extract meta tags.

const axios = require('axios');
const cheerio = require('cheerio');

async function fetchMetaTags(url) {
    try {
        const { data } = await axios.get(url);
        const $ = cheerio.load(data);
        const metaTags = {};

        $('meta').each((i, element) => {
            const name = $(element).attr('name') || $(element).attr('property');
            if (name) {
                metaTags[name] = $(element).attr('content');

        return metaTags;
    } catch (error) {
        return { error: error.message };

// Example usage
fetchMetaTags('https://www.google.ca').then(metaTags => console.log(metaTags));

Step 3: Understanding the Code

  • Axios: Makes the HTTP GET request to the URL.

  • Cheerio: Parses the HTML content and provides a jQuery-like syntax for traversing and manipulating the HTML elements.

  • Meta Tags Extraction: Iterates over each meta tag and stores their name (or property) and content in an object.


With this simple script, you can start fetching meta tags from any web page using Node.js. This method is particularly useful for SEO purposes, content discovery, and more.

Remember to use web scraping responsibly and always comply with the terms of service of the websites you scrape.

Next Steps

  • Expand the script to handle different types of meta tags more specifically.

  • Integrate this functionality into larger web applications or SEO tools.
