Why Convert HTML to Plain Text?

There are multiple reasons why developers may need to convert HTML into text using Node.js:

Convert HTML to Text Using Node.js

One of the simplest ways to convert HTML into plain text in Node.js is by using the replace() function with a regular expression. This allows us to remove all HTML tags efficiently.

Example Code:

var myHTML = "<div><h1>Shubham Mishra</h1>\n<p>That's what she said regarding</p></div>";

var strippedHtml = myHTML.replace(/<[^>]+>/g, '');

console.log(strippedHtml);

Output:

Shubham Mishra

That's what she said regarding

This method effectively removes all HTML tags, leaving only the plain text content.

For more advanced conversions, the html-to-text package can be used. Install it via npm:

npm install html-to-text

Usage example:

const { convert } = require('html-to-text');
const html = "<div><h1>Node.js HTML to Text</h1><p>This is an example.</p></div>";
const text = convert(html);
console.log(text);

2. Using cheerio for More Control

If you need more control over the HTML parsing process, you can use cheerio:

npm install cheerio

Example:

const cheerio = require('cheerio');
const html = "<div><h1>Hello World</h1><p>This is a test</p></div>";
const $ = cheerio.load(html);
const text = $('body').text();
console.log(text);
