Full documentation: https://github.com/Blagoj5/html-converter#readme
Installation
npm install html-converter-js
yarn add html-converter-jsUsage
Javascript code:
import { htmlConverter } from 'html-converter-js'; // ES6
const { htmlConverter } = require('html-converter-js'); // ES5
const element = document.querySelector('#test-p');
const text = '<p>Paragraph</p>';
const textEls = '<p>Paragraph</p><p>Second paragraph</p>';
const dangerousText = '<p>Paragraph<script></script></p>';
// Two ways:
// 1
const [newlyCreatedEl, cleanedData] = htmlConverter(text, 'p'); // If you provide HTML tag -> it will create the specified element and it will append the sanitized text into that element. Drawback: you have to automatically add it to the element you want
element.appendChild(newlyCreatedEl);
// or
element?.insertAdjacentElement('beforeend', newlyCreatedEl);
// or just add the cleaned/sanitized string you want like this
element?.insertAdjacentHTML('beforeend', cleanData); // newTag is not valid because of jsdom and because im not testing it on an actual browser env
// 2
const [_, cleanedData] = htmlConverter(text, element); // If you pass the element itself it will append the sanitized text using insertAdjacentHTML into that element. The first element of the returned array is the element itself.
console.log(`Sanitzed text: ${cleanedData} has been added to element ${element}`);For html:
<html>
<head>
<title>My Notes</title>
<link href="style.css" rel="stylesheet" />
</head>
<body>
<h1>My App</h1>
<p id="test-p"></p>
