htmlstring-to-react

Why ?

This module provide an easy way to parse a string containing html elements to an array of React elements. It tries to focus to security (using DOMPurify) and keeping the bundle as small as possible

It is heavily inspired by html2react and html-react-parser

How to install ?

npm install htmlstring-to-react
// or
yarn add htmlstring-to-react

How to use ?

Simple example

import { parse } from 'htmlstring-to-react'
parse('<em key="1"><b key="2">It\' is working</b></em>')

Add an override

You can use css selectors to override an element

import { parse } from 'htmlstring-to-react'
parse('<b key="1">It</b> is <b key="2">working</b>', {
  overrides: {
    b: (props, textContent) => <b onClick={console.log('Click')}>{textContent}</b>
  },
})

All valid css selectors works

import { parse } from 'htmlstring-to-react'
parse('<b key="1">It</b> is <b key="2" class="active">working</b>', {
  overrides: {
    'b.active': (props, textContent) => <b onClick={console.log('Click')}>{textContent}</b>
  },
})

IMPORTANT Overrides do not support nested elements in the current stage, so this code

import { parse } from 'htmlstring-to-react'
parse('<b key="1"><b key="2">It is working</b></b>', {
  overrides: {
    b: (props, textContent) => <b onClick={console.log('Click')}>{textContent}</b>
  },
})

will drop the inner b but keep the textContent

Change dom parsing configuration

By default, we are sanitizing the html input using DOMPurify module. You can override the configuration we are using

import { parse } from 'htmlstring-to-react'
parse('<b key="1">It</b> is <b key="2" class="active">working</b>', {
  dom: {
    ADD_TAG: ['script']
  },
})

IMPORTANT You cannot override RETURN_DOM, RETURN_DOM_FRAGMENT and RETURN_DOM_IMPORT because they are used internaly by the library.

Other options

  • useFragment (default false): Return a Fragment instead of an array.
  • useAsKey (default ['key']): Ordered list of attributes to use as a key. Use the first one that matches or null
