react-mathjax-preview

react-mathjax-preview provides one React component to render MathML, TeX or ASCIImath formulas. See demo.

Installation

Install react-mathjax-preview as a dependency:

npm install react-mathjax-preview

Usage

Import the package and fill the math property with some text containing your formals. Wrap TeX in $ or $$ and ASCIImath in `. Paste MathML as is.

import React, {Component} from 'react'
import {render} from 'react-dom'
import MathJax from 'react-mathjax-preview'

const asciimath = '`sum_(i=1)^n i^3=((n(n+1))/2)^2`' # Because of the backtick
const math = String.raw`
  <math xmlns="http://www.w3.org/1998/Math/MathML" display="block">
    <menclose notation="circle box">
      <mi> x </mi><mo> + </mo><mi> y </mi>
    </menclose>
  </math>

  $$\lim_{x \to \infty} \exp(-x) = 0$$

  ${asciimath}`

class Demo extends Component {
  constructor(props) {
    super(props);
    this.state = {
      math: tex
    }
  render() {
    return <MathJax math={this.state.math} />
  }
}
