react-mathjax-jbs v0.0.3

React MathJax

React component to display math formulas written in AsciiMath or TeX.

Install

npm install react-mathjax2 --save

Usage

Inline display of AsciiMath wrapped in delimiters

import MathJax from 'react-mathjax2'

const ascii = 'U = 1/(R_(si) + sum_(i=1)^n(s_n/lambda_n) + R_(se))'
const content = `This can be dynamic text (e.g. user-entered) text with ascii math embedded in \$\$ symbols like $$${ascii}$$`

module.exports = () => {
    return (
        <MathJax.Context
            input='ascii'
            onLoad={ () => console.log("Loaded MathJax script!") }
            onError={ (MathJax, error) => {
                console.warn(error);
                console.log("Encountered a MathJax error, re-attempting a typeset!");
                MathJax.Hub.Queue(
                  MathJax.Hub.Typeset()
                );
            } }
            script="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=AM_HTMLorMML"
            options={ {
                asciimath2jax: {
                     useMathMLspacing: true,
                     delimiters: [["$$","$$"]],
                     preview: "none",
                }
            } }
        >
            <MathJax.Text text={ content }/>
        </MathJax.Context>
    );
}

Inline display of AsciiMath without delimiters

import MathJax from 'react-mathjax2'

const ascii = 'U = 1/(R_(si) + sum_(i=1)^n(s_n/lambda_n) + R_(se))'

module.exports = () => {
    return (
        <div>
            <MathJax.Context input='ascii'>
                <div>
                    This is an inline formula written in AsciiMath: <MathJax.Node inline>{ ascii }</MathJax.Node>
                </div>
            </MathJax.Context>
        </div>
    );
}

Block display of AsciiMath

import MathJax from 'react-mathjax2'

const ascii = 'U = 1/(R_(si) + sum_(i=1)^n(s_n/lambda_n) + R_(se))'

module.exports = () => {
    return (
        <div>
            <MathJax.Context input='ascii'>
                <div>
                    <MathJax.Node>{ascii}</MathJax.Node>
                </div>
            </MathJax.Context>
        </div>
    );
}

Inline display of LaTeX

import MathJax from 'react-mathjax2'

const tex = `f(x) = \\int_{-\\infty}^\\infty\\hat f(\\xi)\\,e^{2 \\pi i \\xi x}\\,d\\xi`

module.exports = () => {
    return (
        <div>
            <MathJax.Context input='tex'>
                <div>
                    This is an inline math formula: <MathJax.Node inline>{'a = b'}</MathJax.Node>
                </div>
            </MathJax.Context>
        </div>
    );
}

Block display of LaTeX

import MathJax from 'react-mathjax2'

const tex = `f(x) = \\int_{-\\infty}^\\infty\\hat f(\\xi)\\,e^{2 \\pi i \\xi x}\\,d\\xi`

module.exports = () => {
    return (
        <div>
            <MathJax.Context input='tex'>
                <div>
                    <MathJax.Node>{tex}</MathJax.Node>
                </div>
            </MathJax.Context>
        </div>
    );
}

API

MathJax.Context props

script (String)

• Loads specified link with MathJax library.
• Default: https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-MML-AM_CHTML

input (String)

• Sets type of input.
• Options: tex | ascii
• Default: ascii

delay (Number)

• Sets delay between updates.
• Default: 0 (the main difference between this library and react-mathjax from SamyPesse)

options (Object)

• Sets MathJax configuration.
• Default: Official MathJax configuration

onLoad (Function)

• Triggered after MathJax script finishes loading (but BEFORE children are allowed to render if noGate is set to false)

onError (Function)

• Triggered when any Math Processing Error occurs

noGate (Boolean)

• Defaults to false, controls whether to disallow rendering of children components until the MathJax script has finished loading
