Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

React MathJax

npm version

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

Example of usage

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)

onLoad (Function)

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

onError (Function)

noGate (Boolean)

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