Setting Up

Add the following code inside the <head> tag.

<script src="https://cdn.jsdelivr.net/npm/@editorjs/[email protected]/dist/editor.min.js"></script>
<script src="https://cdn.jsdelivr.net/gh/mdgaziur/EditorJS-LaTeX@latest/dist/editorjs-latex.bundle-min.js"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/mdgaziur/EditorJS-LaTeX@latest/dist/editorjs-latex.bundle.min.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.12.0/katex.min.css"></link>

To use with nodejs simply run npm i editorjs-latex and import using the following code:

const EJLaTeX = require('editorjs-latex');

To add this library to EditorJS, simply add the follwing code:

tools: {
        Math: {
        class: EJLaTeX,
        shortcut: 'CMD+SHIFT+M'
    }, ...
}

If you need to adjust the theming of the editor, you can add CSS rules in the config like:

tools: {
        Math: {
        class: EJLaTeX,
        shortcut: 'CMD+SHIFT+M',
        config: {
            css: '.math-input-wrapper { padding: 5px; }'
        }
    }, ...
}

Getting data

The output data of this plugin will look like bellow:

{
    "type" : "Math",
    "data" : {
        "math" : "\\frac{a \\pm b}{(a+b)^2}"
    }
}

The "math" item contains the expression. You can use KaTeX to render that in your document.
