extract-mdx-metadata

Extract MDX metadata without using babel or webpack loaders.

Installation

NPM

$ npm i extract-mdx-metadata

Yarn

$ yarn add extract-mdx-metadata

Usage

Say we have the following file, example.mdx:

import something from 'something';

export const meta = {
    prop: 'value',
};

# Title

Content.

And our script, example.js, looks as follows:

const fs = require('fs');

const extractMdxMeta = require('extract-mdx-metadata');

(async () => {
    const path = 'example/example.mdx';
    const content = fs.readFileSync(path);
    const meta = await extractMdxMeta(content);

    console.log('meta', meta);
})();

Now, running node example yields:

meta {
    prop: 'value'
};

You can try this yourself by downloading or cloning the project, installing dependencies, and running yarn example.
