# 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:
```js
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`.
## API
### `extractMdxMeta(content, [options])`
Parses content and returns the metadata object.
#### options
Type: `Object`
##### `defaultReturnValue`
Type: `*`
Default: `{}` (empty `Object`)
The value returned if the content does not contain any metadata.
