> A library to parse "attachment"s in Content-Disposition.
## Getting started
### Install via npm
```sh
npm install content-disposition-attachment
```
#### ESM
```js
import { parse } from 'content-disposition-attachment';
console.log(parse('attachment; filename=foo.html'));
// => { attachment: true, filename: 'foo.html' }
```
#### CommonJS
```js
const { parse } = require('content-disposition-attachment');

```
#### ESM

## API references
### parse
> Parse a Content-Disposition.
If Content-Disposition is not "attachment", it returns `{ attachment: false }`;
otherwise, it returns `{ attachment: true }` along with parsed parameters.
If errors occur when parsing parameters, a `ParseError` will be thrown.
**Examples**
```js
import { parse } from 'content-disposition-attachment';
parse('inline');
// => { attachment: false }
parse('attachment; filename=foo.html; foo=bar');
// => { attachment: true, filename: 'foo.html', foo: 'bar' }
parse('attachment; foo');
// => ParseError: expect '='
```
You can find more examples in the [unit tests](test/parse.js).
