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

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 '='
