otpauth-uri-parser

A simple function for parsing otpauth:// URIs.

It uses the global URLSearchParams object, so this will only work in modern browsers and node >= 10 or with an appropriate polyfill.

This is based on the specs here so there might be some corner cases not covered.

Usage

It's pretty simple.

const parseURI = require('otpauth-uri-parser');

const parsed = parseURI('otpauth://totp/Example:[email protected]?secret=JBSWY3DPEHPK3PXP&issuer=Example');

console.log(parsed);

// Gives us:
{
    type: 'totp',
    label: { issuer: 'Example', account: '[email protected]' },
    query: { secret: 'JBSWY3DPEHPK3PXP', issuer: 'Example' }
}

Note: numeric query string parameters are not converted to numbers. So if the URI has digits=6 you will get { digits: '6' } in the query object and not { digits: 6 };

Contributing

If you encounter an otpauth:// URI that this fails to parse as expected please open an issue and ideally create a merge request with a failing test case.
