passport-strategy-runner

What is it?

This lets you run a Passport strategy without having Passport involved:

import { BasicStrategy } from 'passport-http';
import { runStrategy } from 'passport-strategy-runner';
 
const strategy = new BasicStrategy((username, password, done) => {
  done(null, {username: 'jwalton'});
});
 
const req = {};
 
// If no callback is supplied, will return a promise.
runStrategy(strategy, req, (err, result) => {
    expect(req.user.username).to.equal('jwalton');
});

Why would you want this?

Maybe you want to write unit tests for your strategy, maybe you want to make a passport competitor that works with Passport strategies, maybe you just decided you wanted to figure out how Passport works. :)

API

runStrategy(strategy, request[, options][, done])

Runs the specified strategy, with the specified request and the specified options. options here is the options object that would be passed to passport.authenticate(strategy, options). If you do not pass a callback to this function, it will return a Promise which resolves to the result. The result will be an object of one of the following forms:

• {type: 'success', user, info}
• {type: 'fail', challenge, status, message, messageType}
• {type: 'redirect', url, status}
• {type: 'pass'}
