passport-jwt-mock

Mock passport JWT strategy for testing a Node.js application.

This module allows you authenticate a fake user in a Node application using your existing passport-jwt implementation to allow for easy testing of routes.

Install

Install using yarn:

$ yarn add passport-jwt-mock --dev

Or npm:

$ npm install passport-jwt-mock --save-dev

Usage

To get started you can import MockStrategy and create a new instance. I believe the easiest approach is to use an environment variable to hot-swap the regular jwtStrategy with the mock strategy.

const passport = require("passport");

let jwtStrategy = null;
if (process.env.NODE_ENV === "test") {
	jwtStrategy = require("passport-jwt-mock").Strategy;
} else {
	jwtStrategy = require("passport-jwt").Strategy;
}

Once you have replaced the the jwtStrategy object, you are nearly done! The implementation (however you used it) will work without modifying the implementation.

passport.use(
	new jwtStrategy(
		{
			//secret we used to sign our JWT
			secretOrKey: 'secret',
			//we expect the user to send the token as a query paramater with the name 'secret_token'
			jwtFromRequest: ExtractJWT.fromAuthHeaderAsBearerToken()
		},
		async (token, done) => {
			try {
				//Pass the user details to the next middleware
				return done(null, token.user);
			} catch (error) {
				done(error);
			}
		}
	)
);

Important Note

This package is for testing purposes only! Please do not use this for actual authentication as it provides no security whatsoever!
