Passport Account Token Strategy

code style: prettier

A passport.js strategy for authenticating by a token passed in the URL params or the request header.

When offering a public API, a simple way of authenticating a request is by requiring a client to pass a token that is stored against a particular user. The clients requests then act on behalf of the user who owns the unique token.

This library provides a passport.js strategy that extracts a token from a specified header or URL parameter and allows you to verify it with your own implementation code.


Create the strategy with an options object and a "verify request" callback. This callback allows you to check the extracted token with your own logic, such as a database lookup.


  • headerKey - [this or urlParamKey must be provided]. A single string representing a HTTP header name to extract a token from.
  • urlParamKey - [this is headerKey must be provided]. A single string representing the URL parameter key to extract a token from.

One or more of the above options must be specified. Only specified keys will be used to extract a token. For example, if the urlParamKey is not provided then you cannot use this to pass your token.

  • passReqToCallback - Instructs the strategy to pass the full Express Request object through to the verify callback.

The verify callback lets you decide whether to authenticate a request or not. It is called every time a request uses this strategy. It will be supplied the extracted token and a passport.js done callback. You can optionally get the full express request object as well.

var passport = require('passport');
var Strategy = require('passport-account-token').Strategy;

var options = {
    headerKey: 'authorization',
    urlParamKey: 'token'

passport.use(new Strategy(options, (token, done) => {
    let user = null;

    // Replace the following with your custom authentication logic,
    // you might wish to lookup the "token" in a database for example.
    if (token === 'abc123') {
        user = { username: 'test' };

    // Return a "user" object representing the user. This will
    // later be attached to the req.user object by Passport.js.
    done(null, user);

If you wish to be given the full express request object, you can set the passReqToCallback option to true.

var passport = require('passport');
var Strategy = require('passport-account-token').Strategy;

var options = {
    headerKey: 'authorization',
    urlParamKey: 'token',
    passReqTocallback: true // Instruct the strategy to give you the req.

passport.use(new Strategy(options, (req, token, done) => {
    // You now have access to the "req" object from Express.

    let user = null;

    // Your custom authentication logic...
    if (token === 'abc123') {
        user = { username: 'test' };

    done(null, user);


This project is written in TypeScript, to run the tests you must first run a build of the TypeScript.

Installing dependencies

$ yarn install

Building the project

$ yarn build

Running tests

Tests are written in JavaScript so we can test edge cases that the TypeScript and TSNode compilers don't allow (such as not providing required fields).

$ yarn test
