passport-auth-jwt v1.0.22

passport-auth-jwt

A Passport strategy for authenticating with a JSON Web Token.

This module lets you authenticate endpoints using a JSON web token. It is intended to be used to secure RESTful endpoints without sessions.

Install

npm install passport-auth-jwt

Usage

Sorry this is a personal library for locking my system. And I to open the handler requirements.

The flow

User <-> Device <-> Provider

Note:

• User This is your user
• Device This is your application/website
• Provider This is your system, RESTful endpoint

Configure

/**
* Config
*/
var passport = require('passport');
var passportAuthJWT = require('passport-auth-jwt');
config.passport.hook = require('./helper/auth-jwt-hook');
var PassportMoney = new passportAuthJWT(config.passport);
passport.use(PassportMoney.strategy());

Authenticate requests

Use PassportMoney.authenticate() specifying 'JWT' as the strategy.

app.post('/profile', PassportMoney.authenticate({ session: false}),
    function(req, res) {
        res.send(req.user.profile);
    }
);
