RData Auth Server

Based on Express, Passport and JWT

Warning

This software is currently in it's beta stage. The newest versions might (and most likely will) break the backwards compatibility.

Usage

const app = require('rdata-auth-server');
app.run();

The auth server is a simple authentication server that uses different providers (passport strategies) to authenticate a user and issue access and refresh tokens. Both access and refresh tokens are JWT tokens that contain encoded user information. That information includes provider name, user id, user name, email, and provider-specific data.

Access token is a short-term token that can not be revoked. It can be set as POST parameter or body JSON parameter named "accessToken". It can also be set using "Bearer" HTTP header. Refresh token is a long-term token that also contains information about the session. This token can be revoked from the database. It can be set as POST or JSON body parameter named as "refreshToken".

Third-party server (for example, data collection server) can check the access token in it's own authorization routine.

API

Default local strategy:

POST /api/v1/auth/local/register

Registers new local user in the Mongo database

Parameter	Description	Example
username	User name of the new user. Must contain alphanumeric symbols, whitespace, underscore and dot.	testuser
email	User email. Must be a valid email.	[e-mail]
password	User password. Must be at least 6 symbols.	p@$$W0r.d

Result: Returns new registered user:

{
  "user": {
    "id": "58d3e07395b64c28f020217c",
    "email": "[e-mail]",
    "username": "test",
    "role": "user"
  }
}

otherwise, returns ValidationError and 400 status code.

---

POST /api/v1/auth/local/authenticate

Authenticates local user

Parameter	Description	Example
username	User name or email.	testuser or [e-mail]
password	User password	p@$$W0r.d

Result: Returns refresh and access tokens.

{
  "refreshToken": "REFRESHTOKEN1234 (usually longer)",
  "accessToken": "ACCESSTOKEN1234 (usually longer)"
}

otherwise, returns 401 Unauthorized

---

Strategy-agnostic API:

POST /api/v1/auth/revoke

Revokes the refresh token

Parameter	Description	Example
refreshToken	Previously issued refresh token	REFRESHTOKEN1234 (usually longer)

Result: Returns 200 OK with result:

{
  "result": "ok"
}

otherwise, returns 401 Unauthorized

Providing custom authentication strategies

You can extend the functionality of the express app by adding your custom middleware to the default router called api:

const app = require('rdata-auth-server');
const express = require('express');
 
const router = new express.Router();
router.post('/authenticate', function(req, res, next) {
    res.json({"result": true});
});
app.api.use('/customAuth', router);
 
app.run();

This example will create /api/v1/customAuth/authenticate route. If you want to ignore the default api version and provide your own, use app.app.use (app.app exposes Express app object).
