express-accesstoken-validation

ExpressJS middleware for remote access token validation

Although JWT have become common use in OAuth 2.0 / OpenId Connect scenarios, there a scenarios where you as an resource server (=API) have to validate an access token received by the client.
This validation normally is delegated to the OAuth 2.0 server which created that access token.

express-accesstoken-validation is an ExpressJS middleware that lets you delegate the access token validation to an OAuth 2.0 server like oauth2-server.

Installation

npm install express-accesstoken-validation --save

API

const bearerTokenValidation = require('express-accesstoken-validation');

let options = {
  validationUri: 'https://localhost:3000/oauth/tokenvalidation',
  tokenParam: 'token',
  unprotected: ['/public']
}

app.use(bearerTokenValidation(options));

options provides this options:

• validationUri: The access token validation uri of the OAuth 2.0 server
• tokenParam: The name of the token query parameter expected by the OAuth 2.0 server
• unprotected: optional, a list of routes that should not be protected

Make sure to register express-accesstoken-validation as the first middleware to ensure all requests get authorized.
