OAuth 2.0 OpenID Connect Loopback and Keycloak

Question

I'm unable to connect to Keycloak from Loopback.

I've been trying to use the keycloak-connect lib:

https://github.com/keycloak/keycloak-nodejs-connect

This is my current server/boot/root.js

module.exports = function (server) {
    var session = require('express-session');
    var Keycloak = require('keycloak-connect');

    var memoryStore = new session.MemoryStore();

    var keycloak = new Keycloak({
        store: memoryStore
    });

    server.use(session({
        secret: 'xxx',
        resave: false,
        saveUninitialized: true,
        store: memoryStore,
    }))

    server.use(keycloak.middleware({}));

    server.get('/*', keycloak.protect(), function (req, resp) {
        resp.send('hello');
    })

};'

Seems quite simple but it gets stuck in a redirection loop.

I've also tried swapping

server.use(session

with

 server.use(keycloak

But then see "Cannot read property 'keycloak-token' of undefined"

Been stuck on this for a while and tried everything. Any other ideas?

Thanks in advance!

It seems that you might need to tell your Keycloak instance to use the Memory Store you create when you initialize it, like so:

var keycloak = new Keycloak({ store: memoryStore });

Hope that fixes the problem.
