keycloak-helper

a small helper service for NodeJS apps to authenticate to Keycloak

usage hints

Use it in two steps.

1. install in node app directly from github npm install --save https://github.com/KomMonitor/keycloak-helper
2. require helper service let keycloakHelperService = require('kommonitor-keycloak-helper');
3. initialize helper service parameters required to perform keycloak authentication services keycloakHelperService.initKeycloakHelper(authServerUrl, realm, clientId, clientSecret, kommonitorAdminUsername, kommonitorAdminUserPassword, kommonitorAdminRolename)
4. perform authentication action, by either calling
   • requestAccessToken() to request an access token as a KomMonitor Admin user
   • getRolesFromKeycloakToken(token) to request role names of a valid submitted keycloak token
   • isAdminUser(token) to request whether the submitted keycloak token resolves to a user with KomMonitor admin rights
   • checkKeycloakProtection(req, res, next, method) as express middleware in order to intercept any incoming requests and perform keycloak protection checks for KomMonitor i.e. as should be integrated as the first middleware when instantiating express like so:

       let app = express();
   
       app.use(async function(req, res, next) {
           // intercept requests to perform any keycloak protection checks.
           await keycloakHelperService.checkKeycloakProtection(req, res, next, "POST");
       });
