Testing

Manually tested config definitions in local application:

import { ConfigParams, SessionCookieConfigParams } from "./express-openid-connect";

const appSessionCookieConfig: SessionCookieConfigParams = {
  sameSite: 'Lax'
};

const oidcConfig: ConfigParams = {
  appSessionCookie: appSessionCookieConfig,
  appSessionDuration: 234567890,
  appSessionName: 'banana',
  appSessionSecret: [ process.env.APP_SESSION_SECRET ],
  auth0Logout: false,
  authorizationParams: {
    response_type: 'code',
    scope: 'openid profile email'
  },
  baseURL: process.env.BASE_URL,
  clientID: process.env.CLIENT_ID,
  clientSecret: process.env.CLIENT_SECRET,
  clockTolerance: 60,
  errorOnRequiredAuth: false,
  getUser: (req, config) => {
    if (!req[config.appSessionName] || !req[config.appSessionName].claims) {
      return null;
    }
    return req[config.appSessionName].claims;
  },
  handleCallback: async (req, res, next) => next(),
  httpOptions: {},
  identityClaimFilter: ['aud', 'iss', 'iat', 'exp', 'azp', 'auth_time'],
  idpLogout: true,
  idTokenAlg: 'RS256',
  issuerBaseURL: process.env.ISSUER_BASE_URL,
  legacySameSiteCookie: true,
  loginPath: '/login',
  logoutPath: '/logout',
  redirectUriPath: '/callback',
  required: false,
  routes: true
};

app.use(auth(oidcConfig));

Just rearranging in this file.

Why is appSessionSecret required in this new typedef when it can pulled from APP_SESSION_SECRET?
