app.httpServer = http.createServer(app);
// ...
app.use(cookieParser());
app.use(drupalExpressMiddleware('local.my-website.com', knex));

`

then in your routes
`javascript
const { drupalUserAccess, drupalCSRFToken } = require('express-drupal7-session-middleware');

const myRoute = async (req, res) => {
const access = await drupalUserAccess(knex, 'access api myRoute', req.userId);
if (!access) {
return res.status(403).send();
}

// Bonus if you need it
console.log(req.cookieSessionText);
// -- and --
const drupalHashSalt = 'fwf3qfwgrbq34h34qeg134g3434g5340f-0f';
const csrfToken = await drupalCSRFToken(knex, req.sessionId, drupalHashSalt, 'services'));
res.json({ csrfToken });
