[NodeJS] Open API generator for nodejs with middleware (how to implement it nicely)

Is your feature request related to a problem? Please describe.

In the generated code of NodeJS Server, is there a way we can implement a middleware?

Describe the solution you'd like

I want to implement a middleware that intercepts requests after openapi router successfully validates the request, it will only run on specific controllers ie. JWT validate base on stored tokens in MongoDB like the ones we do on normal nodejs server:

route

router.get('/users/me', auth, async(req, res) => {
    // View logged in user profile
    res.send(req.user)
})

auth

const jwt = require('jsonwebtoken')
const User = require('../models/User')

const auth = async(req, res, next) => {
    const token = req.header('Authorization').replace('Bearer ', '')
    const data = jwt.verify(token, process.env.JWT_KEY)
    try {
        const user = await User.findOne({ _id: data._id, 'tokens.token': token })
        if (!user) {
            throw new Error()
        }
        req.user = user
        req.token = token
        next()
    } catch (error) {
        res.status(401).send({ error: 'Not authorized to access this resource' })
    }

}
module.exports = auth

Describe alternatives you've considered

I could create a service to manually call the verification of token on every controller/service that i want it to be validated but I think it is redundant and not really clean

No files or tests are named. Start by locating the NodeJS server generator and its generated OpenAPI router, then trace how requests reach controllers and services. Done would require a decided, documented approach for applying authentication middleware after validation to selected controllers.
