Requires

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const jwt = require('express-jwt');
const jwks = require('jwks-rsa');
const request = require('request');

Authentication

app.post('/authenticate', (req, res) => {
    const username = req.body.username; //Username or email
    const password = req.body.password;

    const options = { method: 'POST',
        url: 'YOUR_AUHT0_API_URL/oauth/token',
        headers: { 'content-type': 'application/json' },
        body: { 
            grant_type: 'password',
            username: username,
            password: password,
            audience: YOUR_AUDIENCE,
            scope: 'read:sample',
            client_id: YOUR_CLIENT_ID,
            client_secret: YOUR_CLIENT_SECRET },
        json: true 
    };

    request(options, function (error, response, body) {
        res.status(response.statusCode).json(body);
    });
});

Authorization

const jwtCheck = jwt({
    secret: jwks.expressJwtSecret({
        cache: true,
        rateLimit: true,
        jwksRequestsPerMinute: 5,
        jwksUri: "YOUR_AUHT0_API_URL/.well-known/jwks.json"
    }),
    audience: 'YOUR_AUDIENCE',
    issuer: 'ISSUER',
    algorithms: ['RS256']
});

app.get('/protected', jwtCheck, (req, res) => {
    res.json({message: 'authorized'})
});
