Token-Creator NodeJS

const app = require('express')(),
  env = require('dotenv').config(),
  JWT = require('jsonwebtoken'),
  bodyParser = require('body-parser');

// support parsing of application/json type post data
app.use(bodyParser.json());

//support parsing of application/x-www-form-urlencoded post data
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/token', (req, res) => {
  const payload = {
    userType: req.body.userType || ''
  };
  // console.log('env', env.parsed.AUTHY_SECRET); // This can be any in any environmental variable for yonja

  const Token = JWT.sign(payload, env.parsed.AUTHY_SECRET, {
    algorithm: 'HS256',
    expiresIn: '24h',
    subject: 'authy_verification'
  });
  return res.json({ Token });
});

app.listen(env.parsed.PORT || 3000, function () {
  console.log('Server is running at 3000');
});

Create env file and add AUTHY_SECRET and its value like [AUTHY_SECRET=xxxxxxxxxxxxxx] and another key PORT like [PORT=3000].

We can also change the subject to be dynamic and be passed through the body @v1b3m
