Calling Express Route internally from inside NodeJS

Question

I have an ExpressJS routing for my API and I want to call it from within NodeJS

var api = require(\'./routes/api\')
app.use(\'/api\', api);

Answer 1

This is an easy way to do an internal redirect in Express 4:

The function that magic can do is: app._router.handle()

Testing: We make a request to home "/" and redirect it to otherPath "/other/path"

var app = express()

function otherPath(req, res, next) {
  return res.send('ok')
}

function home(req, res, next) {
  req.url = '/other/path'
  /* Uncomment the next line if you want to change the method */
  // req.method = 'POST'
  return app._router.handle(req, res, next)
}

app.get('/other/path', otherPath)
app.get('/', home)
