uest

req.uest is an Express middleware that allows you, from a given route, to request another route.

Features are:

• Initial req cookies are passed along to subsequent req.uests
• Cookies set by req.uests responses are forwarded to res
• req.session stay in sync between requests

It allows you to decouple your app's routes from your API's ones. IOW, your app routes can now consume your API as any client.

Install

$ npm i uest

// app.js

const uest = require('uest')

app.use(uest())

Usage

req.uest(options, (er, resp, body) => {})

• options -- are the same as request/request, with defaults to json: true and baseUrl to the same as your Express server.
• resp -- the response object, see: http.IncomingMessage
  • resp.body holds the JSON response datas
• er -- when an error occurs or resp.statusCode >= 400, see: http.ClientRequest
  • er.status holds the response statusCode, for example: 404 or 409...

Example

// Mount our API router
app.use('/api', require('./routers/api'));

//
// App routing
//

app.post('/login', (req, res, next) => {
  const {email, password} = req.body

  //
  // Our subsequent request to `POST /api/sessions` route
  //

  req.uest({
    method: 'POST',
    url: '/api/sessions',
    body: {email, password}
  }, (er, resp, body) => {
    if (er) {
      // Deal with specific "Forbidden" error
      if (er.status === 403) {
        return res.render('login', {error: "Wrong login/password"})
      }

      return next(er); // for any other error
    }

    console.log('User-session created for', body.user)

    // `req.session` is up-to-date
    console.log(`Welcome back ${req.session.user.firstname}!`
      
    res.redirect('/profile')
  })
});
