req.set() 📌

Set request headers like response headers in Express

Compatible with any node version running Express

Why does this matter?

Updating request headers directly in express isn't supported in the same manner as res.set()

For example, you lose the ability to fetch those headers in a case-insensitive manner such as with req.get()

req.headers['Content-Type'] = 'application/json';
req.get('content-type') // => undefined

Usage

It uses the same API as res.set()

var reqSet = require('req.set');
 
app.use((req, res, next) => {
  // extend req
  reqSet.extend(req);
 
  // object api
  req.set({
    'foo': 1,
    'Bar': 2
  });
 
  // string api
  req.set('baz', 100);
 
  // Compatible with req.get(), case-insensitive
  req.get('foo'); // => 1
  req.get('bar'); // => 2
  req.get('baz'); // => 100
 
  // Calls the origina req.get() under the API, so built-in express helpers work
  req.get('referer')  // => github.com
  req.get('Referer')  // => github.com
  req.get('referrer') // => github.com
  req.get('Referrer') // => github.com
});
// If an object is passed, it will be stringified
 
req.set('object', { complex: true });
req.get('object') // => '{"complex":true}'

There's also a middleware for one-time application use so each request is extended with .set()

var reqSet = require('req.set');
app.use(reqSet.middleware);
