Connect or Express middleware to modify the response.body

Question

I would like to have a middleware function which modifies the response body.

This is for an express server.

Something like:

function modify(         


        

Answer 1

express-mung is designed for this. Instead of events its just more middleware. Your example would look something like

const mung = require('express-mung')

module.exports = mung.json(body => body.modifiedBy = 'me');
