response-distort v1.0.0

response-distort

Hooks into an http.ServerResponse instance to modify its response body.

Useful, for example, to inject JavaScript into an HTML response.

Usage

distort(res, map(body, done))

Accepts res, an instance of http.ServerResponse, and map, a callback that's called when the response is ready to be modified.

map's first argument is the original response body. You should call done(null, modifiedBody) with the updated response body when you're ready to do so.

const distort = require('response-distort')
const http    = require('http')

http.createServer(function(req, res) {
  distort(res, function(body, done) {
    done(null, body.toUpperCase())
  })

  // handle the response as normal...
}).listen(function() {
  // ...
})
