express-http-proxy

Express proxy middleware to forward request to another host and pass response back

Install

$ npm install express-http-proxy --save

Usage

var proxy = require('express-http-proxy');

var app = require('express')();

app.use('/proxy', proxy('www.google.com', {
  forwardPath: function(req, res) {
    return require('url').parse(req.url).path;
  }
}));

If you only want to proxy get request

app.use('/proxy', proxy('www.google.com', {
  filter: function(req, res) {
     return req.method == 'GET';
  },
  forwardPath: function(req, res) {
    return require('url').parse(req.url).path;
  }
}));

You can also intercept the response get by proxy before send it back to the client:

app.use('/proxy', proxy('www.google.com', {
  forwardPath: function(req, res) {
    return require('url').parse(req.url).path;
  },
  intercept: function(data, req, res, callback) {
       data = JSON.parse(data.toString('utf8'));
       callback(null, JSON.stringify(data.obj));
  }
}));
