Package Exports

express-http-proxy

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (express-http-proxy) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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 before sending it back to the client, or change the request options before it is sent to the target:

app.use('/proxy', proxy('www.google.com', {
  forwardPath: function(req, res) {
    return require('url').parse(req.url).path;
  },
  intercept: function(rsp, data, req, res, callback) {
       // rsp - original response from the target
       data = JSON.parse(data.toString('utf8'));
       callback(null, JSON.stringify(data));
  },
  decorateRequest: function(req) {
       req.headers['Content-Type'] = '';
       req.method = 'GET';
       req.bodyContent = wrap(req.bodyContent);
       return req;
  }
}));
