Start proxy server


Start proxy server using http-proxy.

If you haven't used grunt before, be sure to check out the Getting Started guide.

From the same directory as your project's Gruntfile and package.json, install this plugin with the following command:

npm install grunt-proxy --save-dev

Once that's done, add this line to your project's Gruntfile:


If the plugin has been installed correctly, running grunt --help at the command line should list the newly-installed plugin's task or tasks. In addition, the plugin should be listed in package.json as a devDependency, which ensures that it will be installed whenever the npm install command is run.

In your project's Gruntfile, add a section named proxy to the data object passed into grunt.initConfig().

  proxy: {
    proxy1 : {
        options : {
            port : 8050,            // start proxy server, listening to the port 8050 
            host : 'localhost',         // bind proxy server to 'localhost' interface 
            target : {              // make it forward all the requests to localhost:8011 
                host: 'localhost',
                port: 8011
    proxy2 : {
        options : { // start proxy server, listening to the default port 9000 
            router : {      // make it forward requests according to this table 
                'localhost/secure'    : '',
                'localhost/insecure/' : ''
            https  : {
                key   : fs.readFileSync( path.join(proxyKeysDir, 'server.key'), 'utf8' ),
                cert  : fs.readFileSync( path.join(proxyKeysDir, 'server.crt'), 'utf8' )
            changeOrigin : true

The simple rule is: all options except for options.port and are passed to http-proxy's proxy.createServer(options) method. The options.port and are removed from options and are passed to the server's server.listen(port, host) method.

Type: Integer Default value: 9000

A port number to which the proxy server should listen to.

Type: String Default value: none

An optional hostname at which the proxy accepts connections.

All options except for the abovementioned are passed to http-proxy's proxy.createServer(options) method. Please refer to http-proxy documentation.

Note, if options.router is given, is ignored.

See overview section above and tests

grunt test

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
