grunt-connect-proxy

grunt-connect-proxy

Provides an http proxy as middleware for the grunt-contrib-connect plugin.

Getting Started

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-connect-proxy --save-dev

One the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-connect-proxy');

Adapting the "connect" task

Overview

Proxy Configuration

In your project's Gruntfile, add a section named proxies to your existing connect definition.

grunt.initConfig({
    connect: {
            options: {
                port: 9000,
                hostname: 'localhost'
            },
            proxies: [
                {
                    context: '/cortex',
                    host: '10.10.2.202',
                    port: 8080,
                    https: false,
                    changeOrigin: false
                }
            ]
        }
})

Adding the middleware Expose the proxy function to use in the middleware, at the top of the grunt file:

var proxySnippet = require('grunt-connect-proxy/lib/utils').proxyRequest;

Add the middleware call from the connect option middleware hook

        connect: {
            livereload: {
                options: {
                    middleware: function (connect) {
                        return [
                            proxySnippet
                        ];
                    }
                }
            }
        }

Adding the configureProxy task to the server task

For the server task, add the configureProxies task before the connect task

    grunt.registerTask('server', function (target) {
        grunt.task.run([
            'clean:server',
            'compass:server',
            'configureProxies',
            'livereload-start',
            'connect:livereload',
            'open',
            'watch'
        ]);
    });

Options

The available configuration options from a given proxy are generally the same as what is provided by the underlying httpproxy library

options.context

Type: String

The context to match requests against. Matching requests will be proxied. Should start with /. Should not end with /

options.host

Type: String

The host to proxy to. Should not start with the http/https protocol.

options.port

Type: Number Default: 80

The port to proxy to.

options.https

Type: Boolean Default: false

Whether to proxy with https

options.changeOrigin

Type: Boolean Default: false

Whether to change the origin on the request to the proxy, or keep the original origin.

options.appendProxies

Type: Boolean Default: true

Set to false to isolate multi-task configuration proxy options from parent level instead of appending them.

Contributing

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.

Multi-server proxy configuration

grunt-contrib-connect multi-server configuration is supported. You can define proxies blocks in per-server options and refer to those blocks in task invocation.

grunt.initConfig({
    connect: {
            options: {
                port: 9000,
                hostname: 'localhost'
            },
            server2: {
                proxies: [
                    {
                        context: '/cortex',
                        host: '10.10.2.202',
                        port: 8080,
                        https: false,
                        changeOrigin: false
                    }
                ]
            },
            server3: {
                appendProxies: false,
                proxies: [
                    {
                        context: '/api',
                        host: 'example.org'
                    }
                ]
            }
        }
})

grunt.registerTask('e2etest', function (target) {
    grunt.task.run([
        'configureProxies:server2',
        'open',
        'karma'
    ]);
});
