grunt-contrib-connect
Advanced tools
grunt-contrib-connect is a Grunt plugin that provides a simple web server for serving static files. It is commonly used in development workflows to serve files, enable live reloading, and proxy requests to other servers.
Serve Static Files
This feature allows you to serve static files from a specified directory. In this example, the server runs on port 9000 and serves files from the 'public' directory.
json
{
"connect": {
"server": {
"options": {
"port": 9000,
"base": "public"
}
}
}
}
Live Reload
This feature enables live reloading of the web page when files change. The server is configured to use live reload, and the watch task monitors changes in the 'public' directory.
json
{
"connect": {
"server": {
"options": {
"port": 9000,
"base": "public",
"livereload": true
}
}
},
"watch": {
"options": {
"livereload": true
},
"files": [
"public/**/*"
]
}
}
Proxy Requests
This feature allows you to proxy requests to another server. In this example, requests to '/api' are proxied to 'api.example.com' on port 80.
json
{
"connect": {
"server": {
"options": {
"port": 9000,
"base": "public",
"middleware": function(connect, options, middlewares) {
middlewares.unshift(require('grunt-connect-proxy/lib/utils').proxyRequest);
return middlewares;
}
},
"proxies": [
{
"context": "/api",
"host": "api.example.com",
"port": 80
}
]
}
}
}
http-server is a simple, zero-configuration command-line HTTP server. It is similar to grunt-contrib-connect in that it serves static files, but it is a standalone tool and does not require Grunt.
live-server is a simple development HTTP server with live reload capability. It is similar to grunt-contrib-connect's live reload feature but is a standalone tool that does not require Grunt.
browser-sync is a powerful tool for synchronizing browser testing. It provides live reloading, CSS injection, and synchronized browser testing. It offers more features compared to grunt-contrib-connect but can be used alongside Grunt.
Start a connect web server.
Note that this plugin has not yet been released, and only works with the latest bleeding-edge, in-development version of grunt. See the When will I be able to use in-development feature 'X'? FAQ entry for more information.
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, install this plugin with this command:
npm install grunt-contrib-connect --save-dev
Run this task with the grunt connect command.
This task is a [multi task][] so any targets, files and options should be specified according to the [multi task][] documentation. [multi task]: https://github.com/gruntjs/grunt/wiki/Configuring-tasks
Note that this server only runs as long as grunt is running. Once grunt's tasks have completed, the web server stops. This behavior can be changed with the keepalive option, and can be enabled ad-hoc by running the task like grunt connect:keepalive.
This task was designed to be used in conjunction with another task that is run immediately afterwards, like the grunt-contrib-qunit plugin qunit task.
This plugin is only compatible with Grunt >= 0.4.0. This plugin is the replacement for the Grunt v0.3 core task server.
Type: Integer
Default: 8000
The port on which the webserver will respond. The task will fail if the specified port is already in use.
Type: String
Default: 'localhost'
The hostname the webserver will use.
Type: String
Default: '.'
The base (or root) directory from which files will be served. Defaults to the project Gruntfile's directory.
Type: Boolean
Default: false
Keep the server alive indefinitely. Note that if this option is enabled, any tasks specified after this task will never run. By default, once grunt's tasks have completed, the web server stops. This option changes that behavior.
This option can also be enabled ad-hoc by running the task like grunt connect:targetname:keepalive
Type: Function
Default:
function(connect, options) {
return [
// Serve static files.
connect.static(options.base),
// Make empty directories browsable.
connect.directory(options.base),
];
}
Lets you add in your own Connect middlewares. This option expects a function that returns an array of middlewares. See the project Gruntfile and project unit tests for a usage example.
In this example, grunt connect (or more verbosely, grunt connect:server) will start a static web server at http://localhost:9001/, with its base path set to the www-root directory relative to the gruntfile, and any tasks run afterwards will be able to access it.
// Project configuration.
grunt.initConfig({
connect: {
server: {
options: {
port: 9001,
base: 'www-root'
}
}
}
});
If you want your web server to use the default options, just omit the options object. You still need to specify a target (uses_defaults in this example), but the target's configuration object can otherwise be empty or nonexistent. In this example, grunt connect (or more verbosely, grunt connect:uses_defaults) will start a static web server using the default options.
// Project configuration.
grunt.initConfig({
connect: {
uses_defaults: {}
}
});
You can specify multiple servers to be run alone or simultaneously by creating a target for each server. In this example, running either grunt connect:site1 or grunt connect:site2 will start the appropriate web server, but running grunt connect will run both. Note that any server for which the keepalive option is specified will prevent any task or target from running after it.
// Project configuration.
grunt.initConfig({
connect: {
site1: {
options: {
port: 9000,
base: 'www-roots/site1'
}
},
site2: {
options: {
port: 9001,
base: 'www-roots/site2'
}
}
}
});
Like the Basic Use example, this example will start a static web server at http://localhost:9001/, with its base path set to the www-root directory relative to the gruntfile. Unlike the other example, this is done by creating a brand new task. in fact, this plugin isn't even installed!
// Project configuration.
grunt.initConfig({ /* Nothing needed here! */ });
// After running "npm install connect --save-dev" to add connect as a dev
// dependency of your project, you can require it in your gruntfile with:
var connect = require('connect');
// Now you can define a "connect" task that starts a webserver, using the
// connect lib, with whatever options and configuration you need:
grunt.registerTask('connect', 'Start a custom static web server.', function() {
grunt.log.writeln('Starting static web server in "www-root" on port 9001.');
connect(connect.static('www-root')).listen(9001);
});
