API

server.run([args][,options][,livereload])

Run/re-run the script file, which will create a http(s) server.

Start a livereload(tiny-lr) server if it's not started yet.

Use the same arguments with ChildProcess.spawn with 'node' as command.

• args - Array - Array List of string arguments. The default value is ['app.js'].
• options - Object - The third parameter for ChildProcess.spawn, the default value is:

options = {
    cwd: undefined
}
options.env = process.env;
options.env.NODE_ENV = 'development';

• livereload - Boolean|Number|Object - The option for tiny-lr server. The default value is 35729.
  • false - will disable tiny-lr livereload server.
  • number - treated as port number of livereload server.
  • object - used to create tiny-lr server new tinylr.Server(livereload);.
• Returns a ChildProcess instance of spawned server.

server.stop()

Stop the instantiated spawned server programmatically, and the tiny-lr server.

server.notify([event])

Send a notification to the tiny-lr server in order to trigger a reload on page. pipe support is added after v0.1.5, so you can also do this:

gulp.src('css/*.css')
// …
.pipe(gulp.dest('public/css/'))
.pipe(server.notify())

• event (required when server.notify is invoked without pipe) - Object - Event object that is normally passed to gulp.watch callback. Should contain path property with changed file path.

Usage

// gulpfile.js
var gulp = require('gulp');
var server = require('gulp-express');

gulp.task('server', function () {
    // Start the server at the beginning of the task
    server.run(['app.js']);

    // Restart the server when file changes
    gulp.watch(['app/**/*.html'], server.notify);
    gulp.watch(['app/styles/**/*.scss'], ['styles:scss']);
    //gulp.watch(['{.tmp,app}/styles/**/*.css'], ['styles:css', server.notify]);
    //Event object won't pass down to gulp.watch's callback if there's more than one of them.
    //So the correct way to use server.notify is as following:
    gulp.watch(['{.tmp,app}/styles/**/*.css'], function(event){
        gulp.run('styles:css');
        server.notify(event);
        //pipe support is added for server.notify since v0.1.5,
        //see https://github.com/gimm/gulp-express#servernotifyevent
    });

    gulp.watch(['app/scripts/**/*.js'], ['jshint']);
    gulp.watch(['app/images/**/*'], server.notify);
    gulp.watch(['app.js', 'routes/**/*.js'], [server.run]);
});

// app.js
var express = require('express');
var app = module.exports.app = exports.app = express();

//you won't need 'connect-livereload' if you have livereload plugin for your browser
app.use(require('connect-livereload')());
