grunt-openport v1.0.0

grunt-openport

A grunt plugin to find open ports.

Getting Started

Install this grunt plugin next to your project's Gruntfile.js gruntfile with: npm install grunt-openport

Then add this line to your project's Grunfile.js gruntfile:

grunt.loadNpmTasks('grunt-openport');

Documentation

This plugin provides 2 tasks: openport and openports.

• grunt openport
  Will set the first open port with grunt.config('port', port) in your Grunt config.
• grunt openport:env.val
  Will set the first open port with grunt.config('env.val', port) in your Grunt config.
• grunt openport:port:8000
  Will set the first open port on or above 8000 with grunt.config('port', port) in your Grunt config.
• grunt openport:port:9000:9010
  Will set the first open port between 9000 and 9010 with grunt.config('port', port) in your Grunt config.
• grunt openports:ports:2000:3000:4000:5000:6000
  Will find an open port from the given list of ports then set the array of open ports from the list with grunt.config('ports', ports) in your Grunt config.
• grunt openports:ports:2000:3000:4000:5000:6000:3
  Same as above but will only find the first 3 open ports.

Example

A common use case is determining which port to run a live reload server on with grunt-contrib-watch:

module.exports = function(grunt) {
  grunt.initConfig({
    watch: {
      options: {
        // Use the default port, 35729, at first
        livereload: true,
      },
      all: {
        files: ['src/*.js'],
        tasks: ['copy'],
      },
    },
  });
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-openport');
  grunt.registerTask('default', ['openport:watch.options.livereload:35729', 'watch']);
};

Now when grunt is ran and port 35729 is not available, it will start the live reload server on port 35730 instead (or the next open port).
