Grunt.js Watch Forever | 易学教程

问题

Goal:

I am trying to run a watch task in my Gruntfile.js as a daemon.

Normally, I would execute this script like: grunt watch.

Gruntfile.js:

module.exports = function(grunt) {

  grunt.initConfig({
    concat: {
      options: {
        separator: ''
      },
      dist: {
        src: ['static/js/**/*.js'],
        dest: 'app.js'
      }
    },
    watch: {
      files: ['<%= concat.dist.src %>'],
      tasks: ['concat']
    }
  });

  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-contrib-concat');
};

Question:

How do I spawn grunt watch as a daemon?

Update:

It appears as though considerations for this have already been made:

回答1:

you can use https://github.com/nodejitsu/forever exmaple

forever start gruntstart.js

gruntstart.js:

var exec = require('child_process').exec;

exec('grunt watch > log/grunt.log',
    function (error, stdout, stderr) {
        console.log('stdout: ' + stdout);
        console.log('stderr: ' + stderr);
        if (error !== null) {
           console.log('exec error: ' + error);
        }
});

回答2:

I'm a newbie in javascript, but I solved this problem with: tmux

One pane for simple operations like git and etc.
Other is for "grunt watch"

Even if I close the console tmux will go on with watching :D
