Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

grunt-fast-watch

similar to grunt-contrib-watch, but faster.

Why Another Watch?

grunt-contrib-watch somtime didn't capture fs event (in windows). And, it too slow for my purpose.

I using fast-watch to restart server for reloading source code in development.

I am impatience, so made this.

Features

  • fast, fast, fast!
  • surely capture fs event in windows.
  • watch dir, not file
  • support ignore setting(git ignore style, visit ignore)
  • call different task by file path matching
  • didn't unwatch when call tasks
  • after running tasks, restart fastWatch task ( without redundant watch )

Getting Started

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 --save-dev grunt-fast-watch

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

grunt.loadNpmTasks('grunt-fast-watch');

Tip: the load-grunt-tasks module makes it easier to load multiple grunt tasks.

Examples

 
trim = (str)->
  str.replace /(^\s*)|(\s*$)/gm, ""
fromLines = (patterns)->
  return trim(patterns).split('\n').map (pattern)->
    trim(pattern)


ignoreDir = fromLines """ 
.git
.gitignore
tmp        
node_modules

"""
serverCares = fromLines """
*.coffee       
*.json
""" 

clientCares = fromLines """ 
*.coffee   
!Gruntfile.coffee
package.json 
"""  # every coffee file, but Gruntfile.coffe + package.json
 
module.exports = (grunt)->   
 
  grunt.initConfig 
    fastWatch:
      cwd:     
        dir : '.' 
        ignoreSubDir : ignoreDir 
        trigger:
          server:  
            care : serverCares
            tasks: ["print:Server"]
          client: 
            care : clientCares  
            tasks: ['print:Client']

  grunt.loadTasks 'tasks' 

  grunt.registerTask 'print', (arg)-> console.log 'PRINT ',arg
  grunt.registerTask 'default', 'fastWatch:cwd'

   

Watch all event under dir ( . = current workign directory ) exclude sub-direcoty matched by .ignoreSubDir

When file system event wached, it test trigger.*.care

If passed, run tasks.

Configuration

dir & ignoreSubDir designate dirs which are watched.

trigger contains tasks list which are called by care

See ignore for ignoreSubDir and care

one more thing, matching of care is reverse result of ignore

Put simply, ignore module filter out changed file path, then watcher cares. And vice versa.

It may be seem weird, but [ignore]]ig is just filepath filter.

Anyway, write pattern naturally then fast-watch understands.
