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-Template-Coffee

NPM Version Build Status Dependency Status Built with Grunt

Grunt-init scaffolding template for CoffeeScript applications with support for CoffeeLint, Mocha & Should.js, UglifyJS and Codo via Grunt tasks

If you are new to using templates with Grunt, take a look at Grunt-Init.

Installation

Prerequisites

This template uses Grunt-Init to transform a template into an actual project and CoffeeLint to lint the CoffeeScript files - you must have it installed and globally available, including one CoffeeLint plugin which provides additional linting check:

[sudo] npm install -g coffeelint coffeelint-newline-at-eof

Installing the template

This package is available in the NPM Registry, so you can install it via npm:

npm install grunt-template-coffee

Once installed, you may wish to move the template to your $HOME directory to make the template available from anywhere:

mv ./node_modules/grunt-template-coffee ~/.grunt-init/node-coffee

Note that while installation by cloning this repository is also possible, NPM contains a pre-compiled version of the template, so you don't have to grunt build it yourself.

Usage

Once the template is installed in your $HOME, all you have to do is create a folder with the name of the project you are about to start and run the grunt-init command:

mkdir My-Awesome-Project # Create a clean folder for your new project
grunt-init node-coffee
# ... You answering questions, Grunt doing its magic...
npm install # Install development dependencies

The node-coffee is the actual name of this template. You can customise its name by renaming the folder where you installed it ( in the ~/.grunt-init folder ).

Specifying default answers

If you find yourself overriding the automatically-detected default answers each time you bootstrap a new project, you may wish to create a defaults.json file to provide your own defaults. Read more on official Grunt-Init's webpage.

What's included?

The following tasks are at your disposal in the template:

  1. lint - Lint your CoffeeScript files using CoffeeLint
  2. test - Test your CoffeeScript using Mocha and Should.js
  3. build - Lint your code, test it, compile your CoffeeScript files, move them into place and then uglify them, making the app ready for publishing to NPM
  4. docs - Generate API documentation from your source code using Codo

Core concepts

Applications written in CoffeeScript are awesome, but CS should never be used in production - compilation on-the-fly takes precious CPU cycles away while your app might have been doing something much more useful. It also makes more sense to compile ahead of time as it gives you precise control over the way it is going to be compiled, thus preventing possible future issues when new versions of CoffeeScript are released ( such as when the Coffee-Script-Redux project is eventually merged into the main CS project ).

In addition to providing a means to compile CoffeeScript ahead of time, this template provides several project structure concepts that should keep your folder and file structure clean as much as possible.

Project folder structure

Let's discuss how the project is organised.

$ My-Awesome-Project  --> root folder of your project
.
├── src/              --> CoffeeScript source files
├── res/              --> Static content - images, text files etc.
├── test/             --> Your test cases
│
├── gruntfile.coffee  --> Grunt tasks configuration
├── index.coffee      --> Your application's entry point
├── package.json      --> NPM's package description
├── coffeelint.json   --> CoffeeLint's linting rules
├── .travis.yml       --> (optional) Travis configuration
├── .gitignore
├── README.md         --> Your README file
└── LICENSE           --> The license text being used

The src folder:

Your CoffeeScript files should be stored here. You may organise your project inside this folder however you wish; your folder structure will be preserved once you build your app.

The res folder:

Static content like images, text files, or any other non-CoffeeScript files should be placed here. All these files will be simply copied over to the staging area upon build.

The test folder:

Write your test suites here. Mocha is used as testing framework, while Should.js provides the assertions for your tests.

The build process:

Build your application with the grunt build command - it will:

  1. Compile CoffeeScript in src/ to JavaScript and place the compiled files next to your source code
  2. Compile your index.coffee to JavaScript
  3. Do nothing with files inside the res/ folder
  4. Uglify and mangle all compiled JavaScript files

When finished, you will have an optimised version of your project, ready for publishing to NPM. Just give it a try - create a test project, install dependencies and run grunt build, then take a look around to see what happened.

Publishing to NPM Registry:

Once you have everything sorted out and your application built successfully, simply publish your application to NPM via npm publish. And, you are done!

The template also installs some sample content to show you how to write and organise the code so you get better understanding about your possibilities.

Creating additional directories

If you would like to give your code more structure via folder hierarchy, always remember to create a .gitignore file in all new folders that excludes all *.js files ( to prevent accidentally commiting compiled JavaScript code into your repository ) and also update the .npmignore file in the root directory to exclude all YOUR_FOLDER/*.coffee files to prevent publishing your source CoffeeScript files with your optimised content.

Planned features

I am not quite happy with the whole package release workflow as it stands now ( bump version, commit to develop, merge develop to master, tag the commit, push to GitHub, push to NPM ) so I will be looking into providing a simple, configurable task to do all this heavy lifting, possibly also generating documentation and pushing it to gh-pages.

Generating the API documentation is optional: grunt docs will generate the html content in lib/docs/ folder.
