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 🙏

Readme

grunt-tmplt

Share values between different file types.

Getting Started

This plugin requires Grunt ~0.4.5

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, you may install this plugin with this command:

npm install grunt-tmplt --save-dev

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

grunt.loadNpmTasks('grunt-tmplt');

The "tmplt" task

Overview

Run this task with the grunt tmplt command. The src property will use the Grunt glob pattern to specify files that should be included.

In your project's Gruntfile, add a section named tmplt to the data object passed into grunt.initConfig().

grunt.initConfig({
  tmplt: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
      src: []
    },
  },
});

Options

options.ext

Type: String Default value: 'tmplt'

File extension that is used to find your template files. To template a javascript file you'll then name it nameOfJavascriptFile.tmplt.js, a less file nameOfLessFile.tmplt.less and so on.

options.tmpltsrc

Type: String Default value: '.tmpltsrc.json'

JSON source file for your templating data

files

files.src

Grunt glob pattern to specify files that should be included

files.flatten

Type: Boolean Default value: false

files.dest

Usage Examples

Setup in grunt

...

  tmplt: {
  	colors: {
    	options: {
    		//template data for any file specified in src
      		tmpltsrc: "globals/colours.json"
    	},
    	files: {
    		//will run tmplt on any *.tmplt.less and *.tmplt.js in the assets folder
    		src: ["assets/**/*.less", "assets/**/.js"],
    		flatten: true, //Remove all path parts from generated dest paths.
    		dest: 'build/' // Destination path prefix.
    	}
  	}
  },
...

Store the data you want to share between files in colours.json

{
	"colorPrimary": "#222",
	"colorSecondary": "#fff"
}

Use the data in a javascript file name a file nameOfJavascriptFile.tmplt.js

...

var colorPrimary = "<%= colorPrimary %>";
var colorSecondary = "<%= colorSecondary %>";

...

and then in a less file called nameOfLessFile.tmplt.less

...

.button{
	color: <%= colorPrimary %>;
	background-color: <%= colorSecondary %>;
}
...

Running the tmplt task will then create a javascript file called nameOfJavascriptFile.js

...

var colorPrimary = "#222";
var colorSecondary = "#fff";

...

and a less file nameOfLessFile.less

...

.button{
	color: #222;
	background-color: #fff;
}
...

###Use with watch

It makes sense to use the tmplt task togheter with a watch task. The setup for using tmplt with grunt-contrib-watch could look something like this:

...

watch: {
    configFiles: {
        files: {
            src: ['Gruntfile.js']
        },
        options: {
            reload: true,
            spawn: true
        }
    },
    less: {
        files: {
            src: ['**/*.less', '!**/*.tmplt.less']
        },
        tasks: ['less'],
        options: {
            livereload: true
        }
    },
    js: {
        files: {
            src: ['assets/scripts/*.js', '!**/*.tmplt.js']
        },
        options: {
            livereload: true
        }
    },            
    tmpltLess: {
        files: {
            src: ['assets/styles/**/*.tmplt.less', "globals/**/*.json"]
        },
        tasks: ['tmplt']
    },
    tmpltJs: {
        files: {
            src: ['assets/scripts/*.tmplt.js', "globals/**/*.json"]
        },
        tasks: ['tmplt'] 
    }                        
},

...

Any changes to the data in the json file or a template file now will generate the js and less files automatically.
