For those times when javascripts need to be dynamically created at build time!


For those times when javascripts have to be dynamically created at build time! shave uses Mustache and Config to pre-compile source code that have placeholders that have to be replaced at build-time (e.g., database configuration code)

var db = new Db("mydb", new Server("", 27017,
 {auto_reconnect: false, poolSize: 4}), {safe:false, native_parser: false});

Which can be replaced with

var db = new Db("{{db_name}}", new Server("{{server_name}}", 27017,
 {auto_reconnect: false, poolSize: 4}), {safe:false, native_parser: false});

and a settings yaml file inside config/default.yml such as

  server_name: "localhost"
  db_name: "mydb"

This plugin requires Grunt ~0.4.1, Mustache ~0.7.2 and Config : ~0.4.25,

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-shave --save-dev

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


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

  shave: {
    options: {key1: val1, key2: val2}, // This is the hash passed to mustache for replacements (key1 will be replaced by val1 etc.) 
    src: "js/all_in_one.js", // The source file that you want transformed (after replacing placeholders) 
    dest: "js/after_transformation.js" // this is where the transformed file (after placeholders are replaced) will be placed. 

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
