A grunt plugin that accepts a single line JavaScript file to be URI encoded and prepended with a protocol (eg, javascript:) for output.


grunt plugin to convert a JavaScript file to a URI, such as a javascript: bookmarklet or an iOS app protocol scheme link.

Version 1.3.0 begins grunt 0.4.0 compatibility and ends compatibility with earlier versions of grunt. Use [js2uri 1.2.0 ] if you require grunt 0.3.x compatibility.

Version 1.3.14 and above works with node 0.10.x - 0.12.x as the engine.

The code

alert("Hello. The current URL is: " + location.href);



Note that the "0" in void'0' can be used to embed a custom version number in a bookmarklet.

Install this grunt plugin next to your project's [Gruntfile.js gruntfile][getting_started] with: npm install js2uri --save. The --save options will add js2uri to the dependencies section of your project's [package.json] file.

Add the following to the grunt.initConfig section of your project's Gruntfile.js file:

js2uri:  {
  'dist/uriVersionOflintedAndMinifiedFile.js': ['dist/lintedAndMinifiedFile.js']

Edit the values for the dist/uriVersion... (destination) and dist/linted... (source) as appropriate.

Below the grunt.initConfig section, add this line to your project's Gruntfile.js.

// load external task 

Finally, ensure that jshint and uglify tasks are called before js2uri, such as here:

// default task 
grunt.registerTask('default', [ "jshint", "uglify", "js2uri"] );

An elaborated Gruntfile.js follows below to clarify expectations and options relating to js2uri. Note that as of js2uri v1.3.0 the [grunt] 0.4.x target data formats are supported for specifying files. See [gruntjs documentation - Configuring Tasks: files].

// if meta object exists js2uri will tempt to use version as options.customVersion value 
meta: {
  version: '1.6.1'
// note critical jshint options for strict, scripturl, & browser 
jshint: {
  files: ['Gruntfile.js', 'src/*.js'],
  options: {
  strict: false,
  scripturl: true,
  browser: true
  globals: {}
// note compact file spec-- 'destinationfile': ['sourcefile'], 
uglify: {
  'dist/lintedAndMinifiedFile.js': ['src/*.js'],
  options: {
    mangle: {toplevel: true},
    squeeze: {sequences: false, conditionals: false, hoist_vars: true},
    codegen: {quote_keys: false}
// js2uri default options are shown 
// note use of compact form of grunt 0.4.x files spec-- 'destinationfile': ['sourcefile'], 
js2uri:  {
  'dist/uriVersionOflintedAndMinifiedFile.js': ['dist/lintedAndMinifiedFile.js'],
  options: {
    protocol: 'javascript:',
    useNewlineEOL: true,
    useSingleQuote: true,
    appendVoid: true,
    customVersion: '', // use this if set, ELSE use version from meta above (if available) 
    appendVersion: false,
    noLastSemicolon: true,
    forceLastSemicolon: false,
    entityEncode: false
// Load "jshint" plugin 
// Load "uglify" plugin 
// Load "js2uri" plugin 
// Default task 
grunt.registerTask('default', [ "jshint", "uglify", "js2uri"] );

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