Grunt Simple Version

Easily update the version across your project. By default this updates the version field in package.json. Uses Semantic Versioning format.

Requirements

• Install Node JS
• Install Grunt npm install -g grunt-cli

Tasks Setup

Sample Gruntfile.js below. The version can take an optional map of file names as the options for files to update (other than package.json). For updating JSON files, the value is the name of the field to change. For instance, in this example bower.json has a field called version.

module.exports = function(grunt)
{
	grunt.loadNpmTasks('grunt-simple-version');

	grunt.initConfig({
		version: {
			options : {
				'bower.json' : 'version'
			}
		}
	});
};

Tasks Setup Examples

Nested-Field Update (JSON-only)

The target field property on a JSON file can also be nested using a dot-syntax style address. The example below would update a version field on a meta object.

grunt.initConfig({
	version : {
		options : {
			'info.json' : 'meta.version'
		}
	}
});

Cache-Busting Update (HTML-only)

Providing a value of cache-bust to an HTML file will append any src or CSS href properties with the version number. For instance, <script src="main.js"></script> would become <script src="main.js?v=1.0.0"></script>. This will help invalid the browser cache for linked assets.

grunt.initConfig({
	version : {
		options : {
			'deploy/index.html' : 'cache-bust'
		}
	}
});

Replacement Update

A replacement function can be used to replace the version in the contents of a file. The function takes two arguments, the contents of the file and the version number to update to. The function must return an update string with the contents of the file.

grunt.initConfig({
	version : {
		options : {
			'deploy/index.html' : function(content, version) {
				return content.replace(
					/\<\!\-\- Version .* \-\-\>/,
					'<!-- Version ' + version + ' -->'
				);
			}
		}
	}
});

Multiple Updates

The target field also supports multiple options (fields, nested-fields, functions, cache-bust) for a single file. The example below would update two fields in the JSON file with the version and do a dynamic function replacement.

grunt.initConfig({
	version : {
		options : {
			'project.json' : [
				'version', 
				'meta.version', 
				function(content, version){
					content.description = "Current build version " + version;			
				}
			]
		}
	}
});

Usage

Ways to set the version across the project:

# Return the current version
grunt version:current

# Set a specific version
grunt version:1.0.0-rc

# Bump the patch version e.g., 1.0.1 => 1.0.2
grunt version:patch

# Bump the patch version e.g., 1.2.1 => 1.3.0
grunt version:minor

# Bump the patch version e.g., 1.3.0 => 2.0.0
grunt version:major
