grunt-dojo2

A package of Grunt tasks and configuration to use with Dojo 2 Packages.

Installation

This package contains configuration and tasks for Grunt to help orchestrate development of Dojo 2 Packages. It is meant to be a development dependency of a Dojo 2 package.

To install:

$ npm install grunt-dojo2 --save-dev

The package Gruntfile.js should look like this:

module.exports = function (grunt) {
	require('grunt-dojo2').initConfig(grunt);
};

Code Style

This repository uses prettier for code styling rules and formatting. A pre-commit hook is installed automatically and configured to run prettier against all staged files as per the configuration in the projects package.json.

An additional npm script to run prettier (with write set to true) against all src and test project files is available by running:

npm run prettier

Dependencies

There are several peer dependencies which you should have installed in the containing project:

Configuration

If you need to customise the Grunt configuration, you can do so by passing a second argument to the initConfig() function. For example to configure Uglify2, you would do something like this:

module.exports = function (grunt) {
	grunt.loadNpmTasks('grunt-contrib-uglify');

	require('grunt-dojo2').initConfig(grunt, {
		uglify: {
			dist: {
				options: {
					sourceMap: true,
					sourceMapName: 'dist/umd/_debug/module.min.js.map',
					sourceMapIncludeSources: true,
					sourceMapIn: 'dist/umd/_debug/module.js.map',
					compress: {
						dead_code: true,
						unsafe: true
					}
				},
				files: {
					'dist/umd/module.min.js': 'dist/umd/module.js'
				}
			}
		}
	});

	grunt.registerTask('dist', grunt.config.get('distTasks').concat('uglify:dist'));
};

Tasks

grunt tslint

The grunt tslint task, runs tslint with the following configuration.

options: {
	configuration: grunt.file.readJSON('tslint.json')
},
src: {
	src: [
		'<%= all %>',
		'!typings/**/*.ts',
		'!tests/typings/**/*.ts',
		'!node_modules/**/*.ts'
	]
}

grunt dojo-ts

The grunt dojo-ts task runs a project through the TypeScript compiler using the project's tsconfig.json. It is preconfigured with two targets, dev and dist.

dev

The dev target transpiles a project for development. src/ and test/ files are built and the output is put in the _build directory.

dist

The dist target prepares a project for distribution and applies the following overrides to the tsconfig:

{
	compilerOptions: {
		outDir: distDirectory,
		declaration: true
	},
	exclude: ['tests/**/*.ts']
}

Where the distDirectory is defaulted to dist/umd.

If you have other root level directories besides src and tests, you might want to exclude them from the dist build. Including them can cause unwanted output in your dist/umd directory. For example, if you wanted to exclude an examples directory, you would add:

ts: {
	dist: {
		exclude: ['tests/**/*.ts', 'examples/**/*.ts'],
	}
}

Custom Targets

It is possible to create custom targets for the ts by adding an entry to the grunt config, such as:

"ts": {
	"custom": {
		"compilerOptions": {
			"target": "es6",
			"module": "commonjs"
		}
	}
}

The custom ts config can be run using grunt grunt-ts:custom.

grunt intern

The intern task provides multiple preconfigured targets

options: {
	runType: 'runner',
	config: '<%= devDirectory %>/tests/intern',
	reporters: [ 'Runner' ]
},
browserstack: {},
	saucelabs: {
		options: {
			config: '<%= devDirectory %>/tests/intern-saucelabs'
		}
	},
remote: {},
local: {
	options: {
		config: '<%= devDirectory %>/tests/intern-local',
	}
},
node: {
	options: {
		runType: 'client'
	}
},
proxy: {
	options: {
		proxyOnly: true
	}
}

grunt doc

The doc task is used to automatically build and publish API documentation to the project's GitHub pages. Please note that if you want to generate documentation locally by manually running this command use the grunt typedoc command instead.

Environment Variables

Running grunt typedoc (part of grunt doc) will only generate APIs using typedoc. In order to automatically commit or publish API documentation the DEPLOY_DOCS environment variable must be set to either publish or commit. Environment variables are used so they may be turned on/off using travis-ci settings and to support forks that may want to use the travis build, but do not want to automatically publish documentation.

Prerequisites

To support continuous delivery of API documents to your project's GitHub pages Travis-ci needs access to your GitHub repository. This is best achieved by supplying an encrypted deployment key that can be used via SSH (there are other methods that are less secure that we will not go into). To use this method you will need to:

1. Create a ssh key; e.g. ssh-keygen -t rsa -C "your_email@example.com"
2. encrypt the private key using travis cli; e.g. travis encrypt-file deploy_key (you will need to be logged in and be the owner of the GitHub repository to do this)
3. add the public key under your project's GitHub settings
4. add grunt doc --publish-api as part of your install steps

grunt link

The link task is designed to ease the local development and testing of changes that span multiple packages. Traditionally npm link can be used but this assumes that the project structure is the same as the distribution, which for dojo2 projects is not the case.

This command emulates the behaviour of npm link but with some additional steps to ensure that the linked structure matches that of the distributed package.

Once grunt link has been run within a dojo2 package, npm link can be used as normal to created the linked package dependency.

Example

npm link dojo-widgets

grunt release

The release task automates all the steps involved in building, tagging and publishing a dojo2 package.

grunt release --pre-release-tag=alpha

note:

1. Task runs the dist pipelines as a prerequisite.
2. Requires being logged into NPM unless using the dry-run options

#####Options

The pre-release-tag is required, the other options are all optional.

• pre-release-tag- determines the pre-release tag used for the published version (usually alpha, beta or rc)
• dry-run - performs the release in dry run mode, no commits, tags or publishing occur. The generated package is built into the dist directory.
• initial - indicates that it is an initial release of an asset and therefore assumes the version rather than using npm veiw.
• skip-checks - skips checks against the registered maintainers, only available with dry-run
• push-back - automatically pushes back to github (tags and commits)
• tag - the npm tag to publish as (defaults to next)

• clean:typings
• typings
• tslint

• clean:ghpages

test

The running grunt test will execute the test pipeline which as follows:

• clean:coverage
