Presentation Transcript

  1. Grunt introduction

  2. The problem • Complexity • Growing number of assets • Increasing functionality • Technology • Code comments and code style • Code validation and unit tests • Portability (configure once and share) • Agile • Frequent deliveries

  3. The JavaScript Task Runner

  4. Ok, what can I do with Grunt? • LESS/SASS code compilation; • CSS or JavaScript files concatenation; • JavaScript minification; • JavaScript code check with JS Hint; • HTML and CSS code validation with w3c validators; • PHP code execution; • File operations (move/copy/delete/archive); • And aprrox. 2,265 more usecases

  5. Eh, that must be too complex to setup…I don’t have time!

  6. Setting-up Grunt project • Install Node.js • Install grunt-clinpminstall -g grunt-cli • Create package.json • Create Gruntfile.js • Use it by simply callinggrunt <task-name>

  7. package.json • { • "name": "my-project-name", • "version": "0.1.0", • "devDependencies": { • "grunt": "~0.4.2", • "grunt-contrib-jshint": "~0.6.3", • "grunt-contrib-nodeunit": "~0.2.0", • "grunt-contrib-uglify": "~0.2.2" • } • }

  8. Gruntfile.js • module.exports = function(grunt) { • // Project configuration. • grunt.initConfig({ • pkg: grunt.file.readJSON('package.json'), • uglify: { • /*** task config here ***/ • } • }); • // Load the plugin that provides the "uglify" task. • grunt.loadNpmTasks('grunt-contrib-uglify'); • // Default task(s). • grunt.registerTask('default', ['uglify']); • };

  9. Uglify task • uglify: { • options: { • banner: '/*! Our license data */\n' • }, • build: { • src: 'src/application.js', • dest: 'build/application.min.js' • } • }

  10. JS Hint task • jshint: { • src: [ • 'Gruntfile.js', • 'js/application.js', • ], • options: { • jquery: true, • globals: { • brightcove: true • } • } • }

  11. HTML validation task • 'html-validation': { • options: { • reset: true, • stoponerror: false, • relaxerror: [ • "Document uses the Unicode Private Use Area(.*)" • ], //ignores these errors, • }, • files: { • src: ['build/*.html'] • } • },

  12. Sequencing tasks • module.exports = function(grunt) { • // Project configuration. • grunt.initConfig(/* tasks config here */); • // Load the plugins that provides necessary tasks. • grunt.loadNpmTasks('grunt-contrib-uglify'); • // Default task(s). • grunt.registerTask('default', ['jshint','compass','copy','build','compress']) • }; • And then let the magic go • grunt
