Angular Music Database

One-page Web Application Built With AngularJS,TypeScript,and Yii framework.

Overview

This application demonstrates a one page web application where all the logic has been moved to the frontend.The page loads only once.The backend (Yii) serves JSON data and the frontend consumes it as it renders partial views,which have been baked into the concatenated and minified javascript.To demonstrate Create/Read/Update/Delete features a Music Database is set up with Artists,Albums,and Tracks information.The application features deep linking:when you refresh the page at any location,the application reloads and lands at the same location.Modern frontend tools like Grunt are used to showcase their effectiveness in development workflow.Tests (unit/e2e) are also integrated into this project and ran with Karma Test Runner and Protractor.

Github Repo

Installation

Backend

PHP version 5.4 at least is required.This is a requirement for RestFullYii extension

  • Clone the git repo git@github.com:drumaddict/angular-music-db.git - or download it,and copy it to your local server's public folder.Let's assume it's the webroot \.
  • Specify your local development domain in index.php,(constant LOCAL_DOMAIN) so that the configuration file can differentiate between local and production environment.For example,you can fill in database info for both environments and the script will figure it out,assuming your virtual host does'nt have the same domain name as your real host.
  • Hook up your Yii framework path in index.php,(both local and live on server).
  • Fill in database info in config/main.php and config/console.php.(both local and live on server).
  • Import the tables in your database from the sql file,protected/data/music_db.sql.Optionally you can import the user_table.sql,but this is related to the Yii application,not the one page application.
  • Verify that the Yii app is installed and responding (navigate to webroot \).

Frontend

  • Change directory to \music_db_src.This is the angular application source folder.
  • Install node.js
  • Install Grunt CLI with npm install -g grunt-cli
  • Install Bower globally with npm install -g bower.Bower is a package manager that will handle most of the frontend dependencies.
  • In music_db_src, run in your command line npm install.This command will read all the dependencies needed for development workflow from the package.json file.These dependencies will be downloaded in node_modules folder.
  • Once npm install is finished,run grunt install.This will install Protractor,an end to end (e2e) test framework for AngularJS.
  • Run bower install.This will read the bower.json file and download in libs folder all but four dependencies which are already in that folder:angular-table,angular-ui-router,assetsandtoastr.angular-table has been slightly modified for the purpose of the application,so downloading the original is not an option.angular-ui-router is a special build of Angular UI-Router when the version was 0.2.0 and supports keyframe CSS3 animations,which don't work for some reason with later versions.Last,I use a modified version of Toastr which exports it as window global.
  • Open music_db_src\libs\spinjs\spin.js and comment (remove) this line at the top of the file

    else if (typeof define == 'function' && define.amd) define(factory),

    so that spin exports as a window global.

  • This is it.You are ready to start development.

Development

  • Make sure you are always in music_db_srcfolder
  • Open js/config/Constants.ts and specify the application's base url.For development, this is APP_BASE_URL = '/music_db_src/'.Set your domain.For exmple,if you work in a virtual host (recommended) rest.dev,set DOMAIN='rest.dev'.You can change the credentials,but then you will have to change them on the server side also ,(see protected/config/restConfig.php).
  • Open Gruntfile.js,in env task,set the base URL for both development and production.You'll be OK if you leave the defaults (music_db_src and music_db).If for some reason you need to move the base source foldermusic_db_src in a deeper folder,you must include the whole path from the root.
  • Open App.ts and make sure 'templates-main' module is commented out.Also in loader.js you should comment out views in the final require call.This is enabled only for production to bake the partial html files into the javascript.
  • Run grunt copy:fontsdev to copy fonts from libs\bootstrap to libs\bootswatch folder.
  • Last,run simply grunt (shortcut for grunt dev).This task will compile the index.tpl.html file into index.html and also compile all the typescript files into one javascript file,app.js.Now point your browser to \music_db_src and the application should load.
  • You can now start developing.If you edit the typescript files they will automatically compile to app.js every time you save,because of a watcher registered in grunt ts task.Don't edit the compiled index.html file.If you need to edit the index file,you must edit index.tpl.html and then run grunt compileindex,to regenerate the new index.html.
  • If you take a look inside index.html,you will notice that there is only one script tag that loads loader.js.requirejs loads all javascript files in the right order based on loader.js requirejs configuration.

Tests

Karma Test Runner is used to run the tests.They are written for Jasmine.

Unit Tests

Unit tests are located in test\unit folder.test\karma-unit.conf.js is the configuration file and you don't need to change anything in it,at least for starters.There is a sample unit test for Resource.Resource is the class that makes all API calls to Yii.The test uses AngularJS's $httpBackend to fake a backend.To run the unit tests,in your command line,run grunt test:unit.

End To End (e2e) Tests

Make sure you have Java Runtime installed in your machine.

Open test\protractor.conf.js.You must specify the domain base url of your virtual host as baseUrl.For example baseUrl:'http://rest.dev'.Do the same in params.DOMAIN.Last,set params.BASE_URL to be the application base URL-default is\music_db_src\. You can find some sample tests in test\e2e.Make sure the data used in these tests is actual data in the database.Protractor acts like a robot,it will start the browser and perform actions like a real user,(navigate to a url,click a button, etc).See Protractor API for more details.When you have everything set up and ready,run grunt test:e2e,and the tests will run.

You can run both unit and e2e test in one go with grunt test.

Code Coverage

You can get code coverage reports with grunt test:coverage.This task will genarate html code coverage reports in coverage folder.

Production

When you compile the project for production,a music_dbfolder will be generated,sibling to music_db_src.Before you compile for production,you must change APP_BASE_URL in music_db_src\config\Constants.ts.Remember,it was \music_db_src\ for development,now it has to change to \music_db\.In Gruntfile.jsin env task,make sure env.prod.BASEURL is also set to \music_db\. In App.ts,uncomment(enable) the templates-main module,and in loader.js uncomment views in final require call.Last,run grunt prod.This task will compile the typescript files, compile the index.tpl.html file ,concatenate and minify all javascript files (single minified javascript file output),concatenate and minify the css,minify the one and only html file,bake partial html files into a single views.jsfile which will be merged with the rest of the javascript,optimize the images and last,copy all files to music_db.Point the browser to \music_db and the application should load.

NOTICE. It is recommended that you stick with the dependency versions declared in package.json,bower.json as the application is fine tuned to use these.This is specially true with code that is under rapid development like angular-ui-router and Protractor.

Please consider that my instructions are based on my Windows7 development environment,I guess most of it is valid no matter what your environment is.

Thanks

Thanks for the angular exams. This one is good too like the other for gallery collection.
