I joined to project in the middle of development process exactly when I was starting my adventure with AgularJS. Before this I read some guides and tutorials, but it was just about single html file, without any additional routing directives such as ng-route or ui-router. When I wanted to start a new project, it was really hard to create basic files with simple routing. Of course there are a lot of tools such as yeoman, but at the beginning of coding, and for small projects, this tool is too extensive, because it has many you will never use. So this is why I decided to create a small skeleton with simple routing, easy to test and deploy.

##Development You may download the repository from github -

The skeleton contains:

  • bower.json - provides libraries names to be downloaded to the project with bower install task
  • Gruntfile.js - provides definitions for grunt tasks (installing libraries with grunt-bower-task)
  • package.json - contains information about dev dependencies, server dependencies, and npm start task
  • Procfile - application runner file, it can be used only with Heroku (if you don't use Heroku, you may delete it)
  • server.js - server runner script
  • app - directory containing project sources

Before you run the project and start development, you have to install dependencies and project libraries. Just open command line and run commands:

  • npm install - dev dependencies installation
  • grunt - project libraries installation
  • npm start - local server runner (localhost:5000 by default)

Now application skeleton is ready to preview, just type localhost:5000 in your favourite browser. I prefer Google Chrome for develop puproses, it has a lot of useful extensions such as Batarang.

##Project structure

As you can see, each view has its own files (view, controller, service), they are placed in a separated directory, why? Becauce AngularJS is an MVC framework, and the bigger your project is, the better you control over it. Just read the article below, you will find more about AngularJS good practises.

Other JavaScript files are inside js directory, but if your project is bigger, you should place them in separate directories.

This skeleton has two views: test and test2. The views are managed by config located in app.js file. For better understanding of views routing, please read ui-router documentation.

I put some constants in config.js file. Currently it contains server name for mocking purposes.

##Views ####View1

The first view - test - it is available for everybody, it contains:

  • link to test2 view (it redirects only if you are logged in)
  • user authorization status
  • test variable value
  • result of simple http GET method
  • ng-repeat directive
  • login button (it performs logging in process - setting token value in LoggedUser factory)

Of course logging in process logic (saving session token and others) should be made using communication with your backend server, inside onLoginSuccess function, which you should create after login success response is received.

If you click LogIn button, you will be logged in, and you may click TEST2 link, to go to test2 view.

I assume you noticed the url has been changed. The value following the # char has changed to /test2. It is the result of states definions in app.js file.


The second view contains:

  • link to test view
  • user authorization status
  • sample text
  • logout button (it performs logging out process - setting token value to undefined, it means that user is logged out)

##Project evolution

The js directory also contains CookiesService.js and LoggedUser.js files. CookiesService is a manager of cookies, it supplies methods to set, get and delete cookies. LoggedUser is a factory and it represents user state. Because factories and services are singletons in Angular, the factory state is kept between views change. This solution and 'resolve' section in routing option(in app.js file) allow to route perfectly between states. (you should use it for routing between authorized and unauthorized states).

##Evolution example

Now you may add new views and Controllers. To do it, just create the new subdirectory in views directory, and place proper html and js files.

Don't forget about new state in app.js file, do it with new state section, as you can see at the screenshot below. You must also load freshly created controller. (in index.html - just like the others) Remember, that service has to be loaded before corresponding controller, because you use it usually as dependency in controller file.

Now you may type http://localhost:5000/#/newview address in your browser, to see the result of creating new view of your single-page application.

The rest of files are very similar to other AngularJS project files, but from my point of view, the most important is project organization and files structure. I hope this short note will help you to get better start with your first Angular project.
