Word puzzle game

demo: https://tibulca.github.io/wordgame/build/ remaining tasks:

• currently there is only a mock implementation of IWordFeedService. A new implementation that will use Firebase has to be implemented
• unit tests are not complete (only 3 for demo purpose were created). The services and components are not covered yet.
• the UX has to be improved
• the Game class can be splited into an entity + a service

Below is the readme of the starter kit I used to develop the game app.

angular-next-starter-kit

Seed project for developing angular 1.x applications in preparation for migrating on to Angular 2.0

Angular 2.0 brings in quite a few new concepts and design patterns. However, Angular 2.0 is a few months away from being production ready. For those starting off with an Angular 1.x application but want to use the concepts of Angular 2.0 and some of the technologies used in Angular 2.0 today, then this starter kit may serve the purpose.

The goals of this project is simple:

• Focus on the application logic by:
  • Create a service to get some data (see Creating a Service below)
  • Create a component to use the data (see Creating a Component below)
  • Compose larger components using smaller components

The developer DOES NOT have to worry about the following:

• Configuring a build system
• Configuring unit tests, end-to-end tests, code coverage
• Provide static analysis and configure typescript
• Automatically generate documentation

Features

• Complete scaffolding with Angular 1.4.x
• Typescript integration
• Webpack bundling system with multiple loaders (sass, html, typescript)
• Gulp integration (currently only one task to provide auto documentation)
• Karma integration with Mocha, Chai, multiple browser launchers (Chrome, PhantomJS) and code coverage
• Interfaces and APIs to create testable and reusable components
• Various kinds of service interface
  • Http Service
  • Socket Service using Socket IO
  • SOAP Service using soap client
  • Buffer Service using ProtobufJS

Framework

• Angular 1.4.x
• Bootstrap (sass) 3.3.6
• Socket IO Client 1.3.7
• Typescript v1.7.5

Build

• Webpack
• Gulp

Test

• Karma
• Mocha
• Chai
• Protractor

Getting Started

To get started using the seed project, complete the following steps:

Clone the current repository

git clone https://github.com/alamgird/angular-next-starter-kit.git

Install all dependencies

There are two kinds of dependencies in this project:

1. NPM dependencies which are used for development as well as application code
2. Typescript dependencies which are the definitely typed files for some of the NPM modules

The following command will continue to install all dependencies:

npm run setup

Run the application

To run the application with a development server with hot module reload, run the following command:

npm run serve

Run the tests

To run the unit tests for the application, run the following command:

npm test

Integration tests are on their way.

Package the application

To produce a bundled application, run the following command:

npm run build

Creating a Service

Suppose we want to create a service that gets Stock Quote from Dev Markit API. The service will take a symbol and return a quote.

Create a file under app/services/stock-service. All services should go under app/services.

First define a Quote object

export interface Quote {
 name: string,
 symbol: string,
 lastPrice: number,
 high: number,
 low: number,
 open: number
}

Since typescript is used, the fields in the Quote object can be strongly typed. The interface should be exported since it may be used in other parts of the application. These interfaces can also be moved to a common file.

Create an extension of HttpService interface

An HttpService interface is already provided. Angular's $http service is automatically injected. All that needs to be done is a new class should be created implementing the service logic.

export class StockService extends HttpService {

 getQuote(symbol: string): ng.IPromise<Quote> {
  var url = `http://dev.markitondemand.com/MODApis/Api/v2/Quote/jsonp?symbol=${symbol}&callback=JSON_CALLBACK`;
  return this.jsonp(url);
 }

}

The getQuote method takes a string argument and returns an ng.IPromise which should eventually resolve to a Quote object. To read mode about angular's definitely typed objects, visit AngularJS DefinitelyTyped. It is very clear from the code what this service does and what the method returns.

Lastly, register the service

An angular module app.services is readily available:

angular.module('app.services').service('stockService', StockService);

Now, this service is ready to be injected into any component.

Creating a Component

All components should go under app/components/[component-name].

A component should be composed of 4 files

• [component-name].html - Template for the component
• [component-name].scss - Scoped styles for the component
• [component-name].spec.ts - Unit test for the component
• [component-name].ts - Implementation of the component logic

Suppose we want to create a drop down component. Intuitively, the component should be used like this:

<dropdown
  name="My Dropdown"
  items="[{ href: '#', label: 'Item 1' },{ href: '#', label: 'Item 2' }]">
</dropdown>

Create a template (dropdown.html):

<div component="DropDown" class="dropdown">
    <button class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true"     
            aria-expanded="true">
        {{ ctrl.name }}
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu">
        <li ng-repeat="item in ctrl.items">
            <a href="{{ item.href }}">{{ item.label }}</a>
        </li>
    </ul>
</div>

Create a scoped stylesheet (dropdown.scss):

[component="DropDown"] {
  &.dropdown {
    a {
      color: pink !important;
    }
  }
}

Create the component implementation (dropdown.ts) by extending the BaseComponent:
