Angular and TypeScript JumpStart example

Angular JumpStart with TypeScript

The goal of this jumpstart app is to provide a simple way to get started with Angular 2+ while also showing several key Angular features. The sample relies on System.js to load TypeScript modules and the required scripts used in the application.

Angular Concepts Covered

• TypeScript version that relies on classes and modules
• Modules are loaded with System.js
• Defining routes including child routes and lazy loaded routes
• Using Custom Components including custom input and output properties
• Using Custom Directives
• Using Custom Pipes
• Defining Properties and Using Events in Components/Directives
• Using the Http object for Ajax calls along with RxJS observables
• Working with Utility and Service classes (such as for sorting and Ajax calls)
• Using Angular databinding Syntax [], () and [()]
• Using template-driven and reactive forms functionality for capturing and validating data
• Optional: Webpack functionality is available for module loading and more (see below for details)
• Optional: Ahead-of-Time (AOT) functionality is available for a production build of the project (see below for details)

Running the Application

1. Install Node.js 6.5 or higher. IMPORTANT: The server uses ES2015 features so you need Node 6.x or higher!!!!

2. Run npm install to install app dependencies

3. Run npm start in a separate terminal window to build the TypeScript, watch for changes and launch the web server

4. Go to http://localhost:3000 in your browser

Simply clone the project or download and extract the .zip to get started. Here are a few screenshots from the app:

Running the Application using WebPack (and optionally AOT)

The Angular JumpStart application uses System.JS by default for module loading mainly to keep the app as simple as possible and focused on Angular concepts rather than on a ton of configuration. However, Webpack can also be used to handle working with modules plus perform tasks such as bundling, minification, conversion of TypeScript to JavaScript, start up a dev web server and much more.

If you'd like to use WebPack instead of SystemJS you'll need to modify a few things in the application. Here's a list of the required steps to get the application going using Webpack:

1. Do a global search and replace in the project to comment out all references to moduleId in each component since it isn't used by Webpack: Find: moduleId: module.id,

   Replace with: //moduleId: module.id,

If you plan on only using Webpack and not going back to SystemJS you can completely remove moduleId: module.id, if you'd like.

1. Open src/app/app-routing.module.ts and change app/ to ./ for all loadChildren paths. For example:

   Change: loadChildren: 'app/customers/customers.module#CustomersModule'

   To: loadChildren: './customers/customers.module#CustomersModule'

2. Run npm install to install app dependencies

3. Optional (for AOT). If you'd like to run the application using Ahead of Time (AOT) compilation, run the following command to set the NODE_ENV environment variable to production and create an AOT build:

   Mac: export NODE_ENV=production *Windows: set NODE_ENV=production

4. Run npm run build in a console window. This will generate the required script assets needed to run the application and place them in the src/devDist folder for a development build or src/dist for a production/AOT build (if you performed the previous step). It will also watch for any code changes that are made and rebuild the script bundles as needed.

5. Run node server.js in another command window to start the server.

6. Navigate to http://localhost:3000 in a browser.
