# Angular 2 QuickStart Source [![Build Status][travis-badge]][travis-badge-url] This repository holds the TypeScript source code of the [angular.io quickstart](https://angular.io/docs/ts/latest/quickstart.html), the foundation for most of the documentation samples and potentially a good starting point for your application. It's been extended with testing support so you can start writing tests immediately. **This is not the perfect arrangement for your application. It is not designed for production. It exists primarily to get you started quickly with learning and prototyping in Angular 2** We are unlikely to accept suggestions about how to grow this QuickStart into something it is not. Please keep that in mind before posting issues and PRs. ## Prerequisites Node.js and npm are essential to Angular 2 development. Get it now if it's not already installed on your machine. **Verify that you are running at least node `v5.x.x` and npm `3.x.x`** by running `node -v` and `npm -v` in a terminal/console window. Older versions produce errors. We recommend [nvm](https://github.com/creationix/nvm) for managing multiple versions of node and npm. ## Create a new project based on the QuickStart Clone this repo into new project folder (e.g., `my-proj`). ```bash git clone https://github.com/angular/quickstart my-proj cd my-proj ``` We have no intention of updating the source on `angular/quickstart`. Discard everything "git-like" by deleting the `.git` folder. ```bash rm -rf .git // non-Windows rd .git /S/Q // windows ``` ### Create a new git repo You could [start writing code](#start-development) now and throw it all away when you're done. If you'd rather preserve your work under source control, consider taking the following steps. Initialize this project as a *local git repo* and make the first commit: ```bash git init git add . git commit -m "Initial commit" ``` Create a *remote repository* for this project on the service of your choice. Grab its address (e.g. *`https://github.com//my-proj.git`*) and push the *local repo* to the *remote*. ```bash git remote add origin git push -u origin master ``` ## Install npm packages > See npm and nvm version notes above Install the npm packages described in the `package.json` and verify that it works: **Attention Windows Developers: You must run all of these commands in administrator mode**. ```bash npm install npm start ``` > If the `typings` folder doesn't show up after `npm install` please install them manually with: > `npm run typings -- install` The `npm start` command first compiles the application, then simultaneously re-compiles and runs the `lite-server`. Both the compiler and the server watch for file changes. Shut it down manually with Ctrl-C. You're ready to write your application. ### npm scripts We've captured many of the most useful commands in npm scripts defined in the `package.json`: * `npm start` - runs the compiler and a server at the same time, both in "watch mode". * `npm run tsc` - runs the TypeScript compiler once. * `npm run tsc:w` - runs the TypeScript compiler in watch mode; the process keeps running, awaiting changes to TypeScript files and re-compiling when it sees them. * `npm run lite` - runs the [lite-server](https://www.npmjs.com/package/lite-server), a light-weight, static file server, written and maintained by [John Papa](https://github.com/johnpapa) and [Christopher Martin](https://github.com/cgmartin) with excellent support for Angular apps that use routing. * `npm run typings` - runs the typings tool. * `npm run postinstall` - called by *npm* automatically *after* it successfully completes package installation. This script installs the TypeScript definition files this app requires. Here are the test related scripts: * `npm test` - compiles, runs and watches the karma unit tests * `npm run e2e` - run protractor e2e tests, written in JavaScript (*e2e-spec.js) ## Testing The QuickStart documentation doesn't discuss testing. This repo adds both karma/jasmine unit test and protractor end-to-end testing support. These tools are configured for specific conventions described below. *It is unwise and rarely possible to run the application, the unit tests, and the e2e tests at the same time. We recommend that you shut down one before starting another.* ### Unit Tests TypeScript unit-tests are usually in the `app` folder. Their filenames must end in `.spec`. Look for the example `app/app.component.spec.ts`. Add more `.spec.ts` files as you wish; we configured karma to find them. Run it with `npm test` That command first compiles the application, then simultaneously re-compiles and runs the karma test-runner. Both the compiler and the karma watch for (different) file changes. Shut it down manually with Ctrl-C. Test-runner output appears in the terminal window. We can update our app and our tests in real-time, keeping a weather eye on the console for broken tests. Karma is occasionally confused and it is often necessary to shut down its browser or even shut the command down (Ctrl-C) and restart it. No worries; it's pretty quick. The `HTML-Reporter` is also wired in. That produces a prettier output; look for it in `~_test-output/tests.html`. ### End-to-end (E2E) Tests E2E tests are in the `e2e` directory, side by side with the `app` folder. Their filenames must end in `.e2e-spec.ts`. Look for the example `e2e/app.e2e-spec.ts`. Add more `.e2e-spec.js` files as you wish (although one usually suffices for small projects); we configured protractor to find them. Thereafter, run them with `npm run e2e`. That command first compiles, then simultaneously starts the Http-Server at `localhost:8080` and launches protractor. The pass/fail test results appear at the bottom of the terminal window. A custom reporter (see `protractor.config.js`) generates a `./_test-output/protractor-results.txt` file which is easier to read; this file is excluded from source control. Shut it down manually with Ctrl-C. [travis-badge]: https://travis-ci.org/angular/quickstart.svg?branch=master [travis-badge-url]: https://travis-ci.org/angular/quickstart # EdAngular2
