# Building and Testing Angular 2 for JS
|
|
|
|
This document describes how to set up your development environment to build and test Angular 2 JS version.
|
|
It also explains the basic mechanics of using `git`, `node`, and `npm`.

|
See the [contribution guidelines](https://github.com/angular/angular/blob/master/CONTRIBUTING.md)
|
|
if you'd like to contribute to Angular.
|
|
|
|
## Prerequisite Software
|
|
|
|
Before you can build and test Angular, you must install and configure the
|
|
following products on your development machine:
|
|
|
|
* [Git](http://git-scm.com) and/or the **GitHub app** (for [Mac](http://mac.github.com) or
|
|
[Windows](http://windows.github.com)); [GitHub's Guide to Installing
|
|
Git](https://help.github.com/articles/set-up-git) is a good source of information.
|
|
|
|
* [Node.js](http://nodejs.org), (version `>=5.4.1 <6`) which is used to run a development web server,
|
|
run tests, and generate distributable files. We also use Node's Package Manager, `npm`
|
|
(version `>=3.5.3 <4.0`), which comes with Node. Depending on your system, you can install Node either from
|
|
source or as a pre-packaged bundle.
|
|
|
|
* [Java Development Kit](http://www.oracle.com/technetwork/es/java/javase/downloads/index.html) which is used
|
|
to execute the selenium standalone server for e2e testing.
|
|
|
|
## Getting the Sources
|
|
|
|
Fork and clone the Angular repository:
|
|
|
|
1. Login to your GitHub account or create one by following the instructions given
|
|
[here](https://github.com/signup/free).
|
|
2. [Fork](http://help.github.com/forking) the [main Angular
|
|
repository](https://github.com/angular/angular).
|
|
3. Clone your fork of the Angular repository and define an `upstream` remote pointing back to
|
|
the Angular repository that you forked in the first place.
|
|
|
|
```shell
|
|
# Clone your GitHub repository:
|
|
git clone git@github.com:<github username>/angular.git
|
|
|
|
# Go to the Angular directory:
|
|
cd angular
|
|
|
|
# Add the main Angular repository as an upstream remote to your repository:
|
|
git remote add upstream https://github.com/angular/angular.git
|
|
```
|
|
## Installing NPM Modules
|
|
|
|
Next, install the JavaScript modules needed to build and test Angular:
|
|
|
|
```shell
|
|
# Install Angular project dependencies (package.json)
|
|
npm install
|
|
```
|
|
|
|
**Optional**: In this document, we make use of project local `npm` package scripts and binaries
|
|
(stored under `./node_modules/.bin`) by prefixing these command invocations with `$(npm bin)`; in
|
|
particular `gulp` and `protractor` commands. If you prefer, you can drop this path prefix by either:
|
|
|
|
*Option 1*: globally installing these two packages as follows:
|
|
|
|
* `npm install -g gulp` (you might need to prefix this command with `sudo`)
|
|
* `npm install -g protractor` (you might need to prefix this command with `sudo`)
|
|
|
|
Since global installs can become stale, and required versions can vary by project, we avoid their
|
|
use in these instructions.
|
|
|
|
*Option 2*: defining a bash alias like `alias nbin='PATH=$(npm bin):$PATH'` as detailed in this
|
|
[Stackoverflow answer](http://stackoverflow.com/questions/9679932/how-to-use-package-installed-locally-in-node-modules/15157360#15157360) and used like this: e.g., `nbin gulp build`.
|
|
|
|
## Windows only
|
|
|
|
In order to create the right symlinks, run **as administrator**:
|
|
```shell
|
|
./scripts/windows/create-symlinks.sh
|
|
```
|
|
|
|
Before submitting a PR, do not forget to remove them:
|
|
```shell
|
|
./scripts/windows/remove-symlinks.sh
|
|
```
|
|
|
|
## Building
|
|
|
|
To build Angular run:
|
|
|
|
```shell
|
|
./build.sh
|
|
```
|
|
|
|
* Results are put in the dist folder.
|
|
|
|
## Running Tests Locally
|
|
|
|
To run tests:
|
|
|
|
```shell
|
|
$ ./test.sh node # Run all angular tests on node
|
|
|
|
$ ./test.sh browser # Run all angular tests in browser
|
|
$ ./test.sh browserNoRouter # Optionally run all angular tests without router in browser
|
|
|
|
$ ./test.sh tools # Run angular tooling (not framework) tests
|
|
```
|
|
|
|
You should execute the 3 test suites before submitting a PR to github.
|
|
|
|
All the tests are executed on our Continuous Integration infrastructure and a PR could only be merged once the tests pass.
|
|
|
|
- CircleCI fails if your code is not formatted properly,
|
|
- Travis CI fails if any of the test suites described above fails.
|
|
|
|
## Update the public API tests
|
|
|
|
If you happen to modify the public API of Angular, API golden files must be updated using:
|
|
|
|
``` shell
|
|
$ gulp public-api:update
|
|
```
|
|
|
|
Note: The command `./test.sh tools` fails when the API doesn't match the golden files.
|
|
|
|
## Formatting your source code
|
|
|
|
Angular uses [clang-format](http://clang.llvm.org/docs/ClangFormat.html) to format the source code. If the source code
|
|
is not properly formatted, the CI will fail and the PR can not be merged.
|
|
|
|
You can automatically format your code by running:
|
|
|
|
``` shell
|
|
$ gulp format
|
|
```
|
