Dev Setup for Lovefield

Java, Git, Node.js

You will need to have Java, git, and Node.js in a working state. They must be searchable from your PATH.

Lovefield uses node.js for various development tools, see package.json for suggested version.

Special Notes for Windows Users

Windows Command Prompt has a limitation of command-line length, which will cause Closure compiler failure since the compiler requires a command-line way longer than that limit. The solution is to install a command line utility, such as TCC/LE, to overcome that limitation.

Set Up Dev Environment

  1. Install dependencies

Lovefield uses npm as its dependency manager. Run npm update to install packages required by Lovefield.

  1. Build Lovefield

Lovefield uses Closure JavaScript Compiler to validate/minify/uglify its code. The compiler is brought down by npm automatically.

Lovefield uses gulp as its build manager. Run gulp to see the commands supported.

  1. Test Lovefield

Lovefield uses Selenium WebDriver to run automated test. There are two ways of running unit tests:

a. Test locally

You will need to download and install the WebDrivers manually. Then run gulp test --target=tests --browser=<browser> to test locally. Local testing are supposed to be used for debugging and quick turn around.

b. Test using Sauce Labs

You will need to register an account on Sauce Labs, and run Sauce Connect on your computer. Then run the following script (assuming Linux/Mac and bash is used, Windows users please adjust the script to fit your environment):

export SAUCE_USERNAME=<your username>
export SAUCE_ACCESS_KEY=<your sauce token>
export SELENIUM_BROWSER=chrome
gulp test --target=tests
export SELENIUM_BROWSER=firefox
gulp test --target=tests
export SELENIUM_BROWSER=ie
gulp test --target=tests
export SELENIUM_BROWSER=safari
gulp test --target=tests

You can find your user name and sauce token here.

  1. Make contributions

Make sure you are okay with the rules in CONTRIBUTING. If not, you can stop reading here.

For your contribution to be accepted, your change must pass the following commands (again, assuming Linux/Mac):

gulp build --target=lib --mode=opt
gulp build --target=tests
gulp lint
gulp test --target=spac
export SAUCE_USERNAME=<your username>
export SAUCE_ACCESS_KEY=<your sauce token>
export SELENIUM_BROWSER=chrome
gulp test --target=tests
export SELENIUM_BROWSER=firefox
gulp test --target=tests
export SELENIUM_BROWSER=ie
gulp test --target=tests
export SELENIUM_BROWSER=safari
gulp test --target=tests

JavaScript style is strictly enforced with no mercy. Unfortunately, the linter will not lint everything, so you may have more lints during code review.

Your pull request will not trigger Travis CI due to security concerns. As a result, you'll need to run the script above locally to avoid straight decline.

Markdowns

All Lovefield documents are in GitHub markdown format. Use one of your favorite editor/previewer for markdowns.
