Development

Setting up your environment

After forking amp-toolbox to your own github org, do the following steps to get started:

# clone your fork to your local machine
git clone https://github.com/your-fork/amp-toolbox.git

# step into local repo
cd amp-toolbox

# install dependencies
npm install

# run tests
npm test

Adding new dependencies

amp-toolbox uses Lerna to manage it's packages. To keep build times low, devDependencies (but not CLI dependencies) must be added to the root package.json file. Runtime dependencies are managed for each package individually.

When adding a new package inside the packages directory, register the package via:

npm run bootstrap

Running Tests

The test suite runs for all packages and must be run from the root directory.

# run tests on node and browser
npm test

# run only in node (fastest)
npm run test:node

# run only in browser
npm run test:browser

Style & Linting

This codebase adheres to the Google Javascript Styleguide and is enforced using ESLint. ESLint is run as part of the test suite, but you can also explicity run it via:

# run ESLint
npm run lint

# run ESLint with `--fix` option to automatically fix errors (if possible)
npm run lint:fix
