$ cd craster
$ npm install

You can then use the following command:

$ bin/craster

To test in a browser, you can use --server --port 9000 to keep the server open on a given port. You may need to launch a browser with CORS disabled. E.g., for Chrome under OS X:

$ open -na /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
  --args --user-data-dir="/tmp/chrome_dev_test" --disable-web-security

Release

Make sure you have the jq package installed.

Then change the version in package.json, update the CHANGELOG.md, then:

$ npm install
$ git add package.json package-lock.json CHANGELOG.md
$ git commit -m v`jq -r '.version' < package.json`
$ git tag v`jq -r '.version' < package.json`
$ git push && git push --tags
$ npm publish
