Building

In order to build seng-scroll-tracker, ensure that you have Git and Node.js installed.

Clone a copy of the repo:

git clone https://github.com/mediamonks/seng-scroll-tracker.git

Change to the seng-scroll-tracker directory:

cd seng-scroll-tracker

Install dev dependencies:

yarn

Use one of the following main scripts:

yarn build           # build this project
yarn dev             # run dev-watch mode, serving example/index.html in the browser
yarn generate        # generate all artifacts (compiles ts, webpack, docs and coverage)
yarn typings         # install .d.ts dependencies (done on install)
yarn test:unit       # run the unit tests
yarn validate        # runs validation scripts, including test, lint and coverage check
yarn lint            # run tslint on this project
yarn doc             # generate typedoc documentation

When installing this module, it adds a pre-push hook, that runs the validate script before committing, so you can be sure that everything checks out.
