All of these commands require you to run npm install first. Add the --typecheck flag to generate type definitions (.d.ts) and do type checking, but keep in mind builds and rebuilds when watching will be significantly slower (~1min and ~1s respectively, vs ~20s and ~200ms without typechecking).

Installing Nightly Version

Releasing Component Demos

Ionic Component demos are automatically compiled and deployed to the ionic staging site on every commit in ionic-preview-app. No action is necessary.

If you'd like to manually update the demos, follow the steps on the preview app for running locally on the site.

Releasing API Demos

Ionic API demos are automatically compiled and deployed to the ionic staging site on every commit. No action is necessary.

If you'd like to manually update the demos, clone the ionic-site repo as a sibling of ionic. From ionic run gulp demos and then gulp docs, and it'll compile and copy the demos to the ionic-site repo, ready for testing.
