Build
1. Clone ionic
git@github.com:ionic-team/ionic.git
cd ionic
2. Run npm install
cd core npm install
Notice that @ionic/core lives in core.
3. Run npm run dev
Make sure you are inside the core directory.
npm run dev
With the dev command, Ionic components will be built with Stencil, changes to source files are watched, a local http server will startup, and http://localhost:3333/ will open in a browser.
4. Preview
Navigate to http://localhost:3333/src/components/. Each component has small e2e apps found in the test directory, for example: http://localhost:3333/src/components/button/test/basic
As changes are made in an editor to source files, the e2e app will live-reload.
How to contribute
