cd ionic

cd core npm install

Notice that @ionic/core lives in core.

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.

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.

1. npm run dev allows you to modify the components and have live reloading, just like another ionic app.

2. When everything looks good, run npm run validate to verify the tests linter and production build passes.
