Ember supports two different build environments:
- Our Vite integration works on all Ember versions back to 3.28. It became the default for newly-generated apps at Ember 6.8.
- The legacy ember-cli based build is also still supported on all Ember versions.
You can tell which one you're using based on the presence of @embroider/vite in your package.json file.
Existing apps can use Ember Vite Codemod to switch from the ember-cli based build to the Vite based build.
On Ember versions after 6.8, you can optionally choose to generate a new app using the older build environment via:
npx ember-cli@ new my-app-name -b @ember-tooling/classic-build-app-blueprint
