@ember/app-blueprint

This is the blueprint that is used to generate a new Ember app using Vite as the primary build system.

If you have an existing app that you would like to upgrade to use Vite consider using the ember-vite-codemod

Usage

pnpm dlx ember-cli@latest new my-app-name -b @ember/app-blueprint --pnpm

Options

--no-compat

pnpm dlx ember-cli@latest new my-app-name \
  --blueprint @ember/app-blueprint@alpha \
  --pnpm \
  --no-compat

Does the following:

• enables type=module in package.json (required for vite-ssr, and many ESM tools)
• makes the build and boot MUCH FASTER
  (in large apps, this can have your app's boot be up to 1 minute faster)
• removes @embroider/compat
  • removes support for:
    • hbs (both for component files, and testing)
    • content-for (in the HTML files)
    • v1 addons
    • node-land config/environment.js
• removes ember-cli
  • ember-cli brings in a ton of old dependencies, so removing it makes installs much faster
  • downside though is that you no longer have scaffolding (ember g) -- however, you could use pnpm dlx ember-cli g ... (or npx ember-cli g)

--minimal

pnpm dlx ember-cli@latest new my-app-name \
  --blueprint @ember/app-blueprint@alpha \
  --pnpm \
  --minimal

Does the following

• everything listed under --no-compat
• Removes all linting, formatting, and testing support
  • leaves you with a minimal app that you can use for demos, and PRing to other repositories that have multi-framework support (and probably use other testing tools for that multi-framework support)
• different defaults:
  • warp-drive becomes opt-in (pass --warp-drive if you want it -- normally requires --no-warp-drive to remove)
  • ember-welcome-page becomes opt-in (normally requires --no-welcome to remove)
