@ui5/cli
The UI5 Tooling command line for project setup, the local dev server and the build, which defines a UI5 project's shape and its two extension points, custom middleware and custom tasks.
Defines the shape of a UI5 project and the two extension points the ecosystem hangs off — custom middleware for serving and custom tasks for building.
