 [Vue CLI](https://cli.vuejs.org/) is the official webpack-based toolchain for Vue. It is now in maintenance mode and we recommend starting new projects with Vite unless you rely on specific webpack-only features. Vite will provide superior developer experience in most cases.

 ### Note on In-Browser Template Compilation
 
 When using Vue without a build step, component templates are written either directly in the page's HTML or as inlined JavaScript strings. In such cases, Vue needs to ship the template compiler to the browser in order to perform on-the-fly template compilation. On the other hand, the compiler would be unnecessary if we pre-compile the templates with a build step. To reduce client bundle size, Vue provides [different "builds"](https://unpkg.com/browse/vue@3/dist/) optimized for different use cases.
