```shell ```shell
nx watch --projects=app1 --includeDependentProjects -- echo \$NX_PROJECT_NAME nx watch --projects=app1 --includeDependentProjects -- echo \$NX_PROJECT_NAME
``` ```
### Rebuilding dependent projects while developing an application
In a monorepo setup, your application might rely on several libraries that need to be built before they can be used in the application. While the [task pipeline](/recipes/running-tasks/defining-task-pipeline) automatically handles this during builds, you'd want the same behavior during development when serving your application with a dev server.
To watch and rebuild the dependent libraries of an application, use the following command:
```shell
nx watch --projects=my-app --includeDependentProjects -- nx run-many -t build -p \$NX_PROJECT_NAME --exclude=my-app
```
`--includeDependentProjects` ensures that any changes to projects your application depends on trigger a rebuild, while `--exclude=my-app` skips rebuilding the app itself since it's already being served by the development server.
