Scenario instructions:

Environment instructions:

The NestJs was already created using the `nest new` command.

You need to populate the following files:
src/app.controller.spec.ts
src/app.controller.ts
src/app.module.ts
src/app.service.ts
src/main.ts


Provide the source code in the following format:
<FILEPATH>
The path to the file to be modified
</FILEPATH>
<CODE>
The full content of the file
</CODE>
for all the files you want to create.

Example:
<FILEPATH>
path/to/file.py
</FILEPATH>
<CODE>
def hello_world():
    pass
</CODE>



Make sure that the command `npm run start` starts the app successfully.
