Using shell=True with asyncio.create_subprocess_shell is redundant since create_subprocess_shell already executes commands through the shell by default. Consider using asyncio.create_subprocess_exec with the command split into arguments for better security and consistency with the other subprocess calls.

"npm run dev", stdout=sys.stdout, stderr=sys.stderr, cwd=MAGMA_PATH

Using shell=True with a list of arguments can lead to unexpected behavior and potential security issues. When using shell=True, the command should be passed as a string, not a list. Either change to string format or remove shell=True and handle Windows compatibility differently.
