vscode launch.json debugpy

[rajivharris]

I am trying to debug python fastapi application using vscode launch.json. I have the below configuration, but it is not working as vscode not able to find hatch module.

  {
      "name": "Hatch: FastAPI",
      "type": "debugpy",
      "request": "launch",
      "module": "hatch",
      "args": ["run", "dev"],
   }

pyproject.toml configuration to run FastAPI

[tool.hatch.envs.default.scripts]
dev = "uvicorn src.main:app --reload --port 8081"

Is module supposed to be the name of a command line app or a Python function?

I'm wondering how to do the same thing but in django

I use the same launch configuration and it works in normal mode. But debugging doesnt work.. I guess its because the hatch binary is used. Is there another way to start hatch via python directly?

        {
            "name": "TestRunner: Hatch",
            "type": "debugpy",
            "request": "launch",
            "module": "hatch",
            "console": "integratedTerminal",
            "args": ["run", "py3.12:tr"],
            "cwd": "D:\\Testsuite",
            "justMyCode": false
        },

if you use the binary you can do hatch self python -m hatch

Yeah you are right. I wasnt aware that vscode starts hatch with -m hatch when "module" key is used. xD

But even if i set a breakpoint in hatchs __ main __.py the vscode debugger wont stop.

Then i changed the directory where the venv is installed to be inside my vscode workspace.
See https://hatch.pypa.io/latest/config/hatch/
via
[dirs.env]
virtual = XXX

After that i needed to start hatch via the --config option because i didnt want to change the "main" config of hatch.
Then the debugger worked... at least within hatchs code itself.

But i saw hatch is starting a new python interpreter with the subprocess module with shell=True

I dont know why but, when i change it to False and correct the executable path as format_for_subprocess does debugging works!

Can this behavior be configured from outside?
