Is it possible to use Codon with FastAPI?

[junoriosity]

I just came across codon, which seems to enable us to make Python-style code very fast.

Is it possible to combine FastAPI and Codon? If so, what are you experiences and do you have some code snippets at hand?

So I tried this, and cant seem to get the library imported:

from python import fastapi

from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
      return {"Hello": "World"}

I have the export CODON_PYTHON defined as well on a generic ubuntu system.

Here is the error im getting:

codon run main.py
main.py:5:6-13: error: no module named 'fastapi'
main.py:7:7-14: error: name 'FastAPI' is not defined
main.py:10:2-14: error: no module named 'app'
main.py:15:2-29: error: no module named 'app'

I was able to get farther doing:

from python import fastapi as fast

from typing import Union

#from fastapi import FastAPI

app = fast.FastAPI()


@app.get("/")
def read_root():
      return {"Hello": "World"}

But then got a PyError:

codon run main.py
PyError: ((), ()) is not a callable object
