Use FastAPI to create a desktop application (no Electronjs)

#python3 #fastapi #gui #electron

Not only JS folks can do it we can do it too!

First, install this library:

pip install flaskwebgui
Enter fullscreen mode Exit fullscreen mode

Next add the following code in a main.py file:

#main.py  from fastapi import FastAPI from flaskwebgui import FlaskUI # import FlaskUI  app = FastAPI() ui = FlaskUI(app) # feed app and parameters  @app.get("/") def read_root(): return {"message": "Works with FastAPI!"} if __name__ == "__main__": ui.run()
Enter fullscreen mode Exit fullscreen mode

Alternatively, next to main.py create a file called gui.py and add the following contents:

#gui.py  from flaskwebgui import FlaskUI from main import app FlaskUI(app, width=600, height=500).run()
Enter fullscreen mode Exit fullscreen mode

Next start the application with:

python main.py #or python gui.py #in case you created gui.py
Enter fullscreen mode Exit fullscreen mode

Fastapi will be served by uvicorn.

And that's all!

I'm getting the error AttributeError: 'FastAPI' object has no attribute 'after_request' whether I run python main.py or python gui.py.

I have flaskwebgui, flask and fastapi installed ok.

Had to change the startup in both files to FlaskUI(app, start_server='fastapi', width=600, height=500).run()
