FastAPI-Railway.app
A sample python FastAPI (api app) to run on Railway.app
To setup and run Railway app follow these steps https://docs.railway.app/getting-started
Few things different from the Flask example:
Main difference between Flask and FastAPI is, Flask is WSGI and FastAPI is ASGI so Flask gunicorn wont work with FastAPI, you need to use uvicorn instead of gunicorn.
- Procfile is modified to call the 'python main.py'
- main.py uses uvicorn to start the app from main function
- In uvicorn.run(...) along with the port it needs host="0.0.0.0" # I am not sure why this is required
This sample api includes a random number generator (with min and max limits)
App Routes
Route Root
localhost:8080/ returns {"Hello": "World from FastAPI"}
Route Random (Default)
localhost:8080/random returns a random number between 0 to 9 ex:- {"value":8}
Route Random with min/max
localhost:8080/random?min=100&max500 returns a random number between 100 and 500 ex:- {"value":421}
