too many include_router

[me-v2]

A big application, with many routers. how move a separate file ？

app.include_router(router1)
app.include_router(router2)
app.include_router(router3)
app.include_router(router4)
app.include_router(router5)
....

Probably it's not a direct answer to your question, but I found it useful to have all FastAPI initialization logic in factory function in separate file:

from collections.abc import Callable
from logging import Formatter
from logging.handlers import RotatingFileHandler
from typing import Any

from fastapi import FastAPI, Request, status
from fastapi.logger import logger
from fastapi.responses import JSONResponse

from settings import Settings
#import all routers here

def create_api(settings: Settings):
    handler = RotatingFileHandler(
        filename=settings.logging_filename,
        maxBytes=settings.logging_max_bytes,
        backupCount=settings.logging_backup_count,
        encoding=settings.logging_encoding
    )
    handler.setFormatter(Formatter(settings.logging_format))
    logger.addHandler(handler)

    api = FastAPI(title='API')

    @api.middleware('http')
    async def catch_exceptions_middleware(request: Request, call_next: Callable[[Request], Any]):
        try:
            return await call_next(request)
        except Exception as error:
            logger.error(error, exc_info=(type(error), error, error.__traceback__))
            return JSONResponse(
                status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
                content={
                    'detail': 'Internal Server Error'
                }
            )
    
    #include all routers here:
    api.include_router(...)
    
    return api

Settings is my custom class for settings, you may not use it if you don't want. I just import create_api function and instantiate FastAPI instance in the same way under different circumstances (for normal run, for tests, for CLI, etc.)

Like the above answer mentioned, you can seperate the pproject into apps and include all the routers to the app, then finally include all the routers to the main url.py app

thks, guys. A solution below:
I use a function :

include_routers(app)
