func-az

Simple tools for Azure Functions

pip install func-az

Safe Start-up

Sometimes you deploy a function, and it breaks. And you have no idea why.

import azure.functions as func
import func_az as fz

def make() -> func.FunctionApp:
  ...

def handle_err(exc):
  logging.error(f'An error occurred during startup: {exc}')
  return 'An error occurred'

app = fz.startup(make, error_message=handle_err)

If it breaks, it sets up a /health route that you can use to trigger the handler.

Scheduled Job

You can set up a timer trigger, and also an HTTP trigger. But not both. This bridges the gap:

import azure.functions as func
import func_az as fz

app = func.FunctionApp()

@fz.job(app, 'greet-users', route='greet', timer='0 */5 * * * *')
async def greet_users():
  ...

Runs at the given timer, or can be triggered at /greet.
