Deploy a Python functions app on Enzonic

For small endpoints, skip the framework: a file in api/ with a handler(request) function becomes an endpoint. It can return a dict (sent as JSON), a string, bytes, or a (body, status, headers) tuple. ASGI and WSGI apps in api/ work too.

At a glance

What Enzonic Deploy does with a Python functions project when you connect it. You can override any of it in the project settings.

Language: Python
Detected from: api/*.py files, with no Django, FastAPI or Flask app detected first
Build command: pip install -r requirements.txt, if present
Output: Functions
Runs as: Functions

How it runs

Functions
Always.

Deploy Python functions step by step

1Create api/hello.py with a handler.
2Add requirements.txt if it imports packages.
3Deploy.

api/hello.py

def handler(request):
    name = request.query.get('name', 'world')
    return {'hello': name}

Connect a database to Python functions

Create a database on Enzonic Databases (or from the project's settings) and its connection string is added to the project's environment variables. This example uses Valkey.

api/cache.py

import os, redis

r = redis.from_url(os.environ['REDIS_URL'])

def handler(request):
    return {'hits': r.incr('hits')}

Postgres projects get two variables: DATABASE_URL through the connection pooler for the app, and DATABASE_URL_UNPOOLED for migrations.

Things to know

Module-level code runs once per warm instance: open connections there, not inside the handler.
