FaunaDB User Token Expiration (for ABAC)

Auth0 + FaunaDB ABAC integration: How to expire Fauna user secrets.

Fauna doesn't (yet?) provide guaranteed expiration/TTL for ABAC tokens, so we need to implement it ourselves if we care about it.

What's in the box?

3 javascript functions, each of which can be imported into your project or run from the command-line using node path/to/script.js arg1 arg2 ... argN:

  1. deploy-schema.js: a javascript function for creating supporting collections and indexes in your Fauna database.

Logging setup for FastAPI, Uvicorn and Structlog (with Datadog integration)

Logging setup for FastAPI

This logging setup configures Structlog to output pretty logs in development, and JSON log lines in production.

Then, you can use Structlog loggers or standard logging loggers, and they both will be processed by the Structlog pipeline (see the hello() endpoint for reference). That way any log generated by your dependencies will also be processed and enriched, even if they know nothing about Structlog!

Requests are assigned a correlation ID with the asgi-correlation-id middleware (either captured from incoming request or generated on the fly). All logs are linked to the correlation ID, and to the Datadog trace/span if instrumented. This data "global to the request" is stored in context vars, and automatically added to all logs produced during the request thanks to Structlog. You can add to these "global local variables" at any point in an endpoint with `structlog.contextvars.bind_contextvars(custom

Micro event loop library to teach the basic concepts of python coroutines and how event loop libraries might be implemented
"""
A micro event loop library implementation from scratch.
This library provides a minimal but feature-complete asynchronous event loop
implementation for educational purposes. It demonstrates the core concepts of
asynchronous programming including:
- Task scheduling and management
- I/O multiplexing with non-blocking sockets
- Timeouts and sleep functionality
