Middleware factory for using a single transaction per request. Transactions are only started if a downstream handler requests one. If a transaction is started by the handler, it is automatically committed or rolled back once the handler completes.

Usage:

Enable the middleware:

app.use(makeDatabaseTransactionMiddleware(knex));

Python Dependency Management

Below is a very rough-and-ready summary of Python dependency management tools I have used.

An (incomplete) list of important factors of dependency management tooling:

Reproducibility - will committed files allow us to exactly reproduce an environment across dev machines, CI and production environments
Speed of resolution - how fast can a complete environment be resolved given a set of primary dependencies
Ease of management - how easy is it to upgrade one/all packages? how easy is it to add a new package? how easy is it to inspect the dependency graph?
Availability of packages - can I get the packages I need?

Logs

Stream logs from Elasticsearch to stdout.

Requirements

Python 3.8 or higher

pip install python-dateutil==2.8.2 fire==0.4.0 requests==2.26.0

K3s for local testing/CI

The following is a docker-compose k3s configuration, with a script to pre-populate images in the cluster, allowing complete tear-down and rebuild very quickly.

This could be useful for spinning up a small cluster during CI jobs, as it allows the images to be cached rather than pulled into the newly built cluster for each and every job.

Results from local testing:

| | No preloaded images | Preloaded images |

OpenAPI Combinator

Web app which combines OpenAPI specifications into a single specification.

Requirements:

fastapi ~= 0.63.0
httpx ~= 0.16.1
aiocache ~= 0.11.1
