Features

• App factory pattern

  • blueprints (web & CLI)

  • custom command
  • two-phase init for blueprints

• Configuration

  • .env & .flaskenv
  • from files
  • from environment
  • alternate settings for testing, dev, prod

• Logging

  • logs are probably cheap, don't prematurely optimize
  • centralize your logs to an aggregation service
  • .info logs are show/saved by default
  • cli output is plain text
  • saved logs are JSON
  • saved logs go to syslog, let devops handle the aggregation

• Testing

  • alternate DB URI
  • pytest & fixtures

• Flask-SQLAlchemy

  • ext init
  • fixtures to get db to ensure app context

• Celery

  • refresh process pool

• cli integration with the ability to customize the app's configuration using global cli options

  someapp --debug --with-sentry run-some-task

• pytest fixtures for app initialization

• demo cli test that uses separate process

Copier Template

Project structure and tooling mostly derives from the Coppy, see its documentation for context and additional instructions.

This project can be updated from the upstream repo, see Updating a Project.

Project Setup

From zero to hero (passing tests that is):

1. Ensure host dependencies are installed

2. Start docker service dependencies (if applicable):

   docker compose up -d

3. Sync project virtualenv w/ lock file:

   uv sync

4. Configure pre-commit:

   pre-commit install

5. Run tests:

   nox

Versions

Versions are date based. A bump action exists to help manage versions:

  # Show current version
  mise bump --show

  # Bump version based on date, tag, and push:
  mise bump

  # See other options
  mise bump -- --help
