svc-example

An example service using

• systemic
• confabulous
• prepper
• systemic-express
• systemic-pg
• marv
• groundhog-day

Features

• Environmental configuration
• Secrets obtained from a runtime location
• Automatically applies schema changes on startup
• Orderly startup / shutdown (e.g. establishes database connections before setting up http listeners and vice versa)
• Graceful shutdown on errors, unhandled rejections, unhandled exceptions, SIGINT and SIGTERM
• Useful log decorators, including request scoped logging
• JSON logging to stdout in "proper" environments, human friendly logging locally
• The Dockerfile uses settings from .npmrc and .nvmrc
• The docker build cache busts using package.json and npm-shrinkwrap.json so npm install only runs when necessary
• Deployed artifact (a docker image) is traceable back to SCM commit via manifest.json, exposed via /__/manifest endpoint
• Unit tests use stubbed clock for predictability
• Unit tests use stubbed persistence store for speed
