@artlife/micro v0.0.73

micro

A tiny and very opinionated microservices framework inspired by expressjs.

This library hosts all the common and boring features shared between our microservices.

WARNING: This library is a work in progress and isn't intended to be general purpose.

Things like:

• logging
• basic error handling
• metrics
• health checks
• tracing requests and events across services

Environment variables

Configuration of the microserver can be done via environment variables (if not configure specifically in the code):

• HOST - Sets the host for the REST API (defaults to 0.0.0.0).
• PORT - Sets the port number for the REST API (defaults to 3000).
• MESSAGING_HOST - Sets the connection to the RabbitMQ server (defaults to amqp://guest:guest@localhost:5672).
• NODE_ENV - When set to PRODUCTION Morgan request tracing is disabled.
• ENABLE_MORGAN - When set to "true" Morgan request tracing is enabled (can be used to enable request tracing in production).
