DB handler mixin for Moleculer DB

It supports using MongoDB at development & production and using NeDB at unit testing.

Features

• use NeDB memory DB for unit testing (NODE_ENV=test).
• use NeDB file storage if NEDB_FOLDER is defined.
• use other empty MongoDB database for E2E testing (NODE_ENV=test TEST_E2E=true).
• create collection indexes.
• generate entity changed broker messages. E.g. posts.entity.created, posts.entity.updated, posts.entity.removed

Loki logger for Moleculer microservices framework

It sends the Moleculer log messages to a Grafana Loki server directly. I'm using it to send logs from Fly.io moleculer app to Grafana Cloud.

For Kubernetes, I recommend to use Grafana Agent to send log messages because Agent adds K8s pod relevant labels to the messages.

Usage

// moleculer.config.js
