Logger Service

A simple and efficient logging microservice that listens to a RabbitMQ queue and stores logs in a database. Ideal for use in a microservice or full-stack application architecture.

---

Features

• Listens to a RabbitMQ queue for incoming HTTP request logs
• Buffers logs and performs bulk inserts into the database
• Reconnection logic to handle RabbitMQ disconnects
• Graceful shutdown support

---

Tech Stack

• Bun.js
• TypeScript
• RabbitMQ (via amqplib)
• Drizzle ORM (for database operations)
• SQlite ( you can use any DB you want , codebase if easy )

Setup Instructions

1. Clone the repository

git clone https://github.com/pradeepbgs/loggers.git
cd logger-service

2. Install dependencies

cd logger_dieseljs
bun install

3. Setup environment variables

Create a .env file in the root directory:

AMQBHOST=amqp://localhost
LOGS_QUEUE=request-logs
DATABASE_URL=your_postgres_database_url
or DB_FILE_NAME=your_sqlite_filename you want to give

4. Migrate the schema to sqlite

bun run generate
bun run migrate

5. Start the service

bun run dev

The service will connect to RabbitMQ, wait for messages on the request-logs queue, and insert logs in batches into the database.

Notes

• Make sure RabbitMQ and PostgreSQL are running and accessible.
• Customize BULK_INSERT_THRESHOLD in code to control batch size.
• You can customize startConsuming code base and can make it save bulk data in a given time with setTimeout.
