domain

Documentation

Overview

Package domain provides preconfigured, ready-to-use service clients for external systems such as databases, caches, and third-party services.

Each subpackage under domain represents a specific integration (e.g. MongoDB, Upstash, etc.) and exposes a client that can be easily instantiated and used without additional setup complexity.

Philosophy

The goal of this package is to:

• Centralize external service integrations
• Provide consistent and minimal client initialization
• Reduce boilerplate when working with infrastructure services

Structure

Each subdirectory:

• Targets a specific service or provider
• Exposes a client with sensible defaults
• Is designed to be plug-and-play within applications

Example:

domain/mongo   → MongoDB client
domain/upstash → Upstash Redis client

Usage

Import the desired subpackage and create the client:

client := mongo.New(...)

Notes

• Clients are intended to be lightweight and composable
• Configuration is typically injected from higher-level packages
• Each client is isolated, making it easy to swap implementations
• Documentations for the subdirectories is omitted
