Dynamic Database Connection with Go

This repository demonstrates how to create a dynamic database connection in a Go application by changing a single flag in the environment configuration. It includes implementations for both SQLite and CockroachDB.

Overview

In this project, we've implemented a dynamic database connection mechanism that allows developers to easily switch between SQLite and CockroachDB with minimal changes. This is achieved by utilizing environment variables to specify the desired database type.

Features

  • Dynamic database connection switching
  • SQLite and CockroachDB implementations
  • Clear separation of concerns for database interactions

Requirements

To run this project, you need the following:

  • Go programming language
  • go-sqlite3 package for SQLite support (optional)
  • CockroachDB (if using CockroachDB)

Getting Started

Follow these steps to set up and run the project:

  1. Clone the repository:

    git clone https://github.com/guptaaashutosh/Dynamic_Database_Connection_in_Go_SQLite_or_CockroachDB.git
cd Dynamic_Database_Connection_in_Go_SQLite_or_CockroachDB

  2. Install Dependencies:

    go mod tidy

    or,

  3. If using SQLite, install the go-sqlite3 package:

    go get github.com/mattn/go-sqlite3

  4. Install the CockroachDB driver for Go (refer to official documentation for specific instructions).

    https://www.cockroachlabs.com/docs/v24.1/install-cockroachdb-windows.html

  5. Create .config folder : create .env file inside it and configure as per .env.example file.

Dynamic_Database_Connection_in_Go_SQLite_or_CockroachDB/
├── .config/
│   └── .env
├── .env.example

  1. Set the DB_CONNECTION type environment variable to either "sqlite" or "cockroachdb" as per your requirement.

    The dynamic database connection is controlled by the DB_CONNECTION environment variable. Set this variable to sqlite or cockroachdb to choose the database type.

    DB_CONNECTION="sqlite"

  2. Run the Application:

go run cmd/main.go

Benefits:

  • Flexibility: Switch between databases based on your needs (development, testing, production).
  • Reusability: Database logic remains consistent regardless of the underlying database.
  • Maintainability: Code is easier to understand and maintain with a clear separation of concerns.

Further Considerations:

  • This example provides a basic structure. Adapt it to your specific database interactions and error handling.
  • Consider adding support for additional database types if needed.



This readme provides a starting point for creating a dynamic and flexible database connection system in your Go applications.
