1. Introduction
The HNG Boilerplate Golang Web project is a foundational template designed to streamline the development of web applications using the Go programming language. This boilerplate provides a structured framework that integrates essential components and best practices, allowing developers to focus on building features rather than setting up the groundwork.
The primary goal of this boilerplate is to offer a ready-to-use, scalable, and maintainable starting point for web applications. It addresses common requirements and setups in web development, including:
- Database Integration: Seamless connection and management of PostgreSQL databases.
- Configuration Management: Simplified handling of environment-specific settings.
- Routing: Efficient HTTP routing with support for middleware.
- Validation: Input validation using Go Playground's validator package.
- Logging: Centralized and configurable logging mechanism.
- Automated Testing: Pre-configured setup for unit and integration tests.
- Structured Project Layout: Organized directory structure for modular development.
- PostgreSQL Integration: Built-in support for PostgreSQL, including setup for migration and seeding.
- Configuration Management: Environment variable management to handle different configurations.
- HTTP Routing: Setup using a robust routing package with support for middlewares.
-
Validation: Input validation using the
validator.v10package. - Logging: Centralized logging to capture and format application logs.
- Automated Testing: Setup for writing and running tests using Go’s testing package.
This boilerplate serves as the backbone of your web application, providing essential functionalities and utilities. Here's a breakdown of what it does:
- Database Connection: Establishes a connection to the PostgreSQL database and handles database migrations.
- Configuration Loading: Loads configuration from environment variables, making it easy to switch between development, staging, and production environments.
- Routing: Sets up HTTP routes for handling requests and responses, supporting RESTful API development.
- Validation: Ensures that incoming data meets specified criteria before processing.
- Logging: Captures logs in a structured format for debugging and monitoring.
- Testing: Provides a framework for writing and running unit and integration tests to ensure code quality and reliability.
To start using this boilerplate, follow the setup instructions in the Getting Started section. This includes setting up your development environment, configuring PostgreSQL databases, and running the application.
By using this boilerplate, you can accelerate your development process, maintain a clean and organized codebase, and ensure your application adheres to best practices from the start.
