Modern Web Architecture with Templ and Fiber

Building modern web applications requires the right combination of tools and architectural patterns. In this post, we'll explore how Templ and Fiber work together to create fast, maintainable web applications.

Introduction to Templ

Templ is a language for writing HTML user interfaces in Go. It provides:

• Type safety

• Great IDE support

• Component composition

• No runtime overhead

Why Fiber?

Fiber is an Express-inspired web framework built on top of Fasthttp:

• **Fast**: Built on Fasthttp, the fastest HTTP engine for Go

• **Flexible**: Modular design with extensive middleware support

• **Developer Friendly**: Express-like API that's easy to learn

Project Structure

A well-organized project structure is crucial:

project/
├── internal/
│   ├── handlers/
│   ├── middleware/
│   └── services/
├── web/
│   ├── templates/
│   │   ├── components/
│   │   ├── layouts/
│   │   └── pages/
│   └── static/
└── cmd/
└── server/

Template Organization

Organize your templates by type:

• **Layouts**: Base page structures

• **Components**: Reusable UI elements

• **Pages**: Full page templates

This approach promotes reusability and maintainability.

Best Practices

1. Separation of Concerns: Keep business logic in services 2. Middleware: Use middleware for cross-cutting concerns 3. Error Handling: Implement proper error handling strategies 4. Testing: Write tests for your handlers and services

Building with Templ and Fiber gives you the performance of Go with the productivity of modern web development patterns.
