Simple REST API - Martini Typing CST Test
Simple REST API — Martini Code
Demonstrates a simple Martini application with routes for listing and creating Todo items.
package main
import (
"github.com/go-martini/martini"
"net/http"
"encoding/json"
)
type Todo struct {
ID int `json:"id"`
Title string `json:"title"`
Completed bool `json:"completed"`
}
var todos []Todo
func main() {
m := martini.Classic()
m.Get("/todos", func(res http.ResponseWriter) {
json.NewEncoder(res).Encode(todos)
})
m.Post("/todos", func(req *http.Request, res http.ResponseWriter) {
var todo Todo
json.NewDecoder(req.Body).Decode(&todo)
todos = append(todos, todo)
res.WriteHeader(http.StatusCreated)
json.NewEncoder(res).Encode(todo)
})
m.Run()
}Martini Language Guide
Martini is a lightweight web framework for Go, designed for rapid development with simplicity and minimal boilerplate.
Primary Use Cases
- ▸RESTful APIs and JSON services
- ▸Small web applications and prototypes
- ▸Middleware-driven microservices
- ▸Rapid prototyping of Go applications
- ▸Educational and learning projects in Go
Notable Features
- ▸Lightweight and minimalistic
- ▸Middleware-driven design
- ▸Routing with parameters and patterns
- ▸Built-in dependency injection
- ▸Support for templates and static files
Origin & Creator
Created by Codegangsta (now known as Unrolled) in 2011, originally popularized in the Go community.
Industrial Note
Martini is favored for small to medium Go web services, APIs, and microservices where simplicity and rapid development outweigh large-scale ecosystem needs.
Quick Explain
- ▸Martini provides a simple, modular approach to building web applications using Go.
- ▸It uses a middleware-driven architecture, allowing handlers to be composed easily.
- ▸Supports routing, dependency injection, and basic HTTP handling.
- ▸Focuses on developer productivity and fast prototyping.
- ▸Lightweight and unopinionated, making it easy to integrate with other Go libraries.
Core Features
- ▸Routing and request handling
- ▸Handler functions with dependency injection
- ▸Support for middleware chains
- ▸Integration with templates (HTML, JSON)
- ▸Flexible request/response lifecycle
Learning Path
- ▸Week 1: Learn Go basics and net/http
- ▸Week 2: Understand Martini routing and handlers
- ▸Week 3: Middleware creation and usage
- ▸Week 4: Templates and static files
- ▸Week 5: Build a small CRUD project
Practical Examples
- ▸Simple REST API returning JSON
- ▸Static file server
- ▸CRUD web app with HTML templates
- ▸Middleware logging and authentication
- ▸Rapid prototype of microservices
Comparisons
- ▸Martini vs Gin -> Martini is simple and lightweight; Gin is faster and more feature-rich
- ▸Martini vs Echo -> Echo offers more middleware and modern features
- ▸Martini vs Revel -> Revel is heavier and more opinionated
- ▸Martini vs net/http -> Martini adds middleware and routing on top of Go standard library
- ▸Martini vs Fiber -> Fiber inspired by Express.js, optimized for speed; Martini is minimalistic
Strengths
- ▸Extremely lightweight with minimal overhead
- ▸Simple and easy to learn for Go developers
- ▸Highly modular via middleware
- ▸Quick prototyping and small apps
- ▸Clean and readable code structure
Limitations
- ▸No longer actively maintained (superseded by frameworks like Gin)
- ▸Limited ecosystem and plugins
- ▸Not suitable for large enterprise apps
- ▸Lacks advanced features like real-time Channels
- ▸Manual management needed for complex apps
When NOT to Use
- ▸High-performance or high-concurrency apps
- ▸Large-scale enterprise projects
- ▸Apps needing advanced features (auth, sessions, WebSockets)
- ▸Long-term maintenance projects
- ▸Projects requiring an active ecosystem
Cheat Sheet
- ▸go get github.com/go-martini/martini -> install Martini
- ▸martini.Classic() -> start a basic app
- ▸m.Get('/path', handler) -> define GET route
- ▸m.Post('/path', handler) -> define POST route
- ▸m.Run() -> start server
FAQ
- ▸Is Martini open-source? -> Yes, MIT License
- ▸Does Martini support middleware? -> Yes, middleware chain available
- ▸Can Martini handle high-concurrency apps? -> Limited, better with Gin
- ▸Is Martini actively maintained? -> No, mostly archived
- ▸Does Martini support templates? -> Yes, using Go templates
30-Day Skill Plan
- ▸Master Go standard library
- ▸Understand HTTP request/response lifecycle
- ▸Practice middleware design
- ▸Integrate databases with handlers
- ▸Refactor and modularize small projects
Final Summary
- ▸Martini is a lightweight and minimalistic Go web framework.
- ▸Provides routing, middleware, and dependency injection.
- ▸Ideal for small projects and rapid prototyping.
- ▸Not suitable for high-performance or enterprise-scale applications.
- ▸Superseded by faster and more modern Go frameworks like Gin and Echo.
Project Structure
- ▸main.go - entry point
- ▸routes/ - route definitions (optional)
- ▸handlers/ - request handlers
- ▸templates/ - HTML templates (optional)
- ▸static/ - CSS, JS, images
Monetization
- ▸Open-source, MIT License
- ▸Consulting for small Go services
- ▸Rapid prototyping for startups
- ▸Internal tooling for enterprises
- ▸Training and learning projects
Productivity Tips
- ▸Use middleware for logging and recovery
- ▸Keep handlers small and modular
- ▸Use Go templates for HTML
- ▸Leverage Go concurrency for lightweight tasks
- ▸Automate tests and builds
Basic Concepts
- ▸Router - defines HTTP routes and handlers
- ▸Handler - function executed per request
- ▸Middleware - pre/post processing logic
- ▸Context - manages request-scoped data and DI
- ▸ResponseWriter - sends HTTP responses
