Simple Todo App - Revel Typing CST Test
Simple Todo App — Revel Code
Demonstrates a simple Revel controller and view for managing Todo items using MVC architecture.
// app/controllers/todo.go
package controllers
import (
"github.com/revel/revel"
)
type Todo struct {
ID int
Title string
Completed bool
}
var todos []Todo
type TodoController struct {
*revel.Controller
}
func (c TodoController) Index() revel.Result {
return c.Render(todos)
}
func (c TodoController) Create(title string) revel.Result {
todo := Todo{ID: len(todos)+1, Title: title, Completed: false}
todos = append(todos, todo)
return c.Redirect(TodoController.Index)
}
// app/views/Todo/Index.html

Primary Use Cases
- ▸RESTful APIs and microservices
- ▸Web applications with MVC structure
- ▸High-performance backend services
- ▸Prototyping and rapid development
- ▸Cloud-native Go applications
Notable Features
- ▸MVC architecture for structured development
- ▸Hot code reloading for rapid development
- ▸Built-in routing with parameter handling
- ▸Validation and session management included
- ▸Integrated templating system for HTML rendering
Origin & Creator
Created by Rob Figueiredo and maintained by the Revel community since 2011.
Industrial Note
Revel is popular for Go developers who want a structured, Rails-like framework in Go, especially for building APIs and web services with high performance.
Quick Explain
- ▸Revel provides a full-stack framework with MVC architecture for Go applications.
- ▸Includes built-in routing, parameter parsing, validation, templating, and session management.
- ▸Supports hot code reloading to accelerate development iterations.
- ▸Highly modular and suitable for web APIs, web applications, and services.
- ▸Focuses on developer productivity and clear structure while leveraging Go’s concurrency and performance.
Core Features
- ▸Routing and controller dispatch
- ▸Validation for request parameters
- ▸Session and cookie management
- ▸Template rendering with Revel templates
- ▸Code reloading for development convenience
Learning Path
- ▸Learn Go programming language
- ▸Understand MVC architecture
- ▸Explore Revel routing, controllers, and templates
- ▸Build small APIs and scale complexity
- ▸Integrate database and middleware functionality
Practical Examples
- ▸Build a blog with CRUD operations
- ▸Develop a REST API for a mobile app
- ▸Implement authentication and role-based access
- ▸Create a web dashboard with templating and forms
- ▸Integrate third-party APIs for payment or notifications
Comparisons
- ▸Revel vs Gin: Revel full-stack MVC, Gin microframework, faster routing
- ▸Revel vs Echo: Revel full-featured, Echo minimal and lightweight
- ▸Revel vs Beego: Both full-featured, Revel simpler configuration
- ▸Revel vs Node.js/Express: Revel compiled, type-safe; Express dynamic JS
- ▸Revel vs Django: Revel uses Go; Django uses Python and larger ecosystem
Strengths
- ▸Quick setup and rapid development
- ▸Full-featured framework for Go without third-party dependencies
- ▸Type-safe and performant thanks to Go
- ▸Good integration with Go’s standard library and concurrency model
- ▸Clear project structure for scalable apps
Limitations
- ▸Smaller ecosystem than some other Go frameworks (e.g., Gin, Echo)
- ▸Less flexible than microframeworks for minimal apps
- ▸Hot code reload can be limited in production
- ▸Fewer tutorials and learning resources than larger frameworks
- ▸Templating engine less advanced than some alternatives
When NOT to Use
- ▸Teams unfamiliar with Go
- ▸Very lightweight microservices needing minimal framework
- ▸Projects requiring large ecosystem of third-party packages
- ▸Prototyping where Go compilation may slow iteration
- ▸When hot code reload is critical in production
