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
<h1>Todo List</h1>
<ul>
{{range .todos}}
<li>{{.Title}}</li>
{{end}}
</ul>
<form action="/Todo/Create" method="post">
<input type="text" name="title">
<button type="submit">Add Todo</button>
</form>

Revel Language Guide

Revel is a high-productivity, full-featured web framework for Go (Golang), designed for rapid development of web applications with an MVC architecture, built-in routing, and code reloading.

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

Cheat Sheet

▸revel new myapp - create new project
▸revel run myapp - run local server
▸revel build myapp - build binary
▸Edit conf/routes - define routes
▸Edit app/controllers/ - create controllers

FAQ

▸Is Revel open-source? -> Yes, MIT license.
▸Can Revel be used in production? -> Yes, Go performance allows production-ready apps.
▸Does Revel support hot code reload? -> Yes, during development.
