The minimal template creates the smallest possible runnable Mizu application. If you’re new to web development or Go, this is the best place to start. It contains just one file with about 20 lines of code, making it easy to understand exactly what happens when you run a web server.

​
When to Use This Template

Use the minimal template when:
  • Learning Mizu - Understand the basics without distractions
  • Quick experiments - Test an idea in minutes
  • Custom structure - You want to build your own project layout
  • Embedding examples - Need a simple example to share

​
What You Get

A single-file application with:
  • One Go file (main.go)
  • A basic route that returns “Hello”
  • A running server on port 8080
That’s it. No extra folders, no configuration files, just the essentials.

​
Quick Start

# Create the project
mizu new hello --template minimal

# Enter the project
cd hello

# Install dependencies
go mod tidy

# Run the server
mizu dev
Open http://localhost:8080 in your browser. You’ll see: 
Hello from hello

​
What the Code Looks Like

The entire application fits in one file: 
package main

import (
    "log"
    "github.com/go-mizu/mizu"
)

func main() {
    app := mizu.New()

    app.Get("/", func(c *mizu.Ctx) error {
        return c.Text(200, "Hello from minimal\n")
    })

    log.Println("listening on :8080")
    if err := app.Listen(":8080"); err != nil {
        log.Fatal(err)
    }
}
Let’s break this down:
  1. Create the app - mizu.New() creates a new Mizu application
  2. Add a route - app.Get("/", ...) handles GET requests to the root path
  3. Return a response - c.Text(200, "...") sends a plain text response
  4. Start the server - app.Listen(":8080") starts the HTTP server

​
Why Start Minimal?

​
Easy to Understand

With just 20 lines of code, you can see exactly what Mizu does:
  • Creates an HTTP server
  • Routes requests to handlers
  • Sends responses

​
Easy to Modify

Want to try something? Just edit the one file: 
// Add a JSON endpoint
app.Get("/api/user", func(c *mizu.Ctx) error {
    return c.JSON(200, map[string]string{
        "name": "Alice",
        "role": "admin",
    })
})

​
Easy to Grow

When you’re ready for more structure, you can:
  1. Add new files to the same directory
  2. Migrate to the api template
  3. Build your own custom structure

​
When to Upgrade

Consider switching to the api template when:
  • You have more than 3-4 routes
  • You need configuration management
  • Multiple developers are working on the project
  • You want feature-based organization
