Your First App

Let's build your first app which is a Todo list. First, we will create a folder for your project and prepare it.

$ mkdir -p ~/go/src/github.com/your_name/todo
$ cd ~/go/src/github.com/your_name/todo
$ uadmin prepare
[   OK   ]   Created: /home/abdullah/go/src/github.com/your_name/todo/models
[   OK   ]   Created: /home/abdullah/go/src/github.com/your_name/todo/api
[   OK   ]   Created: /home/abdullah/go/src/github.com/your_name/todo/views
[   OK   ]   Created: /home/abdullah/go/src/github.com/your_name/todo/media
[   OK   ]   Created: /home/abdullah/go/src/github.com/your_name/todo/static
[   OK   ]   Created: /home/abdullah/go/src/github.com/your_name/todo/templates

Now use your code editor to create main.go and put this code inside it.

package main

import (
	"github.com/uadmin/uadmin"
	"time"
)

type Todo struct {
	uadmin.Model
	Name        string
	Description string `uadmin:"html"`
	TargetDate  time.Time
	Progress    int `uadmin:"progress_bar"`
}

func main() {
	uadmin.Register(Todo{})
	uadmin.StartServer()
}

Now to run your code (Linux and Apple macOS):

$ go build; ./todo
