Tango

Tango is a micro & pluggable web framework for Go.

Current version: v0.6.2 Version History

Getting Started

To install Tango:

go get gitea.com/lunny/tango

A classic usage of Tango below:

package main

import (
    "errors"

    "gitea.com/lunny/tango"
)

type Action struct {
    tango.JSON
}

func (Action) Get() interface{} {
    if true {
        return map[string]string{
            "say": "Hello tango!",
        }
    }
    return errors.New("something error")
}

func main() {
    t := tango.Classic()
    t.Get("/", new(Action))
    t.Run()
}

Then visit http://localhost:8000 on your browser. You will get

{"say":"Hello tango!"}

If you change true after if to false, then you will get

{"err":"something error"}

This code will automatically convert returned map or error to a json because we has an embedded struct tango.JSON.
