Go Web

Go-web is a framework for micro web app development. Build web apps as microservices.

Overview

Go-web is a tiny HTTP web server library which leverages go-micro to create micro web services as first class citizens in a microservice world. It wraps go-micro to give you service discovery, heartbeating and the ability to create web apps as microservices.

Features

Service Discovery
Heartbeating
Custom Handlers

Dependencies

Go-web makes use of go-micro which means it needs service discovery

See the go-micro for install instructions

For a quick start use consul

# install
brew install consul

# run
consul agent -dev

Usage

service := web.NewService(
	web.Name("example.com"),
)

service.HandleFunc("/foo", fooHandler)

if err := service.Init(); err != nil {
	log.Fatal(err)
}

if err := service.Run(); err != nil {
	log.Fatal(err)
}

Set Handler

You might have a preference for a HTTP handler, so use something else. This loses the ability to register endpoints in discovery but we'll fix that soon.

import "github.com/gorilla/mux"

r := mux.NewRouter()
r.HandleFunc("/", indexHandler)
r.HandleFunc("/objects/{object}", objectHandler)

service := web.NewService(
	web.Handler(r)
)

Call Service

Go-web includes a http.Client with a custom http.RoundTripper that uses service discovery

c := service.Client()

rsp, err := c.Get("http://example.com/foo")

This will lookup service discovery for the service example.com and route to one of the available nodes.
