golang server sent events (sse) todo example

This example was inspired by golang-html5-sse-example and TodoMVC. It uses knockout.js for the UI and mongodb for storage. It's a little different than the other TodoMVC examples in that it adds SSE capabilities to synchronize the todo list.

Up and Running

Install Dependencies

Install golang

Install git and bazaar

sudo apt-get install git bzr

Install mongodb

Install mgo, the mongodb driver for golang

mkdir -p ~/Go/vendor
export GOPATH=~/Go/vendor
go get gopkg.in/mgo.v2

Clone this repository to your local filesystem

git clone https://github.com/rwynn/golang-sse-todo.git

Start the Servers

Start the mongo server if it's not already running

sudo mongod -f /etc/mongodb.conf

Run the Go server (assumes that $GOPATH already includes ~/Go/vendor to find mgo)

cd /path/to/golang-sse-todo
export GOPATH=$GOPATH:`pwd`
go run todo.go

Create some Todos

Open 2 instances of your browser side by side (your browser should support html5 EventSource). Navigate each browser to http://localhost:9080/static/

Start typing todo items in one of the browser instances. The todo should be listed and dynamically updated in both browser instances. Pressing return/enter will allow you to start entering a new todo.

Stop the Go server by pressing Control-c in the terminal.
