chitchat

chitchat

A basic websocket-based chat service written in Go

Building

You need the following:

• Go
• Node
• NPM
• Bower
• Gulp

# Build our application
go get
go build

# Install assets
npm install
bower install

# Compile/minify assets
gulp

Running

With all defaults:

# Development mode
./chitchat

# Production mode
./chitchat --production

There are flags that you can pass, and will probably have to at least for your database.

You can view them all in flags.go or pass the --help flag to the application.

./chitchat --help

Tasks

Conceptually, the service should have five high-level capabilties:

• Connect
• Login
• Send Message
• Receive Message (push)
• Fetch Message History

Service requirements

• Connect to server

  The server should accept HTTP requests and upgrade them to websocket connections.

• "Login" with username

  A connected client should be able to authenticate with a given username. Don't worry about passwords at this point.

• Send Message to another username

  An authenticated connection should be able to send a text message to a given username. Messages should be persisted to a database.

• Receive Messages in realtime

  An authenticated connection should receive messages sent to its authenticated username. (What happens if multiple connections are authenticated with the same username?)

• Fetch Message History

  Mobile apps go offline and online all the time. An authenticated connection should be able to fetch missed messages.
