Mothership

Mothership is a music player interface for MPD, optimised for browsing your music collection in its original directory structure.

Mothership is built with Go, AngularJS & WebSockets providing a snappy, real-time user experience. All connected clients keep the UI in sync with the player state.

Mothership is cross-platform & extremely portable, building to a single, self-contained binary with no external dependencies other than an MPD server to point it to.

Build

To build the Mothership binary, install the development prerequisites, then:

(cd frontend && grunt build)
go-bindata frontend.go -prefix "frontend/dist/" frontend/dist/...
go build

Cross-compilation is achieved by modifying the go build command. For example:

• Build for a Raspberry Pi 2: GOOS=linux GOARM=7 GOARCH=arm go build
• Build for a Raspberry Pi 1: GOOS=linux GOARM=6 GOARCH=arm go build
• Build for linux/386: GOOS=linux GOARCH=386 go build
• Build for darwin/386: GOOS=darwin GOARCH=386 go build
• Build for windows/386: GOOS=windows GOARCH=386 go build

Run

Firstly, build Mothership, then:

mothership -mpdaddr=music:6600 -port :8080
open localhost:8080

Modify -mpdaddr to point to the host:port (or ip:port) of your running MPD server.

Deploy

Deployment is simple, transfer the binary & run it. A complete example is provided below:

• Example server configuration (using Ansible)
• Example deploy script

Develop

While developing, the assets are not packaged into a binary, this allows us to make front-end changes without rebuilding the back-end.

Install the development prerequisites, then:

(cd frontend && grunt)
go build && mothership -mpdaddr=music:6600 -port :8080
open localhost:8080

grunt watches for changes and runs all front-end tests.

go test ./... runs all the back-end tests, or run a single package with a command like (cd handlers && go test).

Development prerequisites

• Go
• Node.js & npm
• go get github.com/jteeuwen/go-bindata/...
• (cd frontend && npm install)

Extras

• Add an LCD with Flashlight
• Build a multi-room audio system with Raspberry Pis, MPD & PulseAudio:
  • Server
  • Clients
