You want to easilly send messages, or notifications, to a web browser. You like Redis. You will love ESPubSub
Try it fastYou have Go installed and a Redis server is running (on the default port, without a password*)
git clone email@example.com:jweir/espubsub.git cd espubsub/examples go run server.go
Connect to http://localhost:8080/ with your browser
From the command line send Redis PUBLISH commands
redis-cli PUBLISH /events/alpha "Hello Alpha" redis-cli PUBLISH /events/beta "`date`"
How it works
ESPubSub is a Go HTTP Handler which allows clients to subscribe to channels via EventSource. Event Source is a simple browser api for reading from a long poll connection. Most common browsers, except IE and Android mobile, support it. See the poyfills below for unsupported browsers.
Channels receive data (strings) via a Redis PUBLISH command. ESPubSub will need to connect to a running Redis server.
Some EventSource polyfills (which I have not tried)
go get github.com/jweir/espubsub
The demo shows has one channel(
/events/*) using a glob to listen to multiple channels.
