# Wray, faye client for Go
|
|
|
|
Wray is a client for the [Faye](http://faye.jcoglan.com) publish-subscribe messaging service by [James Coglan](https://twitter.com/jcoglan).
|
|
|
|
## Current status
|
|
|
|
In progress.
|
|
|
|
## Getting Started
|
|
|
|
Wray is only a client for Faye. You will need to setup a server using Ruby or Node.js first. Instructions that can be found on the [Faye project pages](http://faye.jcoglan.com/).
|
|
|
|
###Subscribing to channels
|
|
|
|
```
|
|
package main
|
|
|
|
import "github.com/pythonandchips/wray"
|
|
import "fmt"
|
|
|
|
func main() {
|
|
//register the types of transport you want available. Only long-polling is currently supported
|
|
wray.RegisterTransports([]gofaye.Transport{ &gofaye.HttpTransport{} })
|
|
|
|
//create a new client
|
|
client := wray.NewFayeClient("http://localhost:5000/faye")
|
|
|
|
//subscribe to the channels you want to listen to
|
|
client.Subscribe("/foo", false, func(message wray.Message) {
|
|
fmt.Println("-------------------------------------------")
|
|
fmt.Println(message.Data)
|
|
})
|
|
|
|
//wildcards can be used to subscribe to multipule channels
|
|
client.Subscribe("/foo/*", false, func(message wray.Message) {
|
|
fmt.Println("-------------------------------------------")
|
|
fmt.Println(message.Data)
|
|
})
|
|
|
|
//start listening on all subscribed channels and hold the process open
|
|
client.Listen()
|
|
}
|
|
```
|
|
|
|
###Publishing to channels
|
|
```
|
|
package main
|
|
|
|
import "github.com/pythonandchips/wray"
|
|
import "fmt"
|
|
|
|
func main() {
|
|
//register the types of transport you want available. Only long-polling is currently supported
|
|
wray.RegisterTransports([]wray.Transport{ &gofaye.HttpTransport{} })
|
|
|
|
//create a new client
|
|
client := wray.NewFayeClient("http://localhost:5000/faye")
|
|
|
|
params := map[string]interface{}{"hello": "from golang"}
|
|
|
|
//send message to server
|
|
client.Publish("/foo", params)
|
|
}
|
|
```
|
|
|
|
Simple examples are availabe in the examples folder.
|
|
|
|
##Future Work
|
|
There is still a lot to do to bring Wray in line with Faye functionality. This is a less than exhaustive list of work to be completed:-
|
|
|
|
- web socket support
|
|
- eventsource support
|
|
- logging
|
|
- middleware additions
|
|
- correctly handle disconnect and server down
|
|
- promises for subscription and publishing
|
|
- automated integrations test to ensure Wray continues to work with Faye
|

## Bugs/Features/Prase
|
|
|
|
It you find any bugs or have some feature requests please add an issue on the repository. Or if you just want to get in touch and tell me how awesome wray is you can get me on twitter @colin_gemmell or drop me an email at pythonandchips{at}gmail.com.

## Contributing to Wray
|
|
|
|
* Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
|
|
* Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
|
|
* Fork the project
|
|
* Start a feature/bugfix branch
|
|
* Commit and push until you are happy with your contribution
|
|
* Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
