A NodeJS API for HAProxy. This can be used to expose a REST API or to control haproxy from Javascript.
This project is not maintained anymore. If you want to get ownership, please contact me. Otherwise, you can have a look at haproxy-sdk and haproxy-api
var HAApi= require('ha-api'),
haapi = new HAApi({
socket: {
host : 'haproxy.address',
port : 1234
},
apiPort : 1111
})
HAProxy must open its configuration socket. This is done in the haproxy.cfg file using the followinf syntax:
TCP socket
stats socket ipv4@0.0.0.0:1234 level admin
Local domain UNIX socket
stats socket /tmp/haproxy.sock level admin
socket : HAProxy socket information. It can be either a TCP socket { host : 'haproxy.address', port : 1234 } or a UNIX local socket : { socket : '/tmp/haproxy.sock' }
app : optional express() instance. If provided, API methods will be added to this isntance. If not, a new express() will be created.
apiPort : TCP port to expose the REST API.
