About

Description

A simple nodejs module for interacting with the Serf RPC protocol.

Author

Getting Started

Installation

npm install serf-rpc

Prerequisites

First run a serf agent as described in the serf docs.

Configuration

Simply require the serf-rpc module, instantiate a new Serf object, and call the .connect() method to start interacting with Serf's RPC protocol.

An optional object can be passed to the .connect([OPTIONS], fn) method to configure the RPC address. If ommitted, serf-rpc defaults to 127.0.0.1:7373. The object can be configured as follows:

 
var options = {
    rpc_host: "127.0.0.1",
    rpc_port: 7070
}
 
serf.connect(options, function(err){
    // interact with the RPC protocol
});

All operations are supported, but not rigorously tested yet.

For specific details about these operations, consult the official Serf RPC docs.

There are two more convenience functions, listen and log, easing the use of stream and monitor.

Examples

Example using the default RPC address, triggering a custom user event:

var SerfRPC = require("serf-rpc");
var serf = new SerfRPC();
 
serf.connect(function(err){
    if(err)
        throw err;
 
    serf.event({"Name": "deploy", "Payload": "4f33de567283e4a456539b8dc493ae8a853a93f6", "Coalesce": false}, function(err, response){
        if(err)
            throw err;
        else
            console.log("Triggered the event!");
    });
});
 
serf.listen("user", function(data, stop) {
    console.log('listen event!!', data);
    // serf.stop();
    // serf.leave(function(data) { console.log('leaving', data); });
});
 
serf.listen("query", function(data, stop) {
    console.log('query event!!', data);
    serf.respond({ ID: data.ID, Payload: "my response" }, function(err, data) {
        if(err)
            console.log("Error", err);
        else
            console.log("Response...\n", data);
 
    });
});
