Build Status Coverage Status Dependency Status

Streams for socket.io. Also works with mesh.

Basic example

var mesh = require("mesh");
var loki = require("mesh-loki");
var io   = require("mesh-socket.io");
 
var bus = mesh.tailable(loki());
 
// setup socket io - take all remote ops and pass
// to the bus
var iobus = mesh.reject("load", io({
  host: "http://localhost"
}, bus));
 
// pipe all operations on bus to socket.io
bus(mesh.op("tail")).pipe(mesh.open(iobus));
 
// insert data into the DB. Should get broadcasted
// to socket.io
bus(mesh.op("insert", {
  collection: "people"
  data: {
    name: "Shrek"
  }
}));

server configuration

Server configuration is pretty easy to setup. Just re-broadcast incomming operations.

var io = require("socket.io");
var server = io(80);
server.on("connection", function(connection) {
 
  // note that "operation" is the channel that the client is
  // publishing / subscribing to
  connection.on("operation", function(operation) {
 
    // re-broadcast to other clients
    connection.broadcast.emit("operation", operation);
  });
});

db(options, bus)

creates a new socket.io streamer.

  • options
    • host - socket.io server host
    • channel - channel to subscribe to. Default is operation.
  • bus - bus to pass remote calls to
var iodb = io({
  host: "http://localhost",
  channel: "myOperationsChannel"
})

stream.Readable db(operationName, options)

Broadcasts a new operation. This can be anything.

stream.Readable db(tail, filter)

Tails a remote operation.

 
// tail all operations
db(mesh.op("tail")).on("data", function() {
 
});
 
// tail only insert operations
db(mesh.op("tail", { name: "insert" })).on("data", function() {
 
});
 
// tail only operations on people collection
db(mesh.op("tail", { collection: "people" })).on("data", function() {
 
});
