socket.io-rpc-client

client library for a socket.io-rpc

All libraries are written in commonJS module style, so you need to use SystemJS loader to be able to use them in the browser. Browserify/webpack might work, if you set it up correctly, but might be a pain and you're probably will have to delve deep into the code. Angular.js lib contains special rpc-controller directive, which when compiled asynchronously loads server channel and instantiates classic angular controller when this channel is ready.

Usage

npm install socket.io-rpc-client for serverside usage

jspm install socket.io-rpc-client for clientside usage

then in Node.js:

var rpcClient = require('socket.io-rpc-client');
 
var rpc = rpcClient('http://localhost:8032');
//call to the server
rpc('plain')().then(function(ret) {
    console.log('plain returned ', ret);	//for test-utils/sample-server.js server prints out: plain returned 41
});
//expose some for the server to call
rpc.expose({
    fnOnClient: function() {
        console.log('called client method');
        return 42;
    },
    asyncOnClient: function() {
        return new Promise(function(resolve, reject) {
            setTimeout(function(){
                resolve('resolved after 40ms');
            }, 40);
        });
    },
    erroringMethod: function() {
        notdefined.error.will.propagate;
    }
});
 

in the browser:

var myChannel = require('rpc/test');   //CJS style require
//or
import {default as myChannel} from 'rpc/myChannel'; //ES6 style require
 
myChannel.getTime().then(t => { //calls getTime function on the server
    console.log("t", t);    //t is the serverside return value or serverside promise resolve value
});
