red.rpc

is a library which implements remote/inter-process procedure call using Redis as a transport.

A Detailed Example

process1.js

var RedRpc = require('red.rpc');
var red = new RedRpc({
    namespace: 'my.app'
});
// Declare a handler for numbers() method
red.handle({
    numbers: function(count) {
        var numbers = [];
        for (var i = 0; i < count; i++) {
            numbers.push(Math.random());
        }
        return numbers;
    },
    // Async procedures are possible with Promises
    format: function(number) {
        return new Promise(function(resolve) {
            setTimeout(function() {
                resolve('number = ' + number);
            }, 200);
        });
    }
});

process2.js

var RedRpc = require('red.rpc');
var red = new RedRpc({
    namespace: 'my.app'
});
// Declare a handler for sum() method
red.handle({
    sum: function(numbers) {
        return numbers.reduce(function(s, n) {
            return s + n;
        }, 0);
    }
});
    

process3.js

var RedRpc = require('red.rpc');
var red = new RedRpc({
    namespace: 'my.app'
});
// Obtain the API object
var api = red.define('sum', 'numbers', 'format');
api.numbers(100)
    .then(api.sum)
    .then(api.format)
    // Will log the formatted sum of 100 random numbers
    .then(function(string) {
        console.log(string);
    });
