nextalso

Flow control using event emitters.

NextAlso is an asynchronus flow control library for Node.js that uses event emitters to signal when a particular group of functions have all completed.

Currently NextAlso handles series and parallel execution of asynchronous functions. It also offers introspection into the current execution state by emitting events as each step is completed.

NextAlso uses method chaining to build expressive and explicit code that is easy to understand.

Examples

Execute functions in series

var fs = require("fs");
var NextAlso = require("nextalso");
var flow_control = new NextAlso();

flow_control.next(fs.readFile,['./test_file.txt'])
    .next(fs.readFile,['./test_file_2.txt'])
    .next(fs.readFile,['./test_file_3.txt'])
    .on("series_step",function(curr_results) {
        console.log("Series Step Fired -");
        console.log(curr_results);
    })
    .on("series_success",function(results) {
        console.log("Series completed successfully");
        console.log(resulte);
    });

ToDo

• Add logging lib
• Run both types grouped as chained
• Add debug events
• Waterfall results array through series
• Documentation
• Bind apply
• Warn if last param provided is fn
