Project Modules

There are no modules declared in this project.

Run Async

npm tests dependencies

Utility method to run a function either synchronously or asynchronously using a series of common patterns. This is useful for library author accepting sync or async functions as parameter. runAsync will always run them as an async method, and normalize the multiple signature.

Installation

npm install --save run-async

Usage

Here's a simple example print the function results and three options a user can provide a function.

var runAsync = require('run-async');

var printAfter = function (func) {
  var cb = function (err, returnValue) {
    console.log(returnValue);
  };
  runAsync(func, cb)(/* arguments for func */);
};

Using this.async

printAfter(function () {
  var done = this.async();

  setTimeout(function () {
    done(null, 'done running with callback');
  }, 10);
});

Returning a promise

printAfter(function () {
  return new Promise(function (resolve, reject) {
    resolve('done running with promises');
  });
});

Synchronous function

printAfter(function () {
  return 'done running sync function';
});

runAsync.cb

runAsync.cb supports all the function types that runAsync does and additionally a traditional callback as the last argument signature:

var runAsync = require('run-async');

// IMPORTANT: The wrapped function must have a fixed number of parameters.
runAsync.cb(function(a, b, cb) {
  cb(null, a + b);
}, function(err, result) {
  console.log(result)
})(1, 2)

If your version of node support Promises natively (node >= 0.12), runAsync will return a promise. Example: runAsync(func)(arg1, arg2).then(cb)
