Easy asynchronous programming with easy to handle results.
npm install node-asyncNeeded a library that would allow me to do a series of functions and wait for the result where I could then parse and move on with all the data.
So the idea is:
* Create a Array of functions I want executed.
* Wait for them execute
* Handle Results from the functions when they have been executed.
Based of https://github.com/CurriculumVitae/CV-Data-Service-Client/ that I wrote to help me with http-signature requests to the server.
``js
var async_block = require('node-async');
async_block(
[
{
name: 'get_twitter_feed',
task: function(params, callback) {
// Do http request etc.
callback null, data_from_twitter
}
},
{
name: 'get_facebook_feed',
task: function(params, callback) {
// Do http request etc.
callback null, data_from_facebook
}
},
{
name: 'perform_some_calculation',
task: function(params, callback) {
// Do http request etc.
callback 'Error while performing Calculation'
}
}
],
function(results) {
if(results.get_twitter_feed.result == true) {
console.log("From Twitter: " + results.get_twitter_feed.value);
} else {
// handle error
console.log("Error: " + results.get_twitter_feed.error)
}
if(results.get_facebook_feed.result == true) {
console.log("From Facebook: " + results.get_facebook_feed.value);
} else {
// handle error
console.log("Error: " + results.get_facebook_feed.error)
}
if(results.perform_some_calculation.result == true) {
// Do something nice
} else {
// Handle Error
console.log("Error: " + results.perform_some_calculation.error)
}
}
);
``
Will Produce:
From Twitter: {some data you got}
From Facebook: {some data you got}
Error: {The error we received.}
* Add some kind of timeout for the functions
* Create a Suite of Tests
* Add some more real world samples
