Pattern for wrapping an Asynchronous JavaScript function to make it synchronous

Question

I\'m working with a JavaScript API where most of the functions are asynchronous. The API is the WebKit JavaScript Database API which is a binding to a subset of functionali

Answer 1

StratifiedJS allows you to do exactly that.

There's even an article on how to apply it on browser storage: http://onilabs.com/blog/stratifying-asynchronous-storage

And this is the Stratified JavaScript library it uses https://gist.github.com/613526

The example goes like:

var db = require("webdatabase").openDatabase("CandyDB", ...);
try {
  var kids = db.executeSql("SELECT * FROM kids").rows;
  db.executeSql("INSERT INTO kids (name) VALUES (:name);", [kids[0]]);
  alert("done");
} catch(e) {
  alert("something went wrong");
}

maybe a bit late, but the tech didn't exist back then ;)
