Take a sync function and make it async, passing its return value to a callback. Based on async#asyncify as module.
npm install async.wrapsync --save
If you want to use in the browser (powered by Browserify):
bower install async.wrapsync --save
and later link in your HTML:
<script src="bower_components/async.wrapsync/dist/async.wrapsync.js"></script>
var wrapSync = require('async.wrapsync');
var parse = wrapSync(JSON.parse);
parse('{\"foo\":bar}', function(err, result) {
// data is the result of parsing the text.
// If there was a parsing error, it would have been caught.
});
Take a sync function and make it async, passing its return value to a callback. This is useful for plugging sync functions into a waterfall, series, or other async functions. Any arguments passed to the generated function will be passed to the wrapped function (except for the final callback argument). Errors thrown will be passed to the callback
Arguments
