Create a async function from anything (promises, streams, objects and async functions)
npm install --save to-async-function
To convert any type of dataSources to async function
var toAsyncFunction = require('to-async-function');
var dataSource; // can be promises, streams, objects and async functions
var converted = toAsyncFunction(dataSource);
converted(function(err,data){
// will return when dataSource data is ready
// err: datasource reported errors if applicable
// data: data returned from
});To create a lib that can take any type of external data source promises, streams, etc... :
var toAsyncFunction = require('to-async-function');
// someLib first argument can be any type of data source!!!
function someLib(dataSource){
var dataSource = toAsyncFunction(dataSource);
dataSource(function(err,data){
// do something
});
}
