Asynchronous Programming

 9 episodes latest episode published on 2016-04-20

In JavaScript, any operation involving the network or the file system is always asynchronous. Once you start implementing complex logic, coordinating I/O operations can become a challenge in Node.

This series will give you basic patterns and tools that will allow you to master and control asynchronous flow in Node. It covers the standard Callback pattern, queues, Event Emitters and Streams.

episode 1

The callback pattern, Chaining calls, Avoid callback hell, Generalizing error handling.

episode 2

Coordinating Parallel Calls

episode 3

Parallel Asynchronous Iteration, Parallel Asynchronous Mapping

episode 4

Serial Asynchronous Iteration, Serial Asynchronous Mapping, Limited Parallel Mapping

episode 5

async.series: running operations in series
async.waterfall: cascading results of series execution

episode 6

Using async.parallel; Coordinating results between async.parallel and async.waterfall.

episode 7

Asynchronous Iteration using async; iterating in parallel using async.each; Mapping in parallel using async.map; Iterating in series using async.eachSeries and async.mapSeries; Limiting the maximum amount of parallel requests.

episode 8

Using async.queue for building a local work queue.

episode 9

Managing errors, naming functions, using function hoisting, declaring functions in the lowest possible scope, using async.series, using async.waterfall, using function.bind.
