Week 1 Challenge - Parallel Asynchronous recursiveReaddir

This exercise is to build an API for recursively listing the files in a directory in parallel, or in other words, a recursive ls. The purpose of this exercise is to practice control-flow for asynchronous IO, specifically running operations in serial and parallel. Additionally, this exercise will explore the fs filesystem module from core.

IMPORTANT: Review the Control-flow Guide to familiarize yourself with async/await. Ignore Promise and callbacks for now.

Getting Started

The checkpoints below should be implemented as pairs. In pair programming, there are two roles: supervisor and driver.

Creating the Proxy Server

The pre-work incorporates a few steps:

1. Setup your Node.js environment
2. Complete the introductory NodeSchool.io Workshoppers
3. Build a proxy server and setup logging
4. Develop a command-line interface (CLI) to configure the server
5. Submit the project for review via Github
6. Extend your proxy server with additional functions

Proxy Server

This is a Proxy Server for Node.js submitted as the pre-work requirement for the Node.js Bootcamp.

Time spent: 3h

Completed:

• Required: Requests to port 8000 are echoed back with the same HTTP headers and body
• Required: Requests/reponses are proxied to/from the destination server

Week 1 - Command Line Interfaces (CLIs)

This week, we'll ensure our environments are properly setup and walk through the fundamentals of the node.js runtime with a focus on asynchronous programming, control-flow and IO. We'll keep things simple by sticking primarily to the filesystem, stdin and stdout to write basic CLIs like an asynchronous recursive readdir CLI.

Assignment

Assignment 1: Filesystem CLIs due at 10:00pm

This week, we'll build a collection of common filesystem CLIs. The purpose of this project is to develop a basic understanding of control-flow and the node.js runtime, module system and ascyhronous APIs.
