04: Parallel File Processing

Submission Instructions

• fork this repository & create a new branch for your work
• write all of your code in a directory named lab- + <your name> e.g. lab-susan
• push to your repository
• submit a pull request to this repository
• submit a link to your PR in canvas
• write a question and observation on canvas

Learning Objectives

• students will be able to create asynchronous programs using the node.js callback pattern
• students will be able to read, write, and encode binary data using the Buffer class
• students will be able to utilize the built-in fs module for basic file system I/O operations
• students will be able to use done (provided by mocha.js) for creating asynchronous tests

Resources

• fs module docs

Requirements

Configuration

• include the following:
  • README.md - contains documentation about your lab
  • .gitignore - contains a robust .gitignore file
  • .eslintrc - contains the provided .eslintrc file
  • .eslintignore - contains the provided .eslintignore file
  • lib/ - contains your modules
  • test/ - contains your unit tests
  • assets/ - contains the text files used by the program
  • index.js - contains main program file

Feature Tasks

• for this assignment you will need to read three files and console.log the first 8 bytes (in hex) of each file
• regardless of file size, all three files should be read and logged in the order 'one.txt', 'two.txt', 'three.txt'

Testing

• create a test that guarantees that the files are logged in the proper order
• create a test that checks for improper file paths

Documentation

• create a simple description of your project
• create a simple layer of documentation that describes how to use done in mocha callbacks
