LAB 03

Notes for grading:

• I completed all of Part 1 - Read and Write to a File.
• I started Part 2 - Reading Multiple Files.
  • I only completed this up to Task 1: Fix the broken code.
  • I figured out Task 1 pretty quickly, but spent a lot of time trying to get the first test to pass (there was an issue with the mock included in the demo code).
• Still working on getting JSdocs up and running.

Modules - Part 1

edit-file.js

Exported Values and Methods

Using the node CLI (see instruction below), reads, adds to, and reads a file again. Nested node filesystem (fs.) functions accomplish this and have the results logged to the console.

Modules - Part 2

Exported Values and Methods

reader.readAll([...files], callback) -> number

Given an array of files and a callback error handler function, reads the file name and contents of each file. The callback function takes (err, data). If there is an error, the error handler will run.

Setup

.env requirements

• npm i - install dependencies

Running the app (with the node CLI)

• node edit-file files/test.txt - Reads a file, appends a random word to that file, reads the file again
• node index.js files/1.txt files/2.txt files/3.txt - Reads the file names and contents of 3 files

Tests

• npm test to run tests
• Assertions: to do
• Assertions to be made: to do
