CPNT 262 Assignment 4 - Node command line app

In this assignment, you will create a simple Node app of your choice that will:

• accept at least two arguments from the command line;
• log three different responses to the console;
• incorporate a third party npm package.

The arguments, responses and npm package are up to you. Use your imagination! The goal is to fulfill the criteria below.

Note: you CANNOT use app examples shown in class:

• Tip Calculator
• Adding Machine
• Simple Calculator
• Greeting App

Criteria

This assignment will be marked out of 10 points. Each of the following requirements are worth 2 points each:

1. Command Line Arguments

• App must accept at least two command line arguments using the process.argv array.
• Both arguments must be used to determine the Logged Response (see below).
• App may also use the yargs package as your third-party npm package (see below).

2. Logged Response

• Responses must be logged to the console using console.log().
• App must support at least three distinct responses that depend on the Command Line Arguments above.
• App must respond gracefully when:
  • No arguments are passed;
  • Not enough arguments are passed;
  • Arguments are not the expected value type (i.e. values are validated).

3. npm Project Setup

• A valid package.json file is present:
  • name is set to cpnt262-a4;
  • main is set to app.js;
  • author is set to your name;
  • dependencies includes the Third-party npm Package below.
• A project .gitignore file is included and excludes the node_modules directory.
• The node_modules directory is not present in your repo, nor the ZIP submitted to Brightspace.

4. Third-party npm Package

• At least one third-party npm package (of your choice) must be incorporated into your App.
• Package must:
  • be included as a dependency in package.json;
  • NOT be included in a node_modules directory;
  • contribute in some way to the Logged Responses, either directly or indirectly.

5. Instructions and Documentation

Instructions and documentation must be included in a README.md file to help your instructor mark your assignment:

• A short (one sentence) description of what your App does (it does not have to be useful);
• Include three example commands that can be copy and pasted (note: each of these three commands should return different responses);
• Describe (be short and concise) how you used your third-party app and reference a line number where an example can be found;
• Attributions for:
  • code that is not yours;
  • help you received from any classmates;
  • the Third-party npm Package you used.

• Apps that does not operate after your instructor runs the command npm install;
• Violations of coding conventions (indentation, naming, etc);
• Extra time it takes for your instructor to run/debug your App (for example: file permissions errors if App writes to the database);
• Not following the Submission Requirements.
