HackYourFuture Node.js Week 2 - Homework

Assignment

These are the specs for this week's assignment:

• Write a Node.js command line application
• The user must be able to run the file using node index.js or node . in the project directory
• There must be a help section that lists all the commands and a short description for each of them
• The user must be able to add, remove and list to-dos.
• The user must be able to remove all to-dos at once.

The following commands must be present:

No command or help

Shows help section

node index.js

or

node index.js help

list

Shows current to-dos, or shows an appropriate text if there are no to-dos

node index.js list

add

Adds a to-do item. All the words behind add are entered as 1 to-do item to the list.

node index.js add "Buy groceries"

remove

Removes a to-do item by its 1-base index, e.g. to remove second item, execute:

node index.js remove 2

reset

Removes all to-do items from the list:

node index.js reset

Bonus assignment

• Use JSON to store to-dos
• Split each action (i.e. read, write, etc.) into a separate file
• Use commander library to implement command line interface

Add following commands:

update

Updates a to-do item with new text:

node index.js update 3 "Brush teeth"

Things to consider

• What representation you use in your file (CSV, TSV, JSON, etc).
• Handle edge cases, i.e. control what happens if user enters unexpected input, e.g. remove -100.
