Assignment 4

In this assignment, we finally get to work on frontend!!! You will be developing a simple songs list app which allows you to add and view songs.

Part 1: Song component

Create a component, Song, that represents a song in your playlist. It will be passed a prop called info that is an object which contains some information about the song. The fields in this object will be title, and artist.

You can test this component by importing the Song component in App.tsx and creating a component:

<Song info={{ title: 'Never Gonna Give You Up', artist: 'Rick Astley' }} />

Notice here that info acts a single prop. Song should expect only one prop, that being info.

Part 2: Adding songs

Create a component, Playlist, that contains all of the songs you've added. This will do the following:

  • Maintain a state containing a list of songs, which are objects containing the info about each song.
  • Have two input fields, one for title and one for artist.
  • Have a button which allows you to submit the new song and adds to the list.

Part 3: Adding Playlist to App.ts

Initialize your Playlist component in App.ts. This can be done by importing Playlist and creating a component:

<Playlist />

Part 4: Optional Challenge

Make it so that checking a box next to a song removes it from the Playlist.


Submit a zip file of everything in your project directory EXCEPT node_modules. You WILL lose points for including node_modules.
