Exercise #5: Watch Party

10 points

DUE: Thursday, February 16 by 5:30pm

Instructions

For this exercise, we will build a group chat web application with asynchronous Javascript and a REST API written in Python with Flask. Watch Party is a public group chat program. You have here a skeleton of the app, including signup, login, and logout flows. Take the Watch Party UI here and serve it using server-side code written in the latest stable version of Python and the Flask web application framework. You may want to read the Flask Quickstart Guide.

Launch the app by running flask run on the command line from your Exercise 5 directory. I recommend running flask run --reload, which will make the server automatically load changes to your python files.

Your task will be to implement a REST API for some of the Watch Party's functions, and client-side Javascript code that consumes that API. Though the exercise is designed to only require changes to script.js and app.py, you may make any adjustments to any other files you feel would be helpful.

Remember to include in your submission any classmates you collaborated with and any materials you consulted. Watch Party (though it has somewhat different requirements) is inspired by yap.chat.

Rubric

  • room.html currently has a number of dummy messages to demonstrate styling. Implement an API endpoint that accepts and returns JSON and that returns all the messages in a chat room. [1 point]
  • API endpoints require a valid API key in the request header. They do not use username/password, and they do not send the API key in the request body.
  • Write Javascript code that uses fetch to retrieve that list of messages. [1 point]
  • When a chat room page first loads, clear any sample messages out of the chat histoy. [1 point]
  • Create HTML elements for the messages retreived from the API using document.createElement. Do not write HTML strings. [1 point]
  • While in a room, check the messages endpoint every 100 ms and add any new messages to the chat history.[1 point]
  • Implement an API endpoint to allow users to post messages in a chat room. On all queries, pass variable parts to the SQL statement by using a question mark in the statement and pass in the arguments as a list, as described in the Flask docs [1 point]
  • Default usernames, passwords, and room names are set automatically. Implement three API endpoints that accept and return JSON and that allow a user to change their username, their password, and the name of the room they are in. [1 point]
  • Javascript code that uses fetch to allow a user to update their username or password without reloading the page. [1 point]
  • Javascript code that uses fetch to allow a user to update the name of a room without reloading the page. [1 point]
