typing in progress

Objectives

You must follow the same principles as the first subject.

For this project you must create:

• A Typing in progress engine.

Instructions

A typing in progress engine is a way that people can see that a user is typing in real time. Allowing you to see the other user is replying or sending a message.

The typing in progress engine must work in real time! This meaning that if you start typing to a certain user this user will be able to see that you are typing.

This engine must have/display:

• A websocket to stablish the connection with both users
• An animation so that the user can see that you are typing, this animation should be smooth (no interruptions/janks) and just enough to draw attention for the user to see (user friendly)
• The name of the user that is typing
• Whenever the user stops typing or finishes the conversation, it should not display the animation

To help with the display of the typing in progress you can take a look on the js event list, mainly the Keyboard events and the Focus events
