We need to start by implementing a data model for storing messages. The basic fields required are a unique ID, the username of the person sending the message, the namespace the message is sent to, their message, and finally a timestamp for when the message was sent. As messages are received or deleted, events must be emitted from the model so we can do the right thing on the web page.
This model implementation will be written for Sequelize. If you prefer a different storage solution, you can , by all means, re-implement the same API on other data storage systems.
Create a new file, models/messages-sequelize.mjs, containing the following:
import Sequelize from 'sequelize';import jsyaml from 'js-yaml'; import ...
