Full Example

Basic Listeners

You can listen to create, update and delete events occuring in the database via Socket.io

Socket.io Namespace	Event Name	Arg 1	Arg 2	Caveats
/	entity_created	Entity Name	Full Entity	Only works when using EzBackend generated Routes
/	entity_updated	Entity Name	Full Entity	Only works when using EzBackend generated Routes
/	entity_deleted	Entity Name	Full Entity	Only works when using EzBackend generated Routes

Client Side (JS/TS)

You can connect and listen to the event updates with the following client side code (Assuming typescript)

import { io } from 'socket.io-client';

const socket = io('http://localhost:8000/'); //Or your backend url

socket.on('entity_created', (entityName, entity) => {
  console.log('Entity Name:', entityName);
  console.log('Entity:', entity);
});

socket.on('entity_updated', (entityName, entity) => {
  console.log('Entity Name:', entityName);
  console.log('Entity:', entity);
});

socket.on('entity_deleted', (entityName, entity) => {
  console.log('Entity Name:', entityName);
  console.log('Entity:', entity);
});

Authentication Client Side (JS/TS)

In order to send the authentication session, you can use the following

import { io } from 'socket.io-client';

const socket = io(
  'http://localhost:8000/', //Or your backend url
  {
    withCredentials: true,
  },
);

On the backend side, this populates req.user which allows you to manage authentication of users.
