We now have enough implemented to run the application and see some real-time action.

As you did earlier, start the user information microservice in one window:

$ npm start

> user-auth-server@0.0.1 start /Users/david/chap09/users
> DEBUG=users:* PORT=3333 SEQUELIZE_CONNECT=sequelize-sqlite.yaml node --experimental-modules user-server

(node:11866) ExperimentalWarning: The ESM module loader is experimental.
  users:service User-Auth-Service listening at http://127.0.0.1:3333 +0ms

Then, in another window, start the Notes application:

$ npm start 
 
> notes@0.0.0 start /Users/david/chap09/notes 
> DEBUG=notes:* SEQUELIZE_CONNECT=models/sequelize-sqlite.yaml NOTES_MODEL=sequelize USER_SERVICE_URL=http://localhost:3333 node --experimental-modules ./app 
 
(node:11998) ExperimentalWarning: The ESM module loader is experimental. 
  notes:debug-INDEX Listening on port 3000 +0ms

Then, in a browser window, go to http://localhost:3000 and log in to the Notes application. To see the real-time effects, open multiple browser windows. If you can use Notes from multiple computers, then do that as well.

In one browser window, start creating and deleting notes, while leaving the other browser windows viewing the home page. Create a note, and it should show up immediately on the home page in the other browser windows. Delete a note and it should disappear immediately as well.
