1. Create a django application.
2. Create a vue application.
3. Throw in html.
4. Create a message model.
5. Write an API in DRF .
6. Then use vue to make requests to the server and pull messages.
It is recommended to create a separate environment for each project.
At the expense of the database, use sqlite, don't worry.

Answer 2

I use the same bundle, only NodeJS - raised WebSocketServer.
And when a request for NodeJS comes in, VueJS through axios (you can use vue-resource) makes a request through DRF.
What is the advantage of my method: the query goes to the database only when a message arrives, and not every 10 seconds.
PS Imagine every 10 seconds 15'000 users make 15'000 requests. Doubtful pleasure.
