Tell HN: The way I do simple data management for new prototypes

Hi folks! I have huge success on a prototype of this approach:

- Store all data as json

- App loads: load full json on a client

- Something changes by user - change json locally and every 10 seconds save whole json to backend as a single json file

- also every 10 seconds load the updated json from backend to client.

Yes, I know, parallel access problems, lack of schema, lack of db, using file to store. But how much it makes life easier and speed ups development at start! I am in this over 20 years, and I like dumb stupid solutions applied properly. Duct taping forever!
