Inkwell - My simplistic journaling app?

Yeah, so, I just wanted to create a minimalistic website which allows people to journal as soon as they start. No sign-up, nothing liddat. Just start.

How I might run through this

General Framework

Frontend & Backend handled by Next DB handled by Mongo

API Routes

POST   /api/journal                      // Create journal & returns code

POST   /api/journal/[code]/entry         // Add new entry
PATCH  /api/journal/[code]/entry/[id]    // Edit entry
DELETE /api/journal/[code]/entry/[id]    // Delete entry
