add the ability to have some "undroppable" initial data about data HOT 4 CLOSED

Hey, @cloud-walker.

Please note that drop() is not meant for resetting the database state. It's designed to drop all the entities in the database.

If you wish to reset the state, consider combining drop with your seeding function:

import { drop } from '@mswjs/data'

function seed(db) {
  db.user.create({...})
  db.todo.create({...})
}

function resetDb(db) {
  drop(db)
  seed(db)
}

Would this approach work for your use case?

from data.

We've also discussed the reset API here, where the following API was suggested:

import { factory, snapshot } from '@mswjs/data'

const db = factory({...})
// seed your db...
db.user.create(...)

// Take the snapshot of database entities
// in this point of time.
const reset = snapshot(db)

// change the entities...
db.user.update(...)
db.todo.create(...)

// Reset to the exact state when
// the snapshot was taken.
reset()

There's been no investigating whether such API is possible with the current architecture, but if we ever adopt a reset API, it'd look similar to this.

Thats how I solved the issue with my current @mswjs/data experiment. But I think it's a waste of computation to do a reseed afterEach test.

BTW the snapshot proposal could solve the use case!

Closing this in favor of #86.
