Defining models guide for typescript? (Error: "Property 'id' has no initializer and is not definitely assigned in the constructor.")

[mfbx9da4]

Hi, I'm new to watermelonDB but having trouble defining my model. There doesn't seem to be a typescript guide. For a start you need to enable experimentalDecorators in tsconfig which doesn't seem to be documented.

I am currently facing the error "Property 'id' has no initializer and is not definitely assigned in the constructor."

import { Model } from '@nozbe/watermelondb'
import { field, text, date } from '@nozbe/watermelondb/decorators'

export default class Me extends Model {
  static table = 'me'
  @text('id') id: string // ❌ throws error "Property 'id' has no initializer and is not definitely assigned in the constructor."
}

I found this typescript example https://github.com/Nozbe/WatermelonDB/blob/master/examples/typescript/ts-example.ts

Also the id column is a reserved special field https://nozbe.github.io/WatermelonDB/Schema.html#special-columns

Above example should look more like this

import { Model } from '@nozbe/watermelondb'
import { field, text, date } from '@nozbe/watermelondb/decorators'

export default class Me extends Model {
  static table = 'me'
  @text('firstName') firstName!: string | null
}

Reopening because there is no link to this example in the documentation. Also documentation for withObservables with typescript would be great too!

Closing for now to consolidate it to these issues:

@mfbx9da4 your contributions to docs would be highly appreciated
