[Feature Request] attributes of 'number' type, enumerated 'as const'. about electrodb HOT 7 OPEN

@tywalch I tried using CustomAttributeType per your example but I'm getting this error:

Exported variable 'MyEntity' has or is using name 'OpaquePrimitiveSymbol' from external module "/Users/me/Projects/app/node_modules/electrodb/index" but cannot be named.

Any ideas? Your playground link works fine though.

Typescript version: 4.9.4 (latest)
ElectrodDB version: 2.3.5 (latest)

Hey, this came up in a side project of mine, no further progress beyond my last comment 🙂

For this, I would recommend use of CustomAttributeType to accomplish this -- would that work in your case? I'd imagine given your example it'd be able to accomplish your needs and has the benefit of already being available.

My hesitancy around numeric enums is that Electro can't really enforce what values could end up in the table, when you consider atomic mutations like add and subtract, etc. A formal numeric enum might give users the impression that'd be handled by the library somehow.

Got it. The following seems (at first glance) to work:

{
  attributes: {
    ratingNumStars: {
      type: CustomAttributeType<0 | 1 | 2 | 3 | 4 | 5>('number'),
      default: 0
    }
  }
}

although, for what it's worth, putting an invalid value in for the default (e.g. 6) doesn't cause a type error.

Could it be your version of TypeScript? Here is an example in the playground, which uses the latest version of TypeScript:
