terence410 / ts-datastore-orm Goto Github PK

I couldn't find any example for referencing an entity from another entity. Are relationships supported? Things like One-To-Many, Many-To-Many etc.

If not, is this something that is planned?

I have a use case to modify the entity date before insert. For example, generate a createdAt, lastModified. It would be easy for me to use hook to auto modify entity.

Curious if this is already possible with the current setup or if I can update the docs to do so?

I came across this problem:

• Can't create a constructor cause of this error "The 'this' context of type 'typeof MyEntity' is not assignable to method's 'this' of type 'typeof BaseEntity'.ts(2684)"

Should I set all properties as required and set a default empty state (empty string, 0, etc) or set all as nullable (with ?: operator)?

Or am I missing something about typescript? 🤔

Hi @terence410

first of all - a big thank you for writing and providing this package to the public. I know of the work behind an open source project - no matter of its size - a lot of work comes with the smallest projects.

The first things I've asked myself are the following:

• In the README.md you write "Simple class structure using typescript decorator. (Very similar to type-orm)" - so why don't you use TYPEORM?
• Do you plan to bring this project to a stable v1.0.0 ?
• Is there anything "known" that would you prevent from using it for production (beside the current 0.x version in general)?
• Is there a overview/documentation of the @ annotations somewhere?

Best regards

If I have something like

class A extends BaseEntity {
   @Column({ index: true })
  public id: string = '';
}

class B extends A {
  ...
}

@Entity({ kind: 'c' })
class C extends B {
...
}

it throws an error (C) Entity must define an id column.

I think this is caused by only checking first subclass and not all possible subclasses, here:

I know Google has Datastore and then what they call Firestore. I don't quite understand the difference, but is this library compatible with both?

I found this library really cool, but it is lacking of API documentation, and hard to know the purpose of each API, e.g., the meaning of generateId, _id.
