  2. ObjectDataProvider – data provider for simple in-memory storage (JS Object).

Installation

Use your favorite package manager. For example, yarn:

yarn add @rattus-orm/core

Important notes

If you are using Vite with TypeScript, make sure you have these settings in tsconfig.json:

{
  "compilerOptions": {
    // ...
    "useDefineForClassFields": true,
    "experimentalDecorators": true
  }
}

Also you should use this syntax for defining models:

class User extends Model {
  public static entity = 'users'

  @Str('')
  // public id: string - will not work, 
  // all fields of your models will be "null"
  declare id: string

Basic usage

import { Model, Uid, Str } from '@rattus-orm/core'
import { ObjectDataProvider } from '@rattus-orm/core/object-data-provider'
import { createDatabase } from '@rattus-orm/core/src'

class User extends Model {
  public static entity = 'user'

  @Uid()
  public id: string

  @Str()
  public email: string
}

const database = createDatabase({
  dataProvider: new ObjectDataProvider(),
  connection: 'entities'
}).start()

const userRepo = database.getRepository(User)
userRepo.save([{ id: '1', email: 'test@test.com' }, { id: '2', email: 'test2@test.com' }])

const found = userRepo.find('2')
