Your app is relying on a Realm global, which will be removed in realm-js v13, please update your code to ensure you import Realm

How frequently does the bug occur?

Always

Description

I wanted to implement a Singleton class for Realm to ensure reusability throughout the application. Creating a separate instance for each component doesn't seem practical.

Stacktrace & log output

WARN  Your app is relying on a Realm global, which will be removed in realm-js v13, please update your code to ensure you import Realm:

 import Realm from "realm"; // For ES Modules
 const Realm = require("realm"); // For CommonJS

 To determine where, put this in the top of your index file:
 import Realm from "realm";
 Realm.flags.THROW_ON_GLOBAL_REALM = true

Can you reproduce the bug?

Always

Reproduction Steps

1. Create a file that holds Realm instance

const realm = new Realm({ schema: [TestSchema] })

export default realm

1. Import this from your component
2. Get the warning

Please try setting the THROW_ON_GLOBAL_REALM as outlined here, to figure out where you're using Realm without an import:

import { flags } from "realm";
flags.THROW_ON_GLOBAL_REALM = true;

[buster95]

this is because you are using Realm without import check your Schemas and every part you use Realm.

for example you can define a schema in this way

export class PersonSchema extends Realm.Object<Person> {
  name!: string
  age?: number

  static schema: Realm.ObjectSchema = {
    name: 'Person',
    properties: {
      name: 'string',
      age: 'int?',
    },
  }
}

but the right way is this

import Realm from 'realm' // <-- check yours imports

export class PersonSchema extends Realm.Object<Person> {
  name!: string
  age?: number

  static schema: Realm.ObjectSchema = {
    name: 'Person',
    properties: {
      name: 'string',
      age: 'int?',
    },
  }
}
