Unable to load entities after update to version 0.3.12

[heldercunha]

Issue description

After update the typeorm 0.3.11 to version 0.3.12, entities classes cannot be found by path

Expected Behavior

Found all entities classes to load.

All classes found using provided glob pattern "D:\projects\app\src\entities\**\*.entity{.ts,.js}"

Actual Behavior

No entities classes found

No classes were found using the provided glob pattern: "D:\projects\app\src\entities\**\*.entity{.ts,.js}"

Steps to reproduce

Create a new DataSource, configure the DataSource connection, and the entities path.

    const postgresqlDataSource: DataSource = new DataSource({
        type: 'postgres',
        applicationName: 'app,
        host: postgreSQL.host,
        port: postgreSQL.port,
        database: postgreSQL.database,
        username: postgreSQL.username,
        password: postgreSQL.password,
        useUTC: true,
        poolSize: 10,
        connectTimeoutMS: 0,
        dropSchema: false,
        synchronize: false,
        migrationsRun: false,
        uuidExtension: 'uuid-ossp',
        logging: true,
        entities: [join(__dirname, './entities/**/*.entity{.ts,.js}')],
        subscribers: [],
        migrations: [],
    });

Are you willing to resolve this issue by submitting a Pull Request?

Yes, I have the time, but I don't know how to start. I would need guidance.

I've encountered this bug as well. I debugged into TypeORM and figured out that it was caused by the update of package glob, which is responsible for resolving the glob pattern used in the entity configuration.
As mentioned in this issue, the update breaks its compatibility on Windows, interpreting "\" as an escape character instead of a valid path separator.
This is the origin of this bug, but another point also contributes to this problem: TypeORM will normalize the path before passing it to glob (util/DirectoryExportedClassesLoader), which will replace all forward slashes with backslashes (because backslash is the primary path separator on Windows). That's why this bug will still occur even if you use forward slashes in your config file.

Some temporary solutions before a new patch version release:

• Downgrade to 0.3.11
• Manually import all entity classes and list them in the config file

Thanks @truemogician for investigation and detailed explanation.

проблема не только с сущностями но и с миграциями естественно, тоже не ищет

This also causes problems with loading migrations. About a soon release of the fix I would be very happy @pleerock ✌️ ☺️

[potier97]

Esto también se convierte en un problema si contamos con distintos ambientes (develop, stage, preprod, production), nos obliga a tener un archivo de migración por cada ambiente, si seria bueno una solución para esto

Is that feature not anyway deprecated or did i read wrong in the past changelogs?

[amjmhs]

0.3.13 fixes the issue for me and all migrations are found again. Thank you 🙏

Is that feature not anyway deprecated or did i read wrong in the past changelogs?

Yes, it is deprecated and not recommended to be used anymore. From the changelog:

DEPRECATIONS

• entities, migrations, subscribers options inside DataSourceOptions accepting string directories support is deprecated. You'll be only able to pass entity references in the future versions.

Which means, as I understand it, that from version 0.3.0 we need to list real entities in the array of entities and not a list of string paths to files:

import { MyEntity1 } from '@/path/to/MyEntity1'
import { MyEntity2 } from '@/path/to/MyEntity2'

new DataSource({
  entities: [MyEntity1, MyEntity2]
})
