Migration to v1

Dependencies

The lowest JavaScript version supported is now ES2023, which means Node 20 and later is supported. If you are using a platform that does not support ES2023, please upgrade.

TypeORM requires newer versions of the database client libraries.

Glob patterns are now handled by tinyglobby instead of glob. While tinyglobby is almost a drop-in replacement for glob, there might be certain cases in which the behavior is different.

MySQL / MariaDB

The connectorPackage option was removed, together with the support for the old mysql client. The only database client supported is now mysql2, which TypeORM will try to load by default. If you were using mysql in your project, simply replace it with mysql2.

Expo

Support for the legacy Expo SQLite driver has been removed. The legacy API was removed by Expo in SDK v52, so you'll need to use Expo SDK v52 or later with the modern async SQLite API.

hashing

Historically TypeORM used a non-standard SHA-1 implementation for hashing. This has been changed to use the built-in crypto module from Node.js.

For browser environments RandomGenerator.sha1 was fixed to the standard implementation.
