With MariaDB, setting up replication requires activating the binary log in the primary database. Multi-master replication allows your application to write to multiple nodes. Distributed SQL enables unlimited scalability while keeping the strong consistency capabilities of relational databases.

Unexpected Discoveries in TypeORM 0.3.11

https://hackernoon.com

This article is about an unexpected discovery made while working with TypeORM, an Object-Relational Mapping (ORM) tool that is designed to work with TypeScript. The author upgraded the project to the latest version 0.3.11 and found some incompatible changes that they liked, some they were okay with, and others they didn't like. One of the things they liked was that the .findOne() or findOneBy() methods will no longer return undefined, instead they will return null. One of the things they were okay with was the new version's stricter requirement to pass the whole FindOptions object to the .find() method.
