Unknown database - [TypeOrmModule] Unable to connect to the database

Question

I'm writing my first project with Nestjs and I'm having trouble connecting to the database. I installed mysql and set up the connection. TypeOrm creates the database itself? or do i have to do it with mysql?

      username: 'root',
      password: 'password',
      database: 'my-database',
      entities: [User],

Answer 1

First you should create the my-database database in your mysql server.

The TypeOrmModule create only tables (in in first time.)

1. Create database in your mysql server: CREATE DATABASE myDatabase; (I recommend, use this format: myDatabase.)
2. Restart the Nestjs.

That's it!
