typeorm: Create an empty migration file.

typeorm

$ typeorm migration:create --name ${migration_name}

try on your machine

The command "typeorm migration:create --name ${migration_name}" is used in the TypeORM framework to generate a new database migration file with a specified name.

Here's a breakdown of what each part of the command does:

"typeorm": refers to the TypeORM CLI (Command Line Interface) tool which provides various commands for managing database migrations, entities, schemas, etc.
"migration:create": is a sub-command of the TypeORM CLI used to create a new database migration file.
"--name ${migration_name}": is an argument passed to the "migration:create" command, where "${migration_name}" should be replaced with the desired name for the migration file. This argument specifies the name of the migration file to be created.

When you run this command, it generates a new migration file with the provided name in a designated directory (according to your TypeORM configuration), usually in a "migrations" folder. This file will contain the necessary instructions for modifying the database schema, such as adding new tables, altering existing columns, or creating indexes. The migration file serves as a record of the changes made to the database and enables you to apply those changes to other environments or rollback the changes if needed.
