The typeorm migration:run
command is used in the TypeORM library to run database migrations.
TypeORM is an Object-Relational Mapping (ORM) tool that allows developers to work with databases using object-oriented programming. It provides easy and efficient ways to manage database schema and handle migrations.
A migration in TypeORM represents a change in the database schema, such as creating or modifying tables, columns, indexes, etc. Migrations allow you to evolve your database schema over time without manually modifying the database.
The typeorm migration:run
command is executed in the command-line interface (CLI) to execute the pending or new migrations in the database. When you create a new migration using typeorm migration:create
, it generates a new migration file that contains a set of instructions to apply the necessary changes to the database schema.
When you run typeorm migration:run
, TypeORM reads these migration files and applies the pending migrations to the database. It connects to the database using the specified connection settings and executes the SQL statements required to bring the database schema up to date.
By running this command, you ensure that your database schema matches the latest version defined in the migration files, allowing your application to work with the updated schema.
