getConnection/getRepository typeorm is deprecated

Question

i get error for import typeOrm

anyone know why my typeorm package is deprecated?

Answer 1

Connection, ConnectionOptions are deprecated, new names to use are: DataSource and DataSourceOptions. To create the same connection you had before use a new syntax: new DataSource({ /*...*/ }).

createConnection(), createConnections() are deprecated, since Connection is called DataSource now, to create a connection and connect to the database simply do:

server.ts

export const appDataSource = new DataSource({
   // ... options
});

const main = async () => {
    console.time('main');
    await appDataSource.initialize();
};

main().catch(err => {
    console.error(err);
    process.exit(1);
});

user.resolver.ts

import { appDataSource } from '@server';
import { User } from '@entity/user.entity';

export class UserResolver {
    userRepo = appDataSource.getRepository(User);
}
