question: getting error "Cannot get connection "default" from connection manager."

[bidipeppercrap]

TypeORM version: 0.2.18
Extension version: 0.2.3

await createConnection();

I'm using the default .env connection config.

Same Issue, the following message appears:

Error: Cannot get connection "default" from the connection manager. Make sure you have created such conn
ection. Also make sure you have called useContainer(Container) in your application before you establishe
d a connection and importing any entity.

even when the code goes as follows:

    const loadedConnectionOptions = await getConnectionOptions();

    const connectionOptions = Object.assign(loadedConnectionOptions, {
        type: env.db.type as any, // See createConnection options for valid types
        host: env.db.host,
        port: env.db.port,
        username: env.db.username,
        password: env.db.password,
        database: env.db.database,
        synchronize: env.db.synchronize,
        logging: env.db.logging,
        entities: env.app.dirs.entities,
        migrations: env.app.dirs.migrations,
    });

    const connection = await createConnection(connectionOptions);

    if (settings) {
        settings.setData('connection', connection);
        settings.onShutdown(() => connection.close());
    }

I assume you figured it out but for others coming here:

Check this issue #487 (typeorm/typeorm#487) in index.ts add

typeorm.useContainer(typedi.Container);

I had the same error and it solved the problem.

Cannot reproduce. As the docs and @ethernal says: you need to configure TypeORM to use the TypeDI container before you can use the decorators.

import { createConnection, useContainer } from 'typeorm';
import { Container } from 'typedi';

/** Tell TypeORM to use the TypeDI container to resolve it's dependencies. */
useContainer(Container);

/** Create a connection and start using TypeORM. */
createConnection({
  /* <connection options> */
}).catch(error => {
  console.error(`Couldn't connect to the database!`);
  console.error(error);
});
