Transaction Manager

The ITransactionManager port provides a way to coordinate persistence operations across multiple repositories in a transactional context. This ensures that domain events, snapshots, and metadata changes are committed atomically.

ITransactionManager

The responsibility of the ITransactionManager is to set up a transactional context for persistence. It must provide a transaction method that ensures transactionality of all repository operations performed within it. If an unhandled error is thrown within the transaction method, the transaction must be rolled back. If the transaction method returns without throwing, the transaction must be committed.

It should be implemented like so:

import type { ITransactionManager, RunInTransaction } from "@dugongjs/core";

export class TransactionManager implements ITransactionManager {
    public async transaction<TResult = unknown>(runInTransaction: RunInTransaction<TResult>): Promise<TResult> {
        // Implementation here...
    }
}
