Missing Transaction For Multi Write (ARCH3065)

Key typescript.orm.missing-transaction-for-multi-write · Severity warning · Category orm

When two or more dependent persistence operations in the same method are not wrapped in an explicit transaction/atomic block, a partial commit can occur. Wrap dependent writes.

Incorrect

await accountRepo.save(debit);   // succeeds
await accountRepo.save(credit);  // if this fails, debit is left committed

Correct

await dataSource.transaction(async (tx) => {
  await tx.save(debit);
  await tx.save(credit);
});

Fix

Group dependent write operations inside a single transaction/atomic block.
