runAll ​

Problem ​

You have a list of cleanup or teardown functions and need to run all of them even if some throw — collecting errors rather than stopping at the first failure.

Solution ​

Use runAll(fns, options?) to execute all functions and throw an AggregateError at the end if any failed.

ts
import { runAll } from '@vielzeug/arsenal';

const cleanups = [() => closeDatabase(), () => clearCache(), () => flushLogs()];

runAll(cleanups); // all three run; throws AggregateError if any fail

Reverse order (LIFO teardown) ​

ts
import { runAll } from '@vielzeug/arsenal';

runAll(cleanups, { reverse: true }); // runs last → first

Pitfalls ​

  • All functions run regardless of failures. The thrown AggregateError.errors array contains each individual error.
