Class: ThrownActionError ​

Defined in: packages/action/src/error.ts:29

Error class for wrapping exceptions thrown during action execution.

Preserves the original exception and provides a consistent error type for action-related failures. It extends the native Error class and includes the original exception for debugging purposes.

Example ​

typescript
const action = createAction()
  .with(async () => {
    const session = await getSession();
    if (!session) throw new Error('No session');
    return next({ session });
  })
  .do(async ({ ctx }) => {
    return await getUser(ctx.session.userId);
  });

try {
  const user = await action();
} catch (ex) {
  if (ex instanceof ThrownActionError) {
    console.error(ex.cause); // Original Error object
  }
}

type ​

readonly type: "ThrownActionError" = 'ThrownActionError'

Defined in: packages/action/src/error.ts:33

Used to distinguish this error from others with the same shape.

stackTraceLimit ​

static stackTraceLimit: number

Defined in: node_modules/.pnpm/@[email protected]/node_modules/@types/node/globals.d.ts:162

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

Methods ​

captureStackTrace() ​

static captureStackTrace(targetObject, constructorOpt?): void

Defined in: node_modules/.pnpm/@[email protected]/node_modules/@types/node/globals.d.ts:146

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

js
const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

js
function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}

a();
