### stackTraceLimit

> `static` **stackTraceLimit**: `number`

Defined in: node\_modules/.pnpm/@types+node@26.2.0/node\_modules/@types/node/globals.d.ts:67

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.

#### Inherited from

`Error.stackTraceLimit`

## Methods

### captureStackTrace()

> `static` **captureStackTrace**(`targetObject`, `constructorOpt?`): `void`

Defined in: node\_modules/.pnpm/@types+node@26.2.0/node\_modules/@types/node/globals.d.ts:51

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();
```

#### Parameters

| Parameter | Type |
| ------ | ------ |
| `targetObject` | `object` |
| `constructorOpt?` | [`Function`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Function) |

#### Returns

`void`

#### Inherited from

`Error.captureStackTrace`

### isError()

> `static` **isError**(`error`): `error is Error`

Defined in: node\_modules/.pnpm/typescript@6.0.3/node\_modules/typescript/lib/lib.esnext.error.d.ts:21

Indicates whether the argument provided is a built-in Error instance or not.

#### Parameters

| Parameter | Type |
| ------ | ------ |
| `error` | `unknown` |

#### Returns

`error is Error`

#### Inherited from

`Error.isError`

***

### prepareStackTrace()

> `static` **prepareStackTrace**(`err`, `stackTraces`): `any`

Defined in: node\_modules/.pnpm/@types+node@26.2.0/node\_modules/@types/node/globals.d.ts:55

#### Parameters

| Parameter | Type |
| ------ | ------ |
| `err` | [`Error`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Error) |
| `stackTraces` | `CallSite`[] |

#### Returns
