Class: InvalidRouteHandlerError

API / @xmachines/play-xstate / errors / InvalidRouteHandlerError

Defined in: packages/play-xstate/src/errors.ts:206

formatPlayRouteTransitions() throws this error for a meta.route object whose handler field holds a value that the routing layer does not know.

The field decides WHERE the generated play.route transition sits, and each value produces a different reachability. "local" in particular makes a state reachable only while its parent is active. A typo such as "locale" would therefore fall back to a placement that the author did not ask for, and the route would behave correctly in the test that the author wrote and wrongly everywhere else. The error refuses the value instead.

Error code: PLAY_XSTATE_INVALID_ROUTE_HANDLER

Example

import { InvalidRouteHandlerError } from "@xmachines/play-xstate/errors";

try {
  formatPlayRouteTransitions(config);
} catch (error) {
  if (error instanceof InvalidRouteHandlerError) {
    console.error(error.handler); // the value that the config declared
  }
}

Properties

Property	Modifier	Type	Description	Inherited from	Defined in
`cause?`	`public`	`unknown`	-	`PlayError`.`cause`	-
`code`	`readonly`	`string`	A stable, machine-readable identifier of the error. An error code follows the naming convention `PLAY_<PACKAGE>_<DESCRIPTION>`. It stays the same across each patch release and each minor release of one major version. Never match on `.message`. Always match on `.code`, or on the subclass.	`PlayError`.`code`	packages/play/src/errors.ts:76
`handler`	`readonly`	`string`	The value that the config declared, as a string, for the debug work.	-	packages/play-xstate/src/errors.ts:208
`message`	`public`	`string`	-	`PlayError`.`message`	-
`name`	`public`	`string`	-	`PlayError`.`name`	-
`scope`	`readonly`	`string`	The class or the module that threw this error, for example `"RouterBridgeBase"`.	`PlayError`.`scope`	packages/play/src/errors.ts:66
`stack?`	`public`	`string`	-	`PlayError`.`stack`	-
`stackTraceLimit`	`static`	`number`	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.	`PlayError`.`stackTraceLimit`	-

Methods

captureStackTrace()

static captureStackTrace(targetObject, constructorOpt?): void;

Defined in: @types/node

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

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:

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();
