Class: DuplicateBridgeError

API / @xmachines/play-router / errors / DuplicateBridgeError

Defined in: packages/play-router/src/errors.ts:75

RouterBridgeBase.connect() throws this error when a second bridge connects to an actor with an active bridge connection.

One actor can hold one router bridge at a time. Two bridges of the same actor both receive and process every navigation event of the router. They therefore send two play.route events to the actor, and their lastSyncedPath values of the echo suppression contradict each other.

The remedy: call bridge.disconnect() on the first bridge before you connect the second one. You can also permit one active connectRouter() call for each actor at a time.

Error code: PLAY_ROUTER_DUPLICATE_BRIDGE

Example

import { DuplicateBridgeError } from "@xmachines/play-router/errors";

try {
  bridge.connect();
} catch (err) {
  if (err instanceof DuplicateBridgeError) {
    console.error("Actor already has an active router bridge — disconnect first.");
  }
}

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
`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();
