OptionalcauseReadonlynameDiscriminating name for instanceof-free checks.
OptionalstackStaticstackThe 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.
StaticcaptureCreates 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();

The Cloudflare counterpart of
messaging-plugin'sRequestTimeoutError. They are deliberately distinct classes rather than one shared identity: AI_GUIDELINES §2.2 forbids a plugin importing another plugin, andcommoncarries no error class to promote one into (§2.1 limits it to types, interfaces, constants and pure utilities). Which class an application catches is never ambiguous —MessagingPluginand this package'smessagingarm both provideCAPABILITIES.MESSAGING, so the kernel's duplicate-provider check guarantees exactly one of them is registered.Since
