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();
OptionalconstructorOpt: FunctionStaticprepare
Raised when a derived compute reads a dependency that was neither declared at registration nor resolvable as a live graph node — i.e. a dynamic read of a node that does not exist on the graph.
Remarks
SPEC §10.3 permits a compute to rewire its dependency set across recomputes (a conditional read
get => get(flag) ? get(a) : get(b)legitimately widens{flag,a}to{flag,b}). The engine honours that rewiring: a read outside the declared set is resolved and the widened edge set re-registered so subsequent commits fire correctly. This error is the residual guard for the ONE case that cannot be honoured — a read of aNodeIdthat was never registered on the graph at all. It replaces the rawErrorthe wasm path previously threw for any out-of-set read, so program validity is engine- independent: an unresolvable read is a typed CauslError on both the TS floor and the wasm engine.Param: derivedId
The derived node whose compute performed the read.
Param: depId
The unresolvable dependency id that was read.
