Class: NetworkError
Defined in: web/lib/errors.ts:330
Network error for connection failures.
Remarks
Thrown when the network request fails (e.g., no internet, DNS failure, connection timeout). Distinct from API errors which indicate the server responded with an error.
Example
try {
await fetch('/api/preprints');
} catch (err) {
if (err instanceof TypeError) {
throw new NetworkError('Network request failed', err);
}
throw err;
}

Constructors
new NetworkError()
new NetworkError(
message,cause?):NetworkError
Defined in: web/lib/errors.ts:339
Creates a new NetworkError.
Parameters
message
string
Description of the network failure
cause?
Error
Original fetch error
Returns
Overrides
Properties
cause?
readonlyoptionalcause:Error
Defined in: web/lib/errors.ts:57
Original error that caused this error (if any).
Remarks
Error chaining allows tracking the full error context through multiple layers of the application. Useful for debugging complex error scenarios.

readonlycode:"NETWORK_ERROR"='NETWORK_ERROR'
Defined in: web/lib/errors.ts:331
Machine-readable error code.
Remarks
Error codes are unique identifiers for error types, enabling programmatic error handling (switch statements, error maps), error tracking in monitoring systems, and client-side error translation (i18n).

stackTraceLimit
staticstackTraceLimit:number
Defined in: node_modules/.pnpm/@types+node@22.19.1/node_modules/@types/node/globals.d.ts:68
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.

Methods
captureStackTrace()
staticcaptureStackTrace(targetObject,constructorOpt?):void
Defined in: node_modules/.pnpm/@types+node@22.19.1/node_modules/@types/node/globals.d.ts:52
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();
