Class: APIError
Defined in: web/lib/errors.ts:93
API request error.
Remarks
Thrown when an API request fails. Used in frontend code when fetching data from backend endpoints. Captures HTTP status code and endpoint information for debugging.
Example
const response = await fetch('/api/preprints');
if (!response.ok) {
throw new APIError(
`Failed to fetch preprints: ${response.statusText}`,
response.status,
'/api/preprints'
);
}
Extends
Constructors
new APIError()
new APIError(
message,statusCode?,endpoint?,cause?):APIError
Defined in: web/lib/errors.ts:114
Creates a new APIError.
Parameters
message
string
Description of the API failure
statusCode?
number
HTTP status code (e.g., 404, 500)
endpoint?
string
API endpoint that failed (e.g., '/api/preprints')
cause?
Error
Original error (if chained)
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:"API_ERROR"='API_ERROR'
Defined in: web/lib/errors.ts:94
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).
Overrides

readonlyoptionalendpoint:string
Defined in: web/lib/errors.ts:104

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();
