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

APIError

Overrides

ChiveError.constructor

Properties

cause?

readonly optional cause: 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.

ChiveError.cause


code

readonly code: "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

ChiveError.code


endpoint?

readonly optional endpoint: string

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

API endpoint that was called.


message

message: string

name

name: string

Defined in: node_modules/.pnpm/typescript@5.5.4/node_modules/typescript/lib/lib.es5.d.ts:1076

stack?

optional stack: string

Defined in: node_modules/.pnpm/typescript@5.5.4/node_modules/typescript/lib/lib.es5.d.ts:1078

Inherited from

ChiveError.stack


statusCode?

readonly optional statusCode: number

Defined in: web/lib/errors.ts:99

HTTP status code from the failed request (if available).


stackTraceLimit

static stackTraceLimit: 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()

static captureStackTrace(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();

Parameters

targetObject

object

constructorOpt?

Function

Returns

void
