@codesoul-co/hypha-core / errors

Using this module

Use the Errors module for normalizing, classifying, or exposing error contracts. It exports 1 class, 1 function, 1 interface.

Import from the package entrypoint

ts
import {
  FrameworkError,
  isFrameworkError,
} from '@codesoul-co/hypha-core';

import type {
  FrameworkErrorInit,
} from '@codesoul-co/hypha-core';

Usage patterns

  • Use the 1 type/interface export as static contracts in application code, adapters, or tests. Import them with import type; they do not exist at runtime.
  • The module exposes 1 class as constructable runtime implementations. Each symbol entry lists its constructor and public methods.
  • The module exposes 1 function as direct operation entrypoints. Every overload, required/optional parameter, and return type is documented below.

FrameworkError

Framework Error class with 10 public constructor or member entries; its exact declarations are listed below.

  • Kind: class
  • Import: import { FrameworkError } from '@codesoul-co/hypha-core';
  • Source module: errors

Declaration

text
export declare class FrameworkError extends Error {
    readonly code: string;
    readonly context?: Record<string, unknown>;
    readonly cause?: unknown;
    constructor(init: FrameworkErrorInit);
}

Public members

MemberKindSignatureDescription
causepropertyreadonly cause?: unknownPublic property; its type, readonly modifier and optionality are shown in the signature.
codepropertyreadonly code: stringPublic property; its type, readonly modifier and optionality are shown in the signature.
constructorconstructor(init: FrameworkErrorInit): FrameworkErrorCreates an instance of this class.
contextpropertyreadonly context?: Record<string, unknown>Public property; its type, readonly modifier and optionality are shown in the signature.
messagepropertymessage: stringPublic property; its type, readonly modifier and optionality are shown in the signature.
namepropertyname: stringPublic property; its type, readonly modifier and optionality are shown in the signature.
stackpropertystack?: stringPublic property; its type, readonly modifier and optionality are shown in the signature.
static captureStackTracemethodstatic captureStackTrace(targetObject: object, constructorOpt?: Function): voidCreates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called. js 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: js 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();
static prepareStackTracemethodstatic prepareStackTrace(err: Error, stackTraces: NodeJS.CallSite[]): anyPublic method; parameters and return type are shown in the signature.
static stackTraceLimitpropertystatic stackTraceLimit: numberThe 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.
