Class: PluginError

Defined in: src/core/errors/plugin-error.ts:68

Error subclass for plugin lifecycle failures.

Example

const error = new PluginError({
message: 'Plugin failed to load',
attempted: 'Load plugin',
pluginName: 'my-plugin',
});

Failure Mode

Load failed — plugin module could not be imported

Failure Mode

Init failed — plugin setup() threw an error

Failure Mode

Incompatible version — plugin requires a different Praman version

Constructors

Constructor

new PluginError(options): PluginError

Defined in: src/core/errors/plugin-error.ts:91

Creates a new PluginError instance.

Parameters

options

PluginErrorOptions

Plugin error construction options including the required plugin name and optional version for diagnostic context.

Returns

PluginError

Example

import { PluginError } from '#core/errors/plugin-error.js';

const error = new PluginError({
message: 'Plugin incompatible with Praman v1.0',
attempted: 'Load plugin my-custom-auth',
pluginName: 'my-custom-auth',
pluginVersion: '0.5.0',
code: 'ERR_PLUGIN_INCOMPATIBLE',

stackTraceLimit

static stackTraceLimit: number

Defined in: node_modules/@types/node/globals.d.ts:67

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.

PramanError.stackTraceLimit

Methods

toAIContext()

toAIContext(): AIErrorContext & object

Defined in: src/core/errors/plugin-error.ts:141

Returns AI-agent-friendly context with plugin-specific diagnostic fields.

Returns

AIErrorContext & object

Base AI context extended with plugin name and version details.

Example

const ctx = error.toAIContext();
// LLM can use ctx.pluginName to locate the plugin package
// and ctx.pluginVersion to check compatibility requirements

Overrides

PramanError.toAIContext


toJSON()

toJSON(): SerializedPramanError & object

Defined in: src/core/errors/plugin-error.ts:118

Serializes this error to a JSON-safe object with plugin-specific fields.

Returns

SerializedPramanError & object

Base serialization extended with pluginName and pluginVersion.

Example

const json = error.toJSON();
console.log(json.pluginName); // 'my-custom-auth'
console.log(json.pluginVersion); // '0.5.0'

Overrides

PramanError.toJSON


toUserMessage()

toUserMessage(): string

Defined in: src/core/errors/base.ts:180

Formats the error for human-readable console output.

Returns

string

Multi-line formatted string with all diagnostic sections.

Example

console.error(error.toUserMessage());

Inherited from

PramanError.toUserMessage


captureStackTrace()

static captureStackTrace(targetObject, constructorOpt?): void

Defined in: node_modules/@types/node/globals.d.ts:51

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
