`Usage
This was built because we constantly wanted hooks and events extended on libraires we are building such as Keyv and Cacheable. This is a simple way to add hooks and events to your classes.javascript
import { Hookified } from 'hookified';class MyClass extends Hookified {
constructor() {
super();
}
async myMethodEmittingEvent() {
this.emit('message', 'Hello World'); //using Emittery
}
//with hooks you can pass data in and if they are subscribed via onHook they can modify the data
async myMethodWithHooks() Promise {
let data = { some: 'data' };
// do something
await this.hook('before:myMethod2', data);
return data;
}
}
`You can even pass in multiple arguments to the hooks:
javascript
import { Hookified } from 'hookified';class MyClass extends Hookified {
constructor() {
super();
}
async myMethodWithHooks() Promise {
let data = { some: 'data' };
let data2 = { some: 'data2' };
// do something
await this.hook('before:myMethod2', data, data2);
return data;
}
}

`API - Hooks
.throwOnHookError
If set to true, errors thrown in hooks will be thrown. If set to false, errors will be only emitted.
javascript
import { Hookified } from 'hookified';class MyClass extends Hookified {
constructor() {
super({ throwOnHookError: true });
}
}
const myClass = new MyClass();
console.log(myClass.throwOnHookError); // true. because it is set in super
try {
myClass.onHook('error-event', async () => {
throw new Error('error');
});
await myClass.hook('error-event');
} catch (error) {
console.log(error.message); // error
}
myClass.throwOnHookError = false;
console.log(myClass.throwOnHookError); // false
`.logger
If set, errors thrown in hooks will be logged to the logger. If not set, errors will be only emitted.javascript
import { Hookified } from 'hookified';
import pino from 'pino';const logger = pino(); // create a logger instance that is compatible with Logger type
class MyClass extends Hookified {
constructor() {
super({ logger });
}
async myMethodWithHooks() Promise {
let data = { some: 'data' };
// do something
await this.hook('before:myMethod2', data);
return data;
}
}
const myClass = new MyClass();
myClass.onHook('before:myMethod2', async () => {
throw new Error('error');
});
// when you call before:myMethod2 it will log the error to the logger
await myClass.hook('before:myMethod2');
`.enforceBeforeAfter
If set to true, enforces that all hook names must start with 'before' or 'after'. This is useful for maintaining consistent hook naming conventions in your application. Default is false.
javascript
import { Hookified } from 'hookified';class MyClass extends Hookified {
constructor() {
super({ enforceBeforeAfter: true });
}
}
const myClass = new MyClass();
console.log(myClass.enforceBeforeAfter); // true
// These will work fine
myClass.onHook('beforeSave', async () => {
console.log('Before save hook');
});
myClass.onHook('afterSave', async () => {
console.log('After save hook');
});
myClass.onHook('before:validation', async () => {
console.log('Before validation hook');
});
// This will throw an error
try {
myClass.onHook('customEvent', async () => {
console.log('This will not work');
});
} catch (error) {
console.log(error.message); // Hook event "customEvent" must start with "before" or "after" when enforceBeforeAfter is enabled
}
// You can also change it dynamically
myClass.enforceBeforeAfter = false;
myClass.onHook('customEvent', async () => {
console.log('This will work now');
});
`The validation applies to all hook-related methods:
-
, addHook(), onHookEntry(), onHooks()
- , onceHook(), prependOnceHook()
- , callHook()
- , removeHook(), removeHooks()Note: The
and afterHook() helper methods automatically generate proper hook names and work regardless of the enforceBeforeAfter setting..deprecatedHooks
A Map of deprecated hook names to deprecation messages. When a deprecated hook is used, a warning will be emitted via the 'warn' event and logged to the logger (if available). Default is an empty Map.
`javascript
import { Hookified } from 'hookified';// Define deprecated hooks with custom messages
const deprecatedHooks = new Map([
['oldHook', 'Use newHook instead'],
['legacyMethod', 'This hook will be removed in v2.0'],
['deprecatedFeature', ''] // Empty message - will just say "deprecated"
]);
class MyClass extends Hookified {
constructor() {
super({ deprecatedHooks });
}
}
const myClass = new MyClass();
console.log(myClass.deprecatedHooks); // Map with deprecated hooks
// Listen for deprecation warnings
myClass.on('warn', (event) => {
console.log(
Deprecation warning: ${event.message});
// event.hook contains the hook name
// event.message contains the full warning message
});// Using a deprecated hook will emit warnings
myClass.onHook('oldHook', () => {
console.log('This hook is deprecated');
});
// Output: Hook "oldHook" is deprecated: Use newHook instead
// Using a deprecated hook with empty message
myClass.onHook('deprecatedFeature', () => {
console.log('This hook is deprecated');
});
// Output: Hook "deprecatedFeature" is deprecated
// You can also set deprecated hooks dynamically
myClass.deprecatedHooks.set('anotherOldHook', 'Please migrate to the new API');
// Works with logger if provided
import pino from 'pino';
const logger = pino();
const myClassWithLogger = new Hookified({
deprecatedHooks,
logger
});
// Deprecation warnings will be logged to logger.warn
`The deprecation warning system applies to all hook-related methods:
- Registration:
, addHook(), onHookEntry(), onHooks(), prependHook(), onceHook(), prependOnceHook()
- Execution: , callHook()
- Management: , removeHook(), removeHooks()Deprecation warnings are emitted in two ways:
1. Event: A 'warn' event is emitted with
2. Logger: Logged to if a logger is configured and has a warn method.allowDeprecated
Controls whether deprecated hooks are allowed to be registered and executed. Default is true. When set to false, deprecated hooks will still emit warnings but will be prevented from registration and execution.
`javascript
import { Hookified } from 'hookified';const deprecatedHooks = new Map([
['oldHook', 'Use newHook instead']
]);
class MyClass extends Hookified {
constructor() {
super({ deprecatedHooks, allowDeprecated: false });
}
}
const myClass = new MyClass();
console.log(myClass.allowDeprecated); // false
// Listen for deprecation warnings (still emitted even when blocked)
myClass.on('warn', (event) => {
console.log(
Warning: ${event.message});
});// Try to register a deprecated hook - will emit warning but not register
myClass.onHook('oldHook', () => {
console.log('This will never execute');
});
// Output: Warning: Hook "oldHook" is deprecated: Use newHook instead
// Verify hook was not registered
console.log(myClass.getHooks('oldHook')); // undefined
// Try to execute a deprecated hook - will emit warning but not execute
await myClass.hook('oldHook');
// Output: Warning: Hook "oldHook" is deprecated: Use newHook instead
// (but no handlers execute)
// Non-deprecated hooks work normally
myClass.onHook('validHook', () => {
console.log('This works fine');
});
console.log(myClass.getHooks('validHook')); // [handler function]
// You can dynamically change the setting
myClass.allowDeprecated = true;
// Now deprecated hooks can be registered and executed
myClass.onHook('oldHook', () => {
console.log('Now this works');
});
console.log(myClass.getHooks('oldHook')); // [handler function]
`Behavior when
is false:
- Registration: All hook registration methods (onHook, addHook, prependHook, etc.) will emit warnings but skip registration
- Execution: Hook execution methods (hook, callHook) will emit warnings but skip execution
- Management: Hook management methods (getHooks, removeHook) will emit warnings and return undefined/skip operations
- Warnings: Deprecation warnings are always emitted regardless of allowDeprecated settingUse cases:
- Development: Keep
allowDeprecated: true to maintain functionality while seeing warnings
- Testing: Set allowDeprecated: false to ensure no deprecated hooks are accidentally used
- Migration: Gradually disable deprecated hooks during API transitions
- Production: Disable deprecated hooks to prevent legacy code execution.onHook(eventName, handler)

`.hook(eventName, ...args)
Run a hook event.
javascript

constructor() {
super();
}
async myMethodWithHooks() Promise {
let data = { some: 'data' };
// do something

This is a helper function that will prepend a hook name with
before:.`javascript

constructor() {
super();
}
async myMethodWithHooks() Promise {
let data = { some: 'data' };

after:myMethod2
await this.afterHook('myMethod2', data); return data;
}
}
.hookSync(eventName, ...args)
Run a hook event synchronously. Async handlers (functions declared with
keyword) are silently skipped and only synchronous handlers are executed.> Note: The
.hook() method is preferred as it executes both sync and async functions. Use .hookSync() only when you specifically need synchronous execution.`javascript
import { Hookified } from 'hookified';class MyClass extends Hookified {
constructor() {
super();
}
myMethodWithSyncHooks() {
let data = { some: 'data' };
// Only synchronous handlers will execute
this.hookSync('before:myMethod', data);
return data;
}
}
const myClass = new MyClass();
// This sync handler will execute
myClass.onHook('before:myMethod', (data) => {
data.some = 'modified';
});
// This async handler will be silently skipped
myClass.onHook('before:myMethod', async (data) => {

`API - Events
.throwOnEmitError
If set to true, errors emitted as
will be thrown if there are no listeners. If set to false, errors will be only emitted.`javascript

constructor() {
super();
}
async myMethodWithHooks() Promise {
let data = { some: 'data' };
// do something
await this.hook('before:myMethod2', data);

}
}
`.throwOnEmptyListeners
If set to true, errors will be thrown when emitting an
event with no listeners. This follows the standard Node.js EventEmitter behavior. Default is false. In version 2, this will be set to true by default.`javascript
import { Hookified } from 'hookified';class MyClass extends Hookified {
constructor() {
super({ throwOnEmptyListeners: true });
}
}
const myClass = new MyClass();
console.log(myClass.throwOnEmptyListeners); // true
// This will throw because there are no error listeners
try {
myClass.emit('error', new Error('Something went wrong'));
} catch (error) {
console.log(error.message); // Something went wrong
}
// Add an error listener - now it won't throw
myClass.on('error', (error) => {
console.log('Error caught:', error.message);
});
myClass.emit('error', new Error('This will be caught')); // No throw, listener handles it
// You can also change it dynamically
myClass.throwOnEmptyListeners = false;
console.log(myClass.throwOnEmptyListeners); // false
`Difference between
and throwOnEmptyListeners:
- throwOnEmitError: Throws when emitting 'error' event every time.
- throwOnEmptyListeners: Throws only when there are NO error listeners registeredWhen both are set to
true, throwOnEmitError takes precedence..on(eventName, handler)

`Logging
Hookified integrates logging directly into the event system. When a logger is configured, all emitted events are automatically logged to the appropriate log level based on the event name.
How It Works
When you emit an event, Hookified automatically sends the event data to the configured logger using the appropriate log method:
| Event Name | Logger Method |
|------------|---------------|
|
| logger.error() |
| warn | logger.warn() |
| debug | logger.debug() |
| trace | logger.trace() |
| fatal | logger.fatal() |
| Any other | logger.info() |The logger receives two arguments:
1. message: A string extracted from the event data (error messages, object messages, or JSON stringified data)
2. context: An object containing
{ event: eventName, data: originalData }Setting Up a Logger
Any logger that implements the
interface is compatible. This includes popular loggers like Pino, Winston, Bunyan, and others.`typescript
type Logger = {
trace: (message: string, ...args: unknown[]) => void;
debug: (message: string, ...args: unknown[]) => void;
info: (message: string, ...args: unknown[]) => void;
warn: (message: string, ...args: unknown[]) => void;
error: (message: string, ...args: unknown[]) => void;
fatal: (message: string, ...args: unknown[]) => void;
};
`Usage Example with Pino
javascript
import { Hookified } from 'hookified';
import pino from 'pino';const logger = pino();
class MyService extends Hookified {
constructor() {
super({ logger });
}
async processData(data) {
// This will log to logger.info with the data
this.emit('info', { action: 'processing', data });
try {
// ... process data
this.emit('debug', { action: 'completed', result: 'success' });
} catch (err) {
// This will log to logger.error with the error message
this.emit('error', err);
}
}
}
const service = new MyService();
// All events are automatically logged
service.emit('info', 'Service started'); // -> logger.info()
service.emit('warn', { message: 'Low memory' }); // -> logger.warn()
service.emit('error', new Error('Failed')); // -> logger.error()
service.emit('custom-event', { foo: 'bar' }); // -> logger.info() (default)
`You can also set or change the logger after instantiation:
javascript
const service = new MyService();
service.logger = pino({ level: 'debug' });// Or remove the logger
service.logger = undefined;
`Benchmarks
We are doing very simple benchmarking to see how this compares to other libraries using
. This is not a full benchmark but just a simple way to see how it performs. Our goal is to be as close or better than the other libraries including native (EventEmitter).Hooks
