# Build APIs That Can Be Extended Like Never Before

🪝 Hooked API

The extensible API framework for Node.js

--- ## Why Hooked API? Building APIs is easy. Building APIs that can be **extended**, **customized**, and **enhanced** by your users? That's hard. Until now. Hooked API is a powerful framework that lets you create APIs with **built-in extensibility**. Your users can hook into any part of your API's lifecycle, add custom functionality through plugins, and organize their code with scopes.

🚀 Key Features

🪝 Powerful Hook System

Let users intercept and modify behavior at any point in your API's execution

🔌 Plugin Architecture

Bundle functionality into reusable plugins with dependencies and lifecycle management

📦 Scoped Methods

Organize API methods into logical scopes (like database tables or resource types)

🛡️ Built-in Security

Prototype pollution protection, input validation, and frozen configurations

📊 Comprehensive Logging

Multi-level logging with custom loggers and performance tracking

🔄 Version Management

Built-in API registry with semver support for smooth migrations

## See It In Action Here's how simple it is to create an extensible database API: ```javascript import { Api } from 'hooked-api'; // Create your API const api = new Api({ name: 'my-db', version: '1.0.0' }); // Add methods that can be hooked api.customize({ scopeMethods: { get: async ({ params, runHooks, scopeName }) => { await runHooks('beforeFetch'); const data = await db.fetch(scopeName, params.id); await runHooks('afterFetch'); return data; } } }); // Users can extend with plugins await api.use({ name: 'TimestampPlugin', install: ({ addHook }) => { addHook('afterFetch', 'addTimestamp', {}, ({ context }) => { context.record.fetchedAt = new Date(); }); } }); // Create scopes for different resources api.addScope('users'); api.addScope('posts'); // Use it! const user = await api.scopes.users.get({ id: 123 }); // user now has fetchedAt timestamp added by the plugin! ``` ## Perfect For

🗄️ Database Abstractions
Let users customize queries, add computed fields, or implement caching

🌐 API Clients
Allow request/response transformation, retry logic, and custom authentication

🏗️ Framework Building
Create frameworks where every aspect can be customized by developers

🔧 Developer Tools
Build CLIs and tools that can be extended with community plugins

## What Developers Are Probably Thinking > "Finally, an API framework that doesn't fight me when I need to add custom behavior. The hook system is brilliant!" - *Senior Developer* > "We replaced our entire homegrown plugin system with Hooked API. It's more powerful and our code is cleaner." - *Tech Lead* > "The scope feature is perfect for our multi-tenant application. Each tenant gets their own customized API behavior." - *SaaS Founder* ## Ready to Get Started?
