Plugin Development Toolkit

Overview

Complete development environment for creating plugins across different platforms including OpenCode, VS Code, Chrome, WordPress, and more. Provides scaffolding, testing, validation, and deployment utilities.

Quick Start

Installation

npm install -g @plugin-dev/cli
# or
npx @plugin-dev/cli create my-plugin

Create New Plugin

# Interactive plugin creation
plugin-dev create

# Create specific type
plugin-dev create --type=opencode --name=my-awesome-plugin
plugin-dev create --type=vscode --name=my-extension
plugin-dev create --type=chrome --name=my-browser-extension

Plugin Types

OpenCode Plugins

# Create OpenCode plugin
plugin-dev create opencode my-plugin --template=skill

# Generated structure
my-plugin/
├── package.json
├── README.md
├── index.js
├── tests/
│   └── plugin.test.js
└── docs/
    └── api.md

OpenCode Plugin Template

// index.js
module.exports = {
  name: 'my-plugin',
  version: '1.0.0',
  description: 'My awesome OpenCode plugin',
  type: 'skill',
  
  async initialize() {
    console.log('Plugin initialized');
  },
  
  async execute(input) {
    // Plugin logic here
    return {
      success: true,
      result: 'Plugin executed successfully'
    };
  }
};

Advanced Features

Plugin Hooks

// index.js
module.exports = {
  name: 'my-plugin',
  
  // Lifecycle hooks
  async beforeInitialize() {
    console.log('About to initialize...');
  },
  
  async initialize() {
    // Initialization logic
  },
  
  async beforeExecute(input) {
    console.log('About to execute with:', input);
    return input; // Can modify input
  },
  
  async execute(input) {
    // Main plugin logic
    return { success: true, result: 'done' };
  },
  
  async afterExecute(result) {
    console.log('Execution result:', result);
    return result; // Can modify result
  },
  
  async beforeDestroy() {
    console.log('About to destroy plugin...');
  },
  
  async destroy() {
    // Cleanup logic
  }
};

Plugin Communication

// Inter-plugin communication
const { PluginBus } = require('@plugin-dev/communication');

// Subscribe to events
PluginBus.on('user:login', (user) => {
  console.log('User logged in:', user.id);
});

// Emit events
PluginBus.emit('plugin:ready', {
  plugin: 'my-plugin',
  version: '1.0.0'
});

// Direct plugin messaging
const otherPlugin = PluginBus.getPlugin('other-plugin');
const response = await otherPlugin.sendMessage('process', { data: 'test' });

Plugin Storage

// Persistent storage
const { PluginStorage } = require('@plugin-dev/storage');

// Local storage
const localStore = new PluginStorage('local');
await localStore.set('config', { theme: 'dark' });
const config = await localStore.get('config');

// Cloud storage
const cloudStore = new PluginStorage('cloud', {
  provider: 'aws',
  bucket: 'my-plugin-storage'
});
await cloudStore.set('user-data', userData);

Platform Integration

OpenCode Integration

// OpenCode-specific features
const { OpenCodeAPI } = require('@plugin-dev/platforms');

const opencode = new OpenCodeAPI();

// Register commands
opencode.registerCommand('my-plugin.action', () => {
  console.log('Action executed');
});

// Access OpenCode services
const fileSystem = opencode.getService('filesystem');
const editor = opencode.getService('editor');
const terminal = opencode.getService('terminal');

VS Code Integration

// VS Code API access
const vscode = require('vscode');

// Register commands
vscode.commands.registerCommand('my-plugin.hello', () => {
  vscode.window.showInformationMessage('Hello from my plugin!');
});

// Register language features
const provider = vscode.languages.registerCompletionItemProvider(
  'javascript',
  {
    provideCompletionItems(document, position) {
      // Return completion items
    }
  }
);

Chrome Integration

// Chrome API access
chrome.runtime.onMessage.addListener((request, sender, sendResponse) => {
  if (request.action === 'getData') {
    // Handle request
    sendResponse({ data: 'result' });
  }
});

// Storage API
chrome.storage.local.set({ key: 'value' });
chrome.storage.local.get(['key'], (result) => {
  console.log(result.key);
});
