Advanced Features

This page introduces advanced features and usage of Gaia-X.

Plugin System

Gaia-X provides a powerful plugin system that allows you to extend and customize application functionality.

Creating Plugins

import { createPlugin } from 'gaia-x'

// Create a plugin
const myPlugin = createPlugin({
  name: 'my-plugin',
  // Plugin lifecycle hooks
  install(app, options) {
    // Executed when the plugin is installed
    app.provide('feature', () => {
      // Implement plugin functionality
    })
  },
  start() {
    // Executed when the application starts
  },
  stop() {
    // Executed when the application stops
  }
})

// Using the plugin
app.use(myPlugin, {
  // Plugin configuration options
})

Built-in Plugins

Gaia-X provides several built-in plugins that can be used out of the box:

Logger: Provides logging functionality
State: Provides state management functionality
Router: Provides routing management functionality

import { LoggerPlugin, StatePlugin, RouterPlugin } from 'gaia-x/plugins'

app.use(LoggerPlugin, {
  level: 'info'
})

app.use(StatePlugin)

app.use(RouterPlugin, {
  routes: [
    // Route configuration
  ]
})

Middleware

Middleware allows you to insert custom logic into the application processing pipeline.

Adding Middleware

app.use((context, next) => {
  // Pre-processing
  console.log('Before processing')
  
  // Call next middleware
  next()
  
  // Post-processing
  console.log('After processing')
})

Asynchronous Middleware

app.use(async (context, next) => {
  // Asynchronous pre-processing
  await someAsyncOperation()
  
  // Call next middleware
  await next()
  
  // Asynchronous post-processing
  await anotherAsyncOperation()
})

Advanced Configuration

Custom Loaders

import { createLoader } from 'gaia-x'

const customLoader = createLoader({
  // Loader configuration
  async load(resource) {
    // Implement resource loading logic
    return await fetchResource(resource)
  }
})

app.use(customLoader)

Performance Optimization

app.configure({
  performance: {
    // Enable performance tracking
    enableTracking: true,
    // Set performance budgets
    budget: {
      cpu: 100, // ms
      memory: 50 // MB
    }
  }
})
