Page 5: Practical Applications

Welcome to the practical applications page of WebSim AI. Here you'll find useful functions that can be applied in real-world web development scenarios.

• websim.createProgressiveWebApp(pwaConfig)

  Sets up the necessary components to turn a website into a Progressive Web App (PWA), enhancing the user experience with offline capabilities and native-like features.

  const pwa = websim.createProgressiveWebApp({ name: 'My Awesome PWA', shortName: 'MyPWA', startUrl: '/', themeColor: '#4A90E2', backgroundColor: '#FFFFFF', icons: [ { src: '/icon-192x192.png', sizes: '192x192', type: 'image/png' }, { src: '/icon-512x512.png', sizes: '512x512', type: 'image/png' } ] }); pwa.register().then(() => { console.log('PWA registered successfully'); }); pwa.onUpdate(() => { console.log('New content is available; please refresh.'); }); pwa.onOffline(() => { console.log('App is running in offline mode'); });
• websim.implementWebPushNotifications(pushConfig)

  Implements Web Push Notifications, allowing your web application to send notifications to users even when the app is not actively running in the browser.

  const pushNotifications = websim.implementWebPushNotifications({ publicKey: 'BLc_vwF8CCjnqHSrKtVKyFNvOoE2U92HsXZ-EUgdQS-v7iiozxrn8_nnEcec8TOv_COV9UkEw5TiD_GkrkYGYdM', serviceWorkerPath: '/service-worker.js' }); pushNotifications.requestPermission().then((permission) => { if (permission === 'granted') { console.log('Notification permission granted'); return pushNotifications.subscribe(); } }).then((subscription) => { console.log('User is subscribed:', subscription); // Send subscription to your server }); pushNotifications.onNotificationClick((event) => { console.log('Notification clicked:', event.notification.title); });
• websim.createVirtualDOM(vdomConfig)

  Creates a lightweight Virtual DOM implementation for efficient DOM manipulation and rendering, similar to popular frameworks but customizable for your specific needs.

  const vdom = websim.createVirtualDOM({ rootElement: document.getElementById('app'), diffAlgorithm: 'efficient' }); function renderApp(state) { return vdom.h('div', { class: 'app' }, [ vdom.h('h1', null, state.title), vdom.h('p', null, state.content), vdom.h('button', { onClick: state.handleClick }, 'Click me') ]); } let appState = { title: 'Hello, Virtual DOM!', content: 'This is a simple example.', handleClick: () => { appState.content = 'The button was clicked!'; vdom.render(renderApp(appState)); } }; vdom.render(renderApp(appState));
• websim.implementWebGL(webglConfig)

  Implements WebGL for high-performance 2D and 3D graphics rendering in the browser, providing a simple API for complex visualizations.

  const gl = websim.implementWebGL({ canvas: document.getElementById('webgl-canvas'), antialias: true }); const scene = gl.createScene(); const camera = gl.createCamera({ fov: 45, aspect: 1, near: 0.1, far: 1000 }); const cube = gl.createCube({ size: 1, color: '#ff0000' }); scene.add(cube); camera.position.z = 5; gl.animate(() => { cube.rotation.x += 0.01; cube.rotation.y += 0.01; gl.render(scene, camera); }); gl.onResize(() => { camera.aspect = window.innerWidth / window.innerHeight; camera.updateProjectionMatrix(); gl.setSize(window.innerWidth, window.innerHeight); });
• websim.createStateManagement(stateConfig)

  Creates a centralized state management system for your application, similar to Redux but with a simpler API and built-in optimizations.

  const store = websim.createStateManagement({ initialState: { count: 0, todos: [] }, reducers: { INCREMENT: (state) => ({ ...state, count: state.count + 1 }), ADD_TODO: (state, action) => ({ ...state, todos: [...state.todos, action.payload] }) } }); store.subscribe((state) => { console.log('State updated:', state); renderApp(state); }); store.dispatch({ type: 'INCREMENT' }); store.dispatch({ type: 'ADD_TODO', payload: 'Learn WebSim AI' }); function renderApp(state) { document.getElementById('count').textContent = state.count; document.getElementById('todos').innerHTML = state.todos.map(todo => `
• ${todo}
`).join(''); }
• websim.implementWebAssembly(wasmConfig)

  Implements WebAssembly integration, allowing you to run high-performance code written in languages like C++ or Rust in the browser.

  const wasm = websim.implementWebAssembly({ wasmUrl: '/path/to/my_module.wasm', importObject: { env: { memory: new WebAssembly.Memory({ initial: 256, maximum: 512 }), log: (value) => console.log(value) } } }); wasm.instantiate().then((instance) => { const { exports } = instance; // Call a function defined in WebAssembly const result = exports.fibonacci(10); console.log('Fibonacci(10):', result); // Use a WebAssembly function in a performance-critical loop const arr = new Int32Array(exports.memory.buffer, 0, 1000); for (let i = 0; i < 1000; i++) { arr[i] = exports.complexCalculation(i); } });
• websim.createWebComponents(componentsConfig)

  Creates a system for defining and using Web Components, allowing you to create reusable, encapsulated HTML elements with their own styling and behavior.

  const { defineComponent, useState, useEffect } = websim.createWebComponents(); defineComponent('custom-counter', { template: ({ count, increment }) => `

  Count: ${count}

  Increment

  `, setup() { const [count, setCount] = useState(0); const increment = () => setCount(count + 1); useEffect(() => { console.log('Count changed:', count); }, [count]); return { count, increment }; } }); // Usage in HTML //
• websim.implementWebRTC(webrtcConfig)

  Implements WebRTC (Web Real-Time Communication) for peer-to-peer audio, video, and data communication directly between browsers without the need for plugins or native apps.

  const rtc = websim.implementWebRTC({ iceServers: [ { urls: 'stun:stun.l.google.com:19302' } ], mediaConstraints: { audio: true, video: { width: 1280, height: 720 } } }); rtc.createPeerConnection().then((pc) => { rtc.getUserMedia().then((stream) => { document.getElementById('localVideo').srcObject = stream; stream.getTracks().forEach(track => pc.addTrack(track, stream)); }); pc.ontrack = (event) => { document.getElementById('remoteVideo').srcObject = event.streams[0]; }; return rtc.createOffer(pc); }).then((offer) => { console.log('Offer created:', offer); // Send offer to remote peer using your signaling mechanism }); rtc.onDataChannel((channel) => { channel.onmessage = (event) => { console.log('Received message:', event.data); }; channel.send('Hello from WebRTC!'); });
• websim.createAccessibilityTester(a11yConfig)

  Creates an accessibility testing tool to check your web application for common accessibility issues and provide suggestions for improvements.

  const a11yTester = websim.createAccessibilityTester({ rules: ['wcag2a', 'wcag2aa'], ignore: ['region'] }); a11yTester.test(document).then((results) => { console.log('Accessibility test results:', results); results.violations.forEach((violation) => { console.log(`${violation.impact} impact issue:`, violation.help); console.log('Affected elements:', violation.nodes.map(node => node.target)); }); if (results.violations.length === 0) { console.log('No accessibility issues found!'); } }); a11yTester.onDOMChange(() => { console.log('DOM changed, re-running accessibility tests...'); a11yTester.test(document); });
• websim.implementGraphQL(graphqlConfig)

  Implements a GraphQL client for efficient data fetching and management in your web application, with built-in caching and real-time updates.

  const graphql = websim.implementGraphQL({ endpoint: 'https://api.example.com/graphql', headers: { 'Authorization': 'Bearer YOUR_TOKEN_HERE' } }); const GET_USER = ` query GetUser($id: ID!) { user(id: $id) { id name email posts { id title } } } `; graphql.query(GET_USER, { id: '123' }).then((result) => { console.log('User data:', result.data.user); }); const CREATE_POST = ` mutation CreatePost($input: CreatePostInput!) { createPost(input: $input) { id title content } } `; graphql.mutate(CREATE_POST, { input: { title: 'New Post', content: 'This is a new post.' } }).then((result) => { console.log('Created post:', result.data.createPost); }); graphql.subscribe('POSTS_SUBSCRIPTION', (data) => { console.log('Received real-time update:', data); });
