import { TypedServer } from '@api.global/typedserver';

const server = new TypedServer({
  port: 8080,
  serveDir: './dist',
  cors: true,

  // Development
  watch: true,
  injectReload: true,
  noCache: true,            // Disable browser caching

  // Production
  forceSsl: true,
  spaFallback: true,        // Serve index.html for client-side routes

    display: 'standalone',
    background_color: '#ffffff',
    theme_color: '#000000',
  },

  // Compression
  compression: {
    enabled: true,
    algorithms: ['br', 'gzip'],
    threshold: 1024,
  },
});

await server.start();

🛣️ Routing

TypedServer uses a unified routing system powered by @push.rocks/smartserve. You can add routes using decorators or the programmatic API.

Decorator-Based Routing

Create clean, expressive controllers using decorators:

import * as smartserve from '@push.rocks/smartserve';

@smartserve.Route('/api/users')
class UserController {
  @smartserve.Get('/')
  async listUsers(ctx: smartserve.IRequestContext): Promise<Response> {
    const users = await getUsersFromDb();
    return new Response(JSON.stringify(users), {
      headers: { 'Content-Type': 'application/json' },
    });
  }

  @smartserve.Get('/:id')
  async getUser(ctx: smartserve.IRequestContext): Promise<Response> {
    const userId = ctx.params.id;
    const user = await getUserById(userId);
    return new Response(JSON.stringify(user), {
      headers: { 'Content-Type': 'application/json' },
    });
  }

  @smartserve.Post('/')
  async createUser(ctx: smartserve.IRequestContext): Promise<Response> {
    const userData = await ctx.json();
    const newUser = await createUserInDb(userData);
    return new Response(JSON.stringify(newUser), {
      status: 201,
      headers: { 'Content-Type': 'application/json' },
    });
  }
}

// Register the controller
smartserve.ControllerRegistry.registerInstance(new UserController());

Programmatic Routes with addRoute()

Add routes dynamically using the addRoute() API:

import { TypedServer } from '@api.global/typedserver';

const server = new TypedServer({ serveDir: './public', cors: true });

// Simple route
server.addRoute('/api/health', 'GET', async (ctx) => {
  return new Response(JSON.stringify({ status: 'ok' }), {
    headers: { 'Content-Type': 'application/json' },
  });
});

// Route with parameters (Express-style :param syntax)
server.addRoute('/api/items/:id', 'GET', async (ctx) => {
  const itemId = ctx.params.id;
  return new Response(JSON.stringify({ id: itemId }), {
    headers: { 'Content-Type': 'application/json' },
  });
});

// Wildcard routes
server.addRoute('/files/*path', 'GET', async (ctx) => {
  const filePath = ctx.params.path;
  return new Response(`Requested: ${filePath}`);
});

await server.start();

🔌 Type-Safe API Integration

Adding TypedRequest Handlers

import { TypedServer } from '@api.global/typedserver';
import * as typedrequest from '@api.global/typedrequest';

// Define your typed request interface
interface IGetUser extends typedrequest.implementsTR<IGetUser> {
  method: 'getUser';
  request: { userId: string };
  response: { name: string; email: string };
}

const server = new TypedServer({ serveDir: './public', cors: true });

// Add a typed handler directly to the server's router
server.typedrouter.addTypedHandler<IGetUser>(
  new typedrequest.TypedHandler('getUser', async (data) => {
    return { name: 'John Doe', email: '[email protected]' };
  })
);

await server.start();

Real-Time WebSocket Communication

TypedServer automatically sets up TypedSocket for real-time communication:

import { TypedServer } from '@api.global/typedserver';
import * as typedrequest from '@api.global/typedrequest';

interface IChatMessage extends typedrequest.implementsTR<IChatMessage> {
  method: 'sendMessage';
  request: { text: string; room: string };
  response: { messageId: string; timestamp: number };
}

const server = new TypedServer({ serveDir: './public', cors: true });

// Handle real-time messages
server.typedrouter.addTypedHandler<IChatMessage>(
  new typedrequest.TypedHandler('sendMessage', async (data) => {
    return { messageId: crypto.randomUUID(), timestamp: Date.now() };
  })
);

await server.start();

// Push messages to connected clients
const connections = await server.typedsocket.findAllTargetConnectionsByTag('allClients');
for (const conn of connections) {
  // Push to specific clients via TypedSocket
}

☁️ Edge Worker (Cloudflare Workers)

Deploy your application to the edge with Cloudflare Workers:

import { EdgeWorker, DomainRouter } from '@api.global/typedserver/edgeworker';

const worker = new EdgeWorker();

// Configure domain routing with caching
worker.domainRouter.addDomainInstruction({
  domainPattern: '*.example.com',
  originUrl: 'https://origin.example.com',
  type: 'cache',
  cacheConfig: { maxAge: 3600 },
});

// Pass-through to origin for API routes
worker.domainRouter.addDomainInstruction({
  domainPattern: 'api.example.com',
  originUrl: 'https://api-origin.example.com',
  type: 'origin',
});

// Cloudflare Worker entry point
export default {
  fetch: worker.fetchFunction.bind(worker),
};

🔧 Service Worker Client

Manage service workers in your frontend application:

import { getServiceworkerClient } from '@api.global/typedserver/web_serviceworker_client';

// Initialize and register service worker
const swClient = await getServiceworkerClient({
  pollInterval: 30000,  // Poll for updates every 30s
});

// The service worker handles:
// - Cache invalidation from server
// - Offline support
// - Background sync
// - Version updates

📦 Bundled Content

Serve pre-bundled content directly from memory — useful for single-binary deployments or embedding assets in server-side code:

import { TypedServer } from '@api.global/typedserver';

const server = new TypedServer({
  cors: true,
  bundledContent: [
    {
      path: '/index.html',
      contentBase64: Buffer.from('<html><body>Hello!</body></html>').toString('base64'),
    },
    {
      path: '/app.js',
      contentBase64: Buffer.from('console.log("loaded")').toString('base64'),
    },
  ],
  spaFallback: true,
});

await server.start();

Bundled content takes priority over filesystem serving and supports ETag-based conditional requests with immutable caching.

🛡️ Security Headers

Configure comprehensive security headers including CSP, HSTS, and more:

import { TypedServer } from '@api.global/typedserver';

const server = new TypedServer({
  serveDir: './dist',
  cors: true,

  securityHeaders: {
    // Content Security Policy
    csp: {
      defaultSrc: ["'self'"],
      scriptSrc: ["'self'", "'unsafe-inline'", 'https://cdn.example.com'],
      styleSrc: ["'self'", "'unsafe-inline'"],
      imgSrc: ["'self'", 'data:', 'https:'],
      connectSrc: ["'self'", 'wss:', 'https://api.example.com'],
      fontSrc: ["'self'", 'https://fonts.gstatic.com'],
      frameAncestors: ["'none'"],
      upgradeInsecureRequests: true,
    },

    // HSTS (HTTP Strict Transport Security)
    hstsMaxAge: 31536000,         // 1 year
    hstsIncludeSubDomains: true,
    hstsPreload: true,

    // Other security headers
    xFrameOptions: 'DENY',
    xContentTypeOptions: true,
    xXssProtection: true,
    referrerPolicy: 'strict-origin-when-cross-origin',

    // Cross-Origin policies
    crossOriginOpenerPolicy: 'same-origin',
    crossOriginEmbedderPolicy: 'require-corp',
    crossOriginResourcePolicy: 'same-origin',

    // Permissions Policy
    permissionsPolicy: {
      camera: [],
      microphone: [],
      geolocation: ['self'],
    },
  },
});

await server.start();

🗜️ Compression

TypedServer supports automatic response compression using Brotli and Gzip. Compression is powered by smartserve and enabled by default.

Configuration

import { TypedServer } from '@api.global/typedserver';

const server = new TypedServer({
  serveDir: './dist',
  cors: true,

  // Enable with defaults (brotli + gzip, threshold: 1024 bytes)
  compression: true,

  // Or disable completely
  // compression: false,

  // Or configure in detail
  // compression: {
  //   enabled: true,
  //   algorithms: ['br', 'gzip'],    // Preferred order
  //   threshold: 1024,               // Min size to compress (bytes)
  //   level: 4,                      // Compression level (1-11 for brotli, 1-9 for gzip)
  //   exclude: ['/api/stream/*'],    // Skip these paths
  // },
});

Request Admission

Admission callbacks let one server expose different surfaces by host, path, origin, or TypedRequest method:

const server = new TypedServer({
  requestAdmission: (context) => {
    const host = new URL(context.request.url).hostname;
    return host === 'api.example.com';
  },
  websocketAdmission: (context) => {
    return context.request.headers.get('origin') === 'https://app.example.com';
  },
  typedRequestAdmission: (request, context) => {
    const host = new URL(context.request.url).hostname;
    return host !== 'login.example.com' || request.method === 'login';
  },
});

Return false for a 403 rejection, a Response for a custom rejection, or true/void to continue. Rejected requests retain configured security headers without receiving CORS headers. HTTP TypedRequest handlers receive the server-owned request context as tools.localData.requestContext; caller localData cannot replace it.
