🚀 Quick Start

Basic Server

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

const server = new TypedServer({
  serveDir: './public',
  cors: true,
  watch: true,           // Enable file watching
  injectReload: true,    // Inject live reload script
});

await server.start();
console.log('Server running on port 3000!');

Full Configuration

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

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

  // Development
  watch: true,
  injectReload: true,

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

  // SEO
  sitemap: true,

  // PWA
  appVersion: 'v1.0.0',
  manifest: {
    name: 'My App',
    short_name: 'myapp',
    start_url: '/',
    display: 'standalone',
    background_color: '#ffffff',
    theme_color: '#000000',
  },
});

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 = ctx.body;
    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 (request) => {
  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 (request) => {
  const itemId = (request as any).params.id;
  return new Response(JSON.stringify({ id: itemId }), {
    headers: { 'Content-Type': 'application/json' },
  });
});

// Wildcard routes
server.addRoute('/files/*path', 'GET', async (request) => {
  const filePath = (request as any).params.path;
  // Handle file serving logic
  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: 'john@example.com' };
  })
);

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

🛡️ 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();
