Quick Start
import { SmartServe, Route, Get, Post, type IRequestContext } from '@push.rocks/smartserve';
@Route('/api')
class UserController {
@Get('/hello')
hello() {
return { message: 'Hello World! 👋' };
}
@Get('/users/:id')
getUser(ctx: IRequestContext) {
return { id: ctx.params.id, name: 'John Doe' };
}
@Post('/users')
async createUser(ctx: IRequestContext<{ name: string; email: string }>) {
const body = await ctx.json();
return { id: 'new-id', ...body };
}
}
const server = new SmartServe({ port: 3000 });
server.register(UserController);
await server.start();
console.log('🚀 Server running at http://localhost:3000');
Lifecycle and controller ownership
server.register() keeps a durable controller declaration for that SmartServe
instance. stop() releases its active process-wide controller lease, OpenAPI
routes, WebSocket state, and runtime adapter resources. A later start()
reacquires the same declaration, so start() → stop() → start() preserves
the registered routes.
Controller registrations are identity-safe when several SmartServe instances use the same controller constructor: stopping one instance removes only its own lease and reveals the newest remaining owner. Releasing the final explicit lease does not implicitly construct a replacement controller.
Cleanup attempts every owned phase. Concurrent stop() calls share the same
work; a failed cleanup retains only unresolved resources for a later stop()
retry. Registering during start, stop, or an unresolved cleanup failure is
rejected. Application WebSocket close callbacks keep their documented isolated
logging behavior.

Decorators
Route Decorators
import { Route, Get, Post, Put, Delete, Patch, All } from '@push.rocks/smartserve';
@Route('/api/v1') // Base path for all routes in this controller
class ApiController {
@Get('/items') // GET /api/v1/items
listItems() {
return [{ id: 1, name: 'Item 1' }];
}
@Get('/items/:id') // GET /api/v1/items/:id
getItem(ctx: IRequestContext) {
return { id: ctx.params.id };
}
@Post('/items') // POST /api/v1/items
async createItem(ctx: IRequestContext<{ name: string }>) {
const body = await ctx.json();
return { created: body.name };
}
@Put('/items/:id') // PUT /api/v1/items/:id
async updateItem(ctx: IRequestContext) {
const body = await ctx.json();
return { updated: ctx.params.id, ...body };
}
@Delete('/items/:id') // DELETE /api/v1/items/:id
deleteItem(ctx: IRequestContext) {
return { deleted: ctx.params.id };
}
@All('/webhook') // Matches ALL HTTP methods
handleWebhook(ctx: IRequestContext) {
return { method: ctx.method };
}
}
Guards (Authentication/Authorization)
Guards protect routes by returning true (allow) or false (reject with 403):
import { Route, Get, Guard, hasBearerToken, type IRequestContext } from '@push.rocks/smartserve';
// Custom guard function
const isAuthenticated = (ctx: IRequestContext) => {
return ctx.headers.has('Authorization');
};
const isAdmin = (ctx: IRequestContext) => {
return ctx.headers.get('X-Role') === 'admin';
};
@Route('/admin')
@Guard(isAuthenticated)
@Guard(isAdmin) // Multiple guards - all must pass
class AdminController {
@Get('/dashboard')
dashboard() {
return { admin: true };
}
// Method-level guard (runs after class guards)
@Get('/super-secret')
@Guard((ctx) => ctx.headers.get('X-Super') === 'yes')
superSecret() {
return { level: 'super-secret' };
}
}
// Built-in utility guards
@Route('/protected')
@Guard(hasBearerToken()) // Requires Authorization: Bearer <token>
class ProtectedController {
@Get('/data')
getData() {
return { protected: true };
}
}
Transforms (Response Modification)
Transforms modify the response before sending:
import { Route, Get, Transform, wrapSuccess, addTimestamp } from '@push.rocks/smartserve';
// Custom transform
const addVersion = <T extends object>(data: T) => ({
...data,
apiVersion: '2.0',
});
@Route('/api')
@Transform(wrapSuccess) // Built-in: wraps in { success: true, data: ... }
class ApiController {
@Get('/info')
@Transform(addTimestamp) // Built-in: adds timestamp field
@Transform(addVersion) // Transforms stack
getInfo() {
return { name: 'MyAPI' };
}
// Response: { success: true, data: { name: 'MyAPI', timestamp: '...', apiVersion: '2.0' } }
}
Intercept (Full Control)
For complete control over request/response flow:
import { Route, Get, Intercept, type IRequestContext } from '@push.rocks/smartserve';
@Route('/api')
@Intercept({
// Runs BEFORE handler
request: async (ctx) => {
console.log(`📥 ${ctx.method} ${ctx.path}`);
// Return Response to short-circuit
if (ctx.headers.get('X-Block') === 'true') {
return new Response('Blocked', { status: 403 });
}
// Add data to state for handler access
ctx.state.requestTime = Date.now();
// Return void to continue with original context
},
// Runs AFTER handler
response: async (data, ctx) => {
const duration = Date.now() - (ctx.state.requestTime as number);
console.log(`📤 Response in ${duration}ms`);
return { ...data, processedIn: `${duration}ms` };
},
})
class LoggedController {
@Get('/data')
getData() {
return { items: [1, 2, 3] };
}
}
OpenAPI & Swagger
SmartServe includes first-class OpenAPI 3.1 support with automatic spec generation, Swagger UI, ReDoc, and request validation.
Documenting APIs
import {
SmartServe,
Route,

Post,
ApiOperation,
ApiParam,
ApiQuery,

} as const;
@Route('/api/users')
@ApiTag('Users')
class UserController {
@Get('/')
@ApiOperation({
summary: 'List all users',
description: 'Returns a paginated list of users',
})
@ApiQuery('page', {
description: 'Page number',
schema: { type: 'integer', minimum: 1, default: 1 },
})
@ApiQuery('limit', {
description: 'Items per page',
schema: { type: 'integer', minimum: 1, maximum: 100, default: 20 },
})
@ApiResponseBody(200, {
description: 'List of users',
schema: { type: 'array', items: UserSchema },
})
listUsers(ctx: IRequestContext) {
const page = ctx.query.page ?? '1';
const limit = ctx.query.limit ?? '20';
return { users: [], page: parseInt(page), limit: parseInt(limit) };
}
@Get('/:id')
@ApiOperation({ summary: 'Get user by ID' })
@ApiParam('id', {

schema: { type: 'string', format: 'uuid' },
})
@ApiResponseBody(200, { description: 'User found', schema: UserSchema })
@ApiResponseBody(404, { description: 'User not found' })
getUser(ctx: IRequestContext) {
return { id: ctx.params.id, name: 'John Doe', email: 'john@example.com' };
}
@Post('/')
@ApiOperation({ summary: 'Create a new user' })
@ApiRequestBody({
description: 'User data',
schema: CreateUserSchema,
})
@ApiResponseBody(201, { description: 'User created', schema: UserSchema })
@ApiResponseBody(400, { description: 'Validation error' })
@ApiSecurity('bearerAuth')
async createUser(ctx: IRequestContext<{ name: string; email: string }>) {
const body = await ctx.json();
return { id: 'new-uuid', name: body.name, email: body.email };
}
}
Request Validation
When you define @ApiRequestBody, @ApiParam, or @ApiQuery with schemas, SmartServe automatically validates incoming requests:
const server = new SmartServe({
port: 3000,
openapi: {
enabled: true,
info: {
title: 'My API',
version: '1.0.0',
description: 'A well-documented API',
},
validate: true, // 🔥 Enable automatic request validation
},
});
server.register(UserController);
await server.start();
// Invalid request → 400 Bad Request with details
// POST /api/users with { "name": "" }
// Response: { "error": "Validation failed", "source": "body", "details": [...] }
Automatic Type Coercion: Query and path parameters are automatically coerced to their schema types:
@Get('/items')
@ApiQuery('page', { schema: { type: 'integer', default: 1 } })
@ApiQuery('active', { schema: { type: 'boolean' } })
listItems(ctx: IRequestContext) {
// ctx.query.page is coerced to number (1)
// ctx.query.active is coerced to boolean
return { page: ctx.query.page, active: ctx.query.active };
}
Swagger UI & ReDoc
const server = new SmartServe({
port: 3000,
openapi: {
enabled: true,
info: {
title: 'My Awesome API',
version: '2.0.0',
description: 'API documentation with interactive testing',
contact: {
name: 'API Support',
email: 'support@example.com',
},
},
servers: [
{ url: 'http://localhost:3000', description: 'Development' },
{ url: 'https://api.example.com', description: 'Production' },
],
securitySchemes: {
bearerAuth: {
type: 'http',
scheme: 'bearer',
bearerFormat: 'JWT',
},
},
// Customize paths
specPath: '/openapi.json', // Default: /openapi.json
swaggerPath: '/docs', // Default: /docs
redocPath: '/redoc', // Default: /redoc
},
});
await server.start();
// 📖 Swagger UI: http://localhost:3000/docs
// 📕 ReDoc: http://localhost:3000/redoc
// 📄 OpenAPI: http://localhost:3000/openapi.json
Compression
SmartServe automatically compresses responses using Brotli or gzip based on client support:
const server = new SmartServe({
port: 3000,
compression: {
enabled: true, // Default: true
threshold: 1024, // Min bytes to compress (default: 1KB)
level: 6, // Compression level 1-11 for br, 1-9 for gzip
preferBrotli: true, // Prefer Brotli over gzip
},
});
Per-Route Compression Control
import { Route, Get, Compress, NoCompress } from '@push.rocks/smartserve';
@Route('/api')
class ApiController {
@Get('/large-data')
@Compress({ level: 9 }) // Force high compression
getLargeData() {
return { data: '...massive payload...' };
}
@Get('/already-compressed')
@NoCompress() // Skip compression (e.g., for pre-compressed content)
getCompressed() {
return someCompressedBuffer;
}
}
Pre-Compressed Static Files
Serve .br or .gz files automatically when available:
const server = new SmartServe({
port: 3000,
static: {
root: './dist',
precompressed: true, // Serve main.js.br instead of main.js
},
});
Static File Server
Serve static files with streaming, ETags, Range requests, and directory listing:
const server = new SmartServe({
port: 3000,
static: {
root: './public',
index: ['index.html', 'index.htm'],
dotFiles: 'deny', // 'allow' | 'deny' | 'ignore'
etag: true, // Generate ETags for caching
lastModified: true, // Add Last-Modified header
cacheControl: 'max-age=3600', // Or function: (path) => 'max-age=...'
extensions: ['.html'], // Try these extensions for extensionless URLs
precompressed: true, // Serve .br/.gz files when available
directoryListing: {
showHidden: false,
sortBy: 'name', // 'name' | 'size' | 'modified'
sortOrder: 'asc',
},
},
});
Or use the shorthand:
const server = new SmartServe({
port: 3000,
static: './public', // Uses sensible defaults
});
WebDAV Support
Mount the server as a network drive on macOS, Windows, or Linux:
const server = new SmartServe({
port: 8080,
webdav: {
root: '/path/to/files',
auth: (ctx) => {
// Optional: Basic authentication
const auth = ctx.headers.get('Authorization');
if (!auth) return false;
const [, credentials] = auth.split(' ');
const [user, pass] = atob(credentials).split(':');
return user === 'admin' && pass === 'secret';
},
locking: true, // Enable RFC 4918 exclusive write locks
},
});
await server.start();
// 💾 Connect: Finder → Go → Connect to Server → http://localhost:8080

HTTP Timeouts
The Node.js adapter can enforce independent socket inactivity, header, and complete-request deadlines:
const server = new SmartServe({
port: 3000,
connectionTimeout: 15_000,
headersTimeout: 10_000,
requestTimeout: 120_000,
});
Each configured value must be an integer from 1 through 2147483647 milliseconds. Bun and Deno currently reject these options at startup instead of silently ignoring a deadline they cannot enforce.
On Node.js, the Web Request.signal passed to handlers aborts when the client
disconnects, the request or response transport fails, or the server stops.
Request-body and streamed-response work receives the same cancellation. A
normally completed response leaves the signal un-aborted; requestTimeout
continues to mean Node's complete-request deadline rather than a handler timer.
WebSocket Support
WebSocket connections are handled natively across all runtimes:
const server = new SmartServe({
port: 3000,
websocket: {
maxPayloadBytes: 64 * 1024,
admit: (context) => {
const origin = context.request.headers.get('origin');
return origin === 'https://app.example.com';
},
onOpen: (peer) => {
console.log(`🔗 Connected: ${peer.id}`);
peer.send('Welcome!');
peer.tags.add('authenticated'); // Tag for filtering
},
onMessage: (peer, message) => {
console.log(`📨 ${message.text}`);
peer.send(`Echo: ${message.text}`);
},
onClose: (peer, code, reason) => {
console.log(`👋 Disconnected: ${peer.id}`);
},
onError: (peer, error) => {
console.error(`❌ Error: ${error.message}`);
},
},
});
admit runs before the WebSocket protocol upgrade on Node.js, Bun, and Deno.
Return false for a 403 rejection, return a Response for a custom rejection,
or return true/void to allow the connection. The request context exposes the
requested host, origin, path, headers, and URL, so applications can enforce
their transport boundary before a peer exists.
Set maxPayloadBytes to an integer from 1 through 2147483647 bytes to reject oversized messages
before TypedRouter JSON parsing or onMessage dispatch. The limit is
enforced by the native runtime where supported and by SmartServe before
application dispatch on every runtime. SmartServe sends WebSocket code 1009
when the runtime exposes the oversized message; a native runtime may terminate
the message before an application close frame can be sent. Omitting the option
preserves the runtime's existing default.
Strict Request Authority
Enable strict authority validation when host identity is a security boundary:
const server = new SmartServe({
port: 3000,
authorityValidation: 'strict',
});
Strict mode requires exactly one syntactically valid Host authority before
SmartServe constructs the request URL. Duplicate, merged, padded, malformed,
userinfo-bearing, path-bearing, and out-of-range-port authorities receive
400 Bad Request. The parsed hostname and effective port must also match the
request URL authority. The default legacy mode preserves historical behavior.
parseRequestAuthority(rawHostValues) exposes the same parser for boundary
code that has access to raw header values. It returns
IParsedRequestAuthority and throws InvalidRequestAuthorityError when the
authority is missing, ambiguous, or malformed.
WebSocket Heartbeat
SmartServe sends WebSocket control-frame pings by default on Node.js and Bun to keep idle proxy paths active and to close stale peers that stop responding with pongs.
const server = new SmartServe({
port: 3000,
websocket: {
heartbeat: {
intervalMs: 30_000, // default
timeoutMs: 15_000, // default, must be lower than intervalMs
},
onMessage: (peer, message) => {
peer.send(`Echo: ${message.text}`);
},
},
});
Set heartbeat: false to disable automatic pings. The heartbeat option also accepts an optional payload string or Uint8Array for ping frames. The Deno adapter does not currently support control-frame heartbeat; explicitly enabling heartbeat on Deno throws during startup.
Generic Raw-Frame Transport
Bind a generic owner when an integration needs normalized binary messages while TypedRouter continues to handle text RPC messages:
import {
SmartServe,
type IWebSocketTransportOwner,
} from '@push.rocks/smartserve';
import { TypedRouter } from '@api.global/typedrequest';
const typedRouter = new TypedRouter();
const priorityFrames = [{ type: 'text' as const, text: 'ready' }];
const binaryFrames = [
{ type: 'binary' as const, data: new Uint8Array([1, 2, 3]) },
];
const transportOwner: IWebSocketTransportOwner = {
onOpen: (peer) => {
peer.rawFrameScheduler?.wake();
},
onFrame: (_peer, frame) => {
if (frame.type === 'binary') {
console.log(frame.data, frame.size);
}
},
pullPriorityFrame: () => priorityFrames.shift(),
pullBinaryFrame: () => binaryFrames.shift(),
onOutboundFrameSettled: (_peer, frame, settlement) => {
console.log(frame.type, settlement.status, settlement.bufferedAmount);
},
onTypedResponseSettled: (_peer, response, settlement) => {
console.log(response.correlation?.id, settlement.status);
},
};
const server = new SmartServe({
port: 3000,
websocket: {
typedRouter,
transportOwner,
},
});
transportOwner and resolveTransportOwner(context) are mutually exclusive.
The resolver runs once before upgrade, and returning undefined rejects the
upgrade with 404. The selected owner, peer object, and per-peer scheduler stay
exact for that physical connection. Owner open, frame, error, and close
callbacks are invoked in native event order; close is delivered once. Raw-frame
listeners, owner frame callbacks, queue pulls, and settlement callbacks are
synchronous enqueue/accounting boundaries. SmartServe catches synchronous
throws and observes an accidentally returned Promise without awaiting it.
onTypedResponseSettled receives the exact TypedRouter response envelope after
its text frame reaches the runtime's canonical sent, accepted, failed, or
rejected settlement. TypedRequest 8 wire requests must carry a fresh,
non-empty requestInstanceId. SmartServe rejects malformed envelopes before
TypedRouter routing and serializes a response only when its method, correlation
ID, and request instance ID exactly match the request.
Legacy onConnectionOpen, onOpen, onError, and onClose Promise returns are
also observed but never awaited by adapter dispatch, preserving non-blocking
WebSocket lifecycle behavior.
TypedRouter text requests start in normalized text-frame arrival order and may complete independently by correlation. Raw frames therefore continue to reach the owner during long-running handlers. Closing the peer cancels tracked response wrappers, suppresses late responses, and still observes late handler rejections so they cannot become unhandled rejections.
Incoming Node.js, Bun, and Deno payloads are normalized to discriminated text
or binary frames. Binary messages are never passed to TypedRouter JSON parsing.
Use websocket.onRawFrame or server.subscribeWebSocketRawFrame(listener) for
an additive synchronous listener; the subscription method returns an
unsubscribe function. Deno sets binaryType = "arraybuffer"; an unexpected
Blob is rejected instead of creating an asynchronous normalization backlog.
Each peer.rawFrameScheduler.wake() requests one turn. A turn pulls at most
WEBSOCKET_RAW_PRIORITY_FRAME_MAX_PER_TURN priority text/ping/pong messages,
then at most one binary message, and stops. The owner uses settlement and
bufferedAmount to decide whether and when to wake again. Explicitly requested
follow-up turns start in a later macrotask. Repeated wakes before a turn starts,
or repeated wakes while one turn is running, coalesce into at most one pending
follow-up turn. Binary messages larger than
WEBSOCKET_RAW_BINARY_FRAME_MAX_BYTES (32 KiB) settle as rejected and are not
split. The owner retains its queues and accounting and receives sent,
accepted, failed, or rejected settlement. Bun resumes after its native
drain callback only when an already-requested turn encountered backpressure;
Deno reports native acceptance and bufferedAmount but cannot confirm network
delivery or send explicit ping/pong control frames.
TypedRouter for Type-Safe RPC
Use @api.global/typedrequest for type-safe WebSocket communication:
import { TypedRouter } from '@api.global/typedrequest';
const typedRouter = new TypedRouter();
typedRouter.addTypedHandler(MyTypedRequest, async (request, tools) => {
return {
result: 'processed',
peerId: tools.localData.peer.id,
};
});
const server = new SmartServe({
port: 3000,
websocket: {
typedRouter, // Handles message routing automatically
onConnectionOpen: (peer) => {
peer.tags.add('subscriber');
},
},
});
// Broadcast to tagged connections
server.broadcastWebSocketByTag('subscriber', { event: 'update' });
When typedRouter is configured, SmartServe supplies the accepted peer as
server-owned tools.localData.peer for every handler. Caller-supplied
localData is discarded, so a network client cannot forge the peer or its
request context. SmartServe does not derive handler cancellation from wire data;
cancellation-aware transports such as TypedSocket own trusted incoming request
signal registration on the selected router.
Resolve a different router for each accepted connection when one listener serves isolated hosts or protocol surfaces:
const server = new SmartServe({
port: 3000,
authorityValidation: 'strict',
websocket: {
admit: (context) => allowedOrigins.has(context.headers.get('origin') ?? ''),
resolveTypedRouter: (context) => {
if (context.url.hostname === 'public.example.com') return publicRouter;
if (context.url.hostname === 'admin.example.com') return adminRouter;
return undefined;
},
},
});
The resolver runs once after admission and before upgrade. SmartServe binds the
selected router to that peer for its full lifetime; returning undefined
rejects the upgrade with 404. resolveTypedRouter is mutually exclusive with
typedRouter and onMessage. Connection registry, connection lifecycle,
tag-query, and broadcast APIs work whenever websocket is configured, including
plain hooks, static or resolved TypedRouter, and generic transport-owner modes.
The accepted peer exposes that exact immutable selection as
peer.routingSurface; it is undefined when the connection has no TypedRouter.
Transport owners can use object identity against this property when authorizing
separately routed responses.
HTTPS/TLS
Enable HTTPS with certificate configuration:
import * as fs from 'fs';
import {
SmartServe,
validateNodeTlsConfig,
type ITLSConfig,
} from '@push.rocks/smartserve';
const tls: ITLSConfig = {
cert: fs.readFileSync('./cert.pem'),
key: fs.readFileSync('./key.pem'),
ca: fs.readFileSync('./ca.pem'), // Optional: CA chain
minVersion: 'TLSv1.2', // Optional: minimum TLS version
passphrase: 'optional-key-passphrase',
};
validateNodeTlsConfig(tls);
const server = new SmartServe({
port: 443,
tls,
});
validateNodeTlsConfig() checks Node.js ALPN identifier limits and parses the
certificate, private key, optional CA, passphrase, minimum TLS version, and
secure-context input without constructing a server or listener. This explicit
preflight is useful when a caller must reject TLS input before creating other
lifecycle resources. Bun and Deno keep their runtime-specific TLS semantics.
Error Handling
Built-in HTTP error classes with factory methods:
import { HttpError, type IRequestContext } from '@push.rocks/smartserve';
@Route('/api')
class ApiController {
@Get('/users/:id')
async getUser(ctx: IRequestContext) {
const user = await findUser(ctx.params.id);
if (!user) {
throw HttpError.notFound('User not found', { id: ctx.params.id });
}
return user;
}
}
// Available factory methods:
HttpError.badRequest(message, details); // 400
HttpError.unauthorized(message, details); // 401
HttpError.forbidden(message, details); // 403
HttpError.notFound(message, details); // 404
HttpError.conflict(message, details); // 409
HttpError.internal(message, details); // 500
Global Error Handler
const server = new SmartServe({
port: 3000,
onError: (error, request) => {
console.error('💥 Server error:', error);
// Return custom error response
return new Response(
JSON.stringify({ error: 'Something went wrong', requestId: crypto.randomUUID() }),
{ status: 500, headers: { 'Content-Type': 'application/json' } }
);
},
});
Request Context
Every handler receives a typed request context:
interface IRequestContext<TBody = unknown> {
request: Request; // Original Request (body never consumed by framework)
params: Record<string, string>; // URL path parameters (/users/:id → { id: '123' })
query: Record<string, string>; // Query string (?page=1 → { page: '1' })
headers: Headers; // Request headers
path: string; // Matched route path
method: THttpMethod; // GET, POST, PUT, DELETE, etc.
url: URL; // Full URL object
runtime: 'node' | 'deno' | 'bun';
state: Record<string, unknown>; // Per-request state (share data between interceptors)
// 🔥 Lazy body parsing (cached after first call)
json(): Promise<TBody>; // Parse as JSON (typed!)
text(): Promise<string>; // Parse as text
arrayBuffer(): Promise<ArrayBuffer>;
formData(): Promise<FormData>;
}
Lazy Body Parsing: The request body is only consumed when you call json(), text(), etc. This allows raw access to ctx.request for cases like webhook signature verification:
@Post('/webhook')
async handleWebhook(ctx: IRequestContext) {
// Get raw body for signature verification
const rawBody = await ctx.request.text();
const signature = ctx.headers.get('X-Signature');
if (!verifyHmac(rawBody, signature)) {
throw HttpError.unauthorized('Invalid signature');
}
// Parse the body manually
const payload = JSON.parse(rawBody);
return { processed: true };
}
Custom Request Handler
Bypass decorator routing entirely for low-level control:
const server = new SmartServe({ port: 3000 });
server.setHandler(async (request, connectionInfo) => {
const url = new URL(request.url);
if (url.pathname === '/health') {
return new Response('OK', { status: 200 });
}
if (url.pathname.startsWith('/api')) {

Runtime Detection
SmartServe automatically detects and optimizes for the current runtime:
const instance = await server.start();
console.log(instance.runtime); // 'node' | 'deno' | 'bun'
console.log(instance.port); // 3000
console.log(instance.hostname); // '0.0.0.0'
console.log(instance.secure); // true if TLS enabled
// Server statistics
const stats = instance.stats();
console.log(stats.uptime); // Seconds since start
console.log(stats.requestsTotal); // Total requests handled
console.log(stats.requestsActive); // Currently processing
