# Node.js Adapter for Hono
This adapter `@hono/node-server` allows you to run your Hono application on Node.js.
Initially, Hono wasn't designed for Node.js, but with this adapter, you can now use Hono on Node.js.
It utilizes web standard APIs implemented in Node.js version 18 or higher.
## Benchmarks
Hono is 3.5 times faster than Express.
Express:
```txt
$ bombardier -d 10s --fasthttp http://localhost:3000/
Statistics Avg Stdev Max
Reqs/sec 16438.94 1603.39 19155.47
Latency 7.60ms 7.51ms 559.89ms
HTTP codes:
1xx - 0, 2xx - 164494, 3xx - 0, 4xx - 0, 5xx - 0
others - 0
Throughput: 4.55MB/s
```
Hono + `@hono/node-server`:
```txt
$ bombardier -d 10s --fasthttp http://localhost:3000/
Statistics Avg Stdev Max
Reqs/sec 58296.56 5512.74 74403.56
Latency 2.14ms 1.46ms 190.92ms
HTTP codes:
1xx - 0, 2xx - 583059, 3xx - 0, 4xx - 0, 5xx - 0
others - 0
Throughput: 12.56MB/s
```
## Requirements
It works on Node.js versions greater than 18.x. The specific required Node.js versions are as follows:
- 18.x => 18.14.1+
- 19.x => 19.7.0+
- 20.x => 20.0.0+
Essentially, you can simply use the latest version of each major release.
## Installation
You can install it from the npm registry with `npm` command:
```sh
npm install @hono/node-server
```
Or use `yarn`:
```sh
yarn add @hono/node-server
```
## Usage
Just import `@hono/node-server` at the top and write the code as usual.
The same code that runs on Cloudflare Workers, Deno, and Bun will work.
```ts
import { serve } from '@hono/node-server'
import { Hono } from 'hono'
const app = new Hono()
app.get('/', (c) => c.text('Hono meets Node.js'))
serve(app, (info) => {
console.log(`Listening on http://localhost:${info.port}`) // Listening on http://localhost:3000
})
```
For example, run it using `ts-node`. Then an HTTP server will be launched. The default port is `3000`.
```sh
ts-node ./index.ts
```
Open `http://localhost:3000` with your browser.
## Options
### `port`
```ts
serve({
fetch: app.fetch,
port: 8787, // Port number, default is 3000
})
```
### `createServer`
```ts
import { createServer } from 'node:https'
import fs from 'node:fs'
//...
serve({
fetch: app.fetch,
createServer: createServer,
serverOptions: {
key: fs.readFileSync('test/fixtures/keys/agent1-key.pem'),
cert: fs.readFileSync('test/fixtures/keys/agent1-cert.pem'),
},
})
```
### `overrideGlobalObjects`
The default value is `true`. The Node.js Adapter rewrites the global Request/Response and uses a lightweight Request/Response to improve performance. If you don't want to do that, set `false`.
```ts
serve({
fetch: app.fetch,
overrideGlobalObjects: false,
})
```
### `autoCleanupIncoming`
The default value is `true`. The Node.js Adapter automatically cleans up (explicitly call `destroy()` method) if application is not finished to consume the incoming request. If you don't want to do that, set `false`.
If the application accepts connections from arbitrary clients, this cleanup must be done otherwise incomplete requests from clients may cause the application to stop responding. If your application only accepts connections from trusted clients, such as in a reverse proxy environment and there is no process that returns a response without reading the body of the POST request all the way through, you can improve performance by setting it to `false`.
```ts
serve({
fetch: app.fetch,
autoCleanupIncoming: false,
})
```
## Middleware
Most built-in middleware also works with Node.js.
Read [the documentation](https://hono.dev/middleware/builtin/basic-auth) and use the Middleware of your liking.
```ts
import { serve } from '@hono/node-server'
import { Hono } from 'hono'
import { prettyJSON } from 'hono/pretty-json'
const app = new Hono()
app.get('*', prettyJSON())
app.get('/', (c) => c.json({ 'Hono meets': 'Node.js' }))
serve(app)
```
## Serve Static Middleware
Use Serve Static Middleware that has been created for Node.js.
```ts
import { serveStatic } from '@hono/node-server/serve-static'
//...
app.use('/static/*', serveStatic({ root: './' }))
```
If using a relative path, `root` will be relative to the current working directory from which the app was started.
This can cause confusion when running your application locally.
Imagine your project structure is:
```
my-hono-project/
src/
index.ts
static/
index.html
```
Typically, you would run your app from the project's root directory (`my-hono-project`),
so you would need the following code to serve the `static` folder:
```ts
app.use('/static/*', serveStatic({ root: './static' }))
```
Notice that `root` here is not relative to `src/index.ts`, rather to `my-hono-project`.
### Options
#### `rewriteRequestPath`
If you want to serve files in `./.foojs` with the request path `/__foo/*`, you can write like the following.
```ts
app.use(
'/__foo/*',
serveStatic({
root: './.foojs/',
rewriteRequestPath: (path: string) => path.replace(/^\/__foo/, ''),
})
)
```
#### `onFound`
You can specify handling when the requested file is found with `onFound`.
```ts
app.use(
'/static/*',
serveStatic({
// ...
onFound: (_path, c) => {
c.header('Cache-Control', `public, immutable, max-age=31536000`)
},
})
)
```
#### `onNotFound`
The `onNotFound` is useful for debugging. You can write a handle for when a file is not found.
```ts
app.use(
'/static/*',
serveStatic({
root: './non-existent-dir',
onNotFound: (path, c) => {
console.log(`${path} is not found, request to ${c.req.path}`)
},
})
)
```
#### `precompressed`
The `precompressed` option checks if files with extensions like `.br` or `.gz` are available and serves them based on the `Accept-Encoding` header. It prioritizes Brotli, then Zstd, and Gzip. If none are available, it serves the original file.
```ts
app.use(
'/static/*',
serveStatic({
precompressed: true,
})
)
```
## ConnInfo Helper
You can use the [ConnInfo Helper](https://hono.dev/docs/helpers/conninfo) by importing `getConnInfo` from `@hono/node-server/conninfo`.
```ts
import { getConnInfo } from '@hono/node-server/conninfo'
app.get('/', (c) => {
const info = getConnInfo(c) // info is `ConnInfo`
return c.text(`Your remote address is ${info.remote.address}`)
})
```
## Accessing Node.js API
You can access the Node.js API from `c.env` in Node.js. For example, if you want to specify a type, you can write the following.
```ts
import { serve } from '@hono/node-server'
import type { HttpBindings } from '@hono/node-server'
import { Hono } from 'hono'
const app = new Hono<{ Bindings: HttpBindings }>()
app.get('/', (c) => {
return c.json({
remoteAddress: c.env.incoming.socket.remoteAddress,
})
})
serve(app)
```
The APIs that you can get from `c.env` are as follows.
```ts
type HttpBindings = {
incoming: IncomingMessage
outgoing: ServerResponse
}
type Http2Bindings = {
incoming: Http2ServerRequest
outgoing: Http2ServerResponse
}
```
## Direct response from Node.js API
You can directly respond to the client from the Node.js API.
In that case, the response from Hono should be ignored, so return `RESPONSE_ALREADY_SENT`.
> [!NOTE]
> This feature can be used when migrating existing Node.js applications to Hono, but we recommend using Hono's API for new applications.
```ts
import { serve } from '@hono/node-server'
import type { HttpBindings } from '@hono/node-server'
import { RESPONSE_ALREADY_SENT } from '@hono/node-server/utils/response'
import { Hono } from 'hono'
const app = new Hono<{ Bindings: HttpBindings }>()
app.get('/', (c) => {
const { outgoing } = c.env
outgoing.writeHead(200, { 'Content-Type': 'text/plain' })
outgoing.end('Hello World\n')
return RESPONSE_ALREADY_SENT
})
serve(app)
```
## Listen to a UNIX domain socket
You can configure the HTTP server to listen to a UNIX domain socket instead of a TCP port.
```ts
import { createAdaptorServer } from '@hono/node-server'
// ...
const socketPath ='/tmp/example.sock'
const server = createAdaptorServer(app)
server.listen(socketPath, () => {
console.log(`Listening on ${socketPath}`)
})
```

# @jridgewell/sourcemap-codec
Encode/decode the `mappings` property of a [sourcemap](https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit).
## Why?
Sourcemaps are difficult to generate and manipulate, because the `mappings` property the part that actually links the generated code back to the original source is encoded using an obscure method called [Variable-length quantity](https://en.wikipedia.org/wiki/Variable-length_quantity). On top of that, each segment in the mapping contains offsets rather than absolute indices, which means that you can't look at a segment in isolation you have to understand the whole sourcemap.
This package makes the process slightly easier.
## Installation
```bash
npm install @jridgewell/sourcemap-codec
```
## Usage
```js
import { encode, decode } from '@jridgewell/sourcemap-codec';
var decoded = decode( ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
assert.deepEqual( decoded, [
// the first line (of the generated code) has no mappings,
// as shown by the starting semi-colon (which separates lines)
[],
// the second line contains four (comma-separated) segments
[
// segments are encoded as you'd expect:
// [ generatedCodeColumn, sourceIndex, sourceCodeLine, sourceCodeColumn, nameIndex ]
// i.e. the first segment begins at column 2, and maps back to the second column
// of the second line (both zero-based) of the 0th source, and uses the 0th
// name in the `map.names` array
[ 2, 0, 2, 2, 0 ],
// the remaining segments are 4-length rather than 5-length,
// because they don't map a name
[ 4, 0, 2, 4 ],
[ 6, 0, 2, 5 ],
[ 7, 0, 2, 7 ]
],
// the final line contains two segments
[
[ 2, 1, 10, 19 ],
[ 12, 1, 11, 20 ]
]
]);
var encoded = encode( decoded );
assert.equal( encoded, ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
```

## Overview
The Model Context Protocol allows applications to provide context for LLMs in a standardized way, separating the concerns of providing context from the actual LLM interaction. This TypeScript SDK implements
[the full MCP specification](https://modelcontextprotocol.io/specification/draft), making it easy to:
- Create MCP servers that expose resources, prompts and tools
- Build MCP clients that can connect to any MCP server
- Use standard transports like stdio and Streamable HTTP
## Installation
```bash
npm install @modelcontextprotocol/sdk zod
```
This SDK has a **required peer dependency** on `zod` for schema validation. The SDK internally imports from `zod/v4`, but maintains backwards compatibility with projects using Zod v3.25 or later. You can use either API in your code by importing from `zod/v3` or `zod/v4`:
## Quick Start
To see the SDK in action end-to-end, start from the runnable examples in `src/examples`:
1. **Install dependencies** (from the SDK repo root):
```bash
npm install
```
2. **Run the example Streamable HTTP server**:
```bash
npx tsx src/examples/server/simpleStreamableHttp.ts
```
3. **Run the interactive client in another terminal**:
```bash
npx tsx src/examples/client/simpleStreamableHttp.ts
```
This pair of examples demonstrates tools, resources, prompts, sampling, elicitation, tasks and logging. For a guided walkthrough and variations (stateless servers, JSON-only responses, SSE compatibility, OAuth, etc.), see [docs/server.md](docs/server.md) and
[docs/client.md](docs/client.md).
## Core Concepts
### Servers and transports
An MCP server is typically created with `McpServer` and connected to a transport such as Streamable HTTP or stdio. The SDK supports:
- **Streamable HTTP** for remote servers (recommended).
- **HTTP + SSE** for backwards compatibility only.
- **stdio** for local, process-spawned integrations.
Runnable server examples live under `src/examples/server` and are documented in [docs/server.md](docs/server.md).
### Tools, resources, prompts
- **Tools** let LLMs ask your server to take actions (computation, side effects, network calls).
- **Resources** expose read-only data that clients can surface to users or models.
- **Prompts** are reusable templates that help users talk to models in a consistent way.
The detailed APIs, including `ResourceTemplate`, completions, and display-name metadata, are covered in [docs/server.md](docs/server.md#tools-resources-and-prompts), with runnable implementations in [`simpleStreamableHttp.ts`](src/examples/server/simpleStreamableHttp.ts).
### Capabilities: sampling, elicitation, and tasks
The SDK includes higher-level capabilities for richer workflows:
- **Sampling**: server-side tools can ask connected clients to run LLM completions.
- **Form elicitation**: tools can request non-sensitive input via structured forms.
- **URL elicitation**: servers can ask users to complete secure flows in a browser (e.g., API key entry, payments, OAuth).
- **Tasks (experimental)**: long-running tool calls can be turned into tasks that you poll or resume later.
Conceptual overviews and links to runnable examples are in:
- [docs/capabilities.md](docs/capabilities.md)
Key example servers include:
- [`toolWithSampleServer.ts`](src/examples/server/toolWithSampleServer.ts)
- [`elicitationFormExample.ts`](src/examples/server/elicitationFormExample.ts)
- [`elicitationUrlExample.ts`](src/examples/server/elicitationUrlExample.ts)
### Clients
The high-level `Client` class connects to MCP servers over different transports and exposes helpers like `listTools`, `callTool`, `listResources`, `readResource`, `listPrompts`, and `getPrompt`.
Runnable clients live under `src/examples/client` and are described in [docs/client.md](docs/client.md), including:
- Interactive Streamable HTTP client ([`simpleStreamableHttp.ts`](src/examples/client/simpleStreamableHttp.ts))
- Streamable HTTP client with SSE fallback ([`streamableHttpWithSseFallbackClient.ts`](src/examples/client/streamableHttpWithSseFallbackClient.ts))
- OAuth-enabled clients and polling/parallel examples
### Node.js Web Crypto (globalThis.crypto) compatibility
Some parts of the SDK (for example, JWT-based client authentication in `auth-extensions.ts` via `jose`) rely on the Web Crypto API exposed as `globalThis.crypto`.
See [docs/faq.md](docs/faq.md) for details on supported Node.js versions and how to polyfill `globalThis.crypto` when running on older Node.js runtimes.
## Examples
The SDK ships runnable examples under `src/examples`. Use these tables to find the scenario you care about and jump straight to the corresponding code and docs.
