# 설치 가이드

1. 코드 내려받기

git clone https://github.com/crossbario/autobahn-js

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd autobahn-js

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm install autobahn

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

이 레포의 README에 적힌 실제 명령어를 그대로 가져왔습니다.

**Autobahn**|JS is a subproject of the [Autobahn project](https://autobahn.readthedocs.io) and provides an open-source implementation of the **[Web Application Messaging Protocol V2](http://wamp.ws/)** in JavaScript under the [MIT license](/LICENSE).

WAMP provides asynchronous **Remote Procedure Calls** and **Publish & Subscribe** for applications in *one* protocol running over [WebSocket](http://tools.ietf.org/html/rfc6455) (and fallback transports for old browsers).

**Autobahn**|JS runs on both **Web browsers** and **[Node.js](http://nodejs.org/)**.

## Platform Requirements

**Autobahn**|JS targets:

- **Node.js 22+** (uses native WebSocket, no external dependencies)
- **Modern browsers**: Chrome, Firefox, Edge, Safari (all current versions)

For older Node.js versions (< 22), use AutobahnJS v20.x which includes the `ws` library.

## What can I do with this stuff?

**Autobahn|JS** makes **distributed, realtime Web applications easy**: it provides the infrastructure for both **distributing live updates** to all connected clients (using the PubSub messaging pattern) and for **calling remote procedures** in different backend components (using RPC).

It is ideal for distributed, multi-client and server applications, such as multi-user database-drive business applications, real-time charts, sensor networks (IoT), instant messaging or MMOGs (massively multi-player online games).

The protocol that **Autobahn|JS** uses, WAMP, enables application architectures with application code **distributed freely across processes and devices** according to functional aspects. All WAMP clients are equal in that they can publish events and subscribe to them, can offer a procedure for remote calling and call remote procedures.

Since WAMP implementations exist for **multiple languages**, this extends beyond JavaScript clients: WAMP applications can be polyglot. Application components can be implemented in a language and run on a device which best fit the particular use case. Applications can span the range from embedded IoT sensors right to mobile clients or the browser - using the same protocol.

## Show me some code

The following example implements all four roles that **Autobahn**|JS offers

* Publisher
 * Subscriber
 * Caller (calls a remote procedure)
 * Callee (offers a remote procedure)

**The code runs unaltered in the browser or Node.js!**

```javascript
try {
   // for Node.js
   var autobahn = require('autobahn');
} catch (e) {
   // for browsers (where AutobahnJS is available globally)
}

var connection = new autobahn.Connection({url: 'ws://127.0.0.1:9000/', realm: 'realm1'});

connection.onopen = function (session) {

// 1) subscribe to a topic
   function onevent(args) {
      console.log("Event:", args[0]);
   }
   session.subscribe('com.myapp.hello', onevent);

// 2) publish an event
   session.publish('com.myapp.hello', ['Hello, world!']);

// 3) register a procedure for remoting
   function add2(args) {
      return args[0] + args[1];
   }
   session.register('com.myapp.add2', add2);

// 4) call a remote procedure
   session.call('com.myapp.add2', [2, 3]).then(
      function (res) {
         console.log("Result:", res);
      }
   );
};

connection.open();
```

Features
--------

* supports WAMP v2, works with any WAMP server
* works both in the browser and Node.js
* provides asynchronous RPC and PubSub messaging patterns
* uses WebSocket or HTTP long-poll as transport
* easy to use Promise-based API
* pluggable promises/deferreds: uses [when.js](https://github.com/cujojs/when) (built-in) with progress support for WAMP progressive calls
* minimal dependencies (when.js for promises, CryptoJS for WAMP-CRA auth)
* small size (~250kB source, ~110kB minified, ~35kB gzipped)
* Open-Source (MIT License)

## Get it

### Browser Development

The *latest* built release of AutobahnJS can be retrieved by cloning [this](https://github.com/crossbario/autobahn-js-browser) repository. You can then host the library wherever you need to.

This also contains a complete history of previous releases and can be used with **[Bower](http://bower.io/)**. To install:

bower install autobahn

### Node.js Development

AutobahnJS is available via npm [here](https://www.npmjs.org/package/autobahn). To install:

```console
npm install autobahn
```

#### Supported Node.js Versions

AutobahnJS is tested and supported on the following Node.js versions:

| Version | Status | Support Until |
|---------|--------|---------------|
| 22.x | Maintenance LTS | Apr 2027 |
| 24.x | **Active LTS** "Krypton" | Apr 2028 |
| 25.x | Current | — |

**Recommendation:** Use Node.js 24.x (Active LTS) for production deployments.

For the latest Node.js release schedule, see [nodejs.org/about/previous-releases](https://nodejs.org/en/about/previous-releases).

#### WebSocket Support

Node.js 22+ includes native WebSocket support. AutobahnJS uses this native implementation directly—no external WebSocket library is required.

#### Quick Check

Verify your installation:

```console
node -e "var autobahn = require('autobahn'); console.log('AutobahnJS version:', autobahn.version);"
```

* [a basic introduction to programming with Autobahn|JS](/doc/programming.md)
* [a list of all examples in this repo](/doc/examples.md)
* [a full API reference](/doc/reference.md)

## Acknowledgements

**Autobahn**|JS includes code from the following open-source projects

* [when.js](https://github.com/cujojs/when) — Promise/A+ implementation with progress support
  * [CryptoJS](http://code.google.com/p/crypto-js/) — Cryptographic functions for WAMP-CRA

Special thanks to the [Coders with an Unhealthy Javascript Obsession](http://cujojs.com/) for creating *when.js - A lightweight Promise and when() implementation, plus other async goodies.*

**Historical note:** Prior to v26.x, AutobahnJS used the excellent [ws](https://github.com/websockets/ws) library for WebSocket support in Node.js. With Node.js 22+ providing native WebSocket, this dependency is no longer needed.
