 # RxDB Server
 
-The RxDB Server Plugin makes it possible to spawn a server on top of a RxDB database that offers multiple types of endpoints for various usages. It can spawn basic CRUD REST endpoints or even realtime replication endpoints that can be used by the client devices to replicate data. The RxServer plugin is designed to be used in Node.js but you can also use it in Deno, Bun or the Electron "main" process.

The RxServer plugin is designed to be used in Node.js but you can also use it in Deno, Bun or the Electron "main" process. You can use it either as a **standalone server** or add it on top of an **exisiting http server** (like express) in nodejs.
 
 **NOTICE:** The server plugin is in beta mode and the API might be changed without a major RxDB release.

+## Building a custom worker
+
+To build a custom `worker.js` file, check out the webpack config at the [worker](./rx-storage-worker.md#building-a-custom-worker) documentation. Any worker file form the worker storage can also be used in a shared worker because `exposeWorkerRxStorage` detects where it runs and exposes the correct messaging endpoints.
+
 ## Passing in a SharedWorker instance
 
 Instead of setting an url as `workerInput`, you can also specify a function that returns a new `SharedWorker` instance when called. This is mostly used when you have a custom worker file and dynamically import it.

+## Building a custom worker
+
+The easiest way to bundle a custom `worker.js` file is by using webpack. Here is the webpack-config that is also used for the prebuild workers:
+
+```ts
+// webpack.config.js
+const path = require('path');
+const TerserPlugin = require('terser-webpack-plugin');
+const projectRootPath = path.resolve(
+    __dirname,
+    '../../' // path from webpack-config to the root folder of the repo
+);
+const babelConfig = require(path.join(projectRootPath, 'babel.config'));
+const baseDir = './dist/workers/'; // output path
+module.exports = {
+    target: 'webworker',
+    entry: {
+        'my-custom-worker': baseDir + 'my-custom-worker.js',
