`@univerjs/rpc` provides a browser-friendly RPC layer for communicating between the main thread and workers or other message-based runtimes.

## Package Overview

| Package | UMD global | CSS | Locales | Facade entry |
| --- | --- | :---: | :---: | :---: |
| `@univerjs/rpc` | `UniverRpc` | No | No | No |

## Installation

```sh
pnpm add @univerjs/rpc
# or
npm install @univerjs/rpc
```

Keep all `@univerjs/*` packages on the same version.

## Usage

```ts
import { UniverRPCMainThreadPlugin } from '@univerjs/rpc';

const worker = new Worker(new URL('./worker.js', import.meta.url), { type: 'module' });
univer.registerPlugin(UniverRPCMainThreadPlugin, { workerURL: worker });
univer.onDispose(() => worker.terminate());
```

The referenced worker module must create its own Univer instance and register `UniverRPCWorkerThreadPlugin`; see the [browser worker example](../../examples/src/sheets-mobile/worker.ts).

Exported plugin classes:

- `UniverRPCMainThreadPlugin`
- `UniverRPCWorkerThreadPlugin`
