## Installation

```
npm install sync-rpc --save
```

## Usage

### worker.js

```js
function init(connection) {
  // you can setup any connections you need here
  return function (message) {
    // Note how even though we return a promise, the resulting rpc client will be synchronous
    return Promise.resolve('sent ' + message + ' to ' + connection);
  }
}
module.exports = init;
```

```js
const assert = require('assert');
const rpc = require('sync-rpc');

const client = rpc(__dirname + '/../test-worker.js', 'My Server');

const result = client('My Message');

assert(result === 'sent My Message to My Server');
```
