You just broke the old code on 0.39:

```
$ npm start

> sojsclient-example@1.0.0 start /home/jsclient
> npm run bundle && npm run serve


> jsclient-example@1.0.0 bundle /home/jsclient
> browserify src/index.js > public/bundle.js


/home/jsclient/node_modules/ky-universal/browser.js:1
export {default} from 'ky';
^
ParseError: 'import' and 'export' may appear only with 'sourceType: module'
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! jsclient-example@1.0.0 bundle: `browserify src/index.js > public/bundle.js`
npm ERR! Exit status 1
```

And added a new warning:

```
npm WARN deprecated left-pad@1.3.0: use String.prototype.padStart()

> level@5.0.1 postinstall /home/jsclient/node_modules/level
> opencollective-postinstall || exit 0
