BUG Deskulpt can't handle syntax error in widget js code

[Xinyu-Li-123]

When there is a syntax error in the widget js code, Deskulpt will crash. This happens at commit 442cf1, the head commit when I submit this issue. Below is a minimal example to reproduce this bug.

const React = window.__DESKULPT__.defaultDeps.React;

// Syntax error here, misspell "const" as "conts", will crash Deskulpt
conts bannerText = "My Simple Banner";

function Banner() {
  return (
    <div>
      <h1>{bannerText}</h1>
    </div>
  );
}

export default {
  render: () => <Banner />,
};

And is the error message produced when Deskulpt crashes. It happens when I add this widget to the widgets folder and render. I run Deskulpt with npm run tauri dev.

error: Expected ';', '}' or <eof>

@Charlie-XIAO @ROMEEZHOU You might want to check this out since we are writing tests for bundler this week

The error is currently emitted into the console, seems I forgot to change that. I need to figure out how to emit as a string though.
