const electronHmr = new ElectronHmr({
    electronBinaryPath: electron.toString(),

Three way to rebuild electron

1. you can use rebuild() to rebuild the electron

electronHmr.rebuild()

2. start hot module replace, it will watch file change and rebuild automaticly

electronHmr.watch(/*options*/)

3. or you can use chokidar to watch file and rebuild manually

import { watch } from 'chokidar';
watch('.').on('change', (path, stats) => {
    if (stats?.isFile /* or some condition*/) {
        // rebuild the electron
        electronHmr.rebuild()
    }
});
