export function main() {
return platformBrowserDynamic().bootstrapModule(MainModule);
}
// boot on document ready
bootloader(main);
bootloader
is only needed to detect that the dom is ready before bootstraping otherwise bootstrap. This is needed because that dom is already ready during reloading.
In production you only need bootloader which just does this:
export function bootloader(main) {
if (document.readyState === 'complete') {
main()
} else {
document.addEventListener('DOMContentLoaded', main);
}
}
You would bootstrap your app the normal way, in production, after dom is ready. Also, in production, you should remove the loader:
{
test: /\.ts$/,
loaders: [
'awesome-typescript-loader',
].concat(prod ? [] : '@angularclass/hmr-loader')
},
