@bluwy Correct me if I'm wrong but this seems more correct.

But that isn't how dev works?

Lines 715 to 727 in a7a20cf

	// html fallback
	if (config.appType === 'spa' || config.appType === 'mpa') {
	middlewares.use(htmlFallbackMiddleware(root, config.appType === 'spa'))
	}
	// run post config hooks
	// This is applied before the html middleware so that user middleware can
	// serve custom content instead of index.html.
	postHooks.forEach((fn) => fn && fn())
	if (config.appType === 'spa' || config.appType === 'mpa') {
	// transform index.html
	middlewares.use(indexHtmlMiddleware(root, server))

I've just checked and indexHtmlMiddleware() is a no-op if the .html file doesn't exist on the filesystem, so unless I'm missing something this seems to be a safe change. I've just udpated the PR to align dev.

I don't understand why we need to change this though. It was working fine before. Post-middlewares could intercept HTML pages and do something with it, but now they can't and I don't see much reason to explain the change.

Makes sense 👍
