I started trying to fix this in #2348, but it needs more work

I’m sorry you’re running into this. As @tadeuzagallo mentioned, this is a known issue, and we are working on it.

Here's a work around that I'm currently using:
https://stackblitz.com/edit/github-ttgbip?file=astro.config.mjs

Points to be aware of:

• I couldn't get process.env.NODE_ENV working inside astro.cong.mjs, so I added cross-env package and prefixed the scripts
• public folder assets must also be inside the subfolder

Hope it helps someone.

Closed out a few duplicate issues to use this as the primary since it's the oldest

Confirmed this still reproduces with the lastest beta - clone the subpath starter and run npm run build && npm run preview

Comparing against Vite's base behavior, it looks like the only fix needed is to include the base path in any assets at build time. dev and preview work as expected so hopefully this is an easy one to take care of 🤞

[tony-sull]

Expected behavior:

astro dev - base is ignored, all page URLs and asset paths are redirected internally

astro build - all assets are built to dist/assets, HTML src and hrefs all include the base, i.e. src="/blog/assets/img.asdf.jpg

astro preview - preview server respects the base path, all URLs are redirected from /subpath/... to /... internally (so assets are found in dist/assets)

Was poking around and noticed some work was happening on this front! Noting here as reference:

• Improvements to build and dev when building for subpaths #3156 (Merged)
• fix(markdown): file.url fixes #3198 (Merged)
• Allowing Vite to handle base config for deploying to subpaths #3178 (Draft)

In fact my minimal reproduction now loads assets correctly.

Looks like I missed closing this with the latest for subpaths, glad this is fixed now!
