[fix]WWW: Vite SSR remote import error by using JSR package

[SisyphusZheng]

Problem

Vite SSR in Node.js throws the following error:

[ERR_UNSUPPORTED_ESM_URL_SCHEME] Only file and data URLs are supported by the default ESM loader. Received protocol 'https'

This is caused by attempting to import modules via a remote https:// URL, which is supported by Deno but not by Node.js/Vite.

Solution

Added the JSR package for @fresh/plugin-vite using:

deno add jsr:@fresh/plugin-vite

Updated deno.json imports:

"imports": {
  "@fresh/plugin-vite": "jsr:@fresh/plugin-vite@^0.9.13",
  "@tailwindcss/vite": "npm:@tailwindcss/vite@^4.1.12",
  "vite": "npm:vite@^7.1.4",
  "vite-plugin-inspect": "npm:vite-plugin-inspect@^11.3.2"
}

Result

• The SSR error is resolved.
• The project now works correctly with Vite SSR in Node.js environments.

I don't understand how the proposed changes get rid of the mentioned error message.

Previously, when I directly forked the project, I couldn't successfully run the dev command in www. An error occurred, and I was required to add a specific file. However, I forgot to take a screenshot of the issue, and now it seems impossible to reproduce it. If I don't encounter this problem again within three days, I will close this
