Summary by Sourcery

Enable pre-compressed gzip asset delivery in the frontend build and nginx configuration.

New Features:

• Add Vite compression plugin to generate gzip-compressed frontend assets during build.

Enhancements:

• Configure nginx to always serve pre-compressed .gz files via gzip_static and simplify asset location handling.

Build:

• Add vite-plugin-compression dependency and integrate it into the Vite config to gzip selected asset types.

Deployment:

• Update nginx configuration to serve pre-compressed static assets from the frontend build output.

Reviewer's Guide

Adds gzip pre-compression of selected frontend build assets via Vite and configures nginx to always serve these .gz files from /assets, removing the need for try_files and the original uncompressed assets.

File-Level Changes

Change	Details	Files
Enable gzip pre-compression of frontend build assets during Vite build.	Import vite-plugin-compression into the Vite config. Register viteCompression in the plugins array with gzip algorithm, .gz extension, 1KB threshold, and deletion of original files. Restrict compression to specific asset types including JS, CSS, JSON, SVG, text, XML, WASM, and GLB files.	core/frontend/vite.config.js
Configure nginx to serve pre-compressed .gz assets and simplify /assets/ location handling.	Enable gzip_static always at the http level so nginx serves .gz files even if originals are missing, when the client supports gzip. Simplify the /assets/ location by removing try_files, relying on nginx static file resolution under the configured root. Keep caching headers for /assets/ unchanged while serving pre-compressed content.	core/tools/nginx/nginx.conf
Declare vite-plugin-compression as a frontend dependency.	Add vite-plugin-compression to devDependencies in the frontend package.json with version ^0.5.1.	core/frontend/package.json

Hey - I've left some high level feedback:

• Using deleteOriginFile: true means only .gz assets will be deployed; consider whether any non-gzip-capable clients, tooling, or direct file access (e.g. via S3/bucket browsing or other servers) rely on the original files and whether it’s safer to keep them.
• Removing try_files $uri $uri/; from the /assets/ location changes how missing or directory requests are handled; confirm that you don’t rely on any fallback behavior there (e.g. serving a default file or index) and that 404 handling remains as intended.

- Using `deleteOriginFile: true` means only `.gz` assets will be deployed; consider whether any non-gzip-capable clients, tooling, or direct file access (e.g. via S3/bucket browsing or other servers) rely on the original files and whether it’s safer to keep them.

Hey - I've left some high level feedback:

• Using viteCompression with deleteOriginFile: true means the build output only contains .gz versions of the filtered assets; consider keeping originals (or limiting this to assets you know are only fetched via nginx with Accept-Encoding: gzip) to avoid breaking any non-gzip consumers or tooling that expects raw files.
• Enabling gzip_static always; in nginx will serve .gz files even when the client does not send Accept-Encoding: gzip; consider using gzip_static on; instead (or a more targeted location block) to avoid corrupt responses for clients or intermediaries that cannot handle gzip-encoded content.
