Summary by CodeRabbit

  • New Features
    • The main window opens centered on screen.
    • Static assets can be delivered in compressed formats, and supported downloads can request specific byte ranges.
  • Bug Fixes
    • Scrolling now feels smoother, including on touch devices. Dialogs and listboxes retain their standard scrolling behavior.
    • Smooth scrolling respects system reduced-motion preferences.

📝 Walkthrough

Walkthrough

The PR adds a Tauri asset URI handler with path checks, range and compressed-file responses, and caching. It also changes desktop window and file-open handling, adjusts release build settings, and updates editor scrolling styles.

Changes

Asset URI protocol

Layer / File(s) Summary
Asset validation and response helpers
frontend/editor/src-tauri/src/lib.rs
New helpers validate paths against permitted directories, parse byte ranges, build file responses, and serve range requests and compressed sidecars.
Asset protocol registration and caching
frontend/editor/src-tauri/Cargo.toml, frontend/editor/src-tauri/src/lib.rs
The Tauri builder registers the asset URI handler. The handler routes range requests, tries Brotli and gzip sidecars, and caches selected asset types in an LRU limited to 128 entries and 64 MiB.

Desktop runtime handling

Layer / File(s) Summary
Window, exit, file-open, and release settings
frontend/editor/src-tauri/src/commands/window.rs, frontend/editor/src-tauri/src/lib.rs, frontend/editor/src-tauri/Cargo.toml
The main window is centered. Exit handling no longer calls cleanup_before_exit(). macOS file-open handling accepts only file-scheme URLs and converts them with to_file_path(). Release builds use optimization level 3, thin LTO, one codegen unit, and stripping.

Editor scrolling styles

Layer / File(s) Summary
Global scrolling behavior
frontend/editor/src/core/styles/index.css
The global stylesheet enables smooth scrolling on html and body, applies touch momentum scrolling, and sets scrolling to auto for dialogs, listboxes, and reduced-motion preferences.

Merge Risk: 🔵 Low · up to a235a

The desktop asset cache can stop retaining files after many distinct assets are requested. Fix its byte accounting before relying on the cache; the remaining risk is low.

Inline comments:
In `@frontend/editor/src-tauri/Cargo.toml`:
- Line 74: Remove the panic = "abort" setting from the release profile in
Cargo.toml so recoverable panics do not terminate the entire Tauri process;
leave the other release-profile settings unchanged.

In `@frontend/editor/src-tauri/src/lib.rs`:
- Around line 362-375: Update the asset cache in the handler around
`canonical_path` to store each entry’s file length and modification time
alongside its bytes, and compare that stamp with fresh metadata before serving a
cached entry; use an access that updates recency. Also bound cache capacity by
total bytes rather than entry count, while preserving the existing asset
response flow.

In `@frontend/editor/src/core/styles/index.css`:
- Line 8: Add a prefers-reduced-motion media override for the html and body
selectors in the global styles, setting scroll behavior to non-animated when
reduced motion is requested while preserving smooth scrolling otherwise.
- Line 12: Scope the universal `-webkit-overflow-scrolling: touch` declaration
in the styles rule to intended scroll containers so it does not create a
stacking context on `DrawingCanvas`’s modal content and obscure the pen-size
`Combobox` dropdown.

Since may be use cases where this is not desirable, it will be a simple boolean option.

I have an idea of how I&`#39`;m going to get around it, but it requires significantly more Rust code than I was hoping I would need to write.

Do not use process-wide abort for recoverable panics.

panic = "abort" makes a panic in any Tauri thread or async task terminate the entire process. Runtime unwrap and expect sites remain in the asset-response helpers, backend startup, and application setup. One unexpected panic can close all windows and discard unsaved work. RunEvent::ExitRequested is the only caller of cleanup_backend(), so abort does not execute that Rust cleanup path.

The bundled backend has a separate parent-process monitor. It can shut down the Java process after it detects that the Tauri process is gone, so the backend is not necessarily orphaned. The asset-handler closure also does not contain several direct .unwrap() calls; keep the concern focused on process-wide abort and the remaining runtime panic sites.

setting from the release profile in Cargo.toml so recoverable panics do not
terminate the entire Tauri process; leave the other release-profile settings

Scope -webkit-overflow-scrolling: touch to scroll containers.

The universal rule also affects the non-portal pen-size Combobox rendered inside DrawingCanvas's Modal. When that modal content scrolls, WebKit can create a stacking context and cause the dropdown to render below a sibling outside the modal. Apply this declaration only to intended scroll containers, or render the dropdown through a portal.

`-webkit-overflow-scrolling: touch` declaration in the styles rule to intended
scroll containers so it does not create a stacking context on `DrawingCanvas`’s
modal content and obscure the pen-size `Combobox` dropdown.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Track bytes for entries that LruCache::put evicts on capacity.

LruCache::put returns Some(old) only when it replaces the same key. When the cache is at its 128-entry limit, put evicts the least-recently-used entry and does not return it. self.bytes then keeps counting the evicted entry's size.

A code-split frontend can easily load more than 128 distinct js, css, woff2, wasm, and html assets, so self.bytes keeps drifting upward. When the drift passes ASSET_CACHE_MAX_BYTES, every put runs the while loop until the cache is empty, including the entry it just inserted. The counter is still above the limit after that. From then on the cache holds nothing and every request reads from disk. Memory stays bounded, but the cache stops working for the rest of the process.

LruCache::push returns the displaced pair in both cases: a same-key replacement and a capacity eviction.

Proposed fix
-        if let Some(previous) = self.entries.put(key, CachedAsset { bytes, len, modified }) {
-            self.bytes -= previous.bytes.len();
-        }
+        if let Some((_, displaced)) = self.entries.push(key, CachedAsset { bytes, len, modified }) {
+            self.bytes -= displaced.bytes.len();
+        }
         self.bytes += size;
