The web transport implements LiveLink::publish and the hosting and sharing background requests over the page's WebSocket. Managing connections run as exchanges (exchange.rs) in the browser client's driver; the requests and what their answers mean are shared with the desktop transport (requests.rs). The Share popover offers online sharing in the browser (no local network), and Publish to server opens there. Fixes#917.
Where the browser lists them (window.queryLocalFonts, Chromium), the font menu offers Use fonts installed on this computer; the fonts join the font database by name and each style's bytes are read only when text uses it, then auto-sizing text refits. Rust only (js-sys/web-sys). Fixes#1051.
The browser build's wasm was 25,982,540 bytes, past the gate raised for 0.12.1. It is now
23,915,213 bytes (22.8 MiB), 1.2 MiB under the restored 24 MiB gate:
- Catalog rows keep their plural forms behind a reference: Text is two words, not room for
four strings, across ~52,000 baked-in rows (-454 KB).
- The browser build compiles with wasm SIMD (apps/figcraft-web/.cargo/config.toml, wasm-opt
--enable-simd), so egui's glyph rasterizer leaves out its scalar SIMD fallback (-1.6 MB).
The plugin workspace is built from the repository root and stays without SIMD.
- Revert the gate raise (cb227c97); the hosting guide names the WebAssembly SIMD requirement.
The 0.12.0 release's Web job failed at 25,319,327 bytes against the 24 MiB (25,165,824-byte) gate. opt-level z, fat LTO and wasm-opt -Oz are already in place and extra wasm-opt passes save only ~20 KB, so the gate moves to 25,690,112 bytes, still under Cloudflare's 25 MiB per-file cap. The wasm grew ~2 MB in three days (egui 0.37, new features); bringing it back down is follow-up work.

- Browser client (step 4): the web build joins sessions a desktop app hosts
through the browser's WebSocket API (web-sys, binary frames, the same
message encoding). Its connection logic is a target-independent state
machine (collab-net driver.rs): hello on open, changes and presence held
until the welcome, throttled presence, keep-alive pings, a silent host
counted as dropped, reconnect with backoff, final refusals. Tested natively
against a scripted socket and a real host over loopback. Hosting stays
desktop-only (LiveLink::can_host; collab.peers canHost). https pages are
told up front that they can only reach ws:// sessions on this computer.
- Shared join logic (join.rs: GuestConfig, outcomes, taking in host messages)
and transport limits (limits.rs) used by the native guest and the browser.
- Invite links: `figcraft figcraft://join?...` joins on start (a bad link
opens the Join dialog with it); file:// arguments are paths. Windows
registers a per-user figcraft:// opener (HKCU\Software\Classes\figcraft)
behind a Registry trait (tests use a fake): collab.registerLinks {on?} and a
Preferences checkbox, default on for installed builds, never for builds
from source. macOS Info.plist declares CFBundleURLTypes; the Linux desktop
entry declares x-scheme-handler/figcraft and passes %U.
- Join dialog: Escape closes it and no longer reaches the canvas (selection
kept); its field has the keyboard when it opens.
- Docs: collab-protocol (browser client, links, mixed content), mcp,
control-protocol, README, web hosting notes, collaboration wording in the
progress docs (numbers unchanged).
