fission-shell-web

Web shell for the Fission UI framework (WebAssembly target).

fission-shell-web is the current browser shell for running Fission applications via WebAssembly. It wraps the shared fission-shell-winit runtime on the wasm target and appends the generated canvas to the page automatically.

Status

What is ready today:

•

runnable WebApp wrapper backed by the shared winit runtime

•

checked-in examples/web-smoke/ browser example

•

first-party fission add-target web launcher output

•

Chromium live testing through fission test --target web and LiveTestClient

•

Fission-owned keyboard shortcuts, clipboard events, contextual actions, and IME composition

•

deny-by-default browser behavior with explicit BrowserDefaults opt-ins

What is still missing:

•

browser autocorrect/autofill and soft-keyboard replacement edge cases

•

Firefox and WebKit live-test drivers

Browser defaults

Fission suppresses browser behavior by default so application input is consistent with native targets. Delegate only the categories your application intentionally wants the browser to own:

WebApp::new(App)
    .with_browser_defaults(
        BrowserDefaults::CONTEXT_MENU | BrowserDefaults::WHEEL,
    )
    .run()

Categories not included in the allowlist remain Fission-owned. The default isBrowserDefaults::NONE.

WASM prerequisites

rustup target add wasm32-unknown-unknown
cargo install wasm-pack

Relevant paths:

•

crates/shell/fission-shell-web/

•

examples/web-smoke/

Do not treat fission-shell-desktop as the web entrypoint. The desktop shell carries desktop-specific runtime and test-driver dependencies that are not the right long-term WASM surface.

Verified commands

Build and serve the checked-in example:

rustup target add wasm32-unknown-unknown
cargo install wasm-pack
./examples/web-smoke/platforms/web/run-browser.sh

Build a generated app after fission add-target web:

./platforms/web/run-browser.sh

More setup detail lives in ../../../docs/platform-smoke-tests.md.
