TSGPUI v0.3.0

TSGPUI v0.3.0

• Run host calls on worker threads and queue backend tasks, so the UI stays responsive.
• Add native file access for the backend, with a notes example that uses it.
• Add a token-checked browser preview endpoint for api.native.
• Add build diagnostics, persisted state, data-fetch POST, and viewport units.
• Split the GPUI view into focused modules.
• Refresh the README, the native API docs, and the website, which now renders the architecture, syntax, and safety docs in place.

Known limitations

• macOS bundles are unsigned and not notarized. Gatekeeper may require approval before first launch.
• Table and semantic tags use basic native container layout; browser table layout and disclosure behavior are not implemented.
• System tray support and multiple independent windows/apps are not included in this release.

See the repository documentation for renderer and platform limitations.

TSGPUI v0.3.0-beta.1 (pre-release)

Pre-release for testing. It is not for production use, and it may have bugs and breaking changes before 0.3.0.

Full change list: v0.2.0...v0.3.0-beta.1

Highlights

• Native host API (api.native): file access confined to granted folders, process spawn from an allowlist (no shell), window control, desktop notifications, and local IPC between the app and other processes.
• Host work runs in the background: calls run on worker threads so the window stays responsive. Backend tasks queue behind a waiting action and roll back cleanly if they fail.
• Browser preview runs api.native through tsgpui preview, using a token-checked local endpoint.
• examples/notes: a small app that saves, opens, deletes and lists notes through the native file API.
• Development workflow: persisted state ("persist": true), a development overlay (F12 or Ctrl+Shift+I), and build diagnostics that keep the last good build running.
• CSS and HTML: viewport units, z-index, and data-fetch POST with state-bound bodies.
• Website and docs: new landing page, documentation section, and refreshed README.

Known gaps

• The native window has not been run on macOS or Linux. CI builds the host on Windows and macOS only.
• The WebView renderer does not provide api.native yet.
• process.spawn waits for the child to exit, so long-running services need a separate process.start API.
• Window minimize, maximize and restore work only in the native host, not in the browser preview.
• IPC peers disconnect when the app reloads.
• The landing page's status section is out of date.

Try the notes example

bun install
bun run gpui:host
node packages/cli/bin/tsgpui.mjs build --project examples/notes

TSGPUI v0.2.0

TSGPUI v0.2.0

• Add native macOS .app packaging and CI builds for Intel and Apple Silicon.
• Extend native HTML coverage with semantic and table tags.
• Add per-edge solid border widths and styles.
• Fix the workspace package name and refresh Bun/Cargo lockfiles.

Known limitations

• macOS bundles are unsigned and not notarized. Gatekeeper may require approval before first launch.
• Table and semantic tags use basic native container layout; browser table layout and disclosure behavior are not implemented.
• System tray support and multiple independent windows/apps are not included in this release.

TSGPUI v0.1.0

First public release of TSGPUI, an experimental, source-first prototype that compiles a supported subset of HTML and CSS into native GPUI elements and runs TypeScript backend actions in embedded QuickJS. No Chromium, no WebView.

Highlights

• Native controls: buttons, text inputs, textareas, checkboxes, selects, and form submission with required and numeric validation
• Live state via data-bind and {{interpolation}}, with data-repeat for lists
• Keyboard shortcuts (data-shortcut), native confirm dialogs (data-confirm), and clipboard copy/paste
• Native file open/read/save dialogs (1 MiB limit)
• User-initiated HTTPS GETs (data-fetch) restricted to hosts listed in permissions.network
• @media queries with min/max width and height in px
• Reusable static components, embedded PNG/JPEG/GIF/WebP/BMP/SVG images
• CLI packaging into a single executable, with tsgpui dev for fast reload
• Landing page in website/

Testing

• 15/15 JS compiler and CLI tests pass
• Typecheck and example compilation pass
• Native host builds with cargo check and cargo test (the Rust test suite currently has no tests)

Known limitations

• The native Windows host has not been run end-to-end; GUI behavior is not yet verified
• HTML/CSS is a documented subset; no position, animations, rich text, or accessibility tree yet
• The packaged-executable overlay is not signed or tamper-proof, and has not been tested against real PE loaders
