frus for VS Code

Run frus applications from VS Code, on any device.

• A device picker in the status bar: this computer, the connected phones and emulators, the browsers. It follows phones as they are plugged in and out.
• F5 builds the application for the selected device, starts it there and shows its log in the Debug Console: the desktop program's output, the phone's logcat, the browser's console. Errors are shown as errors.
• Reload on save: saving a Rust file builds the application again and brings it back on the same page, with the state of every component that keeps one (State::save). The ⚡ button in the debug toolbar, or Ctrl+F5, does the same; the toolbar's restart button starts it afresh.

No launch.json is needed: F5 in a frus application runs it on the selected device. To pin a device or pass arguments, add a configuration:

{
  "type": "frus",
  "request": "launch",
  "name": "frus on the phone",
  "cwd": "${workspaceFolder}",
  "deviceId": "android"
}

Requirements

The extension drives the frus command-line tool (frus daemon and frus run --machine). If it is not installed, the extension installs it with cargo install frus-cli; frus installs what it needs in turn (Rust targets, the Android SDK, wasm-bindgen).

Settings

Developing it

npm install
npm test        # the debug adapter, with a stand-in for frus
FRUS_E2E_FRUS=/path/to/frus FRUS_E2E_APP=/path/to/an/app npm test   # and with the real one
npm run package # frus-<version>.vsix
