`app`


import { app } from "@tynd/core/client";

App identity and lifecycle. Callable from both frontend and backend.

`app.setInfo({ name, version })`

Sets the app’s identity. Typically called once from the backend at startup using fields from package.json:


import pkg from "../package.json";
await app.setInfo({ name: pkg.name, version: pkg.version });

Used by other APIs (notifications, tray tooltip, OS integration) to identify the app consistently.

Returns the registered name. Falls back to the binary file stem if setInfo wasn’t called.


const name = await app.getName();

Returns the registered version. Falls back to "0.0.0".


const version = await app.getVersion();

Spawns a fresh copy of the current binary and exits the current process. Equivalent to user-initiated relaunch.


await app.relaunch();

Useful after applying an update, toggling a runtime flag, or loading a new backend.

Exits the app gracefully. The app.onClose hook runs (with its usual 2-second watchdog) before the process terminates.


await app.exit(0);

Pass a non-zero code to signal an error to the invoking shell / installer. Default is 0.

app.exit(0) is preferable to process.exit(0) — the former runs lifecycle hooks, the latter doesn’t.
On Windows, relaunch uses cmd /c start so the current .exe unlocks before the new one runs.
On Linux, relaunch re-exec’s via /proc/self/exe.
On macOS, relaunch spawns via NSWorkspace.openApplication.
