@opentray/tsdown-plugin

tsdown adapter for the OpenTray runtime artifact packaging contract.

import { defineConfig } from "tsdown";
import { openTrayTsdownPlugin } from "@opentray/tsdown-plugin";

export default defineConfig({
  entry: ["src/main.ts"],
  plugins: [
    openTrayTsdownPlugin({
      app: { id: "com.example.build", name: "Build" },
      runtimeHost: { source: "target/release/build-tray-host" },
      nativeArtifacts: {
        "darwin-arm64": { source: "target/release/libbuild_tray.dylib" },
      },
    }),
  ],
});

The adapter stages artifacts during the tsdown build output (writeBundle) and writes the same manifest shape as @opentray/packaging. It does not own tray lifecycle, sessions, backend selection, or extension dispatch.

outDir is resolved from the writeBundle output options (options.dir). mode defaults to production. Pass outDir or mode in the plugin options to override them when running outside a real tsdown build.
