vite-plugin-legacy-worker-repro

Repro

• Run pnpm install to install dependencies
• Run pnpm build && pnpm preview
• Observe the runtime error when previewing the app in the browser:

  ReferenceError: Can't find variable: __VITE_IS_LEGACY__
  

Alternately:

• Run pnpm install to install dependencies
• Run pnpm build
• Observe that the worker output file (e.g. dist/assets/worker-NmsWRLpo.js) contains a reference to __VITE_IS_LEGACY__:

  (function() {
      "use strict";
      console.log("[worker] import.meta.env", {
          BASE_URL: "/",
          MODE: "production",
          DEV: !1,
          PROD: !0,
          SSR: !1,
          LEGACY: __VITE_IS_LEGACY__
      })
  })();
