Simple, powerful, high-performance modern npm package development solution.

// taking from https://github.com/egoist/tsup/blob/dev/assets/cjs_shims.js

// Shim globals in cjs bundle
// There's a weird bug that esbuild will always inject importMetaUrl
// if we export it as `const importMetaUrl = ... __filename ...`
// But using a function will not cause this issue

const getImportMetaUrl = () =>
  typeof document === 'undefined'
    ? new URL(`file:${__filename}`).href
    : document.currentScript?.src || new URL('main.js', document.baseURI).href;

// define importMetaUrl
export const importMetaUrl = /* @__PURE__ */ getImportMetaUrl();
