Description
Reproduction link or steps
What is expected?
No warnings and correct file path.
What is actually happening?
[EMPTY_IMPORT_META] Warning: `import.meta` is not available with the `cjs` output format and will be empty.
╭─[ x.ww:1:1 ]
│
1 │ import.meta.__ROLLDOWN_ASSET_FILENAME
│ ─────┬─────
│ ╰─────── You need to set the output format to `esm` for `import.meta` to work correctly.
───╯
And part of the output is:
var require_x = /* @__PURE__ */ __commonJS({ "x.ww": ((exports, module) => {
module.exports = {}.__ROLLDOWN_ASSET_FILENAME;
}) });System Info
