TypeError: dts is not a function

[agiveygives]

Checklist

• I can reproduce this issue when running this plugin on its own.
  Other plugins, such as node-resolve are known to cause issues.
• I am running this plugin on .d.ts files generated by TypeScript.
  The plugin can consume .ts and even .js files (with allowJs: true), but this is known to cause issues.
• This issue is not related to rolling up @types.
  The plugin ignores these by default, unless respectExternal is set. @types can contain hand-crafted code which is known to cause issues.

Notes

• I'm following https://plainenglish.io/blog/react-component-library-with-ts-and-rollup-77aca0c727bf#rollupconfigjs
• https://stackoverflow.com/a/74304876 fixes the issue, but I thought I would log the issue since the README suggests the approach in the blog post I was following.

Error Message

[!] TypeError: dts is not a function

[aviemet]

Some issue. dts is not a function. Console logging shows that dts is an object with a key called default whose value is a function, but calling dts.default() also doesn't work.

[ZhengRui]

having the same issue, anyone found a solution?

[Swatinem]

dts is an object with a key called default whose value is a function

Together with the warning that was in the stackoverflow post you linked:

Node tried to load your configuration file as CommonJS even though it is likely an ES module.

Its most likely some cjs interop problem?

[sidonaldson]

This seems to work plugins: [dts.default()]

[Coin0804]

Same. But it finally works.However, I tried many ways and don't which step makes it work. Maybe you can rename your rollup.config.js to rollup.config.mjs?

[SokuRitszZ]

It works using [dts.default()]

[revelt]

Slightly off-topic but the part const packageJson = require("./package.json"); is a huge red flag, even if it works, you're not supposed to use require in the ESM program!

Correct way is according to Node.js Design Patterns 3rd. ED p.62:

import { createRequire } from "module";
const require = createRequire(import.meta.url);
const packageJson = require("./package.json");

Be careful when copy-pasting snippets blindly from dubious sites!

It is working with dts.default() ,
