TypeError on config run (ESM Support)

I have my Vite config set up like so:

import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";
import checker from "vite-plugin-checker";

export default defineConfig({
	plugins: [
		vue(),
		checker({
			typescript: true,
			vueTsc: true,
		}),
	],
});

I’m using this in a Vue 3 project, and my aim is to set up proper type checks separate from VSCode’s since Vite does not intend to support this, even at build time.

After adding the vite-plugin-checker import and calling checker, running vite or vue-tsc results in an error:

failed to load config from /[...]/vite.config.js
error when starting dev server:
TypeError: checker is not a function

As far as I can tell, I’ve imported vite-plugin-checker correctly according to the README documentation. Either I’m missing some obvious thing here, or the export structure is not the same at runtime as its declared type.

I just had the issue, it was because i had configured "type": "module" in your package.json that forces vite to use esm however vite-plugin-checker is still published as CJS

fixed in 0.4.5
