How to use codeHike with esm import in next.js

See original GitHub issue

The next.js config is cjs file. But some remark plugins only provide esm packages, so i change my next.config.js to next.config.mjs and use it like:

import remarkGfm from 'remark-gfm';
import rehypeSlug from 'rehype-slug';

const composedConfig = composePlugins([
  mdx({
    extension: /\.mdx?$/,
    options: {
      remarkPlugins: [
        remarkFrontmatter,
        // [remarkToc, { maxDepth: 2 }],
        remarkGfm,
      ],
      rehypePlugins: [rehypePrism, rehypeSlug],
      providerImportSource: '@mdx-js/react',
    },
  }),
  /** @type {import('next').NextConfig} */
  {
    reactStrictMode: true,
    // experimental: {
    //    reactMode: 'concurrent',
    // },
    experimental: {
      outputStandalone: true,
    },
    pageExtensions: ['ts', 'tsx', 'js', 'jsx', 'md', 'mdx'],
  },
]);

I need use codeHike with remark plugins together, i tried:

import remarkGfm from 'remark-gfm';
import rehypeSlug from 'rehype-slug';
import codeHike from '@code-hike/mdx';
const { remarkCodeHike } = codeHike;

const composedConfig = composePlugins([
  mdx({
    extension: /\.mdx?$/,
    options: {
      remarkPlugins: [
        remarkFrontmatter,
        // [remarkToc, { maxDepth: 2 }],
        [remarkCodeHike],
        remarkGfm,
      ],
      rehypePlugins: [rehypePrism, rehypeSlug],
      providerImportSource: '@mdx-js/react',
    },
  }),
  /** @type {import('next').NextConfig} */
  {
    reactStrictMode: true,
    // experimental: {
    //    reactMode: 'concurrent',
    // },
    experimental: {
      outputStandalone: true,
    },
    pageExtensions: ['ts', 'tsx', 'js', 'jsx', 'md', 'mdx'],
  },
]);

Well, import is OK, but i got erros:

error - Failed to load next.config.mjs, see more info here https://nextjs.org/docs/messages/next-config-error
C:\Users\someone\Git\someproject\node_modules\@code-hike\mdx\dist\index.esm.js:1
import { FontStyle, setCDN, getHighlighter } from 'shiki';
^^^^^^

SyntaxError: Cannot use import statement outside a module
