Support Next.js

[jaywcjlove]

I created a nextjs package next-remove-imports to solve the problem.

Example: @uiwjs/next-remove-imports/example

npm i @uiw/[email protected]
npm i next-remove-imports

// next.config.js
const removeImports = require("next-remove-imports")();

module.exports = removeImports({
  // ✅  options...
});

import "@uiw/react-md-editor/markdown-editor.css";
import "@uiw/react-markdown-preview/markdown.css";
import dynamic from "next/dynamic";
import { useState } from "react";

const MDEditor = dynamic(
  () => import("@uiw/react-md-editor").then((mod) => mod.default),
  { ssr: false }
);
const EditerMarkdown = dynamic(
  () =>
    import("@uiw/react-md-editor").then((mod) => {
      return mod.default.Markdown;
    }),
  { ssr: false }
);

function HomePage() {
  const [value, setValue] = useState("**Hello world!!!**");
  return (
    <div data-color-mode="dark">
      <MDEditor value={value} onChange={setValue} />
      <div style={{ paddingTop: 50 }}>
          <EditerMarkdown source={value} />
      </div>
    </div>
  );
}

export default HomePage;

What worked for me (Next.js version 13.4.3) is inside your next.config.mjs add the following to your config:

experimental: {
    esmExternals: 'loose',
  },

@preetpatel that seems to only work sometimes. With that change, I am to get it to load, but every 5 minutes or so, it seems to crash again.

- error Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/code/node_modules/@uiw/react-markdown-preview/node_modules/react-markdown/index.js from /Users/zeus/code//node_modules/@uiw/react-markdown-preview/lib/index.js not supported.
Instead change the require of /Users/zeus/code/node_modules/@uiw/react-markdown-preview/node_modules/react-markdown/index.js in /Users/code/node_modules/@uiw/react-markdown-preview/lib/index.js to a dynamic import() which is available in all CommonJS modules.

Is simply adding

experimental: {
    esmExternals: 'loose',
  },

stable for you?

I tried

const removeImports = require("next-remove-imports")();

module.exports = removeImports({
});

But did not have any luck. Same problem. Perhaps I was not spreading it into module.exports correctly.

I get Error: Cannot find module 'babel-plugin-transform-remove-imports' when trying to use the next-remove-imports package
