Hey @fwx5618177! 👋
Thanks for sharing.

General feedback on what gets included in the plugins list:

Some criteria to include packages in this list.

• Some documentation with at least some instructions on how to use the package.
• A CI job to run tests. (The tests are already there.)
• A prepack script and CI job to build the types. (The JSDoc types are already there.)
• The package should be published to npm.

It looks like documentation is there ✅ , CI is missing ⚠️, prepack script is missing ⚠️, and it isn't published to npm ⚠️ (https://www.npmjs.com/package/remark-codesandbox-sandpack)

More specific recommendations:

1. limit your dependencies to those downstream users directly need to run your package https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/356192fa74277749cebb9d1c3876e69c79df7ccf/package.json#L51-L68
   • dependencies that are for development only typescript, tsx, swc should not be included (instead devDependencies)
   • dependencies which might be used along side like react, react-markdown, remark should not be included in dependencies (instead devDependencies or peerDependencies)
2. When importing only types from a package use import type {} https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/356192fa74277749cebb9d1c3876e69c79df7ccf/src/index.ts#L2 to avoid side effects and clarify intent
3. Avoid self referential imports https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/356192fa74277749cebb9d1c3876e69c79df7ccf/src/index.ts#L3 will likely break build/bundle tools
4. The type configuration could be greatly simplified by setting "checkJs": true,, "module": "node16",, and "strict": true,. current: https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/356192fa74277749cebb9d1c3876e69c79df7ccf/tsconfig.json#L3-L41 example of simplified: https://github.com/remarkjs/remark-directive/blob/876a45ad4c021c74bb0b65383e838c8f3181e1eb/tsconfig.json#L1-L15
5. Packages should generally be shipped as raw JS or as close to it as possible, avoid pre-bundling/pre-polyfilling/pre-minifying code for users, let their build tools add the parts they need. https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/356192fa74277749cebb9d1c3876e69c79df7ccf/package.json#L23
6. Consider leveraging node:test (https://nodejs.org/api/test.html) or vitest (https://vitest.dev/) for running the test suite, they are fast, modern, and have solid support for ESM.
7. Do type check the test suite, this is how users will see the types, if the types are wrong and broken in the tests, they will be for users as well https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/356192fa74277749cebb9d1c3876e69c79df7ccf/tests/utils.spec.ts#L1

All done!

[ChristianMurphy]

At a high level, it looks like this plugin aims to work on HTML? If so it may make sense as a rehype plugin instead, where is can work more safely on the HTML AST.

Some specific comments.

1. It can be good to have an interface for properties, this both makes code easier to read, and allows you to export the type if wanted https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/src/htmlTemplate.ts#L1-L16

2. Avoid any type when possible, a more specific type for what a template or theme will help ensure correct usage https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/src/htmlTemplate.ts#L3-L4

3. Would it make sense to allow the react or sandpack sources and versions to be configurable? https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/src/htmlTemplate.ts#L26-L29

4. When there are type only imports it can be good to use import type { ... } to prevent side effects https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/src/runtimeEnv.ts#L2

5. Is it intentional that documentation switches between languages? https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/src/utils.ts#L50-L52

6. For module resolution that works in the most places you probably want to use Node16 https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/tsconfig.json#L5-L7

   A common misconception is that node16 and nodenext only emit ES modules. In reality, node16 and nodenext describe versions of Node.js that support ES modules, not just projects that use ES modules. Both ESM and CommonJS emit are supported, based on the detected module format of each file. Because node16 and nodenext are the only module options that reflect the complexities of Node.js’s dual module system, they are the only correct module options for all apps and libraries that are intended to run in Node.js v12 or later, whether they use ES modules or not.

   https://www.typescriptlang.org/docs/handbook/modules/reference.html#the-moduleresolution-compiler-option

7. Transitive dependencies probably should have valid typings, do you see an error if you enable lib check? https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/tsconfig.json#L19-L20

8. It is best to check the types in the tests, this ensures users can use the library with TypeScript https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/tests/utils.spec.ts#L1

9. In the GitHub action, consider using the official pnpm installer https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/.github/workflows/release.yml#L29, official installer https://github.com/pnpm/action-setup

10. It seems a bit surprising to manually generate a tarball, wouldn't npm or pnpm generate this? https://github.com/fwx5618177/remark-codesandbox-sandpack/blob/7eda3d772a7b73a32ce8303d6bf23be091659391/.github/workflows/release.yml#L45-L47

11. Commitlint can be very useful for checking commits and pr titles https://commitlint.js.org/
    https://commitlint.js.org/guides/ci-setup.html#github-actions
