Deprecate sanitize and sanitizer options #1504

Is sanitizer option deprecated?
#1504 affect only sanitize option?
Its my error. sanitizer option work with sanitize option.

Also, I think that release note or documentation should includes migration guide from sanitize to sanitize library. The release note and documentation have an lack of concrete example code.

[UziTech]

@azu the documentation for the sanitize option lists a few other libraries that do a much better job sanitizing html.

[azu]

@UziTech Yes, I know.

I've tried to use marked@0.7 and DOMPurify, but this combination has a bit complex context.
Because, DOMPurify does not work on Node.js without jsdom.

• marked is universal/isomophic library
• DOMPurify is not universal/isomophic library
  • It require jsdom for Node.js

The browser enviroment does not need jsdom, but Node.js env does need jsdom.
It require a bit complex code.

if(THIS_ENV_IS_NODE){returnmarked+dompurify+jsdom}else{returnmarked+dompurify}

So, I've created a wrapper library for optimizing Browser and Node.js.

• https://github.com/azu/safe-marked

safe-marked is a wrapper library of marked, DOMPurify, and jsdom.
Also, safe-marked define 'browser' field in package.json for optimizing browser bundle.
The browser entry point does not include jsdom.

This wrapper aim to reduce pacakge size for browser.

Conclusion

The documentation just say following

Marked does not sanitize the output HTML. Please use a sanitize library, like DOMPurify (recommended), sanitize-html or insane on the output HTML! 🚨

Afte using marked + DOMPurify, I feed that it is hard to use marked safety.
I think that we need to improve documentation about the usage of sanitizing.
Or just come back to support sanitize option...

However, The documentation is not fundamental solution.

Thanks.

📝 Note: The size of recommentation libraries :

sanitize-html is too large. insane looks like that is not maintained and have some problem.
So, I've selected DOMPurify. DOMPurify is maintained by security company.
