Support for inapp links

[daniil00d]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)

Problem

When inputting a link formatted as [hello]({any_app}://something) or <{any_app}://something>, a link node with an empty href is created.

Solution

I'd like the library to support this case: we input a link to an application (installed on the current device), and upon clicking said link, the application is opened. An example being: click me

Alternatives

One potential solution could be to give the user more control over the transformation of links obtained from the text. This could be achieved, for example, by extending the transformLinkUri prop, where it would be possible to access the protocol, domain, pathname, query, etc.

Welcome @daniil00d! 👋

They are supported, but disabled by default as they are insecure.
You can set your own URL transform in the options https://github.com/remarkjs/react-markdown#options
See #774 for some examples

Hi! Thanks for taking the time to contribute!

Because we treat issues as our backlog, we close duplicates to focus our work and not have to touch the same chunk of code for the same reason multiple times. This is also why we may mark something as duplicate that isn’t an exact duplicate but is closely related.

Thanks,
