How about assuming any relative link in a markdown file should be appended with a pathPrefix? Otherwise, we can wrongfully skip adding the pathPrefix to the links starting with something similar to a pathPrefix value. For example, having a pathPrefix = "/web" and a relative link /website/details we'll get a link with no pathPrefix added.

Yes. Mb its better to skip !node.url.startsWith(pathPrefix) condition.
@KyleAMathews what You think?

gatsby-link does not check if link startsWith(pathPrefix), so looks like this code also should not.

@bodia-uz yeah — don't see a reason to add that check. E.g. what if there was a path named /my-site/ but your prefix was also /my-site/. Then that path would mysteriously not be prefixed.
