Does grunt-concat have analogues that support import (in a file)?

Question

Grunt.js

Please tell me a grunt plugin similar to grunt-concat, but it understands import directives in the collected files:
Something
@import 'foo/bar.md'
like this - should insert the contents of foo/bar.md in place of this line
It is clear that bar.md can also contain import directives.
My google-fu didn't help me. All found plug-ins do not do the right thing.
Thank you!

Answer 1

I wrote my task , it's not difficult.
We read the file , go through the regular expression, find the file names, replace, write the file where it should be.
The replacement will look something like this:

fileContent = fileContent.replace(/@import '(\S+)'/mg, function (match, filepath) {
    return grunt.file.read(filepath)
})
