DEPRECATED? memfs not compatible with this library.

[vipcxj]

I try to use memfs to replace this library, and found some problem

import { fs } from 'memfs'
compiler.outputFileSystem = fs // TS2741: Property 'join' is missing in type 'IFs' but required in type 'OutputFileSystem'.

Related to: webpack/webpack-dev-middleware#370 and #67.
