func LoadFS ¶

func LoadFS(rootDir string) (fs.FS, error)

LoadFS creates a virtual filesystem that implements the Go module proxy protocol. It scans a directory of module source code and automatically generates all the necessary proxy files: /@v/list, /@v/{version}.mod, /@v/{version}.zip, and /@v/{version}.info.

The input directory structure should be: rootDir/

example.com/
  module1/
    @v/
      v1.0.0/
        go.mod
        main.go
        ...
      v1.1.0/
        go.mod
        main.go
        ...

The returned filesystem can be used with http.FileServer(http.FS(fsys)) to serve a module proxy over HTTP, or with os.CopyFS(dir, fsys) to write the proxy files to disk for use with file:// URLs.
