The PrefixDir function
The
iris.PrefixDir function wraps an existing "fs" file system and returns a new one which open files by prepending the path with the given "prefix".func PrefixDir(prefix string, fs http.FileSystem) http.FileSystem
It is extremely useful when you use a
go-bindata file to embed both view templates and public static files. With PrefixDir you can select which directory to use to serve static files and which to render views.│ main.go
| bindata.go
└───data/
└──────views/
│ ...your templates
└──────public/
│ ...your public assets
Let's build the
bindata.go file which will contain the embedded ./data directory:$ go get -u github.com/go-bindata/go-bindata/...
$ go-bindata -fs ./data/...
Use the
./data/views for templates and ./data/public for file server:templatesFS := iris.PrefixDir("./data/views", AssetFile())
app.RegisterView(iris.HTML(templatesFS, ".html"))
publicFS := iris.PrefixDir("./data/public", AssetFile())
app.HandleDir("/", publicFS)
