**impart** is a library for the final layer between the API and the consumer. It's used in the latest [Write.as](https://write.as) and [HTMLhouse](https://html.house) APIs.
We're still in the early stages of development, so there may be breaking changes.
## Example use
```go
package main
import (
"fmt"
"github.com/writeas/impart"
"net/http"
)
type handlerFunc func(w http.ResponseWriter, r *http.Request) error
func main() {
http.HandleFunc("/", handle(index))
http.ListenAndServe("127.0.0.1:8080", nil)
}
func index(w http.ResponseWriter, r *http.Request) error {
fmt.Fprintf(w, "Hello world!")
return nil
}
func handle(f handlerFunc) http.HandlerFunc {
return func(w http.ResponseWriter, r *http.Request) {
handleError(w, r, func() error {
// Do authentication...
// Handle the request
err := f(w, r)
// Log the request and result...
return err
}())
}
}
func handleError(w http.ResponseWriter, r *http.Request, err error) {
if err == nil {
return
}
if err, ok := err.(impart.HTTPError); ok {
impart.WriteError(w, err)
return
}
impart.WriteError(w, impart.HTTPError{http.StatusInternalServerError, "Internal server error :("})
