Go REST

Some handy functions for developing JSON-based REST APIs. In particular, it simplifies reading HTTP request bodies, writing HTTP response bodies, and handling errors.

Error handling

You can use errors.Is() to ascertain the type of errors thrown by validation functions, but for the most part, this isn't necessary because the write functions already do that.

Example

package main

import (
	"errors"
	"math/rand"
	"net/http"

	"github.com/annybs/go/rest"
)

type Handler struct{}

func (*Handler) ServeHTTP(w http.ResponseWriter, req *http.Request) {
	n := rand.Intn(3)
	if n == 0 {
		rest.WriteResponseJSON(w, http.StatusOK, map[string]string{"status": "OK"})
	} else if n == 1 {
		rest.WriteErrorJSON(w, errors.New("the original error message is added to data.error"))
	} else {
		rest.WriteErrorJSON(w, rest.ErrNotFound)
	}
}

func main() {
	http.ListenAndServe("localhost:8000", &Handler{})
}

Open http://localhost:8000 in your browser and refresh a bunch of times to see the different possible responses.
