API handler wrapper

Usage

api.Wrap(handler)

Function Wrap wraps API handler and returns standard http.HandlerFunc. It encapsulate body parsing.

Example

package main

import (
    "context"
    "fmt"
    "log"
    "net/http"

    "github.com/neonxp/api"
)

func main() {
    h := &http.Server{Addr: "0.0.0.0:3000"}
    mux := http.NewServeMux()
    h.Handler = mux

    // Here is magic!
    mux.Handle("/hello", api.Wrap(handleHello))

    if err := h.ListenAndServe(); err != http.ErrServerClosed {
        log.Fatalln(err)
    }
}

// Our API handler with custom request and response types
func handleHello(ctx context.Context, req *helloRequest) (*helloResponse, error) {
    return &helloResponse{Message: fmt.Sprintf("Hello, %s!", req.Name)}, nil
}

// Custom request type
type helloRequest struct {
    Name string `json:"name"`
}

// Custom response type
type helloResponse struct {
    Message string `json:"message"`
}
