Graceful Shutdown

package main

import (
    "context"
    "errors"
    "log"
    "net/http"
    "os"
    "os/signal"
    "syscall"
    "time"

    "github.com/0mjs/zinc"
)

func main() {
    app := zinc.New()
    app.Get("/health", func(c *zinc.Context) error {
        return c.String("ok")
    })

    go func() {
        if err := app.Listen(":8080"); err != nil && !errors.Is(err, http.ErrServerClosed) {
            log.Printf("server: %v", err)
        }
    }()

    signals, stop := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM)
    defer stop()
    <-signals.Done()

    ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
    defer cancel()
    if err := app.Shutdown(ctx); err != nil {
        log.Fatal(err)
    }
}

Readiness checks should fail before shutdown begins so a load balancer stops sending new traffic.
