Request Timeouts

The timeout middleware changes the request context; downstream database, HTTP, and application calls must use c.Context() for cancellation to propagate.

package main


import (
  "log"
  "time"


  "github.com/0mjs/zinc"
  "github.com/0mjs/zinc/middleware"
)


func main() {
  app := zinc.New()
  app.Use(middleware.ContextTimeoutWithConfig(middleware.ContextTimeoutConfig{
    Timeout: 3 * time.Second,
    Skipper: func(c *zinc.Context) bool {
      return c.Path() == "/events"
    },
  }))


  app.Get("/report", func(c *zinc.Context) error {
    select {
    case <-time.After(2 * time.Second):
      return c.JSON(zinc.Map{"status": "ready"})
    case <-c.Context().Done():
      return c.Context().Err()
    }
  })


  log.Fatal(app.Listen(":8080"))
}

Reduce the middleware timeout below two seconds to see Zinc return the default 503 Service Unavailable timeout error.
