@1995parham, thanks for submitting your issue.
Fiber is really flexible, you could create your own error handling
logic.
The status code defaults to 200
unless changed, you can remove that.
In Fiber v1.5.0
you can pass errors in the Next
method.
package main
import "github.com/gofiber/fiber"
func main() {
app := fiber.New()
app.Post("/api/register", func (c *fiber.Ctx) {
if err := c.JSON(&User); err != nil {
c.Next(err)
}
})
app.Get("/api/user", func (c *fiber.Ctx) {
if err := c.JSON(&User); err != nil {
c.Next(err)
}
})
app.Put("/api/update", func (c *fiber.Ctx) {
if err := c.JSON(&User); err != nil {
c.Next(err)
}
})
app.Use("/api", func(c *fiber.Ctx) {
c.Set("Content-Type", "application/json")
c.Status(500).Send(c.Error())
})
app.Listen(1337)
}
We are working on a better way to handle global errors.
Passing the err
into c.Next(err)
would be nice.
So you can retrieve the error from the Ctx later on with c.Error()
for example.
PS: We added Next(err)
& app.Recover(handler)
& c.Error()

@1995parham thx for issue.
We're working around easy way to error handling right now on Fiber. Stay tuned! 😉
from fiber.
@koddr Thanks for your response 🙌 I will wait.
from fiber.
@Fenny I agree with your solution, we can return an error from the handler. If you want, I can create a PR for it.
from fiber.
I will create PR so we can work on it 🙌
from fiber.
@1995parham, me and @koddr are actually discussing some kind of recover
feature.
This has nothing to do with the c.Next(err)
, but we would like to hear your thoughts on this.
package main
import (
"./fiber"
)
func main() {
app := fiber.New()
app.Get("/", func(c *fiber.Ctx) {
panic("I panic")
})
// app.Panic, app.Error // not sure yet
app.Recover(func(c *fiber.Ctx) {
fmt.Println(c.Error()) // => "I panic"
c.SendStatus(500) // => 500 "Internal Server Error"
})
app.Listen(3000)
}
from fiber.
@Fenny I think to recover from panic in handlers is an excellent feature, and it would be useful in long-running applications. The proposed syntax is simple and useful.
from fiber.
@Fenny, sorry for bothering you again. I have checked the new API, and it was good. But is there any way to return an error from the handler, and it automatically passed to the Next
method? Like handlers of echo.
