# Official Sentry fiber Handler for Sentry-go SDK
**Godoc:** https://godoc.org/github.com/getsentry/sentry-go/fiber
**Example:** https://github.com/getsentry/sentry-go/tree/master/example/fiber
## Installation
```sh
go get github.com/getsentry/sentry-go/fiber
```
```go
import (
"fmt"
"github.com/gofiber/fiber/v2"
"github.com/getsentry/sentry-go"
sentryfiber "github.com/getsentry/sentry-go/fiber"
"github.com/gofiber/fiber/v2/utils"
)
```
To initialize Sentry's handler, you need to initialize Sentry itself beforehand
```go
if err := sentry.Init(sentry.ClientOptions{
Dsn: "your-public-dsn",
}); err != nil {
fmt.Printf("Sentry initialization failed: %v\n", err)
}
// Create an instance of sentryfiber
sentryHandler := sentryfiber.New(sentryfiber.Options{})
// Once it's done, you can attach the handler as one of your middlewares
app := fiber.New()
app.Use(sentryHandler)
// And run it
app.Listen(":3000")
```
## Configuration
`sentryfiber` accepts a struct of `Options` that allows you to configure how the handler will behave.
Currently it respects 3 options:
```go
// Repanic configures whether Sentry should repanic after recovery, in most cases it should be set to false,
// as fasthttp doesn't include it's own Recovery handler.
Repanic bool
// WaitForDelivery configures whether you want to block the request before moving forward with the response.
// Because fasthttp doesn't include it's own `Recovery` handler, it will restart the application,
// and event won't be delivered otherwise.
WaitForDelivery bool
// Timeout for the event delivery requests.
Timeout time.Duration
```
## Usage
`sentryfiber` attaches an instance of `*sentry.Hub` (https://godoc.org/github.com/getsentry/sentry-go#Hub) to the request's context, which makes it available throughout the rest of the request's lifetime.
You can access it by using the `sentryfiber.GetHubFromContext()` method on the context itself in any of your proceeding middleware and routes.
And it should be used instead of the global `sentry.CaptureMessage`, `sentry.CaptureException`, or any other calls, as it keeps the separation of data between the requests.
**Keep in mind that `*sentry.Hub` won't be available in middleware attached before to `sentryfiber`!**
```go
// Later in the code
sentryHandler := sentryfiber.New(sentryfiber.Options{
Repanic: true,
WaitForDelivery: true,
})
enhanceSentryEvent := func(ctx *fiber.Ctx) {
if hub := sentryfiber.GetHubFromContext(ctx); hub != nil {
hub.Scope().SetTag("someRandomTag", "maybeYouNeedIt")
}
ctx.Next()
}
app := fiber.New()
app.Use(sentryHandler)
app.All("/foo", enhanceSentryEvent, func(ctx *fiber.Ctx) {
panic("y tho")
})
app.All("/", func(ctx *fiber.Ctx) {
if hub := sentryfiber.GetHubFromContext(ctx); hub != nil {
hub.WithScope(func(scope *sentry.Scope) {
scope.SetExtra("unwantedQuery", "someQueryDataMaybe")
hub.CaptureMessage("User provided unwanted query string, but we recovered just fine")
})
}
ctx.Status(fiber.StatusOK)
})
app.Listen(":3000")
```
### Accessing Context in `BeforeSend` callback
```go
sentry.Init(sentry.ClientOptions{
Dsn: "your-public-dsn",
BeforeSend: func(event *sentry.Event, hint *sentry.EventHint) *sentry.Event {
if hint.Context != nil {
if ctx, ok := hint.Context.Value(sentry.RequestContextKey).(*fiber.Ctx); ok {
// You have access to the original Context if it panicked
fmt.Println(ctx.Hostname())
}
}
return event
},
})
```
