# Migration Guide | Sentry for Fiber

## [How to move from `raven-go` to `sentry-go`](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#how-to-move-from-raven-go-to-sentry-go)

### [Installation](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#installation)

raven-go

```bash
go get github.com/getsentry/raven-go
```

sentry-go

```bash
go get github.com/getsentry/sentry-go
```

### [Configuration](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#configuration)

raven-go

```go
import "github.com/getsentry/raven-go"

func main() {
	raven.SetDSN("___PUBLIC_DSN___")
}
```

sentry-go

```go
import (
	"fmt"
	"github.com/getsentry/sentry-go"
)

func main() {
	err := sentry.Init(sentry.ClientOptions{
		Dsn: "___PUBLIC_DSN___",
		// Adds request headers and IP for users,
        // visit: https://docs.sentry.io/platforms/go/data-management/data-collected/ for more info
        SendDefaultPII: true,
	})

	if err != nil {
		fmt.Printf("Sentry initialization failed: %v\n", err)
	}
}
```

raven-go

```go
SetDSN()
SetDefaultLoggerName()
SetDebug()
SetEnvironment()
SetRelease()
SetSampleRate()
SetIgnoreErrors()
SetIncludePaths()
```

sentry-go

```go
sentry.Init(sentry.ClientOptions{
	Dsn: "___PUBLIC_DSN___",
	DebugWriter: os.Stderr,
	Debug: true,
	Environment: "environment",
	Release: "my-project-name@1.0.0",
	SampleRate: 0.5,
	// IgnoreErrors: TBD,
	// IncludePaths: TBD
})
```

Available options: see [Configuration](https://docs.sentry.io/platforms/go/configuration/options.md) section.

#### [Providing SSL Certificates](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#providing-ssl-certificates)

By default, TLS uses the host's root CA set. If you don't have `ca-certificates` (which should be your go-to way of fixing the missing certificates issue) and want to use `gocertifi` instead, you can provide pre-loaded cert files as one of the options to `sentry.Init` call:

```go
package main

import (
	"log"

	"github.com/certifi/gocertifi"
	"github.com/getsentry/sentry-go"
)

sentryClientOptions := sentry.ClientOptions{
	Dsn: "___PUBLIC_DSN___",
}

rootCAs, err := gocertifi.CACerts()
if err != nil {
	log.Println("Couldn't load CA Certificates: %v\n", err)
} else {
	sentryClientOptions.CaCerts = rootCAs
}

sentry.Init(sentryClientOptions)
```

### [Usage](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#usage)

#### [Capturing Errors](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#capturing-errors)

raven-go

```go
f, err := os.Open("filename.ext")
if err != nil {
	raven.CaptureError(err, nil)
}
```

sentry-go

```go
f, err := os.Open("filename.ext")
if err != nil {
	sentry.CaptureException(err)
}
```

#### [Capturing Panics](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#capturing-panics)

raven-go

```go
raven.CapturePanic(func() {
	// do all of the scary things here
}, nil)
```

sentry-go

```go
func() {
	defer sentry.Recover()
	// do all of the scary things here
}()
```

#### [Capturing Messages](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#capturing-messages)

raven-go

```go
raven.CaptureMessage("Something bad happened and I would like to know about that")
```

sentry-go

```go
sentry.CaptureMessage("Something bad happened and I would like to know about that")
```

#### [Capturing Events](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#capturing-events)

raven-go

```go
packet := &raven.Packet{
	Message: "Hand-crafted event",
	Extra: &raven.Extra{
		"runtime.Version": runtime.Version(),
		"runtime.NumCPU": runtime.NumCPU(),
	},
}
raven.Capture(packet)
```

sentry-go

```go
event := sentry.NewEvent()
event.Message = "Hand-crafted event"
event.Extra["runtime.Version"] = runtime.Version()
event.Extra["runtime.NumCPU"] = runtime.NumCPU()

sentry.CaptureEvent(event)
```

#### [Additional Data](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#additional-data)

See Context section.

#### [Event Sampling](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#event-sampling)

```go
raven.SetSampleRate(0.25)
```

sentry-go

```go
sentry.Init(sentry.ClientOptions{
	// ...
	SampleRate: 0.25,
})
```

#### [Awaiting the response (not recommended)](https://docs.sentry.io/platforms/go/guides/fiber/migration.md#awaiting-the-response-not-recommended)

```go
raven.CaptureMessageAndWait("Something bad happened and I would like to know about that")
```

sentry-go

```go
sentry.CaptureMessage("Something bad happened and I would like to know about that")

if sentry.Flush(time.Second * 2) {
