# Official Sentry Echo Handler for Sentry-go SDK
**go.dev:** https://pkg.go.dev/github.com/getsentry/sentry-go/echo
**Example:** https://github.com/getsentry/sentry-go/tree/master/_examples/echo
## Installation
```sh
go get github.com/getsentry/sentry-go/echo
```
```go
import (
"fmt"
"net/http"
"github.com/getsentry/sentry-go"
sentryecho "github.com/getsentry/sentry-go/echo"
"github.com/labstack/echo/v4"
"github.com/labstack/echo/v4/middleware"
)
// To initialize Sentry's handler, you need to initialize Sentry itself beforehand
if err := sentry.Init(sentry.ClientOptions{
Dsn: "your-public-dsn",
}); err != nil {
fmt.Printf("Sentry initialization failed: %v\n", err)
}
// Then create your app
app := echo.New()
app.Use(middleware.Logger())
app.Use(middleware.Recover())
// Once it's done, you can attach the handler as one of your middleware
app.Use(sentryecho.New(sentryecho.Options{}))
// Set up routes
app.GET("/", func(ctx echo.Context) error {
return ctx.String(http.StatusOK, "Hello, World!")
})
// And run it
app.Logger.Fatal(app.Start(":3000"))
```
## Configuration
`sentryecho` 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 true,
// as echo includes its own Recover middleware that handles http responses.
Repanic bool
// WaitForDelivery configures whether you want to block the request before moving forward with the response.
// Because Echo's `Recover` handler doesn't restart the application,
// it's safe to either skip this option or set it to `false`.
WaitForDelivery bool
// Timeout for the event delivery requests.
Timeout time.Duration
```
## Usage
`sentryecho` attaches an instance of `*sentry.Hub` (https://pkg.go.dev/github.com/getsentry/sentry-go#Hub) to the `echo.Context`, which makes it available throughout the rest of the request's lifetime.
You can access it by using the `sentryecho.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 `sentryecho`!**
```go
app := echo.New()
app.Use(middleware.Logger())
app.Use(middleware.Recover())
app.Use(sentryecho.New(sentryecho.Options{
Repanic: true,
}))
app.Use(func(next echo.HandlerFunc) echo.HandlerFunc {
return func(ctx echo.Context) error {
if hub := sentryecho.GetHubFromContext(ctx); hub != nil {
hub.Scope().SetTag("someRandomTag", "maybeYouNeedIt")
}
return next(ctx)
}
})
app.GET("/", func(ctx echo.Context) error {
if hub := sentryecho.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")
})
}
return ctx.String(http.StatusOK, "Hello, World!")
})
app.GET("/foo", func(ctx echo.Context) error {
// sentryecho handler will catch it just fine. Also, because we attached "someRandomTag"
// in the middleware before, it will be sent through as well
panic("y tho")
})
app.Logger.Fatal(app.Start(":3000"))
```
### Accessing Request 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 req, ok := hint.Context.Value(sentry.RequestContextKey).(*http.Request); ok {
// You have access to the original Request here
}
}
return event
},
})
```
