Learn how to set up highlight.io on your Go chi backend.
1
Set up your frontend Highlight snippet.
This backend SDK requires one of the Highlight frontend SDKs to be installed, so please make sure you've followed the fullstack mapping guide first.
H.init("<YOUR_PROJECT_ID>", {
tracingOrigins: ['localhost', 'example.myapp.com/backend'],
networkRecording: {
enabled: true,
recordHeadersAndBody: true,
},
});
2
Install the Highlight Go SDK.
Install the highlight-go package with go get.
go get -u github.com/highlight/highlight/sdk/highlight-go3
Initialize the Highlight Go SDK.
H.Start starts a goroutine for recording and sending backend errors. Setting your project id lets Highlight record errors for background tasks and processes that aren't associated with a frontend session.
import (
H "github.com/highlight/highlight/sdk/highlight-go"
)
func main() {
// ...
H.SetProjectID("<YOUR_PROJECT_ID>")
H.Start()
defer H.Stop()
// ...
}4
Add the Highlight middleware.
highlightChi.Middleware is a Go Chi compatible middleware.
import (
highlightChi "github.com/highlight/highlight/sdk/highlight-go/middleware/chi"
)
func main() {
// ...
r := chi.NewRouter()
r.Use(highlightChi.Middleware)
// ...
}5
Record custom errors. (optional)
If you want to explicitly send an error to Highlight, you can use the H.RecordError method.
H.RecordError(ctx, err, attribute.String("key", "value"))6
Verify your errors are being recorded.
Make a call to H.RecordError to see the resulting error in Highlight.
func TestErrorHandler(w http.ResponseWriter, r *http.Request) {
H.RecordError(r.Context(), errors.New("a test error is being thrown!"))
}7
Set up logging.
Start sending logs to Highlight! Follow the logging setup guide to get started.
