Logging in Go / Fiber
Learn how to set up highlight.io Go log ingestion with fiber.
1
Set up your frontend highlight.io integration.
First, make sure you've followed the frontend getting started guide.
2
Call logrus methods while passing the request context.
The request context allows highlight to associate logs with the incoming frontend session and network request.
logrus.WithContext(c.Context()).WithField("user", "bob").Infof("hello, %s!", "world")
3
Call the Highlight logging SDK.
Use our SDK to configure logrus, and use it as normal.
package main
import (
"context"
"github.com/highlight/highlight/sdk/highlight-go"
"github.com/highlight/highlight/sdk/highlight-go/log"
"github.com/sirupsen/logrus"
)
func main() {
// setup the highlight SDK
highlight.SetProjectID("<YOUR_PROJECT_ID>")
highlight.Start(
highlight.WithServiceName("my-fiber-app"),
highlight.WithServiceVersion("git-sha"),
)
defer highlight.Stop()
// setup highlight logrus hook
hlog.Init()
// if you don't want to get stdout / stderr output, add the following uncommented
// hlog.DisableOutput()
app := fiber.New()
app.Use(logger.New())
// setup go fiber to use the highlight middleware for header parsing
app.Use(highlightFiber.Middleware())
app.Get("/", func(c *fiber.Ctx) error {
// in handlers, use logrus with the UserContext to associate logs with the frontend session.
logrus.WithContext(c.Context()).Infof("hello from highlight.io")
return c.SendString("Hello, World!")
})
logrus.Fatal(app.Listen(":3456"))

Verify your backend logs are being recorded.
Visit the highlight logs portal and check that backend logs are coming in.
