Embedded Backend Example

A single-file Go example that runs the Traceway backend and an OTel-instrumented Gin app in one process. No external databases required — everything runs on SQLite.

What it does

1. Starts the Traceway backend on :8082 with a pre-seeded user and project
2. Configures an OTLP HTTP trace exporter that sends spans to the backend
3. Runs a Gin server on :8080 with a single /hello/:name endpoint that creates a child span and optionally records an error

Running

go build .
./embedded-backend-otel

Then try:

• http://localhost:8080/hello/world — successful request with a db.lookup span
• http://localhost:8080/hello/error — request that records an error with stack trace

Open the dashboard at http://localhost:8082 and log in with admin@localhost.com / admin to see the traces.
