Episode notes
http.Handler vs. http.HandlerFunc
- Prefer using
http.Handlerfor simpler type handling and easier integration with third-party libraries. - Consider long argument lists in constructors for explicit dependency management, but functional options are a valid alternative.
Airport Encounter
- Mat Ryer met Tom Wilkie, CTO of Grafana, at an airport after a missed connection.
- This encounter led to a discussion about Go and eventually to Mat's current job at Grafana Labs.
Functional Options Pattern
- Use functional options pattern for constructor arguments to specify only necessary overrides.
- This approach increases readability by focusing on non-default configurations, according to Johnny Boursiquot.
