slog.Group

A focused look at the slog.Group function in Go's standard library logging package. slog.Group creates an Attr that nests multiple key-value pairs under a single key. With TextHandler, grouped attributes appear in dot-separated notation (e.g., req.method=GET); with JSONHandler, they appear as nested JSON objects. The post includes a practical code example logging HTTP request details grouped under a 'req' key alongside status and duration fields.
