func Cors(origin string) web.Middleware

Cors sets the response headers needed for Cross-Origin Resource Sharing

func Errors

Logger writes some information about the request to the logs in the format: TraceID : (200) GET /foo -> IP ADDR (latency)

func Metrics

func Panics

func Panics() web.Middleware

Panics recovers from panics and converts the panic to an error so it is reported in Metrics and handled in Errors.
