Package middleware implements middleware functions. It contains both app-specific middleware functions, as well as more generic ones.

func AttachUserAndLogger[Ctx context.Context, In, Out any](h th.Handler[MyAppContext, In, Out]) th.Handler[Ctx, In, Out]

AttachUserAndLogger fetches and attaches the user ID and attaches a request-specific logger.

func SetHandlerTimeout[Ctx tc.TypedContext[Ctx], In, Out any](timeout time.Duration, h th.Handler[Ctx, In, Out]) th.Handler[Ctx, In, Out]

SetHandlerTimeout returns a new handler with its timeout set to timeout.

type MyAppContext struct {
	context.Context
	UserID UserID
	Logger logrus.FieldLogger
}

MyAppContext contains the UserID and a request-specific logger.

func (mac MyAppContext) InnerContext() context.Context

InnerContext implements the typedcontext.TypedContext interface.

func (mac MyAppContext) WithInnerContext(ctx context.Context) MyAppContext

WithInnerContext implements the typedcontext.TypedContext interface.

type UserID int64

UserID represents the ID of the user. You'd probably have UserID somewhere else than in the middleware package though.

func UserIDFromString(s string) (UserID, error)

UserIDFromString translates s into an UserID if it is valid.
