Functions

func Middleware

func Middleware(logger *zap.Logger, options ...MiddlewareOption) echo.MiddlewareFunc

Middleware returns a new middleware using the provided logger.

func MiddlewareWithConfig

func MiddlewareWithConfig(config MiddlewareConfig) echo.MiddlewareFunc

MiddlewareWithConfig calls config.ToMiddleware returning the middleware if no error, if error is returned a panic is raised.

Types

type MiddlewareConfig

type MiddlewareConfig struct {
	// Logger defines the logger to write to.
	Logger *zap.Logger

	// Skipper defines a function to skip middleware.
	Skipper middleware.Skipper

	// CustomTimeFormat defines the time format the log should use.
	// Default time format is unix time.
	CustomTimeFormat string

	// ExtraFields defines additional fields to be added to the log.
	ExtraFields []zapcore.Field

	// ExtraFieldsHook allows for additional fields to be added dynamically.
	ExtraFieldsHook func(echo.Context) []zapcore.Field
}

MiddlewareConfig defines the config for Zap middleware.

func (MiddlewareConfig) ToMiddleware

func (config MiddlewareConfig) ToMiddleware() (echo.MiddlewareFunc, error)

ToMiddleware converts Config to middleware or returns an error for invalid configuration.

type MiddlewareOption

type MiddlewareOption func(c *MiddlewareConfig)

MiddlewareOption sets the middleware function definition.

func WithCustomTimeFormat

func WithCustomTimeFormat(format string) MiddlewareOption

WithCustomTimeFormat sets the middleware CustomTimeFormat config option.

func WithExtraFields

func WithExtraFields(fields []zapcore.Field) MiddlewareOption

WithExtraFields sets the middleware ExtraFields config option.

func WithExtraFieldsHook

func WithExtraFieldsHook(hook func(echo.Context) []zapcore.Field) MiddlewareOption

WithExtraFieldsHook sets the middleware ExtraFieldsHook config option.

func WithSkipper

func WithSkipper(skipper middleware.Skipper) MiddlewareOption

WithSkipper sets the middleware Skipper config option.

func (*ZapLogger) Panicj

func (l *ZapLogger) Panicj(j log.JSON)

Panicj implements echo's Logger interface.

func (*ZapLogger) Prefix

func (l *ZapLogger) Prefix() string

Prefix returns an empty string as zap doesn't expose the underlying named logger.

func (*ZapLogger) Print
