Functions

func DeserializeJson

func DeserializeJson[T any](data []byte) (T, error)

func GetTokenClaims

func GetTokenClaims(tokenString string, signingKey string) (map[string]interface{}, error)

func InitLogger

func InitLogger() func(*zap.Logger)

func LoadConfiguration

func LoadConfiguration[T Configuration](configFilePath string, config T) error

LoadConfiguration loads configuration data from a JSON file into the provided 'config' struct. The 'config' struct should implement the 'Configuration' interface. If a 'ValidateJws' method is present on the 'config' struct, it will be called after loading to ensure configuration validity.

Returns an error if there's an issue reading the file, unmarshalling the JSON, or if validation fails.

func LoadEnvironmentVariables

func LoadEnvironmentVariables[T Configuration](config T) error

LoadEnvironmentVariables loads configuration data from environment variables into the provided 'config' struct. The 'config' struct should implement the 'Configuration' interface. struct tags with the "env" key are used to map environment variables to struct fields. If a 'ValidateJws' method is present on the 'config' struct, it will be called after loading to ensure configuration validity.

Returns an error if there's an issue processing environment variables or if validation fails.

func Log

func Log(lvl zapcore.Level, template string, args ...interface{})

func LogError

func LogError(template string, args ...interface{})

func LogInfo

func LogInfo(template string, args ...interface{})

func LogWarn

func LogWarn(template string, args ...interface{})

func NewBearerToken

func NewBearerToken(signingKey string) ([]byte, error)

func SerializeJson

func SerializeJson(data interface{}) (string, error)

func ValidateBearerToken

func ValidateBearerToken(tokenString string, signingKey string) (bool, error)

Types

type Configuration

type Configuration interface {
	Validate() error
}

Configuration represents a type that can be loaded with configuration data and optionally validated.
