Functions

func GetenvDefault

func GetenvDefault(key, defaultValue string) string

GetenvDefault returns the value of environment variable called by key. If the value is undefined or in other words empty, then value of given defaultValue is returned.

func IsCI

func IsCI() bool

IsCI returns true if environment variable CI has value true and false otherwise.

func IsDevelopment

func IsDevelopment() bool

IsDevelopment checks environment variable ENV and returns true only if ENV value is `development`.

func IsProduction

func IsProduction() bool

IsProduction checks the value of environment variable ENV and returns true if value is `production`.

func Must

func Must[T any](value T, err error) T

Must checks for given err. If err is not nil panic is called, otherwise returns value T.

func RandInt64

func RandInt64() (int64, error)

RandInt64 returns cryptographically secure random number.

func TLSConfig

func TLSConfig(getCertificate GetCertificate) *tls.Config

TLSConfig returns secure TLS configuration for Internet server.

Types

type GetCertificate

type GetCertificate func(*tls.ClientHelloInfo) (*tls.Certificate, error)

GetCertificate returns a Certificate based on the given ClientHelloInfo.

func GetCertificateFromFiles

func GetCertificateFromFiles(certFile, keyFile string) GetCertificate

GetCertificateFromFiles loads GetCertificate func from given TLS cert files.

func GetCertificateFromLetsEncrypt

func GetCertificateFromLetsEncrypt(m *autocert.Manager) GetCertificate

GetCertificateFromLetsEncrypt loads GetCertificate func from given Let's Encrypt Manager.

func GetCertificateFunc

func GetCertificateFunc(m *autocert.Manager, devCertFile, devKeyFile string) GetCertificate

GetCertificateFunc loads certificates for development or production depending on return value of function [kkn.fi/infra#IsProduction].

Deprecated: GetCertificateFunc is deprecated.

func GetCertificateFuncFromFiles

func GetCertificateFuncFromFiles(certFile, keyFile string) GetCertificate

GetCertificateFuncFromFiles loads GetCertificate func from given TLS cert files.
