Functions

func DefaultValue 

func DefaultValue(name string) (string, bool)

DefaultValue looks up the default value

func Name 

func Name(field string) string

Name gets the environment variable Name for a config schema field

func TryName 

func TryName(field string) string

TryName gracefully tries to get the environment variable Name for a config schema field

ConfigSchema records the schema of configuration at the type level

A note on Feature Flags

Feature flags should be used during development of large features that might span more than one release cycle. Most changes that are not considered "complete" when a PR is merged and might affect node operation should be put behind a feature flag.

This also allows to disable large parts of the code that may not be needed for all deployments that could introduce attack surface area if it is not needed.

Good example usage is for alternative blockchain support, new services like Feeds Manager, external initiators and so on. https://app.shortcut.com/chainlinklabs/story/33622/remove-legacy-config

type EnvVar 

type EnvVar[T any] struct {
	// contains filtered or unexported fields
}

EnvVar is an environment variable parsed as T.

func New 

func New[T any](name string, parse func(string) (T, error)) *EnvVar[T]

New creates a new EnvVar for the given name and parse func. name must match the ConfigSchema field.

func NewBool added in v1.4.0 

func NewBool(name string) *EnvVar[bool]

func NewDuration added in v1.4.0 

func NewDuration(name string) *EnvVar[time.Duration]

func NewInt64 added in v1.4.0 

func NewInt64(name string) *EnvVar[int64]

func NewString added in v1.4.0 

func NewString(name string) *EnvVar[string]

func NewUint16 added in v1.4.0 

func NewUint16(name string) *EnvVar[uint16]

func NewUint32 added in v1.4.0 

func NewUint32(name string) *EnvVar[uint32]

func NewUint64 added in v1.4.0 

func NewUint64(name string) *EnvVar[uint64]

func (*EnvVar[T]) Parse 

func (e *EnvVar[T]) Parse() (v T, invalid string)

Parse attempts to parse the value returned from the environment, falling back to the default value when empty or invalid.

func (*EnvVar[T]) ParseFrom 

func (e *EnvVar[T]) ParseFrom(get func(string) string) (v T, invalid string, err error)

ParseFrom attempts to parse the value returned from calling get with the env var name, falling back to the default value when empty or invalid.

func (*EnvVar[T]) ParsePtr added in v1.6.0 

func (e *EnvVar[T]) ParsePtr() *T

ParsePtr attempts to parse the value from the environment, returning nil if the env var was empty or invalid.
