Prod configures the DI for providng database connectivity

Functions

func New

func New(
	cfg Config,
	logs *zap.Logger,
	epresolver aws.EndpointResolverWithOptions,
	tp trace.TracerProvider,
	pr propagation.TextMapPropagator,
) (acfg aws.Config, err error)

New initialize an AWS config to be used to create clients for individual aws services. We would like run this during fx lifecycle phase to provide it with a context because it can block. But too many dependencies would have to wait for it.

Types

type Config

type Config struct {
	// LoadConfigTimeout bounds the time given to config loading
	LoadConfigTimeout time.Duration `env:"LOAD_CONFIG_TIMEOUT" envDefault:"100ms"`
	// DynamoEndpoint allows configuring the dynamodb endpoint for testing because it supports a local version
	DynamoEndpoint *url.URL `env:"DYNAMO_ENDPOINT"`
}

Config configures this package
