Functions

func GetBinding 

func GetBinding(name string) js.Value

GetBinding gets a value of an environment binding.

func GetCtx added in v0.0.11 

func GetCtx(name string) js.Value

func GetRuntimeContextValue added in v0.0.11 

func GetRuntimeContextValue(name string) js.Value

func GetTriggerObject added in v0.0.11 

func GetTriggerObject(ctx context.Context) js.Value

func Getenv 

func Getenv(name string) string

func PassThroughOnException 

func PassThroughOnException()

PassThroughOnException prevents a runtime error response when the Worker script throws an unhandled exception. Instead, the request forwards to the origin server as if it had not gone through the worker. see: https://developers.cloudflare.com/workers/runtime-apis/fetch-event/#passthroughonexception

func WaitUntil 

func WaitUntil(task func())

WaitUntil extends the lifetime of the "fetch" event. It accepts an asynchronous task which the Workers runtime will execute before the handler terminates but without blocking the response. see: https://developers.cloudflare.com/workers/runtime-apis/fetch-event/#waituntil
