Functions ¶

func Available ¶

func Available(fn js.Value) bool

Available returns true if fn is a callable JavaScript value.

func AwaitPromise ¶

func AwaitPromise(promise js.Value, thenCb, catchCb js.Func)

AwaitPromise attaches promise completion callbacks through a JS-owned helper when available. The helper defers callback execution away from the current JS event frame for TinyGo asyncify builds.

func Call ¶

func Call(target js.Value, method string, args ...any) js.Value

Call calls target[method](...args), using a JS-owned helper when available.

func New ¶

func New(ctor js.Value, args ...any) js.Value

New constructs ctor with args, using a JS-owned helper when available.

func RejectionMessage ¶

func RejectionMessage(value js.Value) string

RejectionMessage returns a conservative error message for a JS promise rejection. Bldr's TinyGo helper passes numeric error classes instead of raw browser Error objects to avoid TinyGo stringifying arbitrary JS values.

func UseHelpers ¶

func UseHelpers() bool

UseHelpers reports whether TinyGo-specific JavaScript helpers may be used.

Types ¶
