DefjsCore
createSSEInterceptor
Wraps an SSEInterceptorFn as a tagged SSEInterceptor.
@defjs/core · Function
Signature
function createSSEInterceptor(fn: SSEInterceptorFn): SSEInterceptor;
Returns { kind: 'sse', fn }. SSE interceptors run only for SSE operations, in
registration order; next(req) opens the stream through the remaining
interceptors.
A deterministic URL error from next(req) rejects the returned promise, so
.then or .catch recovery runs; if it is not recovered, the operation
still reports REQ_BUILD_FAILED.
EventStreamHandle extends AsyncDisposable. A structural short-circuit
implementation must provide [Symbol.asyncDispose](): PromiseLike<void> and
connect it to the same close lifecycle.
Parameters
Prop
Type
fn SSEInterceptorFnSSE interceptor function.
Returns
An SSEInterceptor with kind: 'sse'.
