Interface: RenderContext

Defined in: interfaces/AsyncContent.ts:58

Passed as the last argument to every async-capable content hook, so a consumer can abandon work the UI no longer needs.

Existing synchronous hooks simply ignore it — a one-argument callback stays assignable, and nothing about its timing changes.

Example

renderNodeExtra: async (node, { signal }) => {
    const res = await fetch(`/enrich/${node.id}`, { signal })
    return renderChips(await res.json())
}

Methods

isStale()

isStale(): boolean

Defined in: interfaces/AsyncContent.ts:71

true once this render has been superseded. A cheap guard for consumers doing non-abortable work, so they can bail out between steps without touching RenderContext.signal.

Returns

boolean

Properties

signal

readonly signal: AbortSignal

Defined in: interfaces/AsyncContent.ts:65

Aborted when this render is superseded — the tooltip hid or reopened for another element, the selection changed, the panel was refreshed or removed, the graph was destroyed. Forward it to fetch and in-flight requests are cancelled instead of leaked.
