@solana/promises

This package contains helpers for using JavaScript promises.

Functions

$3

Returns a new promise that will reject if the abort signal fires before the original promise settles. Resolves or rejects with the value of the original promise otherwise.

``ts
const result = await getAbortablePromise(
// Resolves or rejects when fetch settles.
fetch('https://example.com/json').then(r => r.json()),
// ...unless it takes longer than 5 seconds, after which the AbortSignal is triggered.
AbortSignal.timeout(5000),
);
`

$3

An implementation of Promise.race` that causes all of the losing promises to settle. This allows them to be released and garbage collected, preventing memory leaks.
