The PromiseHandle exported from this package extends the Promise class to expose the resolve and reject functions passed through the constructor as member functions.
Here's a few examples on how to use the promise-handle package.
| After 🥳 | Before 😭 |
|---|---|
import { PromiseHandle } from "promise-handle";
const handle = new PromiseHandle();
emitter.on("even", handle.resolve);
await handle; |
await new Promise((resolve) => {
emitter.on("even", (event) => {
resolve(event);
});
}); |
import { PromiseHandle } from "promise-handle";
const handle = new PromiseHandle();
await something({
callback() {
handle.resolve();
}
});
await handle; |
let inner;
const callback = new Promise((resolve) => {
inner = something({
callback() {
resolve();
}
});
});
await inner;
await callback; |
I've written and added this small utility class into five code-bases already and I thought I might as well get it into the NPM registry to get it handy next time around.
