Function scopeExit

Create a scope exit handle that will call the provided callback when disposed, to be used with using or await using.

For example, this code:

import {scopeExit} from "lifecycle-utils";

function example() {
    using exitHandle = scopeExit(() => {
        console.log("exiting scope");
    });
    console.log("inside scope");
}

async function asyncExample() {
    await using exitHandle = scopeExit(async () => {
        await new Promise((resolve) => setTimeout(resolve, 100));
        console.log("exiting async scope");
    });
    console.log("inside async scope");
}

example();
console.log("example done");
console.log()

await asyncExample();
console.log("asyncExample done");
Copy

Will print this:

inside scope
exiting scope
example done

inside async scope
exiting async scope
asyncExample done
Copy
