method

async_hooks.AsyncLocalStorage.snapshot AsyncLocalStorage.snapshot()); const result = asyncLocalStorage.run(321, () => runInAsyncScope(() => asyncLocalStorage.getStore())); console.log(result); // returns 123 ``` AsyncLocalStorage.snapshot() can replace the use of AsyncResource for simple async context tracking purposes, for example: ```js class Foo { #runInAsyncScope = AsyncLocalStorage.snapshot(); get() { return this.#runInAsyncScope(() => asyncLocalStorage.getStore()); } } const foo = asyncLocalStorage.run(123, () => new Foo()); console.log(asyncLocalStorage.run(321, () => foo.get())); // returns 123 ```" data-algolia-static="true" data-algolia-merged="false" data-type="Method">static snapshot(): (fn: (...args: TArgs) => R, ...args: TArgs) => R;Captures the current execution context and returns a function that accepts a function as an argument. Whenever the returned function is called, it calls the function passed to it within the captured context.

const asyncLocalStorage = new AsyncLocalStorage(); const runInAsyncScope = asyncLocalStorage.run(123, () => AsyncLocalStorage.snapshot()); const result = asyncLocalStorage.run(321, () => runInAsyncScope(() => asyncLocalStorage.getStore())); console.log(result); // returns 123 AsyncLocalStorage.snapshot() can replace the use of AsyncResource for simple async context tracking purposes, for example:

class Foo { #runInAsyncScope = AsyncLocalStorage.snapshot(); get() { return this.#runInAsyncScope(() => asyncLocalStorage.getStore()); } } const foo = asyncLocalStorage.run(123, () => new Foo()); console.log(asyncLocalStorage.run(321, () => foo.get())); // returns 123 @returnsA new function with the signature (fn: (...args) : R, ...args) : R.
