callback-to-async-await A utility library for converting callback-based functions to async/await syntax in JavaScript.

Installation npm install callback-to-async-await Usage convertCallbackToAsync Converts a callback-based function to an async function that returns a Promise.

const { convertCallbackToAsync } = require("callback-to-async-await");

const callbackFunction = (callback) => { setTimeout(() => { callback({ data: [1, 2, 3] }); }, 1000); };

const promiseFunction = convertCallbackToAsync(callbackFunction);

(async () => { const data = await promiseFunction(); console.log(data); })(); convertCallbackToAsyncWithError Converts a callback-based function that follows the (error, result) convention to an async function that returns a Promise.

const { convertCallbackToAsyncWithError } = require("callback-to-async-await");

const callbackFunction = (callback) => { setTimeout(() => { callback(null, { data: [1, 2, 3] }); }, 1000); };

const promiseFunction = convertCallbackToAsyncWithError(callbackFunction);

(async () => { try { const data = await promiseFunction(); console.log(data); } catch (error) { console.error("Error:", error); } })(); API convertCallbackToAsync(functionToCall) functionToCall: The callback-based function to be converted. Returns an async function that returns a Promise. convertCallbackToAsyncWithError(functionToCall) functionToCall: The callback-based function to be converted. Returns an async function that returns a Promise. If the original callback function returns an error as the first argument, the Promise will be rejected with that error. Otherwise, the Promise resolves with the result.
