What you'll learn

Node.js was built to run on a single thread using non-blocking I/O calls. Building apps for this environment requires extensive use of asynchronous code. In this course, Async Patterns in Node.js, you'll learn multiple techniques to write efficient asynchronous code using modern JavaScript. First, you’ll explore how the Node event loop works and how to write asynchronous code with callbacks that adhere to conventions followed in the Node community. Next, you’ll discover how to use Promises and the async/await keywords to write asynchronous code that’s easier to read. Finally, you’ll learn how to write event-driven code with EventEmitters and use worker threads to tackle CPU-intensive tasks in your Node apps. When you’re finished with this course, you’ll have the skills and knowledge of asynchronous programming necessary to build performant Node apps using accepted best practices.
