What you'll learn

Building robust file handling systems in Node.js requires more than basic read/write operations. Modern applications need efficient async I/O, stream processing for large datasets, and secure file management workflows that scale in cloud environments. In this course, Node.js: File System, Streams, Async I/O, Uploads, and Pipes, you'll learn to build production-ready file handling systems using the latest Node.js patterns and APIs. First, you'll explore modern async/await file operations with the fs/promises API and ES modules. Next, you'll discover how to use streams for memory-efficient processing of large files and implement back-pressure handling. Finally, you'll learn how to create secure file upload workflows, pipe data between streams, and build automated file watching systems. When you're finished with this course, you'll have the skills and knowledge of Node.js file operations needed to build scalable, cloud-ready applications with efficient file handling capabilities.
