Streams

Streams process data piece by piece, allowing you to handle massive files without running out of memory.

Overview

Streams process data piece by piece, allowing you to handle massive files without running out of memory.

Code Example

import fs from "node:fs";\nconst readable = fs.createReadStream("large-file.mp4");\nreadable.pipe(res); // Stream directly to the HTTP response

Web Development Context

In modern web development, understanding Streams is crucial. Node.js is widely used for building APIs, real-time applications, and microservices. Mastery of this concept allows you to build efficient, scalable, and secure backend systems.

Common Mistakes

• Blocking the event loop with heavy synchronous tasks.
• Exposing secrets in code instead of environment variables.
• Forgetting to handle promise rejections.
