Node.js
Node-specific APIs and runtime behavior.
- fs/promises and node:pathReading and writing files with Node's promise-based file system API, and building paths safely with the path module.
- node:http — A Minimal HTTP ServerNode's built-in HTTP server module — request/response handling with no framework, and why every input from it is untrusted.
- package.json and package-lock.jsonpackage.json describes a Node project's scripts and dependencies; package-lock.json pins the exact versions actually installed, for reproducibility.
- package.json exportsExplicitly declares a package's public entry points — anything not listed isn't importable by consumers, making internal refactoring safe.
- StreamsProcesses data in chunks as it arrives, instead of loading an entire file or response into memory at once.
