Node.js Style Guide

Node.js Style Guide is an opinionated reference for writing consistent, readable JavaScript and Node.js code. It defines formatting conventions such as two-space indentation, Unix line endings, semicolons, single quotes, and an 80-character line limit. Naming rules cover variables, functions, classes, properties, and constants. The guide also recommends practices for conditionals, object creation, functions, comments, module imports, getters, setters, and method chaining. Several sections focus on maintainability, including writing small functions, returning early, naming closures, and avoiding modifications to built-in prototypes. Example code contrasts preferred and discouraged patterns so the reasoning can be applied directly. Configuration files for tools such as JSHint and EditorConfig help automate parts of the style guide.
