Node.js is an open-source, cross-platform JavaScript runtime environment that enables developers to execute JavaScript code outside of web browsers. The project is governed through an open governance model with support from the OpenJS Foundation, and it maintains a Technical Steering Committee composed of voting members, regular members, and emeriti members who guide the project's direction and decision-making.
The repository implements a structured release strategy with three distinct release types. Current releases are under active development with a new major version released every six months in April and October, allowing for breaking changes. LTS releases, which occur on even-numbered major versions, receive 12 months of active support followed by 18 months of maintenance, providing stability and security focus for production environments. Nightly releases are built every 24 hours from the Current branch when changes are present, intended for testing purposes. All releases follow semantic versioning and are cryptographically signed by Release Team members, with verification possible through SHA checksums and PGP signatures available in download directories.
Node.js emphasizes collaborative contribution through its Code of Conduct and governance documentation, with clear expectations that contributors engage constructively. The project provides comprehensive support resources, API documentation available at nodejs.org/api, and detailed building instructions for developers who want to compile Node.js from source. Security vulnerabilities are handled through a dedicated security reporting process documented in SECURITY.md. The repository's classification spans multiple domains including web frameworks, runtime environments, APIs, server-side scripting, and event-driven programming, reflecting its broad applicability across the JavaScript development landscape. The project's focus on non-blocking I/O, asynchronous programming, and the V8 engine positions it as a foundational technology for scalable network applications and the broader npm ecosystem.
