What Node.js does
Node.js is an open-source JavaScript runtime built on V8 for command-line tools, servers, build systems, and applications. Its event loop and asynchronous APIs can support concurrent I/O, but throughput, latency, scalability, and safety depend on application design, native dependencies, workload, runtime flags, and infrastructure; this page makes no generic performance claim. Node supports CommonJS and ECMAScript modules with version- and package-specific interoperability rules.
This record pins Node.js 26.8.1, which the Node.js project classified as the Current release line on 2026-08-30—not an LTS release. Production users should choose a supported release line based on the project's published lifecycle and their dependency support, then plan upgrades before end of life. The Windows x64 and ARM64 MSI files and macOS PKG are installers; the Linux x64 and ARM64 tar.xz files are upstream binary archives that must be placed and managed deliberately rather than treated as distribution packages.
The project publishes SHA-256 values in SHASUMS256.txt and detached GPG signatures for that manifest. The values below are transcribed from the publisher manifest; this audit did not verify its signature or run the packages. npm is bundled with the official distribution, but registry packages are third-party code with separate maintainers, licenses, lifecycle, install scripts, and supply-chain risk. Installing the runtime can be offline; retrieving npm dependencies, Corepack tools, documentation, updates, or remote services requires connectivity unless those materials are separately cached and verified.
