process.release

process.release

An Object containing metadata related to the current release, including URLs for the source tarball and headers-only tarball.

process.release contains the following properties:

• name: a string with a value that will always be 'node' for Node.js. For legacy io.js releases, this will be 'io.js'.
• sourceUrl: a complete URL pointing to a .tar.gz file containing the source of the current release.
• headersUrl: a complete URL pointing to a .tar.gz file containing only the header files for the current release. This file is significantly smaller than the full source file and can be used for compiling add-ons against Node.js.
• libUrl: a complete URL pointing to an node.lib file matching the architecture and version of the current release. This file is used for compiling add-ons against Node.js. This property is only present on Windows builds of Node.js and will be missing on all other platforms.

e.g.

{ name: 'node',
  sourceUrl: 'https://nodejs.org/download/release/v4.0.0/node-v4.0.0.tar.gz',
  headersUrl: 'https://nodejs.org/download/release/v4.0.0/node-v4.0.0-headers.tar.gz',
  libUrl: 'https://nodejs.org/download/release/v4.0.0/win-x64/node.lib' }

In custom builds from non-release versions of the source tree, only the name property may be present. The additional properties should not be relied upon to exist.
