We have learned again and again over the years to take versioning of dependencies very seriously. We lock Sails’s dependency versions and only bump those versions if the associated updates fix a security issue or present other substantive advantages to Sails users (improved compatibility, performance, etc.) In addition, the core maintainers of Sails are committed to fixing any major security, performance, or stability bugs that arise in any of our core dependencies– regardless of whether those modules are officially maintained by another entity or not.

Sails are tested with node versions 0.10.x and up, though we recommend using at least Node v4.0.0. The framework is built on the rock-solid foundations of Express and Socket.io. Out of the box, it also depends on other great modules, like grunt, waterline, and fs-extra. Click the badge above for the full list of dependencies in the latest stable release of Sails core.
