I'm having trouble installing Sails. What should I do?

Start with NPM's helpful troubleshooting guide. If you continue to have problems, and you've tried Google searching but you're still stumped, please carefully review the updated Sails contribution guide and then create a GitHub issue in the Sails repo.

What are the dependencies of Sails?

Dependency Status

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 is tested with node versions 0.10.x and up, though, we recommend using The latest LTS version of Node. The framework is built on the rock-solid foundations of Express and 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.

Sails Flagship users: We manually verify every dependency of Sails and other officially-maintained modules by hand, every single week. This includes core hooks, adapters, generators, client SDKs, and Flagship packages. We regularly send security/compatibility reports about dependencies to the primary email address associated with your account. If you'd like additional people on your team to receive these reports, no problem! Just let us know their email addresses and we'll get them set up. (These email addresses will also receive communications about patches, shrinkwrap updates, and compatibility notices.)

If you have questions or concerns about our dependencies, talk to a core team member. Please do not submit a pull request changing the version of a dependency without first (1) checking that dependency's changelog, (2) verifying compatibility, and (3) submitting an accompanying PR to update roadstead, our dependency wallah.

Who else is using Sails.js?

Sails is used in production by individuals and companies, non-profits, and government entities all over the world, for all sorts of projects (greenfield and mature). You can see some examples here of companies that have used Sails for their projects. (This small list is definitely not authoritative, so if you're using Sails in your app/product/service, we'd love to hear about it!

Where do I get help?

Where do I submit ideas? Report bugs?

The Sails project tracks bug reports in GitHub issues and uses pull requests for feature proposals. Please read the contribution guide before you create an issue, submit a proposal, or begin working on pull request.

What version of Sails should I use?

NPM version

Unless you are a contributor running a pre-release version of the framework in order to do some testing or work on core, you should use the latest stable version of Sails from NPM (click the badge above). Installing is easy- just follow these instructions.

Note: to install/upgrade to the latest version of Sails locally in an existing project, run npm install sails@latest --save. If you are having trouble and are looking for a bazooka, you might also want to run rm -rf node_modules && npm cache clear && npm install sails@latest --force --save && npm install.

If you are looking to install a pre-release version of Sails, you can install from the beta tag on npm (i.e. npm install sails@beta). This is a great way to try out a coming release ahead of time and start upgrading before the release becomes official. The beta npm release candidate corresponds with the beta branch in the Sails repo. (Just be sure to also use the right version of your favorite adapters and other plugins. If in doubt, feel free to ask.)

Finally, if you like living on the edge, or you're working on adding a feature or fixing a bug in Sails, install the edge version from the master branch on github. The edge version is not published on the registry since it's constantly under development, but you can still use npm to install it (e.g. npm install sails@git://

For more instructions on installing the beta and edge versions of Sails, check out the contribution guide.

How do I get involved?

There are many different ways to contribute to Sails; for example you could help us improve the official documentation, write a plugin, answer StackOverflow questions, start a Sails meetup, help troubleshoot GitHub issues, write some tests, or submit a patch to Sails core or one of its dependencies. Please look through the contribution guide before you get started. It's a short read that covers guidelines and best practices that ensure your hard work will have the maximum impact.

How does the documentation end up on the Sails website?

The documentation is compiled from the markdown files in the sails repo on github. A number of Sails users have expressed interest in emulating the process we use to generate the pages on the Sails website. Good news is it's pretty simple: The compilation process for the Sails docs involves generating HTML from Markdown files in the sails repo, then performing some additional transformations such as adding data type bubbles, tagging permalinks for individual sections of pages, building JSON data to power the side navigation menu and setting HTML <title> attributes for better search engine discoverability of individual doc pages. See the doc-templater module for more information.

Where is the documentation for the different releases of Sails?

The documentation on the main website is for the latest stable npm release of Sails, and is mirrored by the docs in the master branch of the sails repo on github (Master is sometimes a few commits ahead, but any critical documentation updates make it onto the website within a day or two.)

For older releases of Sails that are still widely used, the documentation is compiled from the relevant sails-docs branches and hosted on the following subdomains:
