This page is meant to be an up-to-date, comprehensive list of all of the core adapters available for the Sails.js framework, and a reference of a few of the most robust community adapters out there.
All supported adapters can be configured in roughly the same way: by passing in a Sails/Waterline adapter (
adapter), as well as a connection URL (
url). For more information on configuring datastores, see sails.config.datastores.
Having trouble connecting? Be sure to check your connection URL for typos. If that doesn't work, review the documentation for your database provider, or get help.
The following core adapters are maintained, tested, and used by the Sails.js core team.

|Database technology||Adapter||Connection URL structure||For production?|
|Local disk / memory||(built-in, see sails-disk)||n/a||No!|
MySQL is the world's most popular relational database.
npm install sails-mysql --save
adapter: 'sails-mysql', url: 'mysql://user:[email protected]:port/database',
- The default port for MySQL is
- If you plan on saving special characters—like emojis—in your data, you may need to set the
charsetconfiguration option for your datastore. To allow emojis, use
charset: 'utf8mb4'. You may use the
columnTypesetting in a model attribute to set the character set.
- For relational database servers like MySQL and PostgreSQL, you may have to create a "database" first using a free tool like SequelPro or in the MySQL REPL on the command-line (if you're an experience SQL user). It's customary to make a database specifically for your app to use.
- The sails-mysql adapter is also 100% compatible with Amazon Aurora databases.
If you find yourself encountering a "Handshake inactivity timeout" error when your Sails app interacts with MySQL, you can increase the timeout using the
connectTimeout option. This is usually only necessary when queries are running side-by-side with computationally expensive operations (for example, compiling client-side typescript files or running webpack during development).
For example, you might extend the timeout to 20 seconds:
adapter: 'sails-mysql', url: 'mysql://user:[email protected]:port/database', connectTimeout: 20000
PostgreSQL is a modern relational database with powerful features.
npm install sails-postgresql --save
adapter: 'sails-postgresql', url: 'postgresql://user:[email protected]:port/database',
- The default port for PostgreSQL is
- In addition to
url, you might also need to set
ssl: true. This depends on where your PostgreSQL database server is hosted. For example,
ssl: trueis required when connecting to Heroku's hosted PostgreSQL service.
MongoDB is the leading NoSQL database.
npm install sails-mongo --save
adapter: 'sails-mongo', url: 'mongodb://user:[email protected]:port/database',
- The default port for MongoDB is
- If your Mongo deployment keeps track of its internal credentials in a separate database, then you may need to name that database by tacking on
?authSource=theotherdbto the end of the connection URL.
Write to your computer's hard disk, or a mounted network drive. Not suitable for at-scale production deployments, but great for a small project, and essential for developing in environments where you may not always have a database set up. This adapter is bundled with Sails and works out of the box with zero configuration.
You can also operate
sails-disk in memory-only mode. See the settings table below for details.
Available out of the box in every Sails app.
Configured as the default database, by default.
||The directory to place database files in. The adapter creates one file per model.||
- You can configure the default
sails-diskadapter by adding settings to the
Is your database not supported by one of the core adapters? Good news! There are many different community database adapters for Sails.js and Waterline available on NPM.
