sails-mongo

Sails.js/Waterline adapter for MongoDB. (See compatibility for more details.)

Provides easy access to MongoDB from Sails.js & Waterline. This module is a Sails/Waterline adapter maintained by the core team. Its goal is to provide robust, easy-to-use access to MongoDB from Sails.js and Waterline.

As an adapter, this module implements a set of declarative interfaces, conventions, and best-practices for integrating with Mongo databases. Strict adherence to an adapter specification enables the (re)use of built-in generic test suites, standardized documentation, reasonable expectations around the API for your users, and overall, a more pleasant development experience for everyone.

Installation

To install this adapter, run:

$ npm install sails-mongo

Then connect the adapter to one or more of your app's datastores.

Usage

Visit Models & ORM in the docs for more information about using models, datastores, and adapters in your app/microservice. For a low-level usage example, check out the tutorial.

Compatibility

This version of the adapter has been tested with MongoDB versions 3.6, 4.0, and 4.2. It uses MongoDB 3.5.x connection options. If you're upgrading from an older version, note that there are some updated, changed, new and deprecated options.

This adapter implements the following methods:

Method	Status	Layer
registerDatastore	Implemented	N/A
teardown	Implemented	N/A
validateModelDef	Implemented	Modeled
createRecord	Implemented	Modeled (DML)
createEachRecord	Implemented	Modeled (DML)
updateRecords	Implemented	Modeled (DML)
destroyRecords	Implemented	Modeled (DML)
findRecords	Implemented	Modeled (DQL)
join	not supported	Modeled (DQL)
countRecords	Implemented	Modeled (DQL)
sumRecords	Implemented	Modeled (DQL)
avgRecords	Implemented	Modeled (DQL)
definePhysicalModel	Implemented	Migratable
dropPhysicalModel	Implemented	Migratable
setPhysicalSequence	not supported	Migratable

Development and Test

This repository includes a Docker Compose file that helps setting up the environment needed to run the test.

The npm test command expects a local MongoDB instance running.

For convenience, some new npm scripts are available:

• npm run start-mongodb: Starts MongoDB docker instance
• npm run stop-mongodb: Stops MongoDB docker instance
• npm run mongodb-shell: Runs the MongoDB shell CLI, connects to the instance started by the npm run start-mongodb command.

This simplifies development as you do not need to have a MongoDB instance running on the development computer.

Notice that if you do have a local MongoDB instance, then, there might be port conflicts if you run the docker version. The docker version is configured to run on the standard port 27017.

The normal development workflow would now be:

• When starting a development session, npm run start-mongdb
• Now we can execute npm test as many times as needed
• When finishing a development session, npm run stop-mongdb

The npm run docker-test command runs the tests on a single run under the latest MongoDB version (at the time 4.2). It automatically starts a MongoDB docker instance, and it stops it. This is useful for one time local tests. Note that since this command stops MongoDB, npm test will fail.

When running automation tests in Travis, the module is tested under a combination of Node.js 10, 12, 14 and MongoDB: 3.6, 4.0, 4.2.

When running automation tests in AppVeyor, the module is tested under a combination of Node.js 10, 12, 14 and the MongoDB version that AppVeyor supports. Multiple MongoDB version are not tested in AppVeyor.

For more information, check MongoDB's Support Policy.

To run tests while developing, you can run npm run docker. This command opens a docker instance and opens a shell. From there you can run npm test to run the tests as many times as you need.

Special thanks

Thanks so much to Ted Kulp (@tedkulp) and Robin Persson (@prssn) for building the first version of this adapter back in 2013. Since then, it has evolved into a core adapter within the framework.
