loopback-connector-mongodb

MongoDB connector for loopback-datasource-juggler.

Usage

To use it you need loopback-datasource-juggler@1.0.x.

1. Setup dependencies in package.json:

   {
     ...
     "dependencies": {
       "loopback-datasource-juggler": "1.0.x",
       "loopback-connector-mongodb": "1.0.x"
     },
     ...
   }
   

2. Use:

       var DataSource = require('loopback-datasource-juggler').DataSource;
       var ds = new DataSource('mongodb');
       ...
   

About MongoDB _id field

MongoDB uses a specific ID field with BSON ObjectID type, named _id

This connector does not expose MongoDB _id by default, to keep consistency with other connectors. Instead, it is transparently mapped to the id field - which is declared by default in the model if you do not define any id.

If you wish to still be able to access _id property, you must define it explicitely as your model ID, along with its type.

Example :

var ds = app.dataSources.db;
MyModel = ds.createModel('mymodel', {
    _id: { type: ds.ObjectID, id: true }
});

*Example with a Number _id :

MyModel = ds.createModel('mymodel', {
    _id: { type: Number, id: true }
});

Customizing MongoDB configuration for tests/examples

By default, examples and tests from this module assume there is a MongoDB server instance running on localhost at port 27017.

To customize the settings, you can drop in a .loopbackrc file to the root directory of the project or the home folder.

The .loopbackrc file should be in JSON format, for example:

{
    "dev": {
        "mongodb": {
            "host": "127.0.0.1",
            "database": "test",
            "username": "youruser",
            "password": "yourpass",
            "port": 27017
        }
    },
    "test": {
        "mongodb": {
            "host": "127.0.0.1",
            "database": "test",
            "username": "youruser",
            "password": "yourpass",
            "port": 27017
        }
    }
}

Note: username/password is only required if the MongoDB server has authentication enabled.

Running tests

npm test

Release notes

• 1.1.7 - Do not return MongoDB-specific _id to client API, except if specifically specified in the model definition
