k-mongoose-json-select v1.0.2

mongoose-json-select

A mongoose plugin to limit JSON properties and set the unselected fields to null.

var jsonSelect = require('k-mongoose-json-select');

var schema = Schema({
  name: String,
  email: String,
  created: {type: Date, default: Date.now}
});
schema.plugin(jsonSelect, 'name created');
var User = mongoose.model('User', schema);

var user = User({name: 'alice', email: 'alice@example.com'});
JSON.stringify(user);
// -> '{"name": "alice", "email": null , "created": "2013-03-16T16:08:38.065Z"}'

JSON.stringify(user.toJSON({select: 'name email'}));
// -> '{"name": "alice", "email": "alice@example.com", "created": null }'

Installation

$ npm install k-mongoose-json-select

Usage

Inclusion/Exclusion

// inclusion. these are equivalent
schema.plugin(jsonSelect, 'name.first');
schema.plugin(jsonSelect, {'name.first': 1});

// exclusion. these are equivalent
schema.plugin(jsonSelect, '-name.last');
schema.plugin(jsonSelect, {'name.last': 0});

Always exclude _id,id and __v field if the field is not included explicitly.

schema.plugin(jsonSelect, 'name');  // contains 'name' only

Configures default fields as a plugin option or schema option.

// these are equivalent
schema.plugin(jsonSelect, 'name');

schema.plugin(jsonSelect);
schema.set('toJSON', {select: 'name'});

Specifies fields when calling toJSON.

// this overrides a default configuration
JSON.stringify(doc.toJSON({select: 'name email'}));

The syntax for fields is the same with mongoose's Query#select.
