mongoose-throw-unselected

Throws an error whenever you access a field on a mongoose document that is not selected

Usage

const mongooseThrowUnselected = require('mongoose-throw-unselected');

examples

It throws an error if accessing a field that is not included in the projection

If you explicitly exclude a field (like via .select() on a query) and you access that field, this plugin will throw an error. This plugin adds a custom setter on each field that checks if the field is included by checking isSelected().

const schema = new mongoose.Schema({
  name: {
    first: String,
    last: String,
  },
  age: Number
});

schema.plugin(mongooseThrowUnselected);

const Model = mongoose.model('Person', schema);

return Model.create({ name: { first: 'Valeri', last: 'Karpov' }, age: 28 }).
  // Explicitly exclude 'name.first'
  then(() => Model.findOne().select({ 'name.first': false })).
  then(doc => {
    assert.throws(() => doc.name.first);
    assert.doesNotThrow(() => doc.name);
    assert.equal(doc.name.last, 'Karpov');
    assert.equal(doc.age, 28);
  });
