mongoose-lean-id

Attach id to the results of mongoose queries when using .lean()

(This fork prevents crash when _id is missing. Also using for loop for optimization.)

Usage

const mongooseLeanId = require('mongoose-lean-id');

examples

It attaches .id to result of find, findOne, and findOneAndUpdate if lean

    const schema = new mongoose.Schema({
      name: String
    });

    schema.plugin(mongooseLeanId);

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

    return Model.create({ name: 'test' }).
      then(() => Promise.all([
        Model.find().lean(),
        Model.findOne().lean(),
        Model.findOneAndUpdate({}, { name: 'test' }).lean()
      ])).
      then(results => {
        const [findRes, findOneRes, findOneAndUpdateRes] = results;
        assert.equal(findRes[0].id, findRes[0]._id.toHexString());
        assert.equal(findOneRes.id, findOneRes._id.toHexString());
        assert.equal(findOneAndUpdateRes.id,
          findOneAndUpdateRes._id.toHexString());
      });
