mongoose-lean-getters

Apply getters on lean() documents: https://mongoosejs.com/docs/tutorials/lean.html

Usage

const mongoose = require('mongoose');
const mongooseLeanGetters = require('mongoose-lean-getters');

const schema = mongoose.Schema({
  name: {
    type: String,
    // Get the last 6 characters of the string
    get: v => v.slice(-6)
  }
});
// Add this plugin to apply getters when using `lean()`.
schema.plugin(mongooseLeanGetters);

await Model.create({ name: 'Captain Jean-Luc Picard' });

const doc = await Model.findOne().lean({ getters: true });
doc.name; // 'Picard'

You may also set the default lean options to always use getters:

const mongoose = require('mongoose');
const mongooseLeanGetters = require('mongoose-lean-getters');

const schema = mongoose.Schema({
  name: {
    type: String,
    // Get the last 6 characters of the string
    get: v => v.slice(-6)
  }
});
// Set the default options for all lean queries
schema.plugin(mongooseLeanGetters, { defaultLeanOptions: { getters: true }});

await Model.create({ name: 'Captain Jean-Luc Picard' });

const doc = await Model.findOne().lean();
doc.name; // 'Picard'

// You may also set getters: false at call time
const doc2 = await Model.findOne().lean({ getters: false });
doc2.name; // 'Captain Jean-Luc Picard'
