Each model controller:

import { crudControllers } from '../../utils/crud'
import { Item } from './item.model'

export default crudControllers(Item)

You are able to override default methods from crudController:

export default {
  ...crudControllers(Item),
  removeOne() {...}
}

model:

 import mongoose from 'mongoose'

const itemSchema = new mongoose.Schema(
  {
    name: {
      type: String,
      required: true,
      trim: true,
      maxlength: 50
    },
    status: {
      type: String,
      required: true,
      enum: ['active', 'complete', 'pastdue'],
      default: 'active'
    },
    notes: String,
    due: Date,
    createdBy: {
      type: mongoose.SchemaTypes.ObjectId,
      ref: 'user',
      required: true
    },
    list: {
      type: mongoose.SchemaTypes.ObjectId,
      ref: 'list',
      required: true
    }
  },
  { timestamps: true }
)

// 1: means sorting order
// order matters, list first, then name
itemSchema.index({ list: 1, name: 1 }, { unique: true })

export const Item = mongoose.model('item', itemSchema)

CrudController:

export const getOne = model => async (req, res) => {
  try {
    const doc = model
      .findOne({ createdBy: req.user._id, _id: req.params.id })
      .lean()
      .exec()

    if (!doc) {
      return res.status(400).end()
    }

    res.status(200).json({ data: doc })
  } catch (e) {
    console.error(e)
    res.status(400).end()
  }
}

const getMany = model => async (req, res) => {
  try {
    const docs = model
      .find({ createdBy: req.user._id })
      .lean()
      .exec()

    res.status(200).json({ data: docs })
  } catch (e) {
    console.error(e)
    res.status(400).end()
  }
}

export const createOne = model => async (req, res) => {
  const createdBy = req.user._id
  try {
    const doc = await model.create({ ...req.body, createdBy })
    res.status(201).json({ data: doc })
  } catch (e) {
    console.error(e)
    res.status(400).end()
  }
}

export const updateOne = model => async (req, res) => {
  try {
    const updatedDoc = await model
      .findOneAndUpdate(
        {
          createdBy: req.user._id,
          _id: req.params.id
        },
        req.body,
        { new: true }
      )
      .lean()
      .exec()

    if (!updatedDoc) {
      return res.status(400).end()
    }

    res.status(200).json({ data: updatedDoc })
  } catch (e) {
    console.error(e)
    res.status(400).end()
  }
}

export const removeOne = model => async (req, res) => {
  try {
    const removed = await model.findOneAndRemove({
      createdBy: req.user._id,
      _id: req.params.id
    })

    if (!removed) {
      return res.status(400).end()
    }

    return res.status(200).json({ data: removed })
  } catch (e) {
    console.error(e)
    res.status(400).end()
  }
}

export const crudControllers = model => ({
  removeOne: removeOne(model),
  updateOne: updateOne(model),
  getMany: getMany(model),
  getOne: getOne(model),
  createOne: createOne(model)
})
