Quick and dirty mongoose crud interface.

_README.md

Example usage

const express = require('express');
const List = require('../models/list');
const Crud = require('./crud');

const list = new Crud(List, { queryKey: 'publicId' });
const router = express.Router();
module.exports = router;

router.get('/', list.find(), (req, res) => res.jsonp(req.result));
router.post('/', list.create(), (req, res) => res.jsonp(req.result));
router.get('/:publicId', list.findOne(), (req, res) => res.jsonp(req.result));
router.put('/:publicId', list.update(), (req, res) => res.jsonp(req.result));
// TODO: router.delete('/:publicId', list.delete()); 

Obviously you'll need to add security layer!

mongoose-crud.js

class Crud {
  constructor(collection, { db, resultKey = 'result', queryKey = 'id' } = {}) {
    this.collection = collection;
    this.queryKey = queryKey;
    this.resultKey = resultKey;
  }

  findOne = () => (req, res, next) => {
    this.collection.findOne({ [this.queryKey]: req.params[this.queryKey] }).then(doc => {
      req[this.resultKey] = doc;
      next();
    }).catch(next);
  }

  find = () => (req, res, next) => {
    this.collection.find().then(docs => {
      req[this.resultKey] = docs;
      next();
    }).catch(next);
  }

  create = () => (req, res, next) => {
    const c = new this.collection(req.body);
    c.save().then(doc => {
      req[this.resultKey] = doc;
      next();
    }).catch(next);
  }

  update = () => (req, res, next) => {
    this.collection.findAndModify({
      query: { [this.queryKey]: req.params[this.queryKey] },
      update: { $set: req.body },
      new: true
    }).then(doc => {
      req[this.resultKey] = doc;
      next();
    }).catch(next);
  }
}

module.exports = Crud;
