Possible Errors and recovery

Bad Shutdown: (Unable to lock file: /data/db/mongod.lock)

Occasionally, mongo will be improperly shutdown, like closing the terminal before exiting

$ ctrl + c

And you’ll see the following error

cklanac

const createError = require("http-errors");
const debug = require("debug")("app:auth:jwt");

const jwtHelper = require("../helpers/jwt");

function jwtAuth(req, res, next) {
  const auth = req.header("Authorization");

  if (!auth) {
    debug("'Authorization' header not found");

const chai = require('chai');
const chaiHttp = require('chai-http');
const faker = require('faker');
const mongoose = require('mongoose');

// this makes the should syntax available throughout
// this module
const should = chai.should();

const {Restaurant} = require('../models');

For this challenge you will run through a set of CRUD operation with Mongo.

Getting Started

To get started, you will need to create a noteful database with a notes collection and populate it with documents.

• Copy the contents of this gist into a JSON file and import it using mongoimport. Note, the data in ths gist is formatted as a proper JSON array of objects, so the import process is slightly different that the Restaurants data used earlier. Below is the mongoimport command with --jsonArray flag.

mongoimport -d noteful -c notes --drop --jsonArray --file ~/
