const express = require('express');
const morgan = require('morgan');
const mongoose = require('mongoose');
const Blog = require('./models/blog');

// express app
const app = express();

// connect to mongodb & listen for requests

const dbURI = "mongodb+srv://<username>:<password>@nodetutor.jpayl.mongodb.net/?retryWrites=true&w=majority";

mongoose.connect(dbURI, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(result => app.listen(3000))
  .catch(err => console.log(err));

// register view engine
app.set('view engine', 'ejs');

// middleware & static files
app.use(express.static('public'));
app.use(express.urlencoded({ extended: true }));
app.use(morgan('dev'));
app.use((req, res, next) => {
  res.locals.path = req.path;
  next();
});

// routes
