Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user

router.post('/product/:product_id', passportConf.isAuthenticated, (req, res, next) => {
    Cart.findOne({owner: req.user._id}, (err, cart) => {
        cart.items.push({
            item: req.body.product_id,
            price: parseFloat(req.body.priceValue),
            quantity: parseInt(req.body.quantity)
        });

        cart.total = (cart.total + parseFloat(req.body.priceValue)).toFixed(2);

Objective: we want to send email to user upon registration welcoming them.
packages to use: nodemailer to send emails https://nodemailer.com/ and mailtrap to trap the messages sent in developement and not sent to the users https://mailtrap.io/


steps:
1 install nodemailer to your nodejs project https://www.npmjs.com/package/nodemailer
2 create a new file in your utils folder

calvin-puram

objective: we want to remove the duplicates error we have in our routes i.e in the catch block of every route since they are all thesame we want to create a middleware that will dirrect such errors directely to our global error handler
steps:
1 create a new file may in your utils folder and called it anything
2 we will use this code snippet which is just a middleware that resolve a promise

module.exports = fn => {
  return (req, res, next) => Promise.resolve(fn(req, res, next)).catch(next);
};

3 next we will import this into all our routes and use it like this:
