This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

CRUD = Create, Read, Update, Delete

$dbname = 'test';
$username = 'root';

	# Backup
	docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql

	Validation Errors and Rollback
	A common use case is to rollback a transaction if there are validation errors. For example consider this service:

	import grails.validation.ValidationException
	class AuthorService {

	void updateAge(id, int age) {
	def author = Author.get(id)
	author.age = age
	if (!author.validate()) {

	// 🔥 Node 7.6 has async/await! Here is a quick run down on how async/await works

	const axios = require('axios'); // promised based requests - like fetch()

	function getCoffee() {
	return new Promise(resolve => {
	setTimeout(() => resolve('☕'), 2000); // it takes 2 seconds to make coffee
	});
	}
