Project dependencies (as opposed to dev-dependencies) are those packages required for the application to run.You can read more about the differences between the two here.In this tutorial, we’ll have a look at getting started with the mysql module — a driver for My SQL, written in Java Script.

Consider the following insert stored procedure with an out parameter: DELIMITER $$ CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_insert_employee`( out employee_id int, in employee_name varchar(25), in employee_location varchar(25) ) BEGIN insert into employees(name, location) values(employee_name, employee_location); set employee_id = LAST_INSERT_ID(); END As you may have noticed, a couple of people in the comments are suggesting using an ORM.No SQL databases are all the rage these days and probably the preferred back-end for applications.But you shouldn’t architect your next project based on what’s hip and trendy, rather the type of database to be used should depend on the project’s requirements.Here’s a contrived example using Sequelize: Whether or not using an ORM makes sense for you, will depend very much on what you are working on and with whom.On the one hand, ORMS tend to make developers more productive, in part by abstracting away a large part of the SQL so that not everyone on the team needs to know how to write super efficient database specific queries.
