JavaScript Inheritance Patterns

Leave a reply
In this post, I am going to introduce to you 3 different ways of how you can implement inheritance in JavaScript. You will see inheritance implemented in languages such as Java by allowing a class to inherit state and behavior from a superclass, where each superclass can have many subclasses. This means that in Java an object is an instance of a class, which can inherit other classes. Now in JavaScript, being prototypal by nature, an object can inherit from an object. For the rest of this post, I will introduce the Pseudoclassical, Functional and Prototypal inheritance patterns in JavaScript.

How to configure Java heap size for node.js JDBC module?

Leave a reply

In my node.js application, I'm using JDBC to connect to a Oracle database. I need to increase my java heap space to prevent following error:

java.lang.OutOfMemoryError: Java heap space

I know that there is a terminal option for setting maximum Java heap size (-Xmx<size>) but the problem is, I don't explicitly run java, it happens inside my JDBC module (which depends on java module), so I can't use that terminal option.

So how java heap size can be configured in my case?
