How to create private class instance variables without using experimental features in JavaScript.

I explain how to hide internal functions and variables from the consumer of the class

I had a friend tell me the other day that they figured out how to use an API. What they explained to me they instantiated class objects as required, but then they were manipulating properties and/or using functions that were prefixed with the _ character. As you may or may not know, there is an implicit contract dictating that properties that have names beginning with _ shall not be accessed, altered, or even invoked. I believe that this implicit contract isn’t always sufficient and it isn’t defensive programming. People, like my friend, can and do break the implicit contract when consuming a library.

Tools for Seeding Databases in Node.js

Multiple tools for seeding a database for projects, personal and or professional.

In this post, I’ll be discussing some tools I’ve found and used for different projects of mine. Why would we want to seed a database? There are typically a couple of reasons to seed a database. First, having data in your database is typically helpful for tests that need to hit the database. The second reason to seed a database is to show off a project, for example, a portfolio piece or an internal demonstration of something you developed for your company. There are two categories of tools I’m listing. A data-oriented tool, and a few avatars tools.

How to Auto reload a full stack JavaScript project using nodemon and webpack dev server

A couple of weeks ago, when I was under the pressure of time, I decided to attempt to get webpack-dev-server (WDS) running. I failed miserably, and moved on instead of wasting time on the project. Now again, I find myself in need of a tool to speed up development time. Last week I did the research and today I’m sharing for posterity’s sake. Additionally at the time of this article webpack-livereload-plugin is not compatible with webpack 4 that was just released a few days ago. The only downside to this configuration is I cannot use socket.io to communicate between nodemon’s server and WDS’s client.
