Dockerize your Development Environment in Node.js

Using Docker in your development workflow has a positive impact on your productivity. It eliminates the typical “It worked on my machine” type of bugs and the setup on a different machine only requires a running Docker daemon and nothing else. Before we get started implementing we will go over Docker real quick.

What is Docker?

Docker is a platform that can run containers, packages of software. To run these containers Docker uses OS-level virtualization. You can think of a container as a lightweight version of a virtual machine.

All containers you run on your Docker platform are isolated from one another. For example, the host, on which Docker runs, and one container running on the host, do not share the same filesystem except to explicitly tell them to.

To start a container you need a Docker image. This image is the blueprint for your container. You can take already predefined images from Docker-Hub or configure your own ones by writing a so-called Dockerfile.

This is just a quick overview of Docker if you want to dig deeper I encourage you to start here.

Why would you dockerize your development workflow?

In the introduction, I already touched on one benefit of using Docker in your development environment. This being the fact that it gets rid of the typical “It works on my machine” issue. Some other benefits are:

  • Standardize development workflow between team members even more
  • Reduction of production-only bugs if you use Docker for deployment too (Configurations between production and development can be quite similar)
  • Getting rid of the forementioned “Works on my machine” type of bugs

What Garbage Collection in JavaScript Is and How It Works

JavaScript values are allocated when things are created (objects, Strings, etc.) and freed automatically when they are no longer used. This process is called Garbage collection.
