Yarn

Yarn is a package manager for your code.

- Open Source
In my case, I like to use pnpm to reduce the disk size of the node_modules folder. Therefore, the example of the Next.js Docker image uses this package manager, but you can make slight adjustments to use npm or yarn if you prefer.

Webpack

Webpack is a module bundler. Its main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.
Pricing:
- Open Source
For its part, Next.js is the most popular React framework. As any other JavaScript application that uses a bundler such as webpack or Vite, for production a compiled version of the project is used. This is known as build. A build aims to provide the minimum amount of code needed for the application to function the same as it does in development. This ensures that JavaScript files are very lightweight, allowing the browser to fetch and interpret them in the shortest possible time to render the user interface or perform whatever tasks the application requires.".

Node.js

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications

Every Docker image starts from a base image. In this case, any JavaScript project that runs a server, will need a runtime like Node.js. We'll take as base the Docker image of a Node.js version that is compatible with our project. In my case, I like to use the Alpine version of the images, since this is more lightweight. However, we have to check that there are no compatibility issues when building the image, otherwise, we have to use the "non-Alpine" version of the image. For this example, I use the node:22.6.0-alpine3.19 image as base.
