NixOS: Sandbox and Reproducible Builds

We have gone through a lot when configuring our computers with a language, with an editor, and maybe even setting up Git. For every project, though, we may need a different set of tools. In one, you may require Java 17 with a particular version of Kotlin. Another will require an npm of a specific version. You could use something like SDKMan for Java or a node version manager for Node. The problem is that you must install it and ensure you do it correctly for every project. The global installation won’t cut it; the more complex your project dependencies, the more tedious it will get. Nix provides consistent installation of tools so that it gets it right every time and for every project. It manages all project dependencies so you can consistently build your project.
