How to Install Reveal.js on NixOS latest

Reveal.js is an open-source, HTML presentation framework which is popular for its modern look and interactive features. It's used by developers, educators, and even politicians for creating visually stunning and engaging slideshows.

If you're using NixOS latest and would like to use Reveal.js for your next presentation, follow the steps below:

Step 1: Install Nix Package Manager

If you haven't already installed Nix Package Manager, you can do so by running the following command in your terminal:

$ curl https://nixos.org/nix/install | sh

This will download and install Nix on your system.

Step 2: Create a new Nix environment

In order to install and use Reveal.js, it's recommended that you create a new Nix environment. This can be done by creating a new file in your home directory, such as nix-shell.nix, with the following contents:

{ pkgs ? import <nixpkgs> {} }:

pkgs.mkShell {
  buildInputs = [
    pkgs.nodejs-14_x
  ];
}

This file tells Nix to create a new shell environment with Node.js installed.

Step 3: Activate the new Nix environment

To activate the new Nix environment, run the following command in your terminal:

$ nix-shell

This will download and install all of the necessary dependencies for your new environment.

Step 4: Install Reveal.js

Once your new Nix environment is active, you can install Reveal.js by running the following command in your terminal:

$ npm install reveal.js

This will download and install Reveal.js in your current working directory.

Step 5: Run the demo presentation

To make sure that Reveal.js is installed and working properly, you can run the demo presentation that comes with the framework. Navigate to the Reveal.js directory that was created during installation and run the following command:

$ npm start

This will open up a new browser window with the demo presentation loaded.

Conclusion

By following the steps outlined in this tutorial, you should now have Reveal.js installed and ready to use on your NixOS latest system. With its easy-to-use syntax and powerful features, Reveal.js is a great choice for creating interactive and engaging presentations.
