This frame comes with a wide range of features including nested slides, Markdown support, automatic animation, PDF export, speaker notes, LaTeX support, and syntax highlighting code.
Reveal.js on Ubuntu 20.04
Before starting the Reveal.js installation it will be necessary that we first install some necessary packages. To do this, we will have to open a terminal (Ctrl + Alt + T) and execute the following command in it:
sudo apt install curl gnupg2 unzip git
The next step we will need to take is install NodeJS version 14, although version 10 onwards should work too. For this we have to add the nodejs repository, which we can do by typing in the same terminal:
curl -sL https://deb.nodesource.com/setup_14.x | sudo bash -
This will start the whole process of adding the repository along with your GPG key. Once the process is finished, we can install NodeJS with the following command:
sudo apt install nodejs
When the installation is finished, we will be able to check installed version of NodeJS executing the following command:
Download and install Reveal.js
At this point, it’s time to start the download. To do this, we will clone Reveal.js repository using Git. To do this we will only have to open a terminal (Ctrl + Alt + T) and execute the following command:
git clone https://github.com/hakimel/reveal.js.git
When the cloning is done, on our computer we will find a folder called revel.js. To access it e install the app, we will only have to use the following commands in the terminal (Ctrl + Alt + T):
cd reveal.js sudo npm install
Once all the application dependencies are installed, we can now run it using the following command:
The above command will indicate that the service will be provided through port 8000, which is the default port, along with the server’s IP address. Now, we just have to open our favorite web browser and go to http: // server-ip: 8000. In this direction we will see the default presentation of reveal.js, which will indicate that the installation has been a success.
We will also be able change port using –port as follows:
npm start -- --port=8001
