If you want to program just for the joy of creating, LiveView will be an excellent opportunity for you. This programming model keeps your brain firmly on the server and lets you explore one concept at a time. Layering on graphics makes this kind of exploratory programming almost magical.

Programmers learn by writing code, and that’s exactly how this course will work. We’ll work on a project together as if we’re a fictional game company. You’ll write lots of code, starting with small tweaks of generated code and building up to major enhancements that extract common features with components.

As you build the application, you’ll encounter more complexity. A distributed dashboard will show a real-time view of other users and processes. You’ll even build a game from scratch—because that’s the best way to learn how to layer the most sophisticated LiveView applications.

Building Real-Time Web Applications with Phoenix LiveView

LiveView meets all of the interactivity and real-time needs of your average single-page app while being easy to build and maintain. 
The first step toward developing LiveView applications is to install Phoenix, Erlang, Elixir, Node, and Postgres. Elixir is the language we’ll be using, and Erlang is the language it’s built on. Phoenix is the web framework, while Node supports the system JavaScript that LiveView uses, and PostgreSQL is the database our examples will use. 

> **Note:** Everything is already installed on the Educative platform.

# Getting started with the Phoenix project
With all of our dependencies installed, we’re ready to start building the Pento app. We’ll begin by setting up a new Phoenix project.
