Exercise Weekend

Before the first week of class, take time to ensure all necessary tools and frameworks are correctly installed on your personal machine, including those we will use later on in the course.

The JavaScript course will require the following tools and technologies. You are expected to install any tools you do not already have before the course begins. Confirm each tool is functioning properly by following all instructions below.


Installation Instructions

Installation instructions for Node.js, and its corresponding package manager (npm) may be found in the Installing Node.js lesson.


Confirm that node and npm are in place by checking versions:

  • Run the command $ node -v in your home directory. You should receive an output of 4.0.x or higher.
  • Run the command $ npm -v in your home directory. You should receive an output of 3.6.x or higher.

Confirm Node.js is functioning correctly by creating a small test project:

Create a test project directory and JavaScript file. This example will use a hello.js file in a directory called hello:

console.log("hello world");

Next, use Node.js to execute this file from the command line:

$ node hello.js

If all is functioning, you should see "hello world" (or whatever you placed in the console.log() of your JavaScript file) printed to the terminal.

If you encounter any issues installing any of these tools, there will be an opportunity to receive setup assistance from Epicodus staff the first Tuesday of the course at 10:30am. Even though we are not yet using these frameworks, it's important to set these tools up now, so that you may take advantage of installation and setup assistance if any errors occur.
