Set up lab for React on Windows

React is a popular JavaScript library for building user interfaces (UI). React is a declarative way to create reusable components for your website. There are many other popular libraries for JavaScript-based front-end development. We'll use a few of these libraries while creating our lab. Redux is a library that provides predictable state container for JavaScript apps and is often used in compliment with React. JSX is a library syntax extension to JavaScript often used with React to describe what the UI should look like. NodeJS is a convenient way to run a webserver for your React application.

This article will show how to install Visual Studio 2019 for your development environment, and the tools, and libraries needed for a React web development class.

Lab configuration

To set up this lab, you need an Azure subscription and lab account to get started. If you don't have an Azure subscription, create a free account before you begin. Once you get an Azure subscription, you can create a new lab account in Azure Lab Services. For more information about creating a new lab account, see the tutorial on how to setup a lab account. You can also use an existing lab account.

Lab account settings

Enable your lab account settings as described in the following table. For more information about how to enable Azure Marketplace images, see Specify the Azure Marketplace images available to lab creators.

Lab account setting Instructions
Marketplace image Enable 'Visual Studio 2019 Community (latest release) on Windows Server 2019 (x64)' image for use within your lab account.

Lab settings

The size of the virtual machine (VM) that we recommend depends on the types of workloads that your students need to do.

Lab setting Value and description
Virtual Machine Size Medium

We recommend testing your workloads to see if a larger size is needed. For more information about each size, see VM sizing.

Template machine configuration

The steps in this section show how to complete the following to set up the template VM:

  1. Install Development tools.
  2. Install debugger extensions for your web browser.
  3. Update firewall settings.

Install Development tools

The 'Visual Studio 2019 Community (latest release) on Windows Server 2019 (x64)' image already has the required Node.js development workload installed for Visual Studio 2019.

  1. Install your preferred web browser. The image has Internet Explorer installed by default.
  2. Navigate to Node.js website and select the Download button. You can use the latest long-term service (LTS) version, current version with that latest features, or a previous release. Installing NodeJS will also install Node Package Manager, which will be used for installing the React, Redux, and JSX.
  3. Update Visual Studio 2019 to the latest release, if needed.

Other components needed for a React-based website are installed using NPM into a specific application. To add NPM packages, see manage your NPM packages in Visual Studio.

For example, if using the Node.js Interactive Window in a project, enter the following commands to install the React, Redux, and JSX libraries:

.npm install react
.npm install react-dom
.npm install react-redux
.npm install react-jsx

To create your first Node.js with React app in Visual Studio, see Tutorial: Create a Node.js and React app in Visual Studio.

Install debugger extensions

Install the React Developer Tools extensions for your browser so you can inspect React components and record performance information.

Update firewall settings

By default, inbound traffic to your Node.js server will be blocked. If you wish to access a student's website while it's running, add an in-bound firewall rule to allow the traffic. Look at the Application Port project property to see which port will be used during debugging. The example below uses the New-NetFirewallRule PowerShell cmdlet to allow access to port 1337.

New-NetFirewallRule -DisplayName "Allow access to Port 1337" -Direction Inbound -LocalPort 1337 -Protocol TCP -Action Allow

Important

Instructors must use the template VM or another lab VM to access a student's website.

Cost

Let’s cover an example cost estimate for this class. Suppose you have a class of 25 students. Each student has 20 hours of scheduled class time. Another 10 quota hours for homework or assignments outside of scheduled class time is given to each student. The virtual machine size we chose was Medium, which is 55 lab units.

  • 25 students × (20 scheduled hours + 10 quota hours) × 55 Lab Units × USD0.01 per hour = 412.50 USD

Important

The cost estimate is for example purposes only. For current pricing information, see Azure Lab Services pricing.

Next steps

The template image can now be published to the lab. See publish the template VM for further instructions.

As you set up your lab, see the following articles:
