Working with Visual Studio Code¶
Authored by Oliver Smith (oliver.smith@canonical.com)
The easiest way to access your Ubuntu development environment in WSL is by using Visual Studio Code via the built-in Remote
extension.
What you will learn:¶
How to set up Visual Studio Code for remote development on Ubuntu on WSL
How to start a basic Node.js webserver on Ubuntu using Visual Studio Code
What you will need:¶
A PC with Windows 10 or 11
(Optional) This tutorial uses Windows Terminal Preview, which you can get from the Microsoft Store
Install Ubuntu on WSL2¶
This tutorial assumes that you already have WSL2 installed with the latest LTS release of Ubuntu.
If not, check out our getting started tutorials for Windows 10 and Windows 11:
Once you have completed the relevant tutorial, the following steps will work on either Windows 10 or 11.
Install Visual Studio Code on Windows¶
One of the advantages of WSL is that it can interact with the native Windows version of Visual Studio Code using its remote development extension.
To install Visual Studio Code visit the Microsoft Store and search for Visual Studio Code.
Then click Install.
Alternatively, you can install Visual Studio Code from the web link here.
During installation, under the ‘Additional Tasks’ step, ensure the Add to PATH
option is checked.
Once the installation is complete, open Visual Studio Code.
Install the Remote Development Extension¶
Navigate to the Extensions
menu in the sidebar and search for Remote Development
.
This is an extension pack that allows you to open any folder in a container, remote machine, or in WSL. Alternatively, you can just install Remote - WSL
.
Once installed we can test it out by creating an example local web server with Node.js
Install Node.js and create a new project¶
Open your WSL Ubuntu terminal and ensure everything is up to date by typing:
$ sudo apt update
Then:
$ sudo apt upgrade
Entering your password and pressing Y
when prompted.
Next, install Node.js and npm:
$ sudo apt-get install nodejs
$ sudo apt install npm
Press Y
when prompted.
Now, create a new folder for our server.
$ mkdir serverexample/
Then navigate into it:
$ cd serverexample/
Now, open up your folder in Visual Studio Code, you can do this by typing:
$ code .
The first time you do this, it will trigger a download for the necessary dependencies:
Once complete, your native version of Visual Studio Code will open the folder.
Creating a basic web server¶
In Visual Studio Code, create a new file called package.json
and add the following text (original example)
{
"name": "Demo",
"version": "1.0.0",
"description": "demo project.",
"scripts": {
"lite": "lite-server --port 10001",
"start": "npm run lite"
},
"author": "",
"license": "ISC",
"devDependencies": {
"lite-server": "^1.3.1"
}
}
Save the file and then, in the same folder, create a new one called index.html
Add the following text, then save and close:
<h1>Hello World</h1>
Now return to your Ubuntu terminal (or use the Visual Studio Code terminal window) and type the following to install a server defined by the above specifications detailed in package.json
:
$ npm install
Finally, type the following to launch the web server:
$ npm start
You can now navigate to localhost:10001
in your native Windows web browser by using CTRL+LeftClick
on the terminal links.
That’s it!
By using Ubuntu on WSL you’re able to take advantage of the latest Node.js packages available on Linux as well as the more streamlined command line tools.
Enjoy Ubuntu on WSL!¶
In this tutorial, we’ve shown you how to connect the Windows version of Visual Studio Code to your Ubuntu on WSL filesystem and launch a basic Node.js webserver.
We hope you enjoy using Ubuntu inside WSL. Don’t forget to check out our other tutorials for tips on how to optimise your WSL setup for Data Science.
