How to setup a dev environment with:

Repo structure

├── .devcontainer.backup -> If you follow the tutorial, but it's not working you can use this working devcontainer to
├── src -> It contains a testing code written in node.js

Setting up the devcontainer

Ensure you have Docker, VSCode, and Dev Containers extension installed.

Open the command palette and click Add Dev Container Configuration Files. This will start a wizard to create your devcontainer.json file.

Select add configuration to workspace. This will create the devcontainer.json inside your project allowing you to commit and share with others.

Now you need to choose the base image that your container will run. Here we will select Node.js & JavaScript.

Choose the node version that you want to use. Here we will keep the default one.

Done! Now you should have a .devcontainer folder in your project.

Now you can start your container. You can open the Command Palette and click on Reopen in Container

After a few moments, your container will be available and ready to use. Now you can start programming, to test this you can run the following commands

cd src
node main.js
