# Try Out Development Containers: Node.js

This is a sample project to go along with the "Try a dev container" quick start for the **[VS Code Remote - Containers](https://aka.ms/vscode-remote/containers)** extension.

**If you are not yet in a development container, [see below](#setting-up-the-development-container).**

## Things to try

One you have this sample opened in a container, you'll be able to work with it like you would locally.

Some things to try:

1. **Edit:**
   - Open `server.js`
   - Try adding some code and check out the language features. Notice that `eslint` and the `vscode-eslint` extension are already installed in the container.
2. **Terminal:** Press <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>\`</kbd> and type `uname` and other Linux commands from the terminal window.
3. **Build, Run, and Debug:**
   - Open `server.js`
   - Add a breakpoint (e.g. on line 20).
   - Press <kbd>F5</kbd> to launch the app in the container.
   - Once the breakpoint is hit, try hovering over variables, examining locals, and more.
   - Continue, then open a local browser and go to `http://localhost:3000` and note you can connect to the server in the container.
4. **Forward another port:**
   - Stop debugging and remove the breakpoint.
   - Open `server.js`
   - Change the server port to 5000. (`const PORT = 5000;`)
   - Press <kbd>F5</kbd> to launch the app in the container.
   - Press <kbd>F1</kbd> and run the **Remote-Containers: Forward Port...** command.
   - Select port 5000.
   - Click "Open Browser" in the notification that appears to access the web app on this new port.

2. If you're not yet in a development container:
   - Clone this repository.
   - Press <kbd>F1</kbd> and select the **Remote-Container: Open Folder in Container...** command.
