# GraalVM Java to JavaScript Polyglot Debugging
# Debugging a Java with JavaScript Embedding Application

This sample code helps to demonstrate simplicity of debugging and developing GraalVM Polyglot applications using __VS Code extensions__.
This sample code helps to demonstrate simplicity of debugging and developing GraalVM polyglot applications using Visual Studio (VS) Code extensions.

## Prerequisites

1. VS Code has to be installed.
1. Install VS Code and launch it.
2. Then go to VS Code Extensions activity panel and search for _GraalVM Extension Pack_, install it. The GraalVM Extension Pack will install all required extensions.
3. [Install GraalVM in VS Code](https://www.graalvm.org/latest/tools/vscode/graalvm-extension/#graalvm-installation-wizard): Navigate to Gr activity panel in VS Code and install some of the latest GraalVM __Enterprise Edition__ versions available from the list.
2. Open Visual Studio Code, navigate to Extensions activity panel in the left-hand side Activity Bar. Search for “GraalVM” in the search field. Find [GraalVM Tools for Java](https://marketplace.visualstudio.com/items?itemName=oracle-labs-graalvm.graalvm), press Install. Reload will be required.
3. [Install GraalVM in VS Code](https://www.graalvm.org/latest/tools/vscode/graalvm-extension/#graalvm-installation-wizard): Navigate to Gr activity panel in VS Code and install the latest Oracle GraalVM version available from the list.
4. Confirm to set this as _Active GraalVM_ for VS Code.
5. Install the `js` component.

## Debugging the project

Working with Polyglot project in VSCode is simple just open this sample.
## Build and Run the Application

1. Open VS Code Terminal.
2. Clone the repository and navigate into the `polyglot-debug` directory:
```bash
git clone https://github.com/graalvm/graalvm-demos
```
```bash
cd graalvm-demos/polyglot-debug
```

3. Build the application using Maven:
```bash
mvn clean package
```
4. Run this application with the following command:
```bash
mvn exec:exec
```

## Debug the Application

Working with a polyglot project in VS Code is simple just open this sample.
It will be working out of the box with VS Code GraalVM extensions.

Place breakpoints either in Java or JavaScript code.
1. Place breakpoints either in Java or JavaScript code.

2. To debug the project, go to __Run and Debug__ activity or simply press F5.

To debug the project go to __Run and Debug__ activity or simply press F5.
Choose **Launch Java 8+** as this is the Polyglot debugger provided by GraalVM extensions.
3. Choose **Launch Java 8+** as this is the Polyglot debugger provided by the GraalVM extension.

That is, the sample is running under debugger on GraalVM.
