LabEx VM WebIDE Interface

Working with Java projects in WebIDE:

1. Create a new Java file via the explorer
2. Write your Java code with syntax highlighting
3. Compile and run in the terminal:

javac MyClass.java
java MyClass

4. View compilation errors and warnings in real-time

For frontend development tasks:

1. Create HTML, CSS, and JavaScript files
2. Click the “Go Live” button in the bottom right corner
3. Access your web page through:
   • Web 8080 tab at the top of the LabEx VM
   • Create new port preview tabs using the + button

Note: Your project is automatically deployed to a public URL on the LabEx server, making it accessible through the Web tabs.

For Python programming:

1. Create a Python file in the explorer
2. Write your Python code with:
   • Syntax highlighting
   • Code completion
   • Error detection
3. Run your script in the terminal:

python3 script.py

4. Use the integrated debugger for step-by-step execution

LabEx VM automatically deploys your web projects:

1. Default port 8080:

   • Click the “Web 8080” tab at the top of the LabEx VM
   • Your application will be accessible through a public URL

2. Custom ports:

   • Click the + button to create new port preview tabs
   • Each port gets its own public URL
   • Useful for running multiple services (e.g., frontend and backend)

Note: Unlike local development, you don’t access localhost directly as LabEx runs in the cloud.

pip install package-name

Remember that installations are temporary and will be reset when your session ends.

The WebIDE provides several ways to manage files:

1. Upload Files:

   • Drag and drop files into the explorer
   • Use the upload/download after right-clicking in the explorer

2. Download Files:

   • Binary files should use the upload/download features

Remember that all files are temporary and will be lost when your session ends.
