CodePlayground

CodePlayground is a web-based multi-language code execution service that allows users to submit code in various programming languages (Python, JavaScript, Bash, Java, C, C++) and receive output in real-time. The backend is built using Go and leverages the Docker SDK and system compilers for handling different programming languages.

Features

• Supports multiple programming languages: Python, JavaScript, Bash, Java, C, and C++.
• Compilation and Execution: For compiled languages like C, C++, and Java, the service compiles the submitted code and runs the resulting binary.
• Security through isolation: Future support for Docker containerization to safely isolate code execution.
• REST API: Submit code via a simple HTTP POST request and receive the output.

Languages Supported

• Python
• JavaScript (Node.js)
• Bash
• Java
• C (compiled using gcc)
• C++ (compiled using g++)
