Learning Code Editor API

This project is an API designed to execute code dynamically in multiple programming languages. Supported languages include C#, JavaScript, Python, Java, C, and C++. The API receives code from a frontend application (e.g., React) and returns the output or any errors.

Technologies Used

• ASP.NET Core: Framework to build the API.
• Microsoft.CodeAnalysis.CSharp.Scripting (Roslyn): To execute C# code.
• Jint: JavaScript engine for .NET.
• Python: Executed as an external process.
• Java (JDK): Executed as an external process.
• GCC/G++: Compiler to execute C and C++ code.

Prerequisites

General

• .NET SDK 8.0 or higher
• Git (to clone the repository)

System Dependencies

• Python: Install Python and ensure it is added to the PATH.
• Java (JDK): Install the JDK and ensure both javac and java are in the PATH.
• GCC/G++: Install MinGW on Windows, or use GCC on Linux/Mac and add gcc and g++ to the PATH.

.NET Dependencies

Run the following command in the project root to install the required .NET dependencies:

dotnet add package Microsoft.CodeAnalysis.CSharp.Scripting
dotnet add package Jint
