What is Supervisor?
Supervisor is a tool that automatically restarts Node.js scripts when they crash or any `*.js` files are modified. This ensures continuous operation and immediate updates without manual intervention, making development more efficient.
Key differentiator
“Supervisor stands out by providing a simple and effective way to automatically manage Node.js scripts without the need for complex configurations or additional tools.”

Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Supervisor is primarily designed for Node.js scripts and lacks native support for other languages, limiting its utility in polyglot environments.
Continuous monitoring of `*.js` files can introduce performance overhead, especially in large projects with many files, potentially slowing down the development workflow.
Setting up Supervisor for complex project structures or custom behaviors requires a deep understanding of its configuration options and can be error-prone.
The official documentation is limited, making it difficult to troubleshoot issues or understand advanced features without referring to community forums or trial-and-error approaches.
