Improvements based on PR #8

[coderabbitai]

This issue is based on the changes introduced in PR #8 (dikshant-infracloud#8).

Improvements:

1. Dockerfile:

   • The specific Node.js version tag FROM node:14.17.5 was removed, allowing the Docker image to use the latest available Node.js version.
   • The EXPOSE 3005 line was removed, which may affect how the application is accessed externally, as it no longer explicitly declares the port it listens on.

2. package.json:

   • Two empty lines were added, one at the beginning and one at the end of the file. These are purely formatting changes and do not affect the functionality of the project.

Please review these changes and consider any further improvements or adjustments that may be necessary.
