Implement task #20 - Javascript logger

[brian-ai-assistant[bot]]

Architecture

To implement the logger functionality in a secure manner, I would propose the following architecture:

1. Frontend:

   • The frontend will be built using HTML, CSS, and JavaScript.
   • The logger will be a JavaScript module that can be included in any web page.
   • The logger will provide methods for logging different levels of messages: error, debug, info, and warn.
   • Initially, the logger will use the console transport for logging.

2. Backend:

   • The backend will be built using a server-side technology, such as Node.js.
   • The backend will provide an API endpoint to receive log messages from the frontend.
   • The log messages will be stored securely in a file on the server.

3. Security considerations:

   • The API endpoint should be protected with appropriate authentication and authorization mechanisms to ensure that only authorized users can log messages.
   • The log file should be stored in a secure location on the server and should be protected from unauthorized access.
   • The logger module should perform input validation and sanitize the log messages to prevent any potential security vulnerabilities.

Code

Based on the above architecture, I would create the following files:

1. index.html - The HTML file for the frontend.
2. styles.css - The CSS file for the frontend.
3. logger.js - The JavaScript module for the logger.
4. server.js - The backend server code.

Please find the content of each file below.
