How can I implement HMAC Hash-based Message Authentication Code to verify the integrity of sensitive messages in Node js

Question

I need to ensure the integrity and authenticity of sensitive messages in my Node.js application by using HMAC. I understand HMAC can add a layer of security to messages, but I’m not sure how to set it up correctly in Node.

Could someone provide an example of implementing HMAC in Node.js, especially focusing on choosing a secure hashing algorithm and key management? Any best practices would be helpful.
