What is a middleware?

What is a middleware? It’s a function that executes before every page request with minimal impact on loading speed while having a powerful impact on your store. Check a user’s origin and adjust content, language, and currency accordingly. Identify a user and track them server-side more accurately than traditional client-side methods. Assign a user a specific version of your page, effective for A/B testing. The applications are virtually limitless, opening up a wide range of possibilities for website optimization and user experience improvement. #middleware #headlesscommerce Middleware Vectors by Vecteezy: https://buff.ly/3I2VoV7
