The frontend framework debate has shifted. It's no longer React vs Vue vs Angular -- it's React (and its SPA cohort) vs htmx and the hypermedia-driven resurgence. After building production applications with both, here's a practical guide to choosing the right tool.
React is a client-side rendering library. You ship JavaScript, it builds the DOM, manages state, and orchestrates interactions. htmx extends HTML with attributes that let any element make HTTP requests and swap the response into the DOM without writing JavaScript.
React says: "Your server sends JSON, the browser builds the UI." htmx says: "Your server sends HTML, the browser swaps it in."
