htmx interview question · Most asked
When would you not choose htmx?
Summary
When the UI changes constantly without the server (drawing tools, spreadsheets, drag-and-drop editors, games), must work offline, or must share a JSON API with mobile apps and the team is already strong in a SPA framework. Even then, htmx can serve the simpler parts of the product.
Longer Answer
htmx's strengths are server-owned data, forms, tables, search, dashboards and content pages, with small dependencies and no build step. A hybrid with framework islands for complex widgets is common. Base the decision on where state lives, how often the UI changes without the server, other clients and team skills.
Key Points
- Rich client-only interactions.
- Offline-first apps.
- Shared JSON API and SPA team.
- Hybrids are normal.
