Javascript Fatigue: HTMX Is All You Need to Build ChatGPT

SMRTR summary

This tutorial demonstrates building a streaming ChatGPT-like application using HTMX instead of JavaScript, upgrading from synchronous to asynchronous communication. The implementation uses Server-Sent Events (SSE) for real-time streaming, asyncio queues for managing multiple user sessions, and integrates Google's Agent Development Kit to create a search-powered chatbot. The final result delivers a fully functional chat interface with under 200 lines of code, proving web applications can be built without heavy JavaScript frameworks.
