Very Nice and simple set up. I bumped into it while looking for HTMX resources.So I will look very closely to your other post about HTMX. In your blog post I noticed two small typos in your routes.py. @app.route('/welcome') def hello(): name = 'AJ' return render_template("index.html", value=name) The default route is simply @app.route('/') and the rendering should be name=name rather than value=name. Again Thanks for your post !!
