$ git clone [email protected]:app-generator/sample-flask-htmlx.git 
// OR via HTTPS
$ git clone https://github.com/app-generator/sample-flask-htmlx.git

$ source env/bin/activate
$
$ # Virtualenv modules installation (Windows based systems)
$ # virtualenv env
$ # .\env\Scripts\activate

👉 Step 3 - Install Dependencies

$ pip3 install -r requirements.txt

👉 Step 4 - Create Database

$ flask shell    # launch Flask Shell
>>> 
>>> from app import db
>>> db.create_all()

👉 Step 4 - Create Database

$ flask run

👉 Step 5 - Start the APP

$ flask run

The app should be up & running on address http://localhost:5000

All forms managed by the app use HTMLx directives. Here is the Login Form Source Code and used HTMLx directives:

• hx-swap
• hx-post
• hx-target

    <form  hx-swap="outerHTML" 
           hx-post="{{ url_for('auth.signin') }}" 
           hx-push-url="true" 
           hx-target=".content" 
           class="p-5 bg-white shadow mh-100 col-sm-8 col-md-6 col-lg-4" novalidate >
        
        <p class="h3 text-center p-2">SignIn</p>
        
        <!-- Truncated content -->

        <div class="form-input p-1">
            {{form.email.label}}
            {{form.email(class_="form-control")}}
        </div>

        <div class="form-input p-1">
