The URL router makes it easy to give every page a clean URL.

// PHP
/blog/posts.php?postId=1234

// THT
/blog/posts/1234/my-favorite-things

Template functions let you cleanly organize your view-level code in a way that is both flexible and fast.

Templates support HTML-C shortcuts, and automatically escape variables to prevent XSS attacks.

// PHP
function messagesHtml($messages) { ?>
    <div class="messages">
    <?php foreach ($messages as $m) { ?>
        <div class="message"><?= $m['subject'] ?></div>
    <?php } ?>
    </div>
<?php }

// THT
tem messagesHtml($messages) {

    <.messages>
    --- foreach $messages as $m {
        <.message> {{ $m.subject }}
    --- }
    </>
}

THT validates all user input by default, including secure file uploads.

// PHP - No validation  (✖ Unsafe)
$userId = $_GET['userId'];

// THT - Validate as a positive (i)nteger
$userId = Input.get('userId', 'i')

The Form module makes it easier to build mobile-friendly forms. Input fields are validated on both the client (for usability) and the server (for security).

The Session module is built with secure defaults and has methods for common tasks like setting fire-and-forget flash data.

$cartKey = 'shoppingCart'

Session.addToList($cartKey, 'T-Shirt')
Session.addToList($cartKey, 'Teddy Bear')

Session.get($cartKey)
//= ['T-Shirt', 'Teddy Bear']

The Database module has convenience methods for CRUD operations.

It uses SQL TypeStrings to prevent injection attacks.

$query = sql'select * from posts where userId = {}'
$query.fill(123)

Db.selectRows($query)

The Email module makes it easy to send email (HTML or plaintext) through a third-party email sender.

Email.send({
    from: 'you@yoursite.com'
    to: 'user@mail.com'
    subject: 'Welcome!'
    body: '''
        Thanks for joining!
    '''
})

THT comes with an optional lightweight CSS framework with reset styles, a responsive grid system, and SVG icons.

THT introduces Litemark, a Markdown variant that supports different authoring modes (e.g. user comments vs documentation) and the creation of custom tags.

# Heading
