Winden

Integrations

Winden is a page builder agnostic Tailwind CSS integration for WordPress. It is designed to work with any page builder or theme — no vendor lock-in.

Built-in integration

Winden comes with built-in integration with the following page builders:

And we plan to add more first-class integrations in the future.

WordPress hooks

Winden provides simple WordPress hooks to integrate with your page builder.

f!winden/core/runtime:is_inside_builder

This filter hook is used to determine whether the current page is being edited in a page builder.

Winden will load the CDN when the page is edited in a page builder’s editor, instead of the cached CSS File.

<?php

add_filter('f!winden/core/runtime:is_inside_builder', 'example_is_inside_builder', 10);

/**
 * @param bool $is By default, this is false.
 */
function example_is_inside_builder(bool $is): bool
{
    // Check if the current page is inside the Bricks Builder.
    if (bricks_is_builder()) {
        return true;
    }

    return $is;
}

f!winden/core/runtime:tailwind_config

This filter hook is used to modify the Tailwind CSS configuration before it is used on the CDN and Worker.

<?php

add_filter('f!winden/core/runtime:tailwind_config', 'example_breakpoint_placeholder', 10);

/**
 * [Bricks Builder] Replace the breakpoint placeholder `SYNC_BREAKPOINT` with the actual value.
 */
function example_breakpoint_placeholder(string $config): string
{
    // return $config immediately if $config doesn't contain 'SYNC_BREAKPOINT' placeholder
    if (false === strpos($config, 'SYNC_BREAKPOINT')) {
        return $config;
    }

    $breakpoints = \Bricks\Breakpoints::get_breakpoints();
    $base_width  = \Bricks\Breakpoints::$base_width;

    $theme = [];

    foreach ($breakpoints as $breakpoint) {
        $key = apply_filters('f!winden/builder/bricks/runtime:breakpoint_key', $breakpoint['key']);

        /**
         * Larger than base breakpoint:  use 'min-width'
         * Smaller than base breakpoint: use 'max-width'
         */
        $min_max = $breakpoint['width'] > $base_width ? 'min-width' : 'max-width';

        $raw = ['raw' => sprintf('(%s: %spx)', $min_max, $breakpoint['width'])];

        // Is base breakpoint, but not mobile-frist: Add first
        if (!\Bricks\Breakpoints::$is_mobile_first && (isset($breakpoint['base']) || $breakpoint['width'] > $base_width)) {
            $theme = [$key => $raw] + $theme;
        } else {
            $theme[$key] = $raw;
        }
    }

    return str_replace('SYNC_BREAKPOINT', json_encode($theme, JSON_FORCE_OBJECT), $config);
}

f!winden/core/worker:compile_content_payload

This filter hook is used to modify the HTML content before sending it to the Worker. You can append additional HTML content to the payload.

<?php

add_filter('f!winden/core/worker:compile_content_payload', 'example_gutenberg_append_content_payload', 10);

/**
 * [Gutenberg] Append the rendered Gutenberg content to the payload.
 */
function example_gutenberg_append_content_payload(string $content): string
{
    $posts = [];

    $query = new WP_Query([
        'posts_per_page' => -1,
        'post_type' => [
            'post',
            'page',
            'wp_template',
        ],
    ]);

    foreach ($query->posts as $post) {
        if (!empty(trim($post->post_content))) {
            $post_content = $post->post_content;

            $post_content = do_blocks($post_content);
            $post_content = wptexturize($post_content);
            $post_content = convert_smilies($post_content);
            $post_content = shortcode_unautop($post_content);
            $post_content = wp_filter_content_tags($post_content);
            $post_content = do_shortcode($post_content);

            $posts[] = $post_content;
        }
    }

    $content .= implode("\n", $posts);

    return $content;
}

Render the Tailwind CSS CDN

If you want to render the Tailwind CSS CDN manually, you can use the \Wakaloka\Winden\Plugin::get_instance()->runtime->enqueue_cdn() function to render the CDN.

<?php

add_action('init', 'example_bricks_iframe_render_cdn');

function example_bricks_iframe_render_cdn()
{
    if (bricks_is_builder_iframe()) {
        add_action('wp_head', function() {
            \Wakaloka\Winden\Plugin::get_instance()->runtime->enqueue_cdn();
        }, 1000001);
    }
}
