XShop – Architecture (v1.0.0)
1. Overview
repo/
docs/ # product specs & ADRs
xshop-theme/ # presentation layer
xshop-core/ # companion plugin
release/ # built zips (not committed)
tools/ # build / QA scripts
Two installable artifacts: theme (xshop) + plugin (xshop-core). Theme never stores business logic that outlives theme activation (wishlist/compare/Q&A/banners live in plugin).
2. Theme – xshop-theme
2.1 File map (M1)

2.2 Bootstrap
functions.php is a thin loader:
require_once __DIR__ . '/inc/setup/theme-support.php';
require_once __DIR__ . '/inc/setup/menus.php';
// ... each file exposes a single setup function hooked appropriately
No giant functions.php. Each inc/* file is namespaced or prefixed xshop_.
2.3 Namespacing & Prefixing
- Text domain:
xshop - PHP functions/options/actions/meta:
xshop_prefix. - Classes:
XShop\Theme\...andXShop\Core\...(PSR-4 style even if manual require).
2.4 Hook Strategy
- Use
after_setup_themefor theme support,initfor CPT/taxonomy (only banners/Q&A). - Use
wp_enqueue_scriptswith conditional loading. - Use WC hooks for pricing, badges, loops – avoid overriding templates unless necessary.
3. Plugin – xshop-core

templates/ # wishlist, compare, banners front-end fragments
Plugin owns persistence for wishlist/compare/Q&A/banners. Theme only renders.
4. Data Ownership
- WC: products, variations, orders, customers, coupons, shipping, payment, taxes, cart, checkout.
- WP: users, posts, pages, media, menus, comments.
- Custom: banners (CPT
xshop_banner), Q&A (CPT or comments extension – see DATABASE-MODEL.md), wishlist/compare (user meta + cookie + transient for guests), theme settings (single optionxshop_settings+ mods).
Avoid custom tables in v1; revisit via ADR if scale demands.
5. Design System (M1)
CSS custom properties in assets/css/tokens.css — full token set: primary/secondary/bg/surface/card/text/muted/border/input/focus/link/success/warning/danger (+ bg variants), typography (xs–4xl, weights 400/500/700, leading tight/normal/relaxed), spacing (1–16), container/narrow, radius (sm/md/lg/full), shadow (sm/md/lg), z, transition (fast/normal/slow). Dark mode semantic swap on [data-theme="dark"]. Layering: tokens→base→layout→components→utilities→style.css via inc/setup/assets.php:1.
Logical properties (margin-inline, padding-inline, inset-inline, inset-block, inline-size) throughout; zero left/right in theme CSS. Components consume tokens, never hardcode colours.
6. Asset Strategy (M1)
- No jQuery for new code (vanilla JS;
theme.js:1is deferred). WC jQuery remains for its handlers. - Enqueue:
tokens→base→layout→components→utilities→style.csschain ininc/setup/assets.php:1with versionXSHOP_VERSION;style.cssdeclaresrtlreplace. WC styles dequeued (woocommerce_enqueue_styles→__return_empty_array) to avoid duplication — theme provides compat incomponents.css:1. - Conditional: feature modules (search/filter/wishlist) will be enqueued per-template in M5; M1 only loads
theme.js. - Localized
xshopData(restUrl, nonce, isRtl, i18n) onxshophandle. - Build: no build step required to activate; release minify via
tools/build-release.ps1.
7. AJAX / REST
Prefer WP REST API for search/filter/Q&A (cacheable, nonce via X-WP-Nonce), fallback to admin-ajax for cart/mini-cart where WC expects it. All endpoints: sanitize → validate → capability check → nonce → escaped output.
8. Security Model
See SECURITY.md. TL;DR: sanitize in, escape out, nonces, capability checks, prepared statements, no unserialize, no open redirects.
9. Performance Model
See PERFORMANCE.md. Conditional assets, lazy-load, transients for expensive queries, no N+1, wp_cache.
10. i18n / RTL
- All strings via
__(),_e(),esc_html__()with text domainxshop. - Logical CSS,
dirattribute toggling,is_rtl()branching only where logical props insufficient. - Persian typography tokens,
lang="fa"support, mixed LTR numbers handled viaunicode-bidiwhere needed.
11. Templating (M1)
header.php:1 renders site-header.php:1 + breadcrumbs:1 (except front/404); footer.php:1 renders site-footer.php:1. All content templates (index.php:1, front-page.php:1, single.php:1, page.php:1, archive.php:1, search.php:1, 404.php:1) use Loop + get_template_part() + comments_template() / dynamic_sidebar() where appropriate. Reusable components: breadcrumbs, pagination, search-form, post-card, empty-state, loading, section-heading, hero, promo-banner. No markup duplication. front-page.php:1 is section-based (hero, category grid, product grid via wc_get_products, promo, latest posts) — extensible via xshop_front_hero_args filter.
WC overrides: none in M1; wrappers via woocommerce_before_main_content/after_main_content in inc/woocommerce/setup.php:1. Future overrides documented in docs/woocommerce.md with version map.
12. Decision Records
ADRs in docs/ADR/ – one per major decision (e.g., “No custom tables for Q&A in v1”).
13. Release
release/xshop.zip + release/xshop-core.zip built via tools/build-release.ps1. Excludes .git, node_modules, .env, logs, temp.
14. Versioning
SemVer 1.0.0. CHANGELOG.md follows Keep a Changelog.
15. Risks & Mitigations
- WC API churn → pin tested versions, monitor template versions, use hooks not overrides.
- RTL regressions → logical props + visual regression checklist.
- Demo import timeouts → chunked importer with resume.
