Setting Up pdoTools for MODX Optimization

pdoTools is a set of snippets and tools for MODX, replacing standard Wayfinder, getResources, Breadcrumbs with more performant alternatives. Uses PDO directly, without xPDO ORM overhead.

Installation

Package Manager → pdoTools → install. Includes: pdoResources, pdoMenu, pdoPage, pdoCrumbs, pdoNeighbors, pdoSitemap, pdoField, pdoParser.

pdoResources Instead of getResources

Standard getResources: 30–50 DB queries for 20 resources. pdoResources: 1–3 queries.

[[pdoResources?
    &parents=`5`
    &resources=`-10`
    &showHidden=`0`
    &sortby=`menuindex`
    &sortdir=`ASC`
    &limit=`10`
    &includeTVs=`product_price,product_image`
    &prepareTVs=`1`
    &processTVs=`1`
    &tpl=`productCard`
    &tvPrefix=``
]]

&prepareTVs=1—loads TVs with single JOIN query instead of N separate queries.

pdoPage for Pagination

[[!pdoPage?
    &element=`pdoResources`
    &parents=`5`
    &limit=`12`
    &tpl=`productCard`
    &includeTVs=`product_price,product_image`
    &pageNavVar=`page.nav`
]]
[[!+page.nav]]

pdoPage auto-generates pagination navigation and handles GET parameter page.

pdoMenu Optimization

[[pdoMenu?
    &startId=`0`
    &level=`2`
    &sortby=`menuindex`
    &hideSubMenus=`0`
    &tplOuter=`@INLINE <ul class="nav">[[+wrapper]]</ul>`
    &tpl=`@INLINE <li class="[[+classes]]"><a href="[[+link]]" [[+attributes]]>[[+menutitle]]</a>[[+wrapper]]</li>`
    &tplInner=`@INLINE <ul class="nav__sub">[[+wrapper]]</ul>`
    &hereClass=`active`
    &parentClass=`has-children`
    &cache=`1`
    &cacheTime=`3600`
]]

&cache=1—cache menu for 1 hour. Menu is one of heaviest queries, caching critical.

pdoParser: Fast Parser

pdoParser replaces standard MODX parser. 20–40% faster with many tags per page.

// Enable in system settings:
// System → Settings → pdotools_parser_enable = 1

pdoTools Cache

[[pdoResources?
    ...
    &cache=`1`
    &cacheTime=`1800`
    &cacheKey=`catalog_[[+GET.page:default=1]]_[[+GET.sort:default=price]]`
]]

Unique cache key includes GET filter parameters—different filters = different cache.

Timeline

Replacing standard snippets with pdoTools and setting up caching—3–5 hours for medium site.
