JAVAPRO · JAVASCRIPT PERFORMANCE FOR PRESTASHOP

Give important JavaScript
a head start.

Your first screen sets the tone for the visit. JavaPro helps the browser discover important storefront scripts sooner, bringing modern preload controls to PrestaShop without editing your theme templates.

HELP THE BROWSER START SOONER

Preload the scripts that matter.

Give selected JavaScript files an early browser hint, so fetching can begin sooner in the page-loading process.

03Support a faster first screen

CONFIDENCE BEFORE PUBLIC RELEASE

Start privately. Go live when ready.

JavaPro installs in Stealth Mode, limiting its loading changes to the admin IP so you can review your storefront before enabling them for shoppers.

  • Manage loading from module configuration.
  • Review your shop with its existing theme and modules.
  • Enable the changes for visitors when ready.

MODERN LOADING. PRACTICAL CONTROL.

Focus on what shoppers see first.

01

JavaScript discovery

Identify the front-office JavaScript files your shop uses as the starting point for managing their loading behavior.

02

Selected script preloads

Help browsers discover important scripts earlier with preload hints for the JavaScript files you select.

03

First-screen focus

Address resource-loading delays that can hold back the first visible part of your shop and its initial impression.

04

Async & defer controls

Advanced loading options give experienced administrators more control over how suitable scripts are loaded and executed.

05

No theme-template edits

Configure JavaScript loading in the module, with no theme-specific template editing required.

06

Private admin-IP review

Use install-time Stealth Mode to review storefront behavior before making the loading changes public.

BUILT AROUND YOUR EXISTING SHOP

Keep your theme. Keep your modules.

JavaPro is designed around standard PrestaShop front-office asset loading, with support for the themes, modules and multishop environments merchants use.

PrestaShop 1.7, 8 & 9

Choose the package for your shop’s PrestaShop version.

Theme & module support

Improve loading behavior while continuing to use your existing storefront and modules.

Multishop compatible

Built to support merchants and agencies working with PrestaShop multishop environments.

PRELOAD, IN PLAIN ENGLISH

Tell the browser what it will need.

A preload hint points the browser toward a resource earlier. JavaPro uses this approach for selected JavaScript files, helping them get discovered and fetched sooner.

Async and defer are separate loading controls for suitable scripts. JavaPro brings these options together in its configuration.

SEE THE FIRST SCREEN TAKE SHAPE

Measure the experience your shoppers get.

Use a WebPageTest filmstrip to compare how the visible page builds before and after your changes. Chrome DevTools can show when script requests begin.

Keep the focus on useful content appearing and the storefront working smoothly, alongside your wider Core Web Vitals work.

BUILT FROM REAL PRESTASHOP PERFORMANCE WORK

Fred tests so you don’t have to start from scratch.

JavaPro comes from hands-on work with production shops: themes, modules, sliders, carts, checkout and tracking scripts. Practical loading controls and private review are built into the workflow.

01 / INSTALL

Begin in Stealth Mode.

Start with loading changes visible to the admin IP.

02 / REVIEW

See it on your storefront.

Review your configuration and the shopping experience privately.

03 / ENABLE

Make it available to shoppers.

Switch from private review to public use when ready.

GIVE YOUR FIRST SCREEN SOME ATTENTION
