POS UI Optimization

This Odoo 19 module optimizes the Point of Sale (POS) user interface for low-RAM devices (e.g., Android tablets with 2GB RAM).

Features

  • Product List Incremental Loading: Renders products in batches of 40 as you scroll, significantly reducing memory usage in categories with many products.
  • Order Cart Incremental Loading: Efficiently handles large orders by rendering order lines incrementally as you scroll through the cart.
  • Improved Responsiveness: Keeps the browser DOM light and prevents "white blank" screens caused by memory exhaustion.
  • Legacy Browser Support: Designed without modern ES2020 JavaScript syntax (like optional chaining ?.) to ensure compatibility with older Android browser engines found on specific legacy POS hardware.

Installation

  1. Place the pos_ui_optimization folder in your Odoo custom addons directory.
  2. Restart your Odoo server.
  3. In Odoo, activate Developer Mode.
  4. Go to Apps -> Update Apps List.
  5. Search for POS UI Optimization.
  6. Click Install.

Technical Details

This module uses Odoo's JavaScript patching mechanism (patch from @web/core/utils/patch) to extend the core POS components:

  • ProductScreen: Adds displayedProductsCount state via owl's useEffect and an overridden onScroll hook to the product container.
  • OrderDisplay: Adds displayedCount state and a scroll listener to the combo sorted order lines container.

No core Odoo files are modified.
