    # Install this plugin
    npm install @pinelab/vendure-plugin-limited-products

Set a max quantity or bulk quantity per product

This plugin allows you to:

  1. Limit the amount of a specific product per order. I.E. A customer is only allowed to buy 1 of product "Limited art t-shirt X" per order.
  2. Only allow a product to be purchased in multiples of X. E.g. only per 4 items.

Getting started

  1. Add the following config to your vendure-config.ts:
import { LimitedProductsPlugin } from "@pinelab/vendure-plugin-limited-products"

plugins: [
   LimitedProductsPlugin,
   AdminUiPlugin.init({
    port: 3002,
    route: 'admin',
    app: compileUiExtensions({
      outputPath: path.join(__dirname, '__admin-ui'),
      extensions: [
         // Include the admin UI extensions of this plugin
         LimitedProductsPlugin.uiExtensions
      ],
   }),
];
  1. Run a database migration to add the custom fields.
  2. Start Vendure, login and go to the product you want to limit.
  3. Set the custom field Maximum amount per order and Multiple of per order on a variant and update the product
  4. Customers can now only buy X amount of the variant per order. The same customer can still order the product again in a new order.

You can fetch product.limitPurchasePerMultipleOf and product.maxQuantityPerOrder via the Shop API to display messages on your storefront accordingly.

Migrating to V3.x

V3 removes the fields from the variant and places them on a Product, in a different format. This plugin isn't used much, so there is no migration script available. We do it manually:

  1. Back up all values of the variants before installing the plugin.
  2. Install V4 of this plugin, and run a database migration.
  3. Start the server and set the values on the parent products via the Admin UI
