About

The vendure-bulk-discounts plugin allows you to define different prices for product variants depending on the amount being purchased by clients. Right now prices aren't reduced! This plugin is mainly a preparation for when promotion actions have access to the database.

Disclaimers

• I haven't worked with angular a lot, I'm sorry if some of my angular code looks more like react. Feel free to tell me what should be done differently.
• There are no tests yet!

  productVariant: ProductVariant!
  quantity: Int!
  price: Int!
}

input BulkDiscountInput {
  quantity: Int!
  price: Int!
}

extend type Query {
  productBulkDiscounts(productId: ID!): [BulkDiscount!]!
}

extend type Mutation {
  updateProductVariantBulkDiscounts(
    productVariantId: ID!
    discounts: [BulkDiscountInput!]!
  ): Boolean!
  updateProductVariantBulkDiscountsBySku(
    productVariantSku: String!
    discounts: [BulkDiscountInput!]!
  ): Boolean!
}
extend type ProductVariant {
  bulkDiscounts: [BulkDiscount!]!
}

Shop

type BulkDiscount {
  productVariant: ProductVariant!

Known issues

• Right now this plugin only stores data, the ability to access the DB in promotion actions is in development.

Code

• The integration in the admin ui is a little hacky, especially the retrieval of the product and variant id/sku

UI

• Currently one is required to manually press the save button in addition to the save button for the product
