We are excited to announce the release of Vendure v0.17.0! This release introduces improved stock control capabilities, custom permissions, and more!

Improved stock control

This release put you in control of how you manage your stock. First let’s define a few new concepts:

  • Stock on hand: This refers to the number of physical units of a particular variant which you have in stock right now. This can be zero or more, but not negative.
  • Allocated: This refers to the number of units which have been assigned to Orders, but which have not yet been fulfilled.
  • Out-of-stock threshold: This value determines the stock level at which the variant is considered “out of stock”. This value is set globally, but can be overridden for specific variants. It defaults to 0.
  • Saleable: This means the number of units that can be sold right now. The formula is: saleable = stockOnHand - allocated - outOfStockThreshold

Here’s a table to better illustrate the relationship between these concepts:

Stock on hand Allocated Out-of-stock threshold Saleable
10 0 0 10
10 0 3 7
10 5 0 5
10 5 3 2
10 10 0 0
10 10 -5 5

The saleable value is what determines whether the customer is able to add a variant to an order. If there is 0 saleable stock, then any attempt to add to the order will result in a new InsufficientStockError.

Back orders

You may have noticed that the outOfStockThreshold value can be set to a negative number. This allows you to sell variants even when you don’t physically have them in stock. This is known as “back orders”.

Back orders can be really useful to allow orders to keep flowing even when stockOnHand temporarily drops to zero. For many businesses with predictable re-supply schedules they make a lot of sense.

Once a customer completes checkout, those variants in the order are marked as allocated. When a Fulfillment is created, those allocations are converted to Sales and the stockOnHand of each variant is adjusted. Fulfillments may only be created if there is sufficient stock on hand.

Configurable stock allocation

By default, stock is allocated when checkout completes, which means when the Order transitions to the 'PaymentAuthorized' or 'PaymentSettled' state. However, you may have special requirements which mean you wish to allocate stock earlier or later in the order process. With the new StockAllocationStrategy you can tailor allocation to your exact needs.

Custom permissions

Vendure has a powerful role-based access control system built in. However, up until now it has been impossible to define your own custom permissions. This release adds support for easily defining custom permissions and using them to secure your own GraphQL & REST operations & end-points. These permissions can then be used in creating Roles, giving you total control over exactly which users may make use of the capabilities defined by your plugins.

For an example of how simple it is to define new permissions, see the new Defining Custom Permissions guide.

What’s more, your custom permissions will automatically appear in the Admin UI Roles editor, allowing seamless management of your plugin permissions!

Tax improvements

Tax can be a confusing subject. Our own tax handling was also a little confusing too - but this release aims to improve the situation!

Consistent OrderItem.unitPrice

The GraphQL OrderItem.unitPrice field used to be given with or without taxes included, depending on the Channel settings. Now it is always the pre-tax price, and the unitPriceWithTax field is always the tax-included price.

Note: To convert existing Orders, you’ll need to add a custom query to your database migration - see the migration guide below.

More detailed tax information

There are also a couple of new fields which give more information about taxes applied to an Order:

  • The OrderLine GraphQL type now includes new tax-related fields:
    • linePrice The total price of the line excluding tax
    • linePriceWithTax The total price of the line including tax
    • lineTax The total tax on this line
    • taxRate The percentage rate of tax applied to this line
  • The Order GraphQL type now includes a taxSummary field which provides a breakdown of how much tax is being charged at each applicable tax rate, which looks like this:
      "data": {
        "activeOrder": {
          "code": "WFJQG3YL1XVPHZCG",
          "totalBeforeTax": 8188,
          "total": 9756,
          "taxSummary": [
              "taxRate": 20,
              "taxBase": 7489,
              "taxTotal": 1498
              "taxRate": 10,
              "taxBase": 699,
              "taxTotal": 70

List filter improvements

List queries in the GraphQL APIs can now be filtered with the new in and regex filter.

The in filter allows filtering by matching the field against one of the provided strings:

query {
  orders(options: {
    filter: {
      state: {
        in: ["PaymentAuthorized", "PaymentSettled"]
  }) {
    items {
      # ...etc

The regex filter allows matching the field against a regular expression:

query {
  customers(options: {
    filter: {
      emailAddress: {
        regex: "g(oogle)?mail\\.com$"
  }) {
    items {
      # ...etc

Note: the specific supported regex syntax varies between the different database drivers.

These new filters enabled a much improved list view for orders in the Admin UI:

Other notable improvements

  • The ShippingMethod entity is now translatable, and now features both name and description fields, allowing richer information to be provided to customers.
  • All methods of configurable strategies (e.g. PaymentMethodHandler, ShippingCalculator etc.) now receive the RequestContext object.
  • The Fulfillment entity now supports custom fields.
  • Performance of ShippingEligibilityCheckers has been drastically improved. Previously every checker was executed on every change to an Order. This could have resulted in hundreds of needless calls. For async checkers, especially those which call out to third-party APIs, this lead to poor performance. Now only the checker of the selected ShippingMethod is ever called, and even those calls can be minimized using the new ShouldRunCheck function.

BREAKING CHANGES / Migration Guide

🚧 Read this section carefully

👉 For general instructions on upgrading, please see the new Updating Vendure guide.

Database migration

Note: The SQL syntax given here is for MySQL. If you are using Postgres, adjust the syntax accordingly, i.e. double-quotes for tables/column names, single-quote for string literals etc.

  1. Generate a migration script as described in the Migrations guide.
  2. If you are using MySQL or MariaDB, you’ll need to disable foreign key checks for the migration, due to an open TypeORM issue:
    public async up(queryRunner: QueryRunner): Promise<any> {
      await queryRunner.query("SET FOREIGN_KEY_CHECKS=0;", undefined);
      // ... the generated migration statements
      await queryRunner.query("SET FOREIGN_KEY_CHECKS=1;", undefined);
  3. Add the following line immediately before the first generated migration query:
    // Migrate existing OrderItems to use the new tax convention
    await queryRunner.query("UPDATE `order_item` SET `unitPrice` = ROUND(`unitPrice` / ((`taxRate` + 100) / 100)) WHERE `unitPriceIncludesTax` = 1", undefined);
  4. Add the following line immediately after the CREATE TABLE shipping_method_translation statement:
    // Migrate existing ShippingMethod names to the new translatable schema structure
    await queryRunner.query("INSERT INTO `shipping_method_translation` (`languageCode`, `name`, `description`, `baseId`) SELECT 'en', `description`, '', id FROM `shipping_method`", undefined);
  5. IMPORTANT test the migration first on data you are prepared to lose to ensure that it works as expected. Do not run on production data without testing. For production data, make a full backup first!

Adding RequestContext

If you have created your own custom strategies, you’ll need to add the RequestContext argument as the first argument in any methods. TypeScript will tell you about this when you try to compile. For example:

export const myShippingCalculator = new ShippingCalculator({
    code: 'my-shipping-calculator',
    description: [/* */],
    args: {},
-    calculate: (order, args) => {
+    calculate: (ctx, order, args) => {
        return { price: args.rate, priceWithTax: args.rate * ((100 + args.taxRate) / 100) };

Update references to ShippingMethod.description

If your code references the ShippingMethod.description field, change it to The description is now used for an (optional) long-form detailed description.

Deprecated fields

The following fields in the GraphQL APIs are deprecated (but still exist for now):

  • OrderItem.unitPriceIncludesTax: unitPrice is now always without tax
  • OrderLine.totalPrice: Use linePriceWithTax instead
