What:
- Definition of all Modules links
- `link-modules` package to manage the creation of all pre-defined link or custom ones
```typescript
import { initialize as iniInventory } from "@medusajs/inventory";
import { initialize as iniProduct } from "@medusajs/product";
import {
initialize as iniLinks,
runMigrations as migrateLinks
} from "@medusajs/link-modules";
await Promise.all([iniInventory(), iniProduct()]);
await migrateLinks(); // create tables based on previous loaded modules
await iniLinks(); // load link based on previous loaded modules
await iniLinks(undefined, [
{
serviceName: "product_custom_translation_service_link",
isLink: true,
databaseConfig: {
tableName: "product_transalations",
},
alias: [
{
name: "translations",
},
],
primaryKeys: ["id", "product_id", "translation_id"],
relationships: [
{
serviceName: Modules.PRODUCT,
primaryKey: "id",
foreignKey: "product_id",
alias: "product",
},
{
serviceName: "custom_translation_service",
primaryKey: "id",
foreignKey: "translation_id",
alias: "transalation",
deleteCascade: true,
},
],
extends: [
{
serviceName: Modules.PRODUCT,
relationship: {
serviceName: "product_custom_translation_service_link",
primaryKey: "product_id",
foreignKey: "id",
alias: "translations",
isList: true,
},
},
{
serviceName: "custom_translation_service",
relationship: {
serviceName: "product_custom_translation_service_link",
primaryKey: "product_id",
foreignKey: "id",
alias: "product_link",
},
},
],
},
]); // custom links
```
Remote Link
```typescript
import { RemoteLink, Modules } from "@medusajs/modules-sdk";
// [...] initialize modules and links
const remoteLink = new RemoteLink();
// upsert the relationship
await remoteLink.create({ // one (object) or many (array)
[Modules.PRODUCT]: {
variant_id: "var_abc",
},
[Modules.INVENTORY]: {
inventory_item_id: "iitem_abc",
},
data: { // optional additional fields
required_quantity: 5
}
});
// dismiss (doesn't cascade)
await remoteLink.dismiss({ // one (object) or many (array)
[Modules.PRODUCT]: {
variant_id: "var_abc",
},
[Modules.INVENTORY]: {
inventory_item_id: "iitem_abc",
},
});
// delete
await remoteLink.delete({
// every key is a module
[Modules.PRODUCT]: {
// every key is a linkable field
variant_id: "var_abc", // single or multiple values
},
});
// restore
await remoteLink.restore({
// every key is a module
[Modules.PRODUCT]: {
// every key is a linkable field
variant_id: "var_abc", // single or multiple values
},
});
```

@medusajs/event-bus-local
Documentation | Website
An open source composable commerce engine built for developers.
Overview
Local Event Bus module for Medusa. When installed, the events system of Medusa is powered by the Node EventEmitter. This module installed by default in new (> v1.8.0) Medusa projects.
The Node EventEmitter is limited to a single process environment. We generally recommend using the @medusajs/event-bus-redis module in a production environment.
Getting started
Install the module:
yarn add @medusajs/event-bus-local
You don't need to add the module to your project configuration as it is the default one. Medusa will try to use it, if no other event buses are installed.
module.exports = {
// ...
modules: [ ... ],
// ...
}
Configuration
The module comes with no configuration options.
