chore: Initialize method for modules (#3649)
What:
- Export initialize methods for all modules to be used as a package.
- Export `runMigrations` and `revertMigration` on modules that DB migrations are available
```typescript
import {
initialize as initializeInventory,
InventoryServiceInitializeOptions,
runMigrations as runMigrationsInventory,
} from "@medusajs/inventory";
import { initialize as eventBusInitialize } from "@medusajs/event-bus-redis";
import { initialize as cacheInitialize } from "@medusajs/cache-redis";
const eventBus = await eventBusInitialize({
redisUrl: "localhost",
});
const cache = await cacheInitialize({
redisUrl: "localhost",
});
const options: InventoryServiceInitializeOptions = {
database: {
type: "postgres",
url: `postgres://postgres:@localhost/inventory`,
},
};
await runMigrationsInventory({
options,
});
const inventoryService = await initializeInventory(options, {
eventBusService: eventBus,
});
const sku = "sku_123"
const item = await service.createInventoryItem({
sku,
});
cache.set(sku, { item });
```
