## Inventory Module
|
||
|
||
### Step 1: Install Inventory Module
|
||
|
||
To install the Inventory Module, run the following command in the root directory of the Medusa backend:
|
||
|
||
```bash npm2yarn
|
||
npm install @medusajs/inventory
|
||
```
|
||
|
||
### Step 2: Add Inventory Module to Configurations
|
||
|
||
In `medusa-config.js`, add the inventory module to the exported object under the `modules` property:
|
||
|
||
```js
|
||
module.exports = {
|
||
// ...
|
||
modules: {
|
||
// ...
|
||
inventoryService: {
|
||
resolve: "@medusajs/inventory",
|
||
},
|
||
},
|
||
}
|
||
```
|
||
|
||
### Step 3: Run Migrations of Inventory Module
|
||
|
||
Run the following command to reflect schema changes into your database:
|
||
|
||
```bash
|
||
medusa migrations run
|
||
```
|
||
|
||
### Step 4: Run Migration Script
|
||
|
||
After installing the Stock Location module, make sure to [run the migration script](#run-migration-script)

## Stock Location Module
|
||
|
||
### Step 1: Install Stock Location Module
|
||
|
||
To install the Stock Location Module, run the following command in the root directory of the Medusa backend:
|
||
|
||
```bash npm2yarn
|
||
npm install @medusajs/stock-location
|
||
```
|
||
|
||
### Step 2: Add Stock Location Module to Configurations
|
||
|
||
In `medusa-config.js`, add the stock location module to the exported object under the `modules` property:
|
||
|
||
```js
|
||
module.exports = {
|
||
// ...
|
||
modules: {
|
||
// ...
|
||
stockLocationService: {
|
||
resolve: "@medusajs/stock-location",
|
||
},
|
||
},
|
||
}
|
||
```
|
||
|
||
### Step 3: Run Migrations of Stock Location Module
|
||
|
||
Run the following command to reflect schema changes into your database:
|
||
|
||
```bash
|
||
medusa migrations run
|
||
```
|
||
|
||
### Step 4: Run Migration Script
|
||
|
||
After installing both modules, make sure to [run the migration script](#run-migration-script)
|
||
|
||

|
||
|
||
## Run Migration Script
|
||
|
||
After installing both modules, run the following command to migrate current product variant information to fit the schema changes introduced by the modules:
|
||
|
||
```bash
|
||
node ./node_modules/@medusajs/medusa/dist/scripts/migrate-inventory-items.js
|
||
```
|
||
|
||
You can now start the Medusa backend and use the stock location module in your commerce application.
