|
||
|
||
The Local Event Bus Module uses Node EventEmitter to implement Medusa's pub/sub events system. The Node EventEmitter is limited to a single process environment.
|
||
|
||
This module is useful for development and testing, but it’s not recommended to be used in production.
|
||
|
||
For production, it’s recommended to use modules like [Redis Event Bus Module](../redis/page.mdx).
|
||

|
||
|
||
## Install the Local Event Bus Module
|
||
|
||
To install Local Event Bus Module, run the following command in the directory of your Medusa application:
|
||
|
||
```bash npm2yarn
|
||
npm install @medusajs/event-local
|
||
```
|
||
|
||
Next, add the module into the `modules` property of the exported object in `medusa-config.js`:
|
||
|
||
```js title="medusa-config.js"
|
||
const { Modules } = require("@medusajs/modules-sdk")
|
||
|
||
// ...
|
||
|
||
module.exports = {
|
||
// ...
|
||
modules: {
|
||
// ...
|
||
[Modules.EVENT_BUS]: true,
|
||
},
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## Test the Module
|
||
|
||
To test the module, start the Medusa application:
|
||
|
||
```bash npm2yarn
|
||
npm run dev
|
||
```
|
||
|
||
You'll see the following message in the terminal's logs:
|
||
|
||
```bash noCopy noReport
|
||
Local Event Bus installed. This is not recommended for production.
|
||
```
