# Using external libraries in Node.js service
|
|
|
|
Make sure `serverless` is installed. [See installation guide](/docs/01-guide/01-installing-serverless.md)
|
|
|
|
## 1. Install dependencies
|
|
|
|
For this example we are going to install the `faker` module from npm.
|
|
|
|
`npm install faker --save`
|
|
|
|
## 2. Use the faker module in your `handler.js` file
|
|
|
|
Inside of `handler.js` require your module.
|
|
|
|
`const faker = require('faker');`
|
|
|
|
## 3. Deploy
|
|
|
|
`serverless deploy`
|
|
|
|
## 4. Invoke
|
|
|
|
`serverless invoke -f helloRandomName`
|
|
|
|
In your terminal window you should see the response from AWS Lambda
|
|
|
|
```bash
|
|
{
|
|
"message": "Hello Floyd"
|
|
}
|
|
```
