# Using External libraries in Node
|
|
|
|
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. Install the faker module in your `handler.js` file
|
|
|
|
Inside of `handler.js` require your module.
|
|
|
|
`const faker = require('faker');`
|
|
|
|
## 1. Deploy
|
|
|
|
`serverless deploy` or `sls deploy`.
|
|
|
|
`sls` is shorthand for the serverless CLI command
|
|
|
|
Alternatively, you can run `npm run deploy` and deploy via NPM script defined in the `package.json` file
|
|
|
|
## 2. Invoke
|
|
|
|
`serverless invoke --function helloRandomName` or `sls invoke -f helloRandomName`
|
|
|
|
`-f` is shorthand for `--function`
