This recipe demonstrates how to load a file from Cloud Storage.

Follow the Cloud Functions quickstart guide to setup Cloud Functions for your project.

Clone this repository:

 git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git
 cd nodejs-docs-samples/functions/gcs

Create a Cloud Storage Bucket to stage our deployment:
```
 gsutil mb gs://[YOUR_BUCKET_NAME]
```
- Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.
Upload the sample file to the bucket:
```
 gsutil cp sample.txt gs://[YOUR_BUCKET_NAME]
```
- Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.
Deploy the "wordCount" function with an HTTP trigger:
```
 gcloud alpha functions deploy wordCount --bucket [YOUR_BUCKET_NAME] --trigger-http --entry-point map
```
- Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.
Call the "wordCount" function using the sample file:
```
 gcloud alpha functions call wordCount --data '{"bucket":"[YOUR_BUCKET_NAME]","file":"sample.txt"}'
```
- Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.
You should see something like this in your console
```
 The file sample.txt has 114 words
```
