This sample shows a Google Cloud Function that uses a dependency from NPM, and is a handy way to generate a v4 UUID from the command-line.

View the documentation or the source code.

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

2. Clone this repository:

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

3. Deploy the uuid function with an HTTP trigger:

    gcloud functions deploy uuid --trigger-http
   

4. Call the uuid function:

    gcloud functions call uuid
   

   You should see something like this in your console:

    executionId: abcd1234-0
    result: 0ef22088-07f2-44ca-9cef-cea8ff666d69
