This sample shows calling the success and failure callbacks.

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/module
   

3. 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.

4. Deploy the helloworld function with an HTTP trigger:

    gcloud alpha functions deploy helloworld --bucket [YOUR_BUCKET_NAME] --trigger-http
   

   • Replace [YOUR_BUCKET_NAME] with the name of your Cloud Storage Bucket.

5. Call the helloworld function with some data:

    gcloud alpha functions call helloworld --data '{"message":"keyboard cat"}'
   

6. Call the helloworld function without any data:

    gcloud alpha functions call helloworld
   

   You should see something like this in your console:

    executionId: abcd1234-0
    result: Hello World!
   

7. Check the logs for the helloworld function:

    gcloud alpha functions get-logs helloworld
   

   You should see something like this in your console:

    D      ... User function triggered, starting execution
    I      ... keyboard cat
    D      ... Execution took 1 ms, user function completed successfully
