Setup

Prerequisites

  1. Install Node.js (and NPM)

  2. Clone this repository:

     git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git
    
  3. Change directory in to the project:

     cd nodejs-docs-samples
    
  4. Set the GCLOUD_PROJECT environment variable:

    Linux:

     export GCLOUD_PROJECT=your-project-id
    

    Windows:

     set GCLOUD_PROJECT=your-project-id
    

    Windows (PowerShell):

     $env:GCLOUD_PROJECT="your-project-id"
    
  5. Obtain authentication credentials.

    Create local credentials by running the following command and following the oauth2 flow (read more about the command here):

     gcloud beta auth application-default login
    

    In non-Google Cloud environments, GCE instances created without the correct scopes, or local workstations where the gcloud beta auth application-default login command fails, use a service account by doing the following:

    • Go to API Manager -> Credentials
    • Click "New Credentials", and create a service account or click here
    • Download the JSON for this service account, and set the GOOGLE_APPLICATION_CREDENTIALS environment variable to point to the file containing the JSON credentials.

    Set the GOOGLE_APPLICATION_CREDENTIALS environment variable:

    Linux:

     export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_file.json
    

    Windows:

     set GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account_file.json
    

    Windows (PowerShell):

     $env:GOOGLE_APPLICATION_CREDENTIALS="/path/to/service_account_file.json"
    

    Note for code running on GCE, GAE, or other environments:

    On Google App Engine, the credentials should be found automatically.

    On Google Compute Engine, the credentials should be found automatically, but require that you create the instance with the correct scopes.

     gcloud compute instances create --scopes="https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/compute,https://www.googleapis.com/auth/compute.readonly" test-instance
    

    If you did not create the instance with the right scopes, you can still upload a JSON service account and set GOOGLE_APPLICATION_CREDENTIALS as described.

    Read more about Google Cloud Platform Authentication.

How to run a sample

  1. Change directory to one of the sample folders, e.g. bigquery:

     cd bigquery/
    
  2. Install the sample's dependencies (see the sample's README for details):

     npm install
    
  3. Run the sample:

     node sample_file.js [args]...
    

How to run the tests

  1. Read the Contributing Guide.

  2. Set the TEST_BUCKET_NAME environment variable to the name of a test Google Cloud Storage bucket:

    Linux:

     export TEST_BUCKET_NAME=your-bucket-name
    

    Windows:

     set TEST_BUCKET_NAME=your-bucket-name
    

    Windows (PowerShell):

     $env:TEST_BUCKET_NAME="your-bucket-name"
    
  3. In a terminal, start Redis:

     redis-server
    
  4. In another terminal, start memcached:

     memcached
    
  5. In another terminal, run the unit tests from the root of the project:

     npm test
    

    or with coverage:

     npm run coverage
    
  6. Then run the system tests from the root of the project:

     npm run system-test
    

    or with coverage:

     npm run system-cover
    
  7. Or run all the tests at once with coverage:

     npm run all-cover
