What is the Google Cloud Functions Emulator?

The Google Cloud Functions Emulator is a Node.js application that implements the Google Cloud Functions API, and includes a CLI with which you can manage the application.

The Emulator allows you to deploy, run, and debug your Cloud Functions on your local machine before deploying them to the production Google Cloud Functions service.

Note

The Emulator only supports Node v6.x.x. It does not support Node v8.x.x or Python.

How do I get started?

1. Write a function:

    mkdir helloWorld
    cd helloWorld
    touch index.js
    echo 'exports.helloWorld = (req, res) => res.send("Hello, World!");' > index.js
   

2. Install the Emulator:

   NPM:

    npm install -g @google-cloud/functions-emulator
   

   Yarn:

    yarn global add @google-cloud/functions-emulator
   

   Or read more in the detailed installation instructions.

3. Start the Emulator:

    functions start
   

4. Deploy your function:

    functions deploy helloWorld --trigger-http
   

   Get help deploying a function with functions deploy --help.

5. Call your function:

    functions call helloWorld
   

6. View the logs:

    functions logs read
   

Where is the documentation?

For a quick reference, the Emulator CLI is self-documenting. Run the following to get help with the CLI:

functions --help

For everything else see the How-To Guides.
