This page shows you how to install and run
Functions Frameworks for local
development.
Before you begin
If this is your first time using Cloud Run functions
with Cloud Code, see the
Get started with Cloud Run functions
quickstart. Once you've created and deployed a function using a
Cloud Code sample, you can return to this guide to setup a local
development environment.
Install and run Functions Framework locally
To install and run Functions Framework locally, follow these steps:
In VS Code, click
Cloud Code and then expand the Cloud Functions explorer.
Expand your Trusted Cloud project, right-click a deployed function of
your choice, and select Download to new workspace. This downloads the source
code of your function from Trusted Cloud to your local machine and
creates a new workspace in your IDE.
Click View > Terminal
to open the terminal in VS Code.
To install the local dependencies to your function's local folder, navigate
to your function's local folder in the terminal and then run the following:
Node.js
npminstall
Python
pipinstallfunctions-framework
To run the local Functions Framework, run the following:
Node.js
npxfunctions-framework--target=entryPoint
Python
functions-framework--target=entryPoint
To find the entryPoint of your function, open your launch.json file and
look for the assigned value of entryPoint.
For example, if you're using Cloud Code's Hello World sample
application, the configuration appears as follows:
"entryPoint": "helloHttp",
To test your function, when prompted, click Open in Browser, or click
+ New Terminal and run the following:
curl http://localhost:8080/
This shows the context of the function in the terminal.
