Setting up your development environment

✅ What you’ll learn in this module:

• What tools and accounts you need;
• How to install and configure your environment;
• How to run your first local test with a simple endpoint.

Prerequisites

Before you begin, make sure you have the following:

Install dependencies

We’ll be using Google Cloud Functions for hosting, and Functions Framework for local testing.

1. Create a new folder for your connector project:

mkdir weld-custom-connector
cd weld-custom-connector

2. Create and activate a virtual environment:

python3 -m venv venv,
source venv/bin/activate  # Mac/Linux,
venv\Scripts\activate.bat # Windows,

3. Install required packages:

pip install functions-framework requests # May need to use pip3 on Linux

🧪 Build a test function

Create a file called main.py with the following code:

1import functions_framework
2
3@functions_framework.http
4def handler(request):
5    return "Hello, Weld!", 200
6

Then, start the local development server:

functions-framework --target=handler --debug

You should now see a local server running at http://localhost:8080.

Test it in Postman

Open Postman and:

• Make a GET request to http://localhost:8080
• You should receive the response: Hello, Weld!

✅ Your dev environment is now up and running!
