Using Python Requirements with Serverless Framework

If you need to include a PyPI package with your function, you will need to vendor it when packaging your function. This can be done by using pip install --target package ... before deploying.

Here's a simple example to achieve that with Serverless Framework.

Testing with serverless offline for Python

In order to test your function locally before deployment in a serverless function, you can install our offline testing library with:

pip install -r requirements-dev.txt

Import your environment variables using:

export database_model="english-corpus.sqlite3"

Launch your function locally:

python python-dependencies.py

Test your local function using curl:

curl -i -X POST localhost:8080 -d '{"message":"Hello"}'

Setup

First, you need to set up the Serverless Framework.

Then, you can run:

# Install node dependencies
npm install

# Deploy
./bin/deploy.sh

The deploy command should print the URL of the new function. You can then use curl to check that it works, and should see the response:

Response status: 200
