To develop locally, create a virtual environment and install your dependencies:
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
Then, run your app:
sls wsgi serve

Navigate to localhost:5000 to see your app running locally.
The postsetup.js prompt will walk you through some setup questions that may be
custom to your use case. This includes:
- Python runtime version;
- Whether you have Docker setup, which assists in packaging dependencies. For more info, check out this post on managing your Python packages with Serverless;
- Whether you want to set up a custom domain that you own, rather than a random assigned one from AWS. For more details on that, look at this post on setting up a custom domain with API Gateway and Serverless.
