This template configures a single function, api, which is responsible for handling all incoming requests thanks to the httpApi event. To learn more about httpApi event configuration options, please refer to httpApi event docs. As the event is configured in a way to accept all incoming requests, express framework is responsible for routing and handling requests internally. Implementation takes advantage of serverless-http package, which allows you to wrap existing express applications. To learn more about serverless-http, please refer to corresponding GitHub repository.
Install dependencies with:
