Integrating the contact assistant into applications

Next, we will create the layers to integrate the contact assistant capability into applications. As mentioned at the beginning of this chapter, we will not implement any application; we will only implement the service and RESTful endpoint layers.

As with previous hands-on projects, we will be using Python, Pipenv, Chalice, and boto3 as part of the technology stack. Let's create a project structure first.

1. In the terminal, we will create the root project directory and enter it with the following commands:

$ mkdir ContactAssistant
$ cd ContactAssistant

2. We will create a Python 3 virtual environment with Pipenv in the project's root directory. Our Python portion of the project requires two packages, boto3 and chalice. We can install them with the following commands:

$ pipenv --three
$ pipenv install boto3
$ pipenv install...
