Prerequisites
The goal of this developer guide is to walk through all the steps in building a new voter registration backend service module on top of DIGIT.
In this guide, you will learn:
  • How to set up your development environment
  • How to develop the registries, services, APIs for a voter registration module that were described in the Design Guide
  • How to integrate with an existing DIGIT environment and re-use a lot of the common services using Kubernetes port forwarding
  • How to test the new module and debug
  • How to build and deploy the new service in your DIGIT environment
At the end of this guide, you will be able to run the sample module provided with this guide (code provided), test it out locally and also deploy it using CD/CI to your dev environment.
