Herbs helps you build backend applications faster and adds more value for your domain and business logic. You can find out more about it here Why Herbs?

If you don't want to see a step-by-step tutorial but an application running with Herbs, you can visit our Getting Started section.

In this tutorial, we are going to walk through all main principles of HerbsJS building a simple API GraphQL to a TODO App, to learn how HerbsJS Works.

We will create 2 entities one to represent a List of tasks and other to represent items of this List. After learn how create entities, we will create some use cases to create, read, update and delete Lists and Items from database.

To help us in this process, we are using a herbs-cli which starts up a new project scaffolding.
