Architecture and Objectives

The architecture we'll implement will look like this.

Core concepts

Please check out this page for a quick overview of some key concepts like subgraph, supergraph, sources, etc.

API Producers: connecting data sources

Our Supergraph has 3 subgraphs - one each for Postgres, MongoDB and a microservice. In this section, we'll add these subgraphs to our supergraph.

how to handle the collaborators thing? Test with personal email ID as collaborator

Prerequisites

1. Sign up at https://console.hasura.io/ using your Siemens emails.
2. Post login you'll see option to join our project as a collaborator - accept the invite.

3. Install the new Hasura CLI: follow instructions at https://hasura.io/docs/3.0/cli/installation/

   • POWERSHELL IS RECOMMENDED FOR WINDOWS USERS

4. Assuming you have Visual Studio Code installed already, install the Hasura extension

what is the point of getting added as a collaborator? How do I create a subgraph "inside a project" - is this done via the folder structure? For now create a new project and proceed and see what happens

Adding PostgreSQL subgraph

Instructions with create new poject flow

1. Create new project and cd into the folder
2. ddn add connector-manifest app_connector --subgraph app --hub-connector hasura/postgres --type cloud
   • This assumes that your project already has a subgraph named app (Which it does by default). So, don't change this.

Usage
