Set up the environment

To run the examples, you need to set up the environment. The examples are based on Docker and Docker Compose. To set up the environment, run the following command:

cd examples
sh scripts/start.sh

To down the environment, run:

sh scripts/stop.sh

The environment contains the following services:

• PostgreSQL database
• MinIO object storage

• Hugr server
• Prometheus for monitoring
• Grafana for visualization

Examples

1. Get started

Folder: get-started/

In this example we will set up a Northwind database on PostgreSQL and create GraphQL SDL schema for it.

2. PostgresSQL example

In this example we will create an empty data PostgreSQL data base, describe it in GraphQL SDL and attach it into Hugr as a data source. Folder: postgres-examples/
