Getting Started

Setting up the database

Set up the postgres database according to application.properties file or run docker-compose up in src/main/resources to deploy postgres image.

If you are using Docker for postgres database be sure to modify application.properties according to docker-compose.yml file. Use user, password, and port from docker config:

version: "3.9"

services:
db:
image: postgres
environment:
POSTGRES_USER: root
POSTGRES_PASSWORD: root
ports:
- "5499:5432"
volumes:
- reactive_data:/var/lib/postgresql/data
volumes:
reactive_data:

Next step is to define the schema and tables.
Please use the script provided in schema.sql to create the schema and needed tables.

Running the app

The application uses Spring Boot so it is easy to run. You can start it any of a few ways:

• Run the main method from ReactiveApiApplication
• Use the Maven Spring Boot plugin: mvn spring-boot:run

Using the app

Two routes are exposed in ProductController:

• /products - to get merged and formatted products from heroku routes and store metadata for each heroku request
• /products/stats - for getting response time statistics for a current day

Enjoy.
