This Java application, built with Java 17 and Quarkus, provides a RESTful API for managing favorite recipes.

• The application is developed using Java 17.

• Quarkus is used as the underlying framework for building the application.

• The application allows users to add, update, remove, and fetch recipes.
• Users can filter recipes based on the following criteria:
  1. Whether the dish is vegetarian.
  2. The number of servings.
  3. Specific ingredients (include or exclude).
  4. Text search within the instructions.

The project follows a standard Maven project structure. Key files and directories include:

• src/main: Contains the main application code.
• src/test: Contains unit and integration tests.
• pom.xml: Maven Project Object Model file with project configuration.

The project includes the following dependencies managed by Quarkus:

• Quarkus Container Image Docker
• Quarkus RestEasy Reactive Jackson
• Quarkus Arc
• Quarkus Hibernate ORM Panache
• Quarkus Hibernate Validator
• Quarkus Liquibase
• Quarkus JDBC PostgreSQL
• Quarkus Config YAML
• Quarkus HAL
• Quarkus Hibernate Search ORM Elasticsearch
• Quarkus JUnit 5

Additionally, the following test dependencies are included:

• Testcontainers
• PostgreSQL (Testcontainers)
• Rest Assured

You can build the project and run the application using Docker:

sh ./build-demo.sh // Or chmod +x ./build-demo.sh && ./build-demo.sh

Use the provided docker-compose file to quickly deploy the application

docker compose up -d 

Make sure to provide Postgresql and elasticsearch passwords in a .env file

POSTGRES_USER=recipesdb
POSTGRES_PASSWORD=<postgres_password>
ELASTIC_PASSWORD=<elastic_password>

The application includes three independent endpoints:

1. The main 'Recipe' endpoint (/recipes) that manage recipes properties and dependencies
2. A secondary 'Ingredient' endpoint (/ingredients) that manage ingredients so that they can be shared among different recipes
3. A third 'Tag' endpoint (/tags) that allow the creation of recipes' tags making the retrieval of vegetarian recipes easy and allows to extend to any possible tag (for instance 'Asian cuisine', 'Gluten-free' ...)

In addition, comes a search endpoint (/search) to perform full text search based on the recipe and ingredients properties, it uses an Elasticsearch reverse index to index Recipes and ingredient properties.
