Objetivo

Este Projeto tem o objetivo de exemplificar o uso ElasticSeach e GraphQL

Tecnologias aplicadas

Este projeto as seguintes tecnologias:

• Backend DOTNET:
  • Serviços API
  • DDD
  • CQRS
  • EDD
  • MediatR
  • Redis
  • ElasticSeach
  • GraphQL
  • Entity

Projeto

• Feito no padrão DDD, CQRS, EDD.
• Quando executado algum command é disparado evento notificando ação no elastic.
• Controlers separados para API e GraphQL
• Exemplificado insert, udpdate e delete com graphQL.
• Exemplicicado chamada com GraphQL para Query separadas com banco de dados e Elastic

Rodar no Dokcer:

• ElasticSeach:
  docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" -e "xpack.security.enabled=false" docker.elastic.co/elasticsearch/elasticsearch:8.11.1

docker pull docker.elastic.co/elasticsearch/elasticsearch:8.11.1

• Redis:
  docker run -d -p 6379:6379 redis

• Postgres:
  docker run -d --name postgres-apitest -e POSTGRES_USER=admin -e POSTGRES_PASSWORD=root -e POSTGRES_DB=apitest -p 5432:5432 postgres:15

• DotNet migration:
  dotnet ef migrations add InitialCreate
  dotnet ef database update

Usando com GraphQL

Url: https://localhost:7105/api/v1/graphql/

• Exemplos:

Insert usando graphql:
mutation { createProduct(name: "Teste", price: 11) { id name price } }

Update usando graphql:
mutation { updateProduct( id: "01956213-1264-73a1-93ab-35f93a929cf8" name: "Updated Product Name" price: 99.99 ) { id name price } }

Delete usando graphql:
mutation { deleteProduct( id: "01956213-1264-73a1-93ab-35f93a929cf8" ) }

Busca no banco product by id:
query { getProductById ( id: "01956213-1264-73a1-93ab-35f93a929cf8" ) { id name price } }

Busca no Ellastic product by id:
query { getElasticProductById ( id: "01956213-1264-73a1-93ab-35f93a929cf8" ) { id name price } }

Busca no Ellastic product by name:
query { getElasticProductsByName ( name: "aa" ) { id name price } }

Busca no banco product by name:
query { getProductsByName ( name: "aa" ) { id name price } }

TODO

• add getall com paginação
• add frontend em angular, blazor e nesxtjs
• add signalr
• revisar arquitetura
