1 | # Rinha de Backend: 2024/Q1 - Crébito
2 |
3 | POC para a segunda edição da Rinha de Backend feita em Clojure com as libs compojure e next.jdbc.
4 |
5 | ## Pré Requisitos
6 |
7 | Necessário [Leiningen][] 2.0.0 ou superior instaldo.
8 |
9 | [leiningen]: https://github.com/technomancy/leiningen
10 |
11 | ## Para Executar
12 |
13 | Para subir o servidor, execute o seguinte comando:
14 |
15 | lein ring server-headless
16 |
17 | Se quiser alterar a porta, configure a variável de ambiente `PORT` ou adicione `:port ` na chave `:ring` no arquivo [project.clj](./project.clj).
18 |
19 |
20 | ## Conteinerização
21 |
22 | O diretório [containerization](./containerization/) possui diversos exemplos para conteinerização da API. Talvez você precise fazer ajustes para que funcionem.
23 |
24 |
25 | ## Submissão
26 |
27 | O diretório [participacao](./participacao) contem os artefatos usados para a submissão da Rinha de Backend.
