27 | ## :mag_right: Sobre o projeto
28 |
29 | [Voltar ao topo](#conteudos)
30 |
31 | O objetivo dessa aplicação era criar uma API sem nenhuma dependência externa, apenas utilizando as bibliotecas nativas do NodeJS. Tudo foi feito utilizando 100% Javascript.
32 |
33 | ---
34 |
35 | ### ➡ Front-end
36 | O front-end dessa API também foi feito utilizando 100% Javascript, sem arquivos HTML e CSS pré-criados.
37 |
38 | Para visualizar o resultado acesse o repositório: [joaovictornsv/http-node-api-web](https://github.com/joaovictornsv/http-node-api-web)
39 |
40 | ---
41 |
42 | ### ➡ Banco de Dados
43 | Não foi utilizado nenhum banco de dados, os registros são armazenados em um arquivo `users.txt`. Escolhi trabalhar com txt ao invés de JSON para ter o desafio de ler arquivos usando o Node.
44 |
45 | ---
46 |
47 | ### ➡ Arquitetura
48 | Tentei utilizar, na medida do possível, o conceito da Clean Architecture, separando os arquivos em Controllers, Services e Repository.
49 |
50 | ---
51 |
52 | ### ➡ Tratamento de erros
53 | Como o módulo `http` nativo do Node não nos permite usar o `request.body`, tive que adaptar minhas rotas e validar os dados passados por elas.
54 | Além disso, a estrutura da rota também foi validada, pois diferente de bibliotecas como o ExpressJS, onde passar a string `/users/:id` em uma função de request já nos permite acessar o parâmetro com facilidade, no Node esse acesso não é permitido. Para isso tive que criar modos de obtê-los.
55 |
56 | Para os tratamentos e validações utilizei as famosas RegEx's, as quais aprendi bastante sobre como atuam durante o desenvolvimento desse projeto.
57 |
58 | ---
59 |
60 | ### ➡ Funcionalidades ✔️
61 | A API possui um sistema de CRUD completo (Create, Read, Update and Delete) e possui as seguintes funcionalidades:
62 |
63 | #### Funções principais:
64 | - Listagem de usuários ou usuário único
65 | - Criação de novo usuário
66 | - Alteração de dados de um usuário
67 | - Remoção de um usuário
68 |
69 | #### Outras funcionalidades:
70 | - Validação de dados
71 | - Validação de rotas
72 | - Tratamento de erros usando Middlewares
73 | - Gerador de IDs únicos
74 | - Uso de Controller, Repository e Services
75 |

78 | ## :books: O que aprendi
79 |
80 | [Voltar ao topo](#conteudos)
81 |
82 | Ter que implementar cada etapa da api, desde o tratamento dos dados até o retorno da resposta para o cliente contribuiu bastante para treinar minha lógica de programação, a eficiência em resolver problemas pequenos e também a criar códigos mais legíveis e limpos.
83 | Além disso, aprendi a utilizar RegEx's para realizar várias validações no projeto. Por fim, acredito que criar essa API "pura" me fez evoluir mais um degrau nessa jornada de back-end.
