Integração de Node com MYSQL

Nesse Projeto Fizemos um CRUD Com

  • Nodejs
  • Express
  • Mysql
  • Handlebars

Inserindo Dados

  • Para inserir dados no banco de dados foi criado e executado uma query seguindo os padrões do MYSQL.
  • iremos faser uso do insert.
const sql = ` INSERT INTO books (title, autor, pageqty) VALUES('${title}','${autor}','${pageqty}')`

Resgatando e Editando Dados

  • Para resgatar um dado especifico vamos precisar utilizar o WHERE.
  • Desta forma conseguiremos pegar pelo ID.
  const sql = `SELECT * FROM books WHERE id = ${id}`
  • A edição dos dados será feito na rota post.
const sql = ` UPDATE books SET title = '${title}',autor = '${autor}', pageqty = '${pageqty}' WHERE id = ${id}`

Excluindo Dados

  • Para revover um item vamos utilizar a query DELETE.
  • Precisamos enviar para rota Post.
const sql = `DELETE FROM books WHERE id = ${id}`
