如何停止续集的连接？

Question

我正在使用sequelize作为ORM在节点中开发一个应用程序，我需要该sequelize在应用程序启动后不要尝试连接到数据库，我需要在填写与连接数据的表格后这样做数据库

const Sequelize = require('sequelize');
const config = require('./config');

const sequelize = new Sequelize(
  config.dbname,
  config.userSQL,
  config.passwordSQL,
  {
    host: config.servidor,
    dialect: 'mssql',
    pool: {
      max: 5,
      min: 0,
      idle: 20000,
    },
    define: {
      timestamps: false,
    },
    logging: false,
  },
);
sequelize
  .authenticate()
  .then(() => {
    console.log('connection.');
  })
  .catch(err => {
    console.error('ERROR CONNECTIONS', err);
  });
module.exports = sequelize;
