node.js模块导出返回和使用对象

使命感 require('./models/modelConfig');

您应该调用该方法以获取实例:

const seqInitializer = require('./models/modelConfig');
const seq = seqInitializer();

或者。直接返回sequelize即可:

const Sequelize = require('sequelize');
const dbConfig = require('../config/database.config');
function initSequelize() {

    const sequelize = new Sequelize(dbConfig.database, dbConfig.user, dbConfig.password, {
        host: 'localhost',
        dialect: 'mysql',

        pool: {
            max: 5,
            min: 0,
            acquire: 30000,
            idle: 10000
        },

        // http://docs.sequelizejs.com/manual/tutorial/querying.html#operators
        operatorsAliases: false
    });


    const employee = sequelize.define('employee', {
        id:{
            type: Sequelize.DataTypes.INTEGER,
            primaryKey: true
        },
        token: Sequelize.DataTypes.TEXT
    });

    return sequelize;


};
module.exports = initSequelize();

const seq = require('./models/modelConfig')();
