安裝

Sequelize可通過NPM獲得。

$ npm install --save sequelize# And one of the following:$ npm install --save pg pg-hstore$ npm install --save mysql // For both mysql and mariadb dialects$ npm install --save sqlite3$ npm install --save tedious // MSSQL

建立串連

Sequelize將在初始化時設定一個串連池，因此理想情況下只應為每個資料庫建立一個執行個體。

var sequelize = new Sequelize(‘database‘, ‘username‘, ‘password‘, {  host: ‘localhost‘,  dialect: ‘mysql‘|‘mariadb‘|‘sqlite‘|‘postgres‘|‘mssql‘,  pool: {    max: 5,    min: 0,    idle: 10000  },  // SQLite only  storage: ‘path/to/database.sqlite‘});// Or you can simply use a connection urivar sequelize = new Sequelize(‘postgres://user:[email protected]:5432/dbname‘);

你的第一個模型

模型使用sequelize.define(‘name‘, {attributes}, {options})。

var User = sequelize.define(‘user‘, {  firstName: {    type: Sequelize.STRING,    field: ‘first_name‘ // Will result in an attribute that is firstName when user facing but first_name in the database  },  lastName: {    type: Sequelize.STRING  }}, {  freezeTableName: true // Model tableName will be the same as the model name});User.sync({force: true}).then(function () {  // Table created  return User.create({    firstName: ‘John‘,    lastName: ‘Hancock‘  });});
