Example

$ sequelize-automate -t js -h localhost -d test -u root -p root -P 3306  -e mysql -o models

Produces a file/files such as ./models/user.js which looks like:

const {
  DataTypes 
= require('sequelize');
 
module.exports = sequelize => {
  const attributes = {
    id: {
      type: DataTypes.INTEGER(11).UNSIGNED,
      allowNull: false,
      defaultValue: null,
      primaryKey: true,
      autoIncrement: true,
      comment: "primary ket",
      field: "id"
    },
    name: {
      type: DataTypes.STRING(100),
      allowNull: false,
      defaultValue: null,
      primaryKey: false,
      autoIncrement: false,
      comment: "user name",
      field: "name",
      unique: "uk_name"
    },
    email: {
      type: DataTypes.STRING(255),
      allowNull: false,
      defaultValue: null,
      primaryKey: false,
      autoIncrement: false,
      comment: "user email",
      field: "email"
    },
    createdAt: {
      type: DataTypes.DATE,
      allowNull: false,
      defaultValue: null,
      primaryKey: false,
      autoIncrement: false,
      comment: "created datetime",
      field: "created_at"
    },
    updatedAt: {
      type: DataTypes.DATE,
      allowNull: false,
      defaultValue: null,
      primaryKey: false,
      autoIncrement: false,
      comment: "updated datetime",
      field: "updated_at"
    }
  };
  const options = {
    tableName: "user",
    comment: "",
    indexes: []
  };
  const UserModel = sequelize.define("userModel", attributes, options);
  return UserModel;
};

Which makes it easy for you to simply Sequelize.import it.

Configuration options

You can use -c, --config option to specify a configuration file.

$ sequelize-automate -c "./sequelize-automate.config.json"

For now, you must create a file called sequelize-automate.config.json with the following content:

{
  "dbOptions": {
    "database": "test",
    "username": "root",
    "password": "root",
    "dialect": "mysql",
    "host": "localhost",
    "port": 3306,
    "logging": false
  },
  "options": {
    "type": "js",
    "dir": "models"
  }
}

Or a .js file: sequelize-automate -c "./sequelize-automate.config.js"

module.exports = {
  dbOptions: {
    database: "test",
    username: "root",
    password: "root",
    dialect: "mysql",
    host: "localhost",
    port: 3306,
    logging: false
  },
  options: {
    type: "js",
    dir: "models"
 }
}

In project

Also, you can use sequelize-automate in project.

First add a configuration file sequelize-automate.config.json as above and add automate script to package.json:

"script"{
  "automate": "sequelize-automate -c sequelize-automate.config.json"
}

Then you can use npm run automate to generate models.

Programmatic API

const Automate = require('sequelize-automate');
 
// Database options, is the same with sequelize constructor options.
const dbOptions = {
  database: 'test',
  username: 'root',
  password: 'root',
  dialect: 'mysql',
  host: '127.0.0.1',
  port: 3306,
  define: {
    underscored: false,
    freezeTableName: false,
    charset: 'utf8mb4',
    timezone: '+00:00',
    dialectOptions: {
      collate: 'utf8_general_ci',
    },
    timestamps: false,
  },
};
 
// Automate options
const options = {
  type: 'js', // Which code style want to generate, supported: js/ts/egg/midway. Default is `js`.
  camelCase: false, // Model name camel case. Default is false.
  fileNameCamelCase: true, // Model file name camel case. Default is false.
  dir: 'models', // What directory to place the models. Default is `models`.
  typesDir: 'models', // What directory to place the models' definitions (for typescript), default is the same with dir.
  emptyDir: false, // Remove all files in `dir` and `typesDir` directories before generate models.
  tables: null, // Use these tables, Example: ['user'], default is null.
  skipTables: null, // Skip these tables. Example: ['user'], default is null.
  tsNoCheck: false, // Whether add @ts-nocheck to model files, default is false.
}
 
const automate = new Automate(dbOptions, options);
 
(async function main() {
  // // get table definitions
  // const definitions = await automate.getDefinitions();
  // console.log(definitions);
 
  // or generate codes
  const code = await automate.run();
  console.log(code);
})()

Database options dbOptions is the same with sequelize constructor options, you can find all options here: https://sequelize.org/master/class/lib/sequelize.js~Sequelize.html#instance-constructor-constructor.

Methods

  • automate.getDefinitions(): Get all model definitions. sequelize-automate will use these definitions to generate different codes.
  • automate.run(): Generate model codes.

Type

You can generate different (node.js framework's) codes use type option.
