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.
    modalNameSuffix: true, // Model name 'Modal' suffix. Default is true.
    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.
    match: null, // RegExp to match table name
    ignorePrefix: null, // Ignore the prefix of table name, Example: ['t_']. Default is null
    attrLength: true, // Whether to generate attribute length(design for freesun，but  use for any type)
}

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.
