Automatically generate models for SequelizeJS. Support javascript, typescript, egg.js and midway.
$ npm install -g sequelize-automateYou'll also have to manually install the driver for your database of choice:
# One of the following:
$ npm install -g pg pg-hstore # Postgres
$ npm install -g mysql2
$ npm install -g mariadb
$ npm install -g sqlite3
$ npm install -g tedious # Microsoft SQL Server$ npm install sequelize-automate --saveYou'll also have to manually install the driver for your database of choice:
# One of the following:
$ npm install --save pg pg-hstore # Postgres
$ npm install --save mysql2
$ npm install --save mariadb
$ npm install --save sqlite3
$ npm install --save tedious # Microsoft SQL ServerUsage: sequelize-automate -t [type] -h <host> -d <database> -u <user> -p [password] -P [port] -e [dialect] -o [/path/to/models] -c [/path/to/config]
Options:
--version Show version number [boolean]
--help Show help [boolean]
--type, -t Which code style want to generate.
[choices: "js", "ts", "egg", "midway", "@ali/midway"]
--host, -h IP/Hostname for the database. [string] [default: "localhost"]
--database, -d Database name. [string] [default: "test"]
--user, -u Username for database. [string] [default: "root"]
--password, -p Password for database. [string] [default: "root"]
--port, -P Port number for database. e.g. MySQL/MariaDB: 3306, Postgres:
5432, MSSQL: 1433 [number]
--dialect, -e The dialect/engine that you're using: mysql, sqlite, postgres,
mssql
[choices: "mysql", "sqlite", "postgres", "mssql"] [default: "mysql"]
--output, -o What directory to place the models.
[string] [default: "models"]
--camel, -C Use camel case to name models [boolean] [default: false]
--config, -c Sequelize automate config file, see README.md [string]
--emptyDir, -r Remove all files in `dir` and `typesDir` directories before
generate models. [boolean] [default: false]
--match, -m Match tables using given RegExp. [string] [default: null]$ sequelize-automate -t js -h localhost -d test -u root -p root -P 3306 -e mysql -o modelsProduces 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.
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"
}
}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.
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.
match: null // RegExp to match table name
}
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.
automate.getDefinitions(): Get all model definitions.sequelize-automatewill use these definitions to generate different codes.automate.run(): Generate model codes.
You can generate different (node.js framework's) codes use type option.
