Automatically generate models for SequelizeJS via the command line.
npm install -g sequelize-auto
# for this fork
# support indexes
# support egg framework
# optimize generated model object key and value commmas
npm install -g icai/sequelize-autoYou will need to install the correct dialect binding globally before using sequelize-auto.
Example for MySQL/MariaDB
npm install -g mysql
Example for Postgres
npm install -g pg pg-hstore
Example for Sqlite3
npm install -g sqlite
Example for MSSQL
npm install -g mssql
[node] sequelize-auto -h <host> -d <database> -u <user> -x [password] -p [port] --dialect [dialect] -c [/path/to/config] -o [/path/to/models] -t [tableName] -C
Options:
-h, --host IP/Hostname for the database. [required]
-d, --database Database name. [required]
-u, --user Username for database.
-x, --pass Password for database.
-p, --port Port number for database.
-c, --config JSON file for Sequelize's constructor "options" flag object as defined here: https://sequelize.readthedocs.org/en/latest/api/sequelize/
-o, --output What directory to place the models.
-e, --dialect The dialect/engine that you're using: postgres, mysql, sqlite
-a, --additional Path to a json file containing model definitions (for all tables) which are to be defined within a model's configuration parameter. For more info: https://sequelize.readthedocs.org/en/latest/docs/models-definition/#configuration
-t, --tables Comma-separated names of tables to import
-T, --skip-tables Comma-separated names of tables to skip
-C, --camel Use camel case to name models and fields
-n, --no-write Prevent writing the models to disk.
-s, --schema Database schema from which to retrieve tables
-z, --typescript Output models as typescript with a definitions file.
-f, --camel-file-name Use camel case for file name
-g, --egg Use egg Sequelize
sequelize-auto -o "./models" -d sequelize_auto_test -h localhost -u my_username -p 5432 -x my_password -e postgres
Produces a file/files such as ./models/Users.js which looks like:
/* jshint indent: 2 */
module.exports = function(sequelize, DataTypes) {
return sequelize.define('Users', {
'id': {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
'username': {
type: DataTypes.STRING,
allowNull: true
},
'touchedAt': {
type: DataTypes.DATE,
allowNull: true
},
'aNumber': {
type: DataTypes.INTEGER(11),
allowNull: true
},
'bNumber': {
type: DataTypes.INTEGER(11),
allowNull: true
},
'validateTest': {
type: DataTypes.INTEGER(11),
allowNull: true
},
'validateCustom': {
type: DataTypes.STRING,
allowNull: false
},
'dateAllowNullTrue': {
type: DataTypes.DATE,
allowNull: true
},
'defaultValueBoolean': {
type: DataTypes.BOOLEAN,
allowNull: true,
defaultValue: '1'
},
'createdAt': {
type: DataTypes.DATE,
allowNull: false
},
'updatedAt': {
type: DataTypes.DATE,
allowNull: false
}
}, {
tableName: 'Users',
freezeTableName: true
});
};
Which makes it easy for you to simply Sequelize.import it.
For the -c, --config option the following JSON/configuration parameters are defined by Sequelize's options flag within the constructor. For more info:
https://sequelize.readthedocs.org/en/latest/api/sequelize/
var SequelizeAuto = require('sequelize-auto')
var auto = new SequelizeAuto('database', 'user', 'pass');
auto.run(function (err) {
if (err) throw err;
console.log(auto.tables); // table list
console.log(auto.foreignKeys); // foreign key list
});
With options:
var auto = new SequelizeAuto('database', 'user', 'pass', {
host: 'localhost',
dialect: 'mysql'|'mariadb'|'sqlite'|'postgres'|'mssql',
directory: false, // prevents the program from writing to disk
port: 'port',
additional: {
timestamps: false
//...
},
tables: ['table1', 'table2', 'table3']
//...
})Add -z to cli options or typescript: true to programmatic options. Model usage in a ts file:
// All models, can put in or extend to a db object at server init
import * as dbTables from './models/db.tables';
const tables = dbTables.getModels(sequelize); //:dbTables.ITable
tables.Device.findAll
// Single models
import * as dbDef from './models/db.d';
const devices:dbDef.DeviceModel = sequelize.import('./models/Device');
devices.findAllYou must setup a database called sequelize_auto_test first, edit the test/config.js file accordingly, and then enter in any of the following:
# for all
npm run test
# mysql only
npm run test-mysql
# postgres only
npm run test-postgres
# postgres native only
npm run test-postgres-native
# sqlite only
npm run test-sqlite
