sequelize-oro v1.0.5

Sequelize-oro

Automatically generate Migrations, Models and Seeder for SequelizeJS via config file

Produced Migrations, Models are made to compatible with sequelize-cli package.

Install

npm install sequelize-oro

Prerequisites

You will need to install the correct dialect binding before using sequelize-oro.

Usage

Migration

Sequelize migration generate from external config file.

// Used For Generate Migrations from live database
const { SequelizeMigrate } = require('sequelize-oro');
const path = require('path');

require('dotenv-safe').config({
  path: path.join(__dirname, '/.env'),
  sample: path.join(__dirname, '/.env.example'),
});

const env = process.env.NODE_ENV || 'development';
const { [env]: config } = require('./config/config.json');

// Association is only created in lang ts type
// const options = { directory: `${__dirname}/models`, dialect: 'postgres' };
const migration = new SequelizeMigrate(config.database, config.username, config.password, {
  host: config.host,
  dialect: config.dialect,
  caseModel: 'p',
  directory: './db/migrations', // where to write files
  // lang:'ts',
  // tables: ['branch'],
  migrationTimestamp: 20211209091019,
  additional: {
    timestamps: true,
    underscored: true,
    // ...options added to each model
  },
});
migration.run().then((data) => {
  console.log(data.tables);
  // console.log(data.foreignKeys); // table foreign key list
  // console.log(data.indexes);     // table indexes
  // console.log(data.hasTriggerTables); // tables that have triggers
  // console.log(data.relations);   // relationships between models
  // console.log(data.text)         // text of generated models
});

All Basic table data, indexes, functions, triggers, forign keys will be migrated in to specified directory. All migrations files are compatible with sequelize-cli, so after generating migration files, just run

node_modules/.bin/sequelize db:migrate

Migrations are generated in alphabetical table order with given timestamp and after creating all basic tables it will create forign key constraint migrations.

Model

Sequelize Model generate from external config file.

// Used For Generate Models from live database
const { SequelizeModel } = require('sequelize-oro');
const path = require('path');

require('dotenv-safe').config({
  path: path.join(__dirname, '/.env'),
  sample: path.join(__dirname, '/.env.example'),
});

const env = process.env.NODE_ENV || 'development';
const { [env]: config } = require('./config/config.json');

// Association is only created in lang ts type
// const options = { directory: `${__dirname}/models`, dialect: 'postgres' };
const modelGenerate = new SequelizeModel(config.database, config.username, config.password, {
  host: config.host,
  dialect: config.dialect,
  caseModel: 'p',
  directory: './models', // where to write files
  // lang:'ts',
  // tables: ['plan'],
  additional: {
    timestamps: true,
    underscored: true,
    // ...options added to each model
  },
});
modelGenerate.run().then((data) => {
  console.log(data.tables);
  // console.log(data.foreignKeys); // table foreign key list
  // console.log(data.indexes);     // table indexes
  // console.log(data.hasTriggerTables); // tables that have triggers
  // console.log(data.relations);   // relationships between models
  // console.log(data.text)         // text of generated models
});

All Model data with relations and indexes will be generated from live database. Generated Model is compatible sequelize-cli.

Seeders

Sequelize Seeder Generate from live Database

// Used For Generate Models from live database
const { SequelizeSeeder } = require('sequelize-oro');
const path = require('path');

require('dotenv-safe').config({
  path: path.join(__dirname, '/.env'),
  sample: path.join(__dirname, '/.env.example'),
});

const env = process.env.NODE_ENV || 'development';
const { [env]: config } = require('./config/config.json');

// Association is only created in lang ts type
// const options = { directory: `${__dirname}/models`, dialect: 'postgres' };
const seederGenerate = new SequelizeSeeder(config.database, config.username, config.password, {
  logging: false,
  host: config.host,
  dialect: config.dialect,
  caseModel: 'p',
  directory: './db/seeders', // where to write files
  seederTimestamp: 20211209091019,
  // to avoid forign key dependency error it is ncessary to insert in certain order
  tables: ['city', 'role', 'user', 'address'],
  tableOptions: {
    city: {
      conditions: [
        {
          column: 'is_deleted',
          condition: '=',
          value: false,
        },
      ],
    },
    user: {
      conditions: [
        {
          column: 'is_deleted',
          condition: '=',
          value: false,
        },
        {
          column: 'id',
          condition: 'IN',
          value: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12],
        },
      ],
    },
    role: {
      conditions: [
        {
          column: 'is_deleted',
          condition: '=',
          value: false,
        },
      ],
    },
    address: {
      conditions: [
        {
          column: 'is_deleted',
          condition: '=',
          value: false,
        },
        {
          column: 'user_id',
          condition: 'IS NOT',
          quotes: false,
          value: 'NULL',
        },
      ],
    },
  },
});
seederGenerate.run().then((data) => {
  // console.log(data.tables);
  // console.log(data.foreignKeys); // table foreign key list
  // console.log(data.indexes);     // table indexes
  // console.log(data.hasTriggerTables); // tables that have triggers
  // console.log(data.relations);   // relationships between models
  // console.log(data.text)         // text of generated models
});

Seeders can be generated with conditions and optional columns can be skipped from remote database.

How to Run Config files

Open package.json and add thos two scripts to execute Migration and Model or directly run scripts using node command

"scripts": {
    "generate_model": "node sequelizeModel.js",
    "generate_migration": "node sequelizeMigration.js"
  },

Now Finally Generate sequelize Models and Migration using following commands

npm run generate_model

npm run generate_migration
