How to Using Multiple Database in Nodejs

Unfortunately, the Sequelize documentation did not cover this specific topic and multiple stackoverflow posts had to save the day. To save you time, I decided to write a post, summarizing my approach and some helpful tips and tricks.

The Sequelize documentation states:

Sequelize will setup a connection pool on initialization so you should ideally only ever create one instance per database if you’re connecting to the DB from a single process.

This means, that we will need to run a new Sequelize instance for every database we want to connect to our server. The easiest and most flexible way to do this is to declare multiple databases in our config.js and then loop over these databases in the file handling our database connections (in my case this is the index.js of my models folder).

module.exports = {
  /**Declaration of databases for my development environment**/
    "development": {
        "databases": {
            "Database1": {
                "database": process.env.RDS_DATABASE1, //you should always save these values in environment variables
                "username": process.env.RDS_USERNAME1,  //only for testing purposes you can also define the values here
                "password":  process.env.RDS_PASSWORD1,
                "host": process.env.RDS_HOSTNAME1,
                "port": process.env.RDS_PORT1,
                "dialect": "postgres"  //here you need to define the dialect of your databse, in my case it is Postgres
            "Database2": {
                "database": process.env.RDS_DATABASE2, 
                "username": process.env.RDS_USERNAME2,  
                "password":  process.env.RDS_PASSWORD2,
                "host": process.env.RDS_HOSTNAME2,
                "port": process.env.RDS_PORT2,
                "dialect": "mssql"  //second database can have a different dialect


Here we declared two databases — The Postgres Database “Database1” and the MSSQL Database “Database2” — and their credentials for the connection. Now let’s have a look how to read in these declarations and connect to the databases.

const Sequelize = require('sequelize');
const env = process.env.NODE_ENV || 'development';

//Load the configuration from the config.js
const config = require(`${__dirname}/../config/config.js`)[env];

//Create an empty object which can store our databases
const db = {};

//Extract the database information into an array
const databases = Object.keys(config.databases);

//Loop over the array and create a new Sequelize instance for every database from config.js
for(let i = 0; i < databases.length; ++i) {
    let database = databases[i];
    let dbPath = config.databases[database];
    //Store the database connection in our db object
    db[database] = new Sequelize( dbPath.database, dbPath.username, dbPath.password, dbPath );

/**Load Sequelize Models**/


The “db” object now contains information on how to connect to all databases configured in our config.js, but does not contain information about the models in the database, consequently not being able to make correct SQL queries. To give the “db” object the necessary model information, we need to read the information from our model files and add it to the object. To understand the next few lines of code, we first need to have a look at my folder structure. The index.js is located in the models folder, which has two subdirectories for models of both databases from my config.js:

Now lets add the models from both directories to our “db” object in the index.js:

const fs = require('fs');
const path = require('path');
const Sequelize = require('sequelize');
const basename = path.basename(module.filename);
const env = process.env.NODE_ENV || 'development';
const config = require(`${__dirname}/../config/config.js`)[env];
const db = {};
const databases = Object.keys(config.databases);

/** Add Databases**/
for(let i = 0; i < databases.length; ++i) {
    let database = databases[i];
    let dbPath = config.databases[database];
    db[database] = new Sequelize( dbPath.database, dbPath.username, dbPath.password, dbPath );

/**Add the Database Models**/
//Add models from database1 folder
    .readdirSync(__dirname + '/database1')
    .filter(file =>
        (file.indexOf('.') !== 0) &&
        (file !== basename) &&
        (file.slice(-3) === '.js'))
    .forEach(file => {
        const model = db.ebdb.import(path.join(__dirname + '/database1', file));
        db[model.name] = model;

// Add models from database2 folder

    .readdirSync(__dirname + '/database2')
    .filter(file =>
        (file.indexOf('.') !== 0) &&
        (file !== basename) &&
        (file.slice(-3) === '.js'))
    .forEach(file => {
        const model = db.easyconnect.import(path.join(__dirname + '/database2', file));
        db[model.name] = model;

Object.keys(db).forEach(modelName => {
    if (db[modelName].associate) {

module.exports = db;


Now we can require our models in our controllers as usual:

const model1= require('../models').model1;

Congratulations! You added multiple databases to your NodeJS server and made them accessible. Now let’s talk about the tricky part: migrations and seeders

Sequelize is currently not supporting multiple migration folders and is not able to distinguish, which migrations should be ran in each database by itself, if all migration files are kept in one folder. While there are multiple ways to deal with this problem — e.g. manually setting migration filepaths in the sequelize cli — I found the approach using separate options files and npm scripts the most productive:

First lets expand our config.js with environments for migrating and seeding our databases. Every environment then only contains data for one specific database, so we can explicitly define to which database we want to connect:

module.exports = {
    "development": {
        "databases": { /** our database declarations from before**/}

    // Special environment only for Database1
    "Database1": {
                "database": process.env.RDS_DATABASE1, //you should always save these values in environment variables
                "username": process.env.RDS_USERNAME1,  //only for testing purposes you can also define the values here
                "password":  process.env.RDS_PASSWORD1,
                "host": process.env.RDS_HOSTNAME1,
                "port": process.env.RDS_PORT1,
                "dialect": "postgres"  //here you need to define the dialect of your databse, in my case it is Postgres

    // Special environment only for Database2
    "Database2": {
                "database": process.env.RDS_DATABASE2, 
                "username": process.env.RDS_USERNAME2,  
                "password":  process.env.RDS_PASSWORD2,
                "host": process.env.RDS_HOSTNAME2,
                "port": process.env.RDS_PORT2,
                "dialect": "mssql"  //second database can have a different dialect


In the next steps we create new Sequelize options files — similar to our .sequelizerc file — for every database. So lets create these two files in the directory of our package.json file:

  • .sequelize-database1
  • .sequelize-database2

In these files, we can define in which directory our config, models, migrations and seeders are stored:

const path = require('path');

module.exports = {
    "config": path.resolve('./server/config', 'config.js'),
    "models-path": path.resolve('./server/models'),
    "seeders-path": path.resolve('./server/seeders/database1'),
    "migrations-path": path.resolve('./server/migrations/database1')


const path = require('path');

module.exports = {
    "config": path.resolve('./server/config', 'config.js'),
    "models-path": path.resolve('./server/models'),
    "seeders-path": path.resolve('./server/seeders/database2'),
    "migrations-path": path.resolve('./server/migrations/database2')


Finally we can use these options files in npm scripts, that run our migrations oder seeders. Therefore we need to add some lines to the scripts section of package.json file:


  "scripts": {

      "sequelize:database1:migrate": "sequelize --options-path ./.sequelize-database1 --env database1 db:migrate",
      "sequelize:database1:migrate:undo": "sequelize --options-path ./.sequelize-database1 --env database1 db:migrate:undo",
      "sequelize:database1:seed:all": "sequelize --options-path ./.sequelize-database1 --env database1 db:seed:all",

      "sequelize:database2:migrate": "sequelize --options-path ./.sequelize-database2 --env database2 db:migrate",
      "sequelize:database2:migrate:undo": "sequelize --options-path ./.sequelize-database2 --env database2 db:migrate:undo",
      "sequelize:database2:seed:all": "sequelize --options-path ./.sequelize-database2 --env database2 db:seed:all",


The scripts use the two .sequelize-database1, .sequelize-database2 options files to determine the location of the configuration, models, migrations and seeder directories and set the correct environment for reading configurations from the config.js file.

You can run the scripts with an npm run command from the command line:

npm run sequelize:database1:migrate

I hope this article could help you setting up multiple database connections to a single NodeJS server with Sequelize. If you have any questions, feel free to ask them in the comment section.

Pdf2gerb: Perl Script Converts PDF Files to Gerber format


Perl script converts PDF files to Gerber format

Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.

The general workflow is as follows:

  1. Design the PCB using your favorite CAD or drawing software.
  2. Print the top and bottom copper and top silk screen layers to a PDF file.
  3. Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
  4. Use a Gerber viewer to double-check the output against the original PCB design.
  5. Make adjustments as needed.
  6. Submit the files to a PCB manufacturer.

Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).

Php how to delete multiple rows through checkbox using ajax in laravel

First thing, we will need a table and i am creating products table for this example. So run the following query to create table.

CREATE TABLE `products` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 `description` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
 `updated_at` datetime DEFAULT NULL,

Next, we will need to insert some dummy records in this table that will be deleted.

INSERT INTO `products` (`name`, `description`) VALUES

('Test product 1', 'Product description example1'),

('Test product 2', 'Product description example2'),

('Test product 3', 'Product description example3'),

('Test product 4', 'Product description example4'),

('Test product 5', 'Product description example5');

Now we are redy to create a model corresponding to this products table. Here we will create Product model. So let’s create a model file Product.php file under app directory and put the code below.


namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
    protected $fillable = [

Step 2: Create Route

Now, in this second step we will create some routes to handle the request for this example. So opeen routes/web.php file and copy the routes as given below.


Route::get('product', 'ProductController@index');
Route::delete('product/{id}', ['as'=>'product.destroy','uses'=>'ProductController@destroy']);
Route::delete('delete-multiple-product', ['as'=>'product.multiple-delete','uses'=>'ProductController@deleteMultiple']);

#laravel #delete multiple rows in laravel using ajax #laravel ajax delete #laravel ajax multiple checkbox delete #laravel delete multiple rows #laravel delete records using ajax #laravel multiple checkbox delete rows #laravel multiple delete

System Databases in SQL Server


In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
