    jDB Net

    Hello, welcome to the documentation of jDB Net. This module is focused on making an efficient database with real time connection.

    Area Quick Description
    Introduction Have a basic Idea of the module.
    Structure Have an idea of how the database looks.
    Getting Started Get started using the module.
    Server Set-up How to set-up the Server.
    Client Set-up How to set-up the Client.
    Usage How to use the Module.
    Examples Examples using this Module.


    This module have two sides. The server side that will hold the database, listen and validate requests. and the client side that will send requests to get, add, or delete data. There are permissions based on keys the server makes (or you). This permissions include read (Read the data), write (Add items, change their value), and manage (Delete whole rows and add news). And you can use the same computer as a server and client.


        "item": "value"

    Structure the JSON code below is a valid in this database. There are collections. Inside those collections there are items that cointains values.

    collection => item => your info
    // Example can Be
    user => yaxeldragon => subscription => premium
    // It supports JSON so you can add as much as you want.

    Is fine if you don't get this now. In the practice you will understand it more.

    Getting Started

    To start using this database type the following in your console

    npm install jdb_net

    Wait until installed. Then import the module in your project by typing the following in your project

    const jDB_Net = require('jdb_net');

    Server Set-up

    To set up the server is very easy. First construct the client like this

    // Imports
    const jDB_Net = require('jdb_net');
    // Set-up the Server
    const server = new jDB_Net.server({
        verbose: true, // Shows ALL Activity. (optional) (default: false)
    • Note : The JSON inside the constructor is totally optional. doing new jDB_Net.server(); would work, and have default values.

    Then make the server listen for requests like this

    server.listen(8080); // 8080: Is the PORT

    Once you run this code it will give you a LOGIN KEY with default read: true, write: true, manage: false. You can make more going to etc/keys.json file and following the template.

    • Note : Make sure you have READ, and WRITE, and the IP of the machine you are running the server on.

    Client Set-up

    To set up the client it is slightly more complicated, and you need the IP, of server, and PORT, and LOGIN KEY. In this example the IP will be, the port will be 8080, and the key will be jdb (Not Recommended)

    First construct the client like this

    // Imports
    const jDB_Net = require('jdb_net');
    // Set-up the Client
    const client = new jDB_Net.client('', 'jdb', {
        verbose: false // Shows ALL Activity. (optional) (default: false)
    • Note : The JSON inside the constructor is totally optional. doing new jDB_Net.client('', 'jdb'); would work, and have default values.

    Then connect by doing

    client.connect().then(() => {
        // All your code here.
        // (jDB is made so it waits for the server to connect to execute this.)
        [ ... ]


    Command Action
    client.createCollection('collection'); Creates a Collection.
    client.collectionExists('collection'); Checks if a collection Exists.
    client.createItem('collection', 'item/s'); Creates an Item inside a Collection.
    client.fetch('collection'); Returns items inside a Collection.
    client.setItem('collection', 'item', 'value/s') Sets a value to an existing Item.

    Create Collection

    client.connect().then(() => {                // Connect
        client.createCollection('collection');   // Create Collection

    Simply creates a new Collection.

      • Manage

    Collection Exists

    client.connect().then(() => {                // Connect
        client.collectionExists('collection').then(exists => {
            if ( exists == true ){
                console.log('Collection Exists') // Logs "Collection Exists"
            } else {
                console.log('Collection Doesn\'t Exists') // Logs "Collection Doesn't Exists" 

    Checks if a collection Exists

    • Needed Permissions :
      • Read

    Create Item

    client.connect().then(() => {                           // Connect
        client.createItem('collection', 'item');            // Add a single Item
                      // OR
        client.createItem('collection', ['item', 'itemB]'); // Add multiple Items

    Adds an item inside a collection.

    • Needed Permissions :
      • Write


    client.connect().then(() => {                           // Connect
        client.fetch('collection').then(data => {
            // If there are ITEMS you can do :

    Looks for all items inside a collection and return it as JSON

    • Needed Permissions :
      • Read

    Set Item

    client.connect().then(() => {        // Connect
        client.setItem('collection', 'item', 'value');
            // OR to expand more the Possibilities
        client.setItem('collection', 'item', {
            subitem: 'another value, Wow!'

    Set a value to an existing item. (It creates It as well)

    • Needed Permissions :
      • Write


    Creating and Displaying Data

    client.connect().then(() => {
        client.collectionExists('users').then(exists => {      // Checks if Collection Exists
            if (exists == true) {                              // ---------------------------
                client.createItem('users', '001');             // Create Items '001' Item in 'users' collection.
                client.setItem('users', '001', {               // Set values to '001' item in 'users' collection.
                    plan: 'premium',                           // |  This value
                    expires: '12/12/2012'                      // |_ And this value
                });                                            // ---------------------------
                client.fetch('users').then((users) => {        // Fetch all items in 'users' Collection.
                    console.log(users['001'].plan);            // Logs "premium"
