JPDB Examples


Getting Started.

  • Prerequisite : Basic understanding of HTML, JavaScript and JSON.
  • Open a developer account by clicking on the link Developer API.
  • You will receive an email with credentials to login into developer dashboard. This credential will be used to connect to JPDB database in your program code.


Using JPDB for HTML Form data - Easiest Way

# How to get the 'connection-token' to connect to JsonPowerDB in your program / code :

  • Login to JPDB API Dashboard .
  • Dashboard -> Tools -> Tokens .
  • Select 'connection-token' option from dropdown.
  • Select and Copy existing connection token (create a new connection token if there is no token) .

# JsonPowerDB - Easiest Way to store and retrieve HTML Form Data

  1. Copy and Paste following HTML form in your IDE / Editor / Notepad etc. Save this in file register.html .
    (This form will not work till you have serverside programming to receive data and process data).
    
    
                                                

  2. Following changes will make this form working, without any serverside programming.
    (Remember : JsonPowerDB has support for Serverless programming to make your code much smaller, easier and faster)
    • Add the following code in '<head>' section:
       
      <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
      <script src="http://login2explore.com/jpdb/resources/js/jpdb-commons.js"></script>
      
                                                          
    • Replace the existing '<form>' tag with the following:
      (Paste your connection token in the value of data-connection-token in this form tag.
      To know more about the syntax of '<form>' tag click here)
      
      <form id="RegisterForm" method="post"
      data-connection-token="your-connection-token"
      data-db-name="MyDatabase" 
      data-table-name="MyUsers"
      data-success-msg="Thanks for Registering"
      data-error-msg="Data NOT submited."
      onsubmit="return insertFormData2JPDB(this.id);">
      
                                                      
    • Open this page in your browser and fill the form and submit, That's it.

  3. Now to see your data goto: Visualize -> JPDB
    • Select 'MyDatabase' database
    • Select 'MyUsers' Relation

Wow!! Congrats!

Your first HTML form is Working without any Serverside programming
Even without Any Sever setup or installation or configuration or deployment
Surprised!! . . . YESsss JsonPowerDB is simplest, fastest serverless database to develop Dynamic Web, Desktop and Mobile applications - Hurray!.

Exploring CRUD

# Create - This session is to practice on how to add HTML form data into database.

  1. You can just start with any of your favorite IDE with a new 'HTML and Javascript' web project.
    or
    Create a new file using notepad / edit / gedit or any of the text editor of your choice.
  2. Copy the following code by clicking on button at the top right of the code block and Paste it in the newly created file.
  3. Find the code var connToken = "connection-token";, modify this with your 'connection-token' taken from JPDB dashboard and save it with any file-name and extenstion '.html'.
  4. Open this file in browser to see the code working. Add few records.
  5. Confirm adding of data by logging into the Developer API Dashboard than click on Visualize option on left navigation.

                                    

Most of the code in the above example is self explanatory. The important points are:

Use of 'jpdb-commons.js' Javascript library to speedup the development.

                                             
                                                <script src="http://login2explore.com/jpdb/resources/js/jpdb-commons.js"></script>
                                            
                                        

Below code snippet defines the JPDB API end point used for manipulating the data i.e. Index Manipulation Language (iml).

                                             
                                                var apiBaseUrl = "http://api.login2explore.com:5577";    // API Base URL
                                                var imlPartUrl = "/api/iml";                           // API End-Point Part URL
                                            
                                        

Variables to be defined with your choice of database name and relation name.

                                             
                                                // TBD Change the dbName and relName with your choice of database name and relation name.
                                                var dbName = "company_db";
                                                var relName = "emp_rel";
                                            
                                        

Following Javascript methods are created to make this example page working.

                                             
                                                
                                                //To Set api base Url so that user can locate its data to baseUrl of another JPDB instance
                                                function setBaseUrl(apiBaseUrl);
                                                
                                                // Send data to JPDB instance for inserting in the give relation for the user database.
                                                function mySave() {... } 
                                           
                                                // Initializes form data to default values 
                                                function resetFormData() {... }
                                           
                                                // Restore form field focus to first field.
                                                function resetFocus() {... }
                                            
                                        

This line will set the apiBaseUrl to the Url which you wants to set.

                                             
                                                setBaseUrl(apiBaseUrl);
                                            
                                        

This line will read the form data and convert it to Json object.

                                             
                                                var formDataInJson = getFormDataInJson($form);
                                            
                                        

Connection token is required to call the JPDB API. Replace 'connection-token' with your connection-token taken from JPDB dashboard.

                                             
                                                var connToken = "connection-token";
