Ionic 4 ngx-datatable Tutorial Basic


This sample app tutorial provides step-by-step instructions that will walk you through the process of developing a simple ngx-datatable Ionic 4 application.

Downloads and Resources

You can also download the basic Ionic 4 DataTable app backup file to import it to your app. In this case, the database and the database service will be imported automatically.



There are some important pre-conditions to make your app work: you will need to create a database and a related database service; please, check Steps 1 and 2 for details.

Step 1: Creating Database

Let's start by creating a database where the data will be stored.

  1. Co to the Databases tab and create a new database, let's name name it BooksDB.
  2. Create a collection with Name: BooksList.
  3. Add two columns of String type: Title and Author.
  4. Add a column with Name: Year and type : number.
  5. Add another column: Image of the file type with uploading all the needed images.

  • You might like to get more information from Database documentation.

Step 2: Creating Database Service

To create a new database service:

  1. We need to, first of all, create a new Ionic 4 app (blank).
  2. Now, we can proceed with creating a service for our database. Click CREATE NEW > Database Service.
  3. In a new window, select the database we have just created, select the List service of the BooksList collection (expand it first) and confirm import:

  1. Select Success Mapping and, in the mapping editor, click Expand all for both Service response and Page. We should relate our service with the DataTable component and bind the service scope with the rows of our DataTable as well as the columns of the table. To do it, create the below mapping and save:
Service **Success** mappingService **Success** mapping

  1. Go back to the DESIGN panel and select DataTable.
