Spring Boot + Angular: Pagination example

#angular #springboot #javascript #webdev

In this tutorial, I will show you how to build a full-stack Pagination (Angular + Spring Boot) example on Server side. The back-end server uses Spring Data and Spring Web for REST APIs, front-end side is an Angular 11/10/8 App with HTTPClient.

Pagination with Angular & Spring Boot example

Assume that we have tutorials table in database like this:

We need to export APIs for pagination (with/without filter) as following samples:

/api/tutorials?page=1&size=3
/api/tutorials?size=5: using default value for page
/api/tutorials?title=data&page=1&size=5: pagination & filter by title containing 'data'
/api/tutorials/published?page=2: pagination & filter by 'published' status

This is structure of the result that we want to get from the APIs:

{
    "totalItems": 12,
    "tutorials": [...],
    "totalPages": 3,
    "currentPage": 1
}

Our Angular app will display the result with pagination:

You can change to a page with larger index:

Or change page size (quantity of items per page):

Or paging with filter:

Full-stack Architecture

We're gonna build the application with following architecture:

Spring Boot exports REST Apis using Spring Web MVC & interacts with Database using Spring Data.
Angular 11/10/8 Client sends HTTP Requests and retrieve HTTP Responses using axios, shows data on the components. We also use Angular Router for navigating to pages.
