PrimeNG DataTable Lazy pagination (and sorting) and Spring Data Rest (HATEOAS) via Hibernate JPA

We suppose that we have a simple table that contains the products from figure below:

Further, we expose the data from this table via Spring Data REST. So, a request of type: http://localhost:8080/SHPaginating/items/?size=5 will produce a JSON response as below:

Now, we want to use PrimeNG DataTable Lazy to display data using pagination and sorted by item name as below:

And some HATEOAS information that you can use for further implementations:

The complete example is available here. First, you need to run npm install in \SHPaginating\src\main\webapp.  The app is a WAR that can be tested under e.g. Payara.

Using PrimeNG to authenticate via JWT to a container-less RestExpress microservice

We have two container-less microservices defined in RestExpress. The endpoints are:

AuthenticationService - this service respond to:

http://localhost:8587/clients.json - create a new client

http://localhost:8587/jwts.json?apiKey={apikey}&secret={password} - create a new JWT

http://localhost:8587/jwts/{jwt} - verify if a JWT is valid

SecretService - this service needs authentication and it respond to:

http://localhost:8086/secret/{secretid} - send a secret ID to the secret service

In order to run the app:

1. Download, install MongoDB - this is needed for storing the users

2. Start MongoDB and the AuthenticationService as in the README.txt file

3. Start SecretService as in the README.txt file

4. Run npm install and npm start from  the /PrimeNGandRestExpress/primengapp folder

Some screenshots:
