Developing Web Applications on Liferay using ReactJS and Headless API
Alexa Javellana + Maurice James Sepe
2020-09-25 0:30 UTC
The audience will be oriented on 2 main topics; ReactJS portlets and Headless API. We will be teaching them two different methods of deploying ReactJS portlets on Liferay, as well as common errors and how to troubleshoot them. As for Headless API, we will be discussing how to create a headless API module for a service and how we can customize it to support search. To conclude, we will be working with the audience in connecting these two modules into a complete full-stack application (Reservation System).
