The purpose of this post is to extend the image provided by Liferay PaaS to include a custom module — ngx_brotli, a widely-used compression module that improves web performance by reducing response sizes. While Liferay PaaS offers a robust and opinionated platform for deploying DXP-based solutions, it also introduces constraints that can make low-level customizations like ...

Introduction You probably read the title of this article and thought, "finally, my friendly URL problems are solved!". And in part, you're right! The idea here is to share a "cake recipe" to achieve a crucial goal for many SaaS portals built on Liferay: removing or hiding the notorious /web from your sites' URLs. This article is based on a real-world use...

Introduction Goodbye MySQL? No, don't worry, Liferay isn't dropping support for MySQL, don't start panicking just yet. Liferay has been transitioning new PaaS and new/existing SaaS systems from MySQL to PostgreSQL 16, so the cloud-based systems are saying goodbye to MySQL and saying hello to PostgreSQL... This blog post isn't really about announcing the change, I ...

Many weeks ago I blogged about how I could no longer add images to blogs and this was preventing me from publishing some entries I had which needed screen shots... We have since fixed that issue, but I'm not sure I shared what happened. As it turns out, on liferay.dev we were following security best practices by creating and configuring a Role with necessary permissions,...

Virtual Instance in Liferay 7.4 In this Blog Today we will discuss about the Virtual Instance in Liferay 7.4 version. What is virtual Instance: - As we know that when we install a new Liferay DXP setup so it gives us some configuration like users, sites, organizations, roles and instance setting etc.  If you want to create a new installation like this and ...

In my last blog, Creating a React Client Extension, I basically built a React-based SPA that was hosted on Liferay. And I got to thinking that we really aren't sharing just how great Liferay is to host Javascript-based SPAs in any framework, be it React, Angular, Vue.js or others. So I thought I'd take some time to share with Javascript developers some reasons why...

Just a short one today... I happened to be researching Object Validations and I saw an interesting note posted here: https://learn.liferay.com/w/dxp/liferay-development/objects/creating-and-managing-objects/validations/adding-field-validations#using-groovy-validations To quote (in case the content gets changed): IMPORTANT As of DXP 2024.Q2/Portal 7.4 GA120,...

Introduction I was recently asked whether it is possible to migrate from HCL DX™ to Liferay DXP. I think the expected response was "no", because they seemed shocked when I said it was possible. Let's ride along with Mr. Peabody and Sherman in the Wayback Machine to review some history and understand why migration is possible... Set the Wayback Machine for...

Introduction In my recent blog, Introduction to Liferay Objects, I used Objects and Liferay OOTB facilities to have a list of Course Registrations and UI interfaces for submitting a new Course Registration, listing them, and for admin users the ability to approve or deny them. It worked well, but it didn't handle maybe some expected requirements. For example, the...

Introduction So I've been working on my Objects Rule! series and have been working on an app I plan on showing off soon, but I realized that there is probably a gap explaining, well, how do you get started? I mean, it's one thing to go and check the client extensions sample repo here: https://github.com/liferay/liferay-portal/tree/master/workspaces/liferay-sample-workspace,...

Introduction In a recent blog, Intro to Liferay Objects, I created a new application for the Masterclass site for submitting and approving course registrations entirely using OOTB features of Liferay, specifically Objects for the data store, and Fragments for the presentation (form fragments and collection display fragments and Masterclass fragments). This approach...

Introduction Wow, I've blogged about Liferay Objects a lot lately. Talked about them too. Also am working on developing materials for learn.liferay.com about Objects. But one thing I haven't seen is an introduction to objects suitable for long-time Liferay users or new Liferay users, so I thought I'd take time to write one (since my blog ideas well seems to be...

Introduction I was recently in a meeting reviewing some FreeMarker templates that were extracting web contents using a structure, parsing and processing the data, and rendering an output. Basically the implementation was kind of the classic or "legacy" way of doing specialized presentation of structured contents in Liferay. In this case they had a Carousel...

Introduction GitLab is a web-based DevOps lifecycle tool that provides a Git repository manager, continuous integration (CI), continuous delivery (CD), and a range of collaboration and project management features. It is used to manage the software development process, facilitating collaboration among team members, version control with Git, and automated build and deployment...

Introduction Kubernetes, commonly referred to as K8s, is an open-source system designed for automating the deployment, scaling, and management of containerized applications. It is a robust and flexible solution for deploying Liferay, facilitating scalability and monitoring. While creating a Liferay cluster on Kubernetes is not overly complex, there are certain nuanced...

Introduction So I was recently working with a team that was completing an upgrade assessment for a client wanting to upgrade from 7.2 to 7.4. A big chunk of the work in upgrading the client was going to be taken upgrading the themes. The client had one primary theme which contained the common style rules, but they also had 8 "child" themes, based upon the primary,...

Setting Up Glowroot on LXC-SM, Liferay Cloud Fabian's blog illustrates Glowroot setup in an on-premises environment here. Now, let's outline the steps for integrating Glowroot within Liferay's LXC-SM cloud infrastructure. Key Components and Configuration Files: LCP.json: This pivotal file, residing in the 'liferay' directory, ...

This article explains how to deploy npm packages bundled with webpack that export and import stuff through the standard ECMAScript modules feature. This is a sequel of the Moving from AMD to Browser modules in Liferay DXP blog post, so it’s recommended reading that if you haven’t done so already. Why use webpack with ES modules? The main goal of using webpack and ES...

This article explains how to leverage the new ECMAScript modules feature (from now on will be referred to as ESM), Custom Element and Import Map Entry client extensions in Liferay DXP to achieve the same goals possible in the AMD architecture (and more). The motivation for this article is that, with the new ESM/client extensions architecture, the things we were used to doing with...

Introduction So if you really want to set off a firestorm with geeks like myself, step into the group and say "VI is better than Emacs!" Be sure to turn and walk away quickly or you might find yourself included in the tussle. Another way to set off a firestorm is to mention ChatGPT. Some like it, some hate it. I'm not really going to cover whether it is...
