🚀 Introduction

If you have worked with Liferay earlier, you probably remember the pain of Service Builder—writing XML, generating code, deploying modules, and managing OSGi.

In my experience working on Liferay-based portals, even a simple CRUD feature used to take hours or sometimes days.

But with Liferay 7.4, everything changed.

Liferay Objects is a powerful low-code feature that allows you to create database entities, APIs, and UI directly from the browser—without writing backend code.

📌 What are Liferay Objects?

Liferay Objects allow you to build applications directly from the Control Panel UI.

• Create database tables
• Define relationships
• Configure UI layouts
• Automatically generate REST APIs

Once published, Liferay automatically creates:

• Headless REST APIs (/o/c/{objectName})
• GraphQL APIs
• Permission management
• UI interfaces

💡 Real Insight: I used Liferay Objects to quickly build an internal ticket system, and it reduced development time by almost 70%.
