Hello

Forge components in OutSystems are developed using a variety of languages and technologies depending on the type of component and its intended use. Here’s a brief overview of the languages and how they are applied: JavaScript: For client-side logic, dynamic interactions, and custom functionality

.jQuery: A popular JavaScript library used for simplifying HTML DOM manipulation, event handling, and AJAX interactions.JavaScript/jQuery: Similar to reactive applications, used for client-side scripting and enhancing user interfaces.C# (in Integration Studio): Used to create custom server-side actions, extensions, and integrations with external systems.

SQL: For direct database interactions, often within advanced queries and aggregates.

The combination of these languages and technologies allows for the creation of highly customizable and functional Forge components in OutSystems. Understanding how and where to apply each language will significantly enhance your ability to develop robust applications within the OutSystems platform.

i hope it's help you

Hi,

It depends on the application type:

Traditional Web App: You code in OutSystems, javascript/html/css, jQuery

Reactive Web App & Library: You code in OutSystems, javascript/html/css, ReactJs 

Extensions: C#

The OutSystems Visual Language Model generates C#, javascript/html/css
