Prepare for Outsystems Reactive Developer Certification

Learn how client variables store per-user data across pages and how site properties define server-side global constants and toggles, including API endpoints, feature toggles, data types, and security guidelines.

Explore the Outsystems screen lifecycle, including initialize, ready, render, destroy, on after fetch, and on parameter change.

Master data modeling in Outsystems, including entities, static entities, ID auto numbering, and data types; learn one-to-one, one-to-many, many-to-many mappings with referential integrity rules.

Explore logic building in Outsystems, covering screen, client, server, and service actions, form validation, logic flow, and exception handling, with guidance on action types, scopes, and functional outputs.

Create an employee form with name and surname, use a form widget and a default submit button, and rely on built-in validation to enforce mandatory fields and control submission.

Develop mastery of logic flow and exception handling for Outsystems reactive development through dry runs, switch and if conditions, exception types, and handling paths including new and all exceptions.

Master ui design concepts for the Outsystems reactive certification by practicing screen widgets and web blocks, using layouts, styling, and widget basics, with guidance from the Udemy Skill Builder course.

Learn to design UI widgets and web blocks, handle onClick events, and refresh data with parameter changes on a user management screen.

Review on-click actions for buttons and links, including client actions, navigation, and external URLs; compare fetch at start versus on-demand for aggregates; and examine on-after-fetch, web blocks, and on-parameter-change behaviors.

Explore fetch data concepts by building an end-to-end employee and project workflow, including aggregates, where conditions, built-in functions, joins, and data actions. Create sample data and screens.

Explore Outsystems aggregates to join employees with the project junction, using inner, left, and full outer joins, group by, count, and custom attributes like concatenating name and surname.

Explore modular architecture by separating the UI from service modules, exposing entities as read-only and using wrapper actions to create or update surveys, with dependency management. Learn role based security.

Implement role based security in a survey app by creating admin and manager roles, assigning them to users, and conditionally showing the add survey page button to admins.
