Seeking a Complete Learning Roadmap to Master ServiceNow Client-Side and Server-Side Scripting

Hello ServiceNow Community! 👋

I am currently learning ServiceNow development, and my goal is to build strong knowledge of both Client-Side Scripting and Server-Side Scripting, starting from the basics and progressing to advanced concepts.

I want to understand not only the syntax but also how to write scripts, solve real-time business requirements, debug errors, and implement scripting solutions in practical projects.

I would appreciate guidance on the following topics:

  • Client-Side Scripting: Client Scripts (onLoad, onChange, onSubmit, onCellEdit), GlideForm (g_form), GlideUser (g_user), and UI Policies.

  • Server-Side Scripting: Business Rules, Script Includes, GlideRecord, GlideAggregate, GlideSystem (gs), and Scheduled Jobs.

  • Client-Server Communication: GlideAjax, AbstractAjaxProcessor, and asynchronous server calls.

  • Practical Learning: Real-time scenarios, coding exercises, debugging techniques, and best practices.

  • Learning Roadmap: The correct order to learn these concepts and the resources recommended for beginners.

If you have any recommended tutorials, documentation, hands-on exercises, or project ideas, please share them.

My goal is to become confident in writing and troubleshooting ServiceNow scripts independently and eventually handle real-world development requirements.

Thank you for your guidance and support!

Hi Harshal

My suggestion is to learn in this order

 

  • JavaScript fundamentals
  • Client Scripts, g_form and UI Policies
  • Business Rules script part
  • GlideRecord and GlideAggregate
  • Script Includes
  • GlideAjax
  • Scheduled Jobs and debugging.

It will be good to Start with ServiceNow official hands-on learning resources:
old but still good : Learn JavaScript on the Now Platform: Overview
and then Scripting Fundamental

focus highly on practising every concept in a PDI and solve real like business scenarios.
