As Glide Record is on server side why Glide form and Glide User works on client side ??

Hi @harshshree7 ,

GlideRecord: GlideRecord is a special Java class (GlideRecord.java) that can be used in JavaScript exactly as if it was a native JavaScript class.

• is used for database operations instead of writing SQL queries.
• is an object that contains zero or more records from one table. Another way to say this is that a GlideRecord is an ordered list.

GlideUser in Client Script

The GlideUser API provides methods that access information about the current user and current user roles. Using this API avoids the need to use the slower GlideRecord queries to get user information.

GlideUser methods and properties are accessed through a global object (g_user) that is only available in client scripts.

This API:

• contains name and role information about the current user.
• is typically used in client scripts and UI policies but is also found in UI actions that run on the client.
• cannot be used in business rules or UI actions that run on the server.

Hi @harshshree7 ,

Sorry but it's not "why" on server side or client side.

That's the official instance recommended methods designated and defined to work for Server side and Client side respectively.

@harshshree7 

that's how ServiceNow has designed it.

GlideRecord does work in client side but has limited capabilities, not all GlideRecord methods which are supported in server side work in client side.

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi,

There are a whole lot more APIs from ServiceNow that you can use. And they all have different purposes and functionality, and, as you mentioned, they are often used on different parts, as server-side or client-side.
