TypeScript GlideRecord's Type Parameter

[UIB Whisperer]

Hey there!

I've converted an existing application still in development to a NowSDK version of it and I've ran into a problem when it comes to declaring the type parameter of the GlideRecord class. I want to be able to dot-walk into the GlideElement objects of the GlideRecord one like in the example below which I've invented.

import {
	GlideAggregate,
	GlideDateTime,
	GlideRecord,
	GlideScopedEvaluator,
} from '@servicenow/glide'

export default class AccessRequestAPI {
	endpoint_gr: GlideRecord<HTTPMethod>
	rest_message_gr: GlideRecord<RESTMessage>
	constructor(endpoint_gr: GlideRecord<HTTPMethod>) {
		this.endpoint_gr = endpoint_gr;
		
		this.rest_message_gr = this.endpoint_gr.rest_message.getRefRecord(); // Returns String -> Error cause not a valid type
	}
}

 I know I can use the "any" type and TypeScript will hide the message when the transpiler is set to not strict but having it as strict is a best practice and I want to know if there's a way that I'm not seeing to achieve this.

Thanks in advance!

Hi @UIB Whisperer,

We donot support dot-walking for table fields or other types in GlideRecord yet.

As of now, the sole purpose of the types in "@servicenow/glide" package is to provide intelli-sense in the IDE and to make modules aware of the Glide APIs available at runtime.

And types for "RestMessageV2" are available under the "sn_ws" namespace, which can be imported in modules using

import { RestMessageV2 } from "@servienow/glide/sn_ws"

Thanks

Hey @Venkat79, thank you for your response. I did figure out the module where those are exported but could not figure out the part on how to implement a typed GlideRecord. Is this last one going to be addressed? If so, anytimeline?

Hi @UIB Whisperer, Yes we will be adding support for Typed GlideRecord but I won't be able to provide a timeline. Sorry.
