Missing generic for progress object

[kibertoad]

It would be great if it was possible to provide generic for Job progress object

[manast]

@kibertoad do you have an example on how you would like it to look like?

[kibertoad]

Currently Job is typed like this:

export declare class JobPro<DataType = any, ReturnType = any, NameType extends string = string> extends Job<DataType, ReturnType, NameType> {

I would expect this to look something like

export declare class JobPro<DataType = any, ReturnType = any, NameType extends string = string, ProgressType = number | object> extends Job<DataType, ReturnType, NameType, ProgressType> {

Currently numbers or objects are supported, and it would also be great to narrow it down on a generic level to what is actually used and not have to do safe guards inside the code.

I see. This would be useful in standard BullMQ as well.
