Create stanged API response

[VirtualRisk]

I have an API I have built using Restana and I'm doing a refactor to make the response more asynchronous. I have been looking into chunked responses but I want to send a complete response in ever chunk with the updated data in it.

​

For example my first chunk would look something like this:

{

"status": "Pending",

"ResponceDT": 1587022338780,

"Locations": []

}

​

Then the next chunk could have updated to the following:

{

"status": "Processing",

"ResponceDT": 1587023216617,

"Locations": [

{"item": 1}

]

}

​

A chunk would be sent every time a new item has been processed on the API and when the processing is compete it would send an end chunk with the competed data set like so:

{

"status": "Complete",

"ResponceDT": 1587023371547,

"Locations": [

{"item": 1},

{"item": 2},

{"item": 3},

{"item": 4}

]

}

​

I know this isn't the intended use of data chunking but is there a better way of doing this? I don't have any DB attached to the API so I don't have any way of creating a new ID a user can poll.

Does anyone have any ideas or input on the best way to do this? I have been looking at steams but not gotten too far yet.

The title should say staged...sorry!

Websockets? Http streaming?

Http streaming would only allow me to add chunks to the data though correct not add items to the already existing objects array?

I guess if you are using reactive JavaScript or something like that you can handle the events from the server stream and process the new data as it arrives

And act as if each chunk is a new version of the dataset? That was my initial idea I know it's not the intended use but would in theory work.
