Editing Multiple Feature Layers in Esri JS API 4

Question

Howdy! I'm trying to figure out how to edit multiple feature layers within the Esri JS API 4 ecosystem. I have the editing of a single feature layer nailed down: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no">

But when I add a second Feature Layer and attempt to put an if/else route in the JS, I'm not getting any luck. Even more simply, when I add a second FeatureLayer the promise that is issued runs into an issue handling multiple layers. The least elegant solution I can think of is to literally just duplicate the functions and promise-strings for the second FeatureLayer, but that seems pretty heavy-handed. If anyone has any samples or insight into editing multiple Feature Layers in the Esri JS API 4 environment, I'd be really grateful to see 'em!

I apologize for the scatterbrainyness of the last paragraph; what I meant to convey way this:

the workflow of editing in this app is as follows: 1. users selects either ButtonA or ButtonB.      1a.ButtonA allows for editing of feature service A.

1b. Button B allows for editing of feature service B.

2. Once a user clicks a button, the two buttons become disabled from being clicked again until a feature has been added.

3. Once a button has been clicked, the user can draw a single polyline graphic ONLY for the corresponding feature ( ie if a click ButtonA I can only create a single Polyline feature against Feature Service A.

4. User clicks “done” and the edits are saved and the two buttons become clickable again.

I meant to convey that users will only be editing one feature at a time against a single feature service, but they have the option to choose which feature service to choose.

The allRequests is an array. So you would push one request at a time into the array. Then, when all done, you would process all requests simultaneously. ie. You can edit Feature from layer 1. Then, edit another feature from layer 2. Then, when ALL of them are done, you would process them all (so you'll end up with an array of responses.).
Im not following your last paragraph.

Hey Karen!

im still getting acquainted with JS (and especially the Esri JS API), so I apologize for potentially rudimentary clarifications that are forthcoming

1. The allRequests.push component essentially creates a single “entry point” to execution by extracting the Object ID and passing that as a string parameter to the subsequent functions to specify the Object on which to create the edits — is my understanding right on?

2. The if-statement component checks if any events have been created (if so, there length would be > 1 and thus trigger the nested functions). This is conceptually Pythonic so this function makes more sense to me (but the asynchronous callback / promise chains are still a bit challenging   ).

One more point of to make sure we’re speaking the same language; I’m trying to edit one feature at a time from one feature service. However, I want users to choose which feature service they’re editing (either street closures OR street detours). Each editing session will be contained to a single feature of a single feature service. My issue was adding another editable feature service (then converting to a layer) without effectively rewriting all my promise chains.

Does se that make sense?
