How to trigger a javascript transformer to rerun

[doris.l]

Hi,

I am wondering if we can use a javascript query to trigger a javascript transformer to run? I tried transformer.run() and transformer.trigger() in the javascript query, but they both don't work.

Thank you!

Hey doris.I, happy to help with this JS transformers can't be triggered in the same way that a JS query can. JS transformers update when their input variables update and return a value that can then be referenced in your app.

Here are a couple of suggestions for your use case:

1) You could make your JS transformer into a JS query and trigger that query.

2) You could reference transformer.value to get the return value of your JS transformer.

I hope that clears things up for you
