Run at document start

Question

I am writing an extension need to run at document start. I tried placing the code outside appAPI.ready in the extension.js file but it's still running too late. In chrome I use the "run_at": "document_start" option. How can I do the same in my Crossrider extension.

Answer 1

To run code a document start, you inject the script via the background.js code using the [appAPI.dom.onDocumentStart.addJS][1] method. For example:

appAPI.dom.onDocumentStart.addJS({
  js:"alert('hello world!');"
});
