event callback - how to listen to before/after events

[danielnc]

I have a couple of places where I am using request.js and I want to globally opt-in to specific before/after requests start/complete so I can give user proper feedback, showing progress-bar

Similar to how turbo uses progress bar for long running requests but I couldn't find a way to listen to specific events

does request.js supports listening to before/after events?

I know there is an example for withPgoress wrapping the function, but I want to use that globally instead of having to call it on every single request.js call

@danielnc request.js does not emit any before/after events; You can get exactly that behavior by doing what readme https://github.com/rails/request.js#before-and-after-hooks suggests doing. Note the last function that is exported

export function get(url, options) {
  const request = new FetchRequest("get", url, options)
  return withProgress(request.perform())
}

^ In the JS files, you want to import and call this get function instead the one request.js exports.
