Javascript function with async gets ignored

[danieljurican]

Hi.
I am having problem with minified js files,...
When I use javascript function like below (calling async), it gets ignored by SquishIt. Function is missing from minified version. I am using version 1.0.4 (same is with version 0.9).

example 1:

async function postData(url = '', data = {}) {           
          const response = await fetch(url, {
              method: 'POST', // *GET, POST, PUT, DELETE, etc.
              mode: 'cors', // no-cors, *cors, same-origin
              cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached
              credentials: 'same-origin', // include, *same-origin, omit
              headers: {
                  'Content-Type': 'application/json'
                  // 'Content-Type': 'application/x-www-form-urlencoded',
              },
              redirect: 'follow', // manual, *follow, error
              referrerPolicy: 'no-referrer', // no-referrer, *no-referrer-when-downgrade, origin, origin-when-cross-origin, same-origin, strict-origin, strict-origin-when-cross-origin, unsafe-url
              body: JSON.stringify(data) // body data type must match "Content-Type" header
          });
          return response.json(); // parses JSON response into native JavaScript objects
      }

example 2:

function sweetAlertOpen() {
    (async () => {

        const { value: formValues } = await Swal.fire({
            title: 'Sweetalert title....',
            type: 'info',
...

This is usually an issue with the minifier itself. If you are using the default (MS ajax) you can try using it with yahoo with something like:

Configuration.Apply(iso => iso.DefaultMinifier = new Minifiers.Javascript.YUIMinifier())

or similar. I am not really doing much .net stuff lately but if this doesn't help I can probably get set up in a couple days. You can look at the configuration options available to either minifier as well - maybe just need to set them up to allow async or something. If you find anything about a minimum version of ajax min or yui I will look into what we can do here to support it as well.

Out of curiosity what asp.net etc versions are you using?

(do the above in your startup pipeline somewhere, you can also change at the bundle level using .WithMinifier method)

I am working on
ASP.NET 4 (Web forms project, VB.NET)

Where exactly should I put WithMinifier method,...
I am using bundle now with line:
Bundle.JavaScript().RenderNamed("combojs")

EDIT:
I think I found solution:
Bundle.JavaScript().WithMinifier(Of Minifiers.JavaScript.YuiMinifier).RenderNamed("combojs")

Sorry for the late reply - I could have sworn I sent before. I think this is right but I don't really know VB.net.

I assume this worked for you?
