Is Brython is planned to use Fetch API ?

[BobSquarePants]

Hi,

According to https://developer.mozilla.org/en-US/docs/Glossary/XMLHttpRequest

Fetch API is the modern replacement for XMLHttpRequest.

ok, right... There is no explanation why..

I beleive the Brython module browser.ajax use XHR and it work quite well.

But would there be an advantage to use the Fetch API instead of XHR ? and is it planned to be implemented in Brython ?

Thanks :)

You can use fetch() like any other function in the global Javascript namespace:

from browser import window, aio

async def fetch(url):
    resp = await window.fetch(url)
    print(await resp.text())

aio.run(fetch('test.html'))

Thank you @PierreQuentel ,

I will give it a try.. but will fetch API will perfome better/faster that XHR ? because I can't found any documentation about it.

Thanks.

It is documented like for other web technologies on the MDN site.

I don't think it was designed for performance, but (quoting the MDN site) as a "a more powerful and flexible replacement for XMLHttpRequest.".
