Allow cancellation during file download with AbortController

[muuvmuuv]

Feature Request

Plugin

• Filesystem

Description

I would like our users to allow cancelling file downloads. We download a lot of files in batches in a queue and currently the UX is not very good because the running batches of files in background block the WebView rendering in Android. The user must wait for all files in the batch to be download.

Platform(s)

• iOS
• Android
• Web

Preferred Solution

Use AbortController to allow cancellation per Spec.

Compatibility seems to be in your range: https://developer.mozilla.org/en-US/docs/Web/API/AbortController#browser_compatibility

Alternatives

Callback or something.

This limitation affects user experience significantly. Could someone please take a look at this issue? Also, if possible, could you provide an estimate on when we might expect this feature to be implemented?

Many thanks for your ongoing efforts and support.

Hey all - we have a scenario where users have no way of cancelling large downloads without closing and opening the app. This is really bad UX.

Is there anything I can do to help move this along? I'm happy to dig into the plugin source if need be.

I'd love to see this too — downloadFile should be cancelable.

edit: I found a plugin that seems to support, https://github.com/AlwaysLoveme/capacitor-plugin-filedownload

I'd need to have this too

Hey everyone, downloadFile has since deprecated in the filesystem plugin, there is now a @capacior/file-transfer, unfortunately it does not provide a way to abort downloads either.

I shall close this issue, please refer to https://github.com/ionic-team/capacitor-file-transfer/issues/7 for updates / tracking.

Thank you!
