NW & Electron Limitations

[Ronny]

NW

User-Agent in Background Script not correctly applied

In newer versions of NW, the User-Agent in the background script (navigator.userAgent) defaults to Node.js/21.
This results in always triggering the restart notification when assigning a User-Agent, even when the real User-Agent didn't changed.

Affected:

haruneko/app/nw/src/ipc/RemoteProcedureCallContract.ts

Line 27 in 1874bcf

 if(userAgent !== navigator.userAgent) { 

New Browser Window is inaccessible

When using a browser window to fetch a request (e.g., bypass CloudFlare) the window may be empty (no DOM or JavaScript access) or may have the same content as the application window.

Affected:

haruneko/web/src/engine/platform/nw/FetchProvider.ts

Line 215 in 6ffcea9

 if(!win.window || nw.Window.get().window === win.window) { 

MediaSource not supported

When initialising a video element based on media source to stream frames, NW.js seems not to support the necessary MediaSource type. Also audio is missing in normal embedded MP4 video streams.
