I developed a web application with ReactJs and installed the same application as a tizen tv widget. I am establishing longpolling connection with SignalR on remote server. It works on version 5.5 of the browser and emulator, but not 4.0 and 4.5 on a real device. In versions 4.0 and 4.5, it sends a request for connection, but I do not get an error. I don't see a problem with Tizen and Samsung permissions. It is stated in the documents that 4.0 and above support socket connection. I couldn't tell the difference between the two versions.

Tizen configs:

<?xml version="1.0" encoding="UTF-8"?> <widget xmlns:tizen="http://tizen.org/ns/widgets" xmlns="http://www.w3.org/ns/widgets" id="http://yourdomain/ReactEmpty" version="0.2.1" viewmodes="maximized">

<access origin="*" subdomains="true"/>
<tizen:setting screen-orientation="landscape" context-menu="enable" background-support="disable" encryption="disable" install-location="auto" hwkey-event="enable"/></widget>

Build methods:

"tizen-build": "rm -rf build && craco build && cp tizen/* build && tizen build-web -- build && tizen package -t wgt -s thisSignatureName -- build/.buildResult",
"tizen-deploy": "tizen install -n ReactPanel.wgt -- build/.buildResult",
"tizen-full-deploy": "yarn tizen-build && tizen install -n ReactPanel.wgt -- build/.buildResult"

I need your good ideas. Thnx.

  • You had any succes in solving this issue? Have an angular project using websockets and on TV it works while in Developper mode, but when I switch to "normal" TV mode the tizen web application will freeze/hang :( – ionescu77 Aug 31 '22 at 13:34
  • Sorry, I couldn't find a solution and closed the project. I hope you can provide a solution. – newbie here Sep 04 '22 at 20:14

Try to build with Tizen studio instead, a debug build would help to identify the problem immediately with the inspector

  • Unfortunately I don't have any idea how to compile an external project with Tizen Studio. Do you have a suggestion for a solution for this? – newbie here Mar 03 '22 at 00:11
  • Open Tizen studio, and create a new project there, that will give you the proper boilerplate to run on a TV, then open the project folder from Tizen studio, paste your web app inside there and that's it – Ali Sao Mar 13 '22 at 15:18
  • I will try, thanks. – newbie here Mar 17 '22 at 08:25
  • Opening an Angular project in Tizen Studio takes ages and most of the time crashes, as tizen studio proceeds to check and compile every node package dependencies. :( – ionescu77 Aug 31 '22 at 09:25
  • I had similar problem. So I couldn't debug. – newbie here Sep 04 '22 at 20:16
