If you’ve ever deployed a web app to a Samsung Smart TV, you know the pain. Connect via sdb, resolve the device name, package the .wgt file with the right certificate, uninstall the old version, install the new one, run it, pray it doesn’t crash. Every. Single. Time.

After 9+ years of doing this across dozens of OTT projects — including platforms serving 80M+ viewers — I finally snapped and wrote a script that automates the entire thing.

I’m sharing it here because I wish someone had shared something like this with me years ago.

What You Need Before Starting

Before the script can do its magic, you need three things set up on your machine and your TV.

1. Install Tizen Studio. Download it from the official Tizen Studio page. You need the CLI tools — specifically sdb and the tizen command-line utility. The script expects them at ~/tizen-studio/tools/. After the base installation, open Package Manager, go to the Extension SDK tab, and install TV Extensions and Samsung Certificate Extension. The full process is described in the Samsung TV SDK installation guide.

2. Create a Samsung certificate. This is the part that trips most people up. You need a signing certificate to package and install apps on a physical TV. Follow the Samsung certificate guide: open Certificate Manager in Tizen Studio, create a Samsung certificate profile (not a Tizen one), authenticate with your Samsung Developer account, and register your TV’s DUID as the target device. Keep the certificate backed up — future updates must use the same author certificate or the TV treats them as a completely new app.

3. Enable Developer Mode on the TV. On the TV itself, go to the Apps panel, open App Settings, and enter the code 12345. This opens the Developer Mode popup. Toggle it on, enter your computer’s IP address, and reboot the TV. After restart you’ll see “Develop Mode” at the top of the Apps panel. The full walkthrough is in the Samsung device setup guide.

Also required: Java 8. Tizen CLI tools still depend on Java 8, not newer versions. On macOS, install it with brew install --cask temurin8. The script automatically detects and switches to Java 8 for the session, so it won’t mess with your system Java.

What the Script Does

The script gives you an interactive menu powered by gum (a terminal UI toolkit that it auto-installs if missing). You get 8 options:

1. Run All Steps — connect, resolve device, package, uninstall old version, install, and run. One selection, done.
2. Connect to TV — establishes sdb connection to your TV’s IP.
3. Resolve device name — reads the device identifier from sdb, needed for all Tizen CLI commands.
4. Package app — signs your build directory as a .wgt file with your certificate. Handles filename sanitization automatically.
5. Uninstall app — removes the existing version from the TV (gracefully ignores if not installed).
6. Install app — pushes the .wgt to the TV.
7. Debug app — launches a debug session and forwards the debug port so you can attach Chrome DevTools.
8. Run app — launches the app in non-debug mode.

You can also pass a pre-built .wgt file directly, and the script skips the packaging step entirely.

Config Persistence: Set Once, Deploy Forever

On first run, the script asks you four things: TV IP address, certificate name, package ID, and the path to your build directory (or .wgt file). The package ID comes from your project’s config.xml — it’s the combination of the tizen:application package attribute, in the format AbCdEf1234.MyApp. The script saves all of this to ~/.tizen_deploy_config, so every subsequent run just works — no re-entering values.

Working on a different project or switched TVs? Run the script with --clear-config to reset everything:

./tizen_deploy.sh --clear-config

This wipes the saved config and prompts you fresh.

The Full Script

Here’s the complete source. Save it as tizen_deploy.sh, make it executable with chmod +x tizen_deploy.sh, and run it.

How to Debug Your App with Chrome DevTools

One of the most useful features of the script is remote debugging. Here’s how to connect Chrome DevTools to your app running on the TV.

Step 1: Close the app on the TV. If the app is already running, close it first. The debug session needs to launch the app itself — it won’t attach to an already running instance.

Step 2: Run the debug command. Launch the script and select “Debug app + forward port” from the menu. The script will output a port number — copy it.

Step 3: Open Chrome DevTools for devices. In Chrome, go to chrome://inspect/#devices. Make sure “Discover network targets” is checked, then click Configure…

Step 4: Add the debug port. In the Target discovery settings dialog, add localhost:{port} where {port} is the number the script returned. Click Done.

Step 5: Inspect. Your TV app should appear under Remote Target. Click inspect on the first item in the list — a full Chrome DevTools window opens, connected to your app on the TV. You can inspect DOM, debug JavaScript, profile performance, and see network requests just like you would on a regular web page.

Important Notes and Limitations

A few things to keep in mind:

• Tested on macOS. The script has platform detection for Linux and Windows (Git Bash), but I’ve only battle-tested it on macOS. Linux should work with minor adjustments. Windows via Git Bash/MSYS is experimental — your mileage may vary.
• Java 8 is mandatory. Tizen CLI refuses to work with Java 11+. The script handles this by temporarily switching JAVA_HOME for the session only — your system Java stays untouched.
• Certificate issues are the #1 problem. If install fails with a signing error, check three things: the certificate profile name must match exactly, the TV’s DUID must be registered in the distributor certificate, and the certificate type matters — you need a Samsung certificate (not Tizen), and the privilege level must be correct (Partner for apps using privileged APIs, Public for basic apps).
• gum is auto-installed. The interactive menu uses gum from Charm. If it’s not installed, the script installs it via Homebrew (macOS), apt/dnf/pacman (Linux), or asks you to install it manually (Windows).
