Implement and Configure for WebOs LG TV Apps in Windows

1. Go to on browser and Download WebOs CLI from this link WebOsCLI

2. Now, open the command prompt as administrator and run this command

echo 
%LG_WEBOS_TV_SDK_HOME%

2.1 If the environment variable LG_WEBOS_TV_SDK_HOME already exists, its path will be output. Now, we have to configure the environment variable. Before doing that, create a folder and name it webOS_TV_SDK at your desired folder and extract the WebOs CLI into the folder that you just created.

2.2  Now, open the command prompt and use this command to set the LG_WEBOS_TV_SDK_HOME variable to the parent directory of the CLI

setx /m LG_WEBOS_TV_SDK_HOME "path-where-created-folder-is-present\webOS_TV_SDK"

2.3  Now, run this command to set the WEBOS_CLI_TV variable to the bin directory of the CLI

setx /m WEBOS_CLI_TV "%LG_WEBOS_TV_SDK_HOME%\CLI\bin"

2.4  Now, run this command to set the bin directory of CLI to the PATH variable

setx /m PATH 
"%PATH%;%WEBOS_CLI_TV%"

2.5   Now, you have to restart the computer or laptop so that configurations should work properly

After Restart

Now, we have to add the path of the WebOs CLI so that its command should work. To do that, open environment variables go to Path of System Variables and add the path to the bin folder inside of the CLI folder that we extracted into the webOS_TV_SDK folder.
Like this –

2.6  Once it’s done, you are now able to run the WebOs cli commands in your system.
2.7  Verify the installation by running this command

ares -V

It will generate output like this:

webOS TV CLI Version: 1.12.4-j27
