CLI Developer Guide

This guide will take you through the app development process for webOS TV with CLI from creation to debugging. The process comprises creation, packaging, installation, launching, and debugging of an app, and if you are to use webOS TV Simulator, packaging and installation will not be necessary.

Create a web app

The first step is creating a web app using the ares-generate command from a template. There are two web app templates available.

• Basic web app template: A template of a basic web app that displays the “Hello World” message on a screen
• Hosted web app template: A template of a hosted web app

The webOS CLI further provides templates for JS services, config files, etc. For the list of all available templates, see App Templates, or use the following command.

ares-generate --list

Create a basic web app

The basic template provides a “Hello World” web app with the minimum essential files. This template is useful if you are to use other UI frameworks.

Execute the following command to create a basic web app into the./sampleApp directory.

ares-generate -t basic ./sampleApp

The following table lists the files of a web app that the template provides:

Create a hosted web app

The hosted_webapp template provides a hosted web app that contains a redirect URL with the minimum essential files.

Execute the following command to create a hosted web app into the ./sampleApp directory.

ares-generate -t hosted_webapp ./sampleApp

The following table lists the files of a hosted web app that the template provides:

Create a JS service

The js_service template provides a sample JS service running as a background service on webOS TV. The sample JS service responds to simple messages for a service request.

Execute the following command to create a JS service from the template to the ./sampleService directory.

ares-generate -t js_service ./sampleService

The following table lists the files of the sample JS service with the description:

Create an appinfo.json file from template

The webappinfo template provides anappinfo.json file with sample values. If you are building a new web app without a template or using the existing web app which was not made from a template, you should add the appinfo.json file into your app. This file holds the app’s name, ID, app type, icon image, and the main page information.

Execute the following command to create an appinfo.json file from the template into the sampleApp directory.

ares-generate -t webappinfo ./sampleApp

The following is the sample appinfo.json file created from the template.

{
  "id": "com.domain.app",
  "version": "0.0.1",
  "vendor": "My Company",
  "type": "web",
  "main": "index.html",
  "title": "new app",
  "icon": "icon.png",
  "largeIcon": "largeIcon.png"
}

Deploy the web app on a TV device

This section describes how to package the web app and install it on a webOS TV device. You will be using ares-package, ares-install, and ares-setup-device to deploy web apps.

If you are using webOS TV Simulator, skip this step and move to Launch the web app.

Package the web app

The first step is to create a package file (.ipk) of your app using the ares-package command.

Before executing the packaging command, you need to check if the essential files exist. The ares-package command finds and reads the appinfo.json file, where required fields, such as main and icon, are defined, from the app directory. For the same reason, the icon image file and main page file also must exist in the correct path.

Package the web app only

Execute the following command to package the app in the ./sampleApp directory.

ares-package ./sampleApp

Package the web app with JavaScript service

Execute the following command to package the app in the sampleApp directory together with the service in the sampleService directory.

ares-package ./sampleApp ./sampleService

Now you can see that the package file exists in the directory from which you execute the command.

Install the web app

Install the created package file on your device using theares-install command. You can also see the list of target devices using the ares-install command. Use theares-setup-device command to modify the settings of a device.

List target devices

Use the ares-setup-device command to check the name, platform type, description, and SSH access address of target devices.

Execute the following command to see the list of target devices.

ares-setup-device --list

The following is the sample result of the command. The emulator is included in the default device list.

name        deviceinfo                 connection    profile
---------   ------------------------   ------------  --------
emulator    developer@127.0.0.1:6622   ssh           tv
tv          prisoner@10.123.45.67      ssh           tv

With the ares-setup-device command, you can check the list with more details with -F, --listfulloptions. The following shows the command and the sample result.

ares-setup-device --listfull
[
  {
    "profile": "tv",
    "name": "tv",
    "deviceinfo": {
        "ip": "10.123.45.67",
        "port": "9922",
        "user": "prisoner"
    },
    "connection": [
        "ssh"
    ],
    "details": {
        "platform": "starfish",
        "privatekey": "tv_webos",
        "passphrase": "ares-setup-device --full",
        "description": "new device"
    }
  },
  {
    "profile": "tv",
    "name": "emulator",
    "deviceinfo": {
        "ip": "127.0.0.1",
        "port": "6622",
        "user": "developer"
    },
    "connection": [
    "ssh"
    ],
    "details": {
        "platform": "starfish",
        "privatekey": "webos_emul",
        "description": "LG webOS TV Emulator"
    }
  }
]

Modify the settings of a target device

The default loopback address needs to be changed to the remote host address if you are using the emulator on the remote computer for testing. The following example describes how to set the host address of the emulator to the target device.

ares-setup-device --modify emulator --info "host=10.177.231.137"

Re-check the device list to confirm if the host address of the target device has been modified as shown in the following example.

ares-setup-device --list

name     deviceinfo                     connection  profile
-------- -----------------------------  ----------  -------
tv       prisoner@10.123.45.67          ssh         tv
emulator developer@10.177.231.137:6622  ssh         tv

There is another way to change the target device’s information with the interactive mode of the ares-setup-device command. The following example shows how to change the target device’s host address in the interactive mode. Run the ares-setup-device command with no option, and it will show the list of target devices and start the interactive mode as below.

ares-setup-device

name     deviceinfo                connection  profile
-------- ------------------------  ----------  --------
tv       prisoner@10.123.45.67     ssh         tv
emulator developer@127.0.0.1:6622  ssh         tv

** You can modify the device info in the above list, or add new device.
? Select
> add
  modify
  remove

If you do not want to change the previous value, press the enter key without any value. For more information about the command usage, see ares-setup-device.

Install the package file of your web app

Make sure that your target device is running. Execute the following command with the name of the target device and package file as parameters to to install the package file on the target device.

ares-install --device myTV ./com.domain.app_0.0.1_all.ipk

If the installation is successful, you will see a success message.

To verify the installation, execute the following command to see the list of installed app IDs and check that your app ID exists in the result.

ares-install --device myTV --list

Remove a web app

Use the ares-install command with the--remove option to remove an app from the device. You need to enter the app ID to remove as a parameter. Execute the following command to remove your app from the target device.

ares-install --device myTV --remove com.domain.app

Run the web app

Use the ares-launch command to launch or close your web app.

Launch the web app

Execute the ares-launch command with the device name and app ID as parameters to launch the app on the target device.

ares-launch --device myTV com.domain.app

After executing the command, check if your app started on the target device.

Close the web app

Execute the ares-launch command with the--close option, in addition to the name of the target device and the app ID used to launch the app, to close the app on the target device.

ares-launch --device myTV --close com.domain.app

Debug the web app

You can monitor the execution information of web apps or JS services running on the target device with Web Inspector and Node Inspector, and to do so, you need to create a package file (.ipk) without minifying. This section describes how to create a package file and execute Web Inspector and Node Inspector for debugging purposes.

Package the web app without minifying

When creating a package file (.ipk), the ares-packagecommand reduces and merges the source code and adjusts and shrinks variable names and line spacing, which is called minifying. Minifying makes debugging difficult.

Therefore, for debugging purposes, use the --no-minifyoption of the ares-package command to omit the minifying task.

ares-package --no-minify ./sampleApp

Launch Inspectors

The webOS TV provides Web Inspector and Node Inspector for debugging of web apps and JS services, respectively.

Launch Web Inspector

For debugging of web apps, the ares-inspect command provides Web Inspector that displays the execution information of apps.

Execute the following command while the app is running:

ares-inspect --device myTV --app com.domain.app --open

With the --open option, Web Inspector opens on the default browser of your PC. Note that Web Inspector and Node Inspector work properly on Chromium-based browsers.

To use the Inspectors, the proper version of Chromium, compatible with the webOS TV version, should be installed on your PC. The following table lists the compatible Chromium version by webOS TV version and their download links.

You will see Web Inspector as in the below image.

Launch Node Inspector

For debugging of JS services, the ares-inspect command also provides Node Inspector that displays the execution information of JS services.

Execute the following command while the JS service is working:

ares-inspect --device myTV --service com.domain.app.myservice --open

You will see Node Inspector as in the below image:

Test the web app

This section describes how to test your web app on the TV device or the Simulator with CLI. About debugging of a web app on webOS Studio, see Debug the app on webOS Studio.

Test without installation

You can test code changes to your web app without packaging, installing, and running the app on a TV device.

The --hosted(-H) option of theares-launch command allows you to test the code changes easily on the TV device. If the --hosted option is used with the app directory, an app with idcom.sdk.ares.hostedapp is launched on the device and it opens the files in the directory. From CLI v1.12.0, the auto-reloading function is added, so as soon as you make and save modification to your app files, the app on the TV device is automatically reloaded.

Example

The following is an example of testing a sample app after creating it using CLI without steps for packaging and installation.

# Generate the sample app for test
$ ares-generate ./sampleApp
? app id com.domain.app
? title new app
? version 0.0.1
Generating basic in ./sampleApp
Success

# Test the sample app on the target device (name: myTV) without packaging and installation
$ ares-launch -H ./sampleApp -d myTV
Installing package
./sampleApp/com.domain.app.ipk
Ares Hosted App is now running...

• To terminate, enter Ctrl + C.

How to ignore specific files from auto-reloading

To exclude certain files with specific extensions or under specific directories from auto-reloading, create a .reloadignore file. This .reloadignore file should be located in the root directory of the app to test, and the file itself will be excluded from packaging of the app.

Add the absolute or relative path of the files or directories to exclude from auto-reloading into the .reloadignore file. Each item will be distinguished by a line feed, and the relative path of items (except for cases starting with **) will be converted into an absolute path based on the root directory of the app before being applied.

Even if you modify the .reloadignore file while auto-reloading is on, the modification will apply immediately without needing to terminate and re-run the command.

The following is an example of a .reloadignore file.

appinfo.json
tests
**/tmp
**/*.png

• appinfo.json - The appinfo.json file in the root directory will be ignored.
• tests - Directories and files under the tests directory in the root directory will be ignored.
• **/tmp - Any tmp directories and files in the app’s working directory will be ignored.
• **/*.png - Any files with the .png extension in the app’s working directory will be ignored.

With this option, however, you cannot test apps that include JS services.

Test on the Simulator

The ares-launch command with the--simulator and --simulator-path option runs webOS TV Simulator to test an app.

With the command, the execution file of webOS TV Simulator of the specified version, by the --simulator option, in the specified path, by the --simulator-path option, is run, and your app will be launched on that Simulator.

For how to install and use Simulator, see Simulator Installation and Simulator Developer Guide.

The following is an example of running the app in the sampleApp directory on the webOS TV 23 Simulator in the specified path.

ares-launch -s 23 -sp /home/webOS_TV_23_Simulator_1.3.0 sampleApp

Test on a local server

The ares-server command runs a web server for testing a local file. The web server will run on the given path.

Execute the command to start a web server on your app source directory.

ares-server ./sampleApp

You can open your app with the given URL.

Local server running on http://localhost:7496

If you want to open with the default browser of your PC directly, use--open option as below:

ares-server ./sampleApp --open

Monitor the resource usage

The function for monitoring the usage of CPU and memory, which has been provided in Beanviser, is added in CLI from v1.12.0.

Using the ares-device command with the--resource-monitor (-r) option, you can monitor the usage of CPU and memory at system or process level. You can also set the time interval to get the usage data periodically and save the data in a .csv file.

For details about each option and parameter, see ares-device.

Monitor at system level

This example displays the system-level CPU and memory usage.
