Install the basic tools
Install the basic tools, Command Line Interface (CLI), Visual Studio (VS) Code Extension, and Simulator, as a start. You will most likely need them in developing an app for webOS TV.
- The CLI provides a collection of commands for creating and managing an app, allowing you to develop and test without a specific IDE.
- If you are familiar with VS Code, you can work on it with VS Code Extension for webOS TV.
- The Simulator is a more visualized tool that provides an environment for app development, including debugging. It can be run on most PCs without additional environment settings.
Try building a first app
Before jumping into writing your own app, we suggest you get used to webOS TV app with the simplest form of it. Try building your first app.
Learn the basics about webOS TV apps
There are some basics about webOS TV apps that will help you understand how the apps work and come up with the idea about your own one.
Design your app
Now you design your app!
Implement the app
This phase is where you can make the most of webOS TV to implement functions and features of your app.
Test and debug the app
Test your app if it works as you expected and remove all the bugs that deteriorate its usability and performance.
- Examine how your app works on the Simulator. Or to test the app on a real TV, use Developer Mode App.
- On the CLI, you can monitor the usage of CPU and memory using ares-device-info. See Monitoring Resource Usage.
- Use Web Inspector to monitor your app with the execution information or Node Inspector to debug JS services used.
- Beanviser measures the performance of your app, helping you optimize it before the app goes live.
Examine the app with the checklist
Before submitting your app, you need to examine the app using the provided self-checklist to accelerate the submission process.
- The self-checklist presents the criteria that LG app quality assurance team uses, so you can pre-inspect the quality of your app.
