JS Service Development Workflow

This page outlines the steps to develop JS services for webOS IoT.

Developing a JS service requires the following steps:

1. Implement

   • Writing the JS service code (<JS_service_name>.js)
   • Preparing README.md that describes the project

2. Configure

   • Configuring the service metadata file (package.json)
   • Preparing the LS2 configuration files, including a Service Configuration file, a Role file, and Permission files
   • Configuring the CMake build script (CMakeLists.txt)

3. Build

   • Writing a recipe to build the service on the Yocto build environment
   • Configuring the local source directory
   • Building the service

4. Run and verify

   • Installing and running the service on the target
   • Verifying the service functionality

5. Deploy

   • Adding the service to the webOS IoT build recipe
   • Building the webOS IoT image
   • Flashing the image to the target
