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
