Native Service Development Workflow

This page outlines the steps to develop native services for webOS Open Source Edition (OSE).

Downloadable Native Services

Developing a downloadable native service requires the following steps:

1. Implement

   • Writing the native service code
   • Preparing a dummy app to package with the service

2. Configure

   • Configuring the service metadata file (services.json)
   • Configuring the CMake build script (CMakeLists.txt)

3. Build

   • Running the CMake build script and the Makefile

4. Package

   • Packaging the built binary file with the dummy app using the CLI

5. Install and Run

   • Installing the service on the target using the CLI
   • Launching the dummy app or entering commands using a terminal

Built-in Native Services

Developing a built-in native service requires the following steps:

1. Implement

   • Writing the native service code
   • Preparing README.md that describes the project

2. Configure

   • Preparing the LS2 configuration files, including a Service Configuration file, a Role file, and Permission files
   • Preparing the systemd configuration file
   • 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
   • Specifying the order of execution on the target

5. Deploy

   • Adding the service to the webOS OSE build recipe
   • Modifying the systemd execution list on webos-initscripts component
   • Building the webOS OSE image
   • Flashing the image to the target
