The release of the open webOS Open Source Edition 2.10 has been announced, which can be used on various portable devices, boards, and automotive infotainment systems. The Raspberry Pi 4 boards are considered as the reference hardware platform. The platform is developed in a public repository under the Apache 2.0 license, with development overseen by the community, following a collaborative governance model. <\/p>\n

The webOS platform was originally developed by Palm in 2008 and was used on Palm Pre and Pixie smartphones. After Palm was acquired in 2010, the platform came under Hewlett-Packard, which then attempted to use it in their printers, tablets, laptops, and PCs. In 2012, HP announced the transition of webOS to an independent open project, and in 2013 it began releasing the source code for its components. In 2013, the platform was purchased by LG from Hewlett-Packard and is now used in over 70 million LG televisions and consumer devices. In 2018, the webOS Open Source Edition project was established, through which LG attempted to return to an open development model, attract other participants, and expand the range of devices supported by webOS. <\/p>\n

The webOS system environment is formed using the OpenEmbedded tools and base packages, as well as the build system and metadata set from the Yocto project. Key components of webOS include the System and Application Manager (SAM), which is responsible for running applications and services, and the Luna Surface Manager (LSM), which creates the user interface. The components are written using the Qt framework and the Chromium browser engine. <\/p>\n

Rendering is done through a composite manager using the Wayland protocol. For developing user applications, it is recommended to use web technologies (CSS, HTML5, and JavaScript) and the Enact framework based on React, although it is also possible to create programs in C and C++ with a Qt-based interface. The user interface and built-in graphical applications are mainly implemented as native programs written using QML technology. By default, the Home Launcher interface is offered, optimized for touch screen navigation and featuring a concept of interchangeable cards instead of windows.

Data is stored in a structured format using JSON with the DB8 storage system, which uses LevelDB as the backend. Initialization is done through bootd based on systemd. For multimedia content processing, the uMediaServer and Media Display Controller (MDC) subsystems are available, and PulseAudio is used for sound. server<\/a> For automatic firmware updates, OSTree and atomic partition replacement are used (two system partitions are created, one of which is active while the other is used for updating). <\/p>\n
