1# Introduction to ArkWeb 2 3## When to Use 4 5ArkWeb provides **Web** components to display web page content in applications. You can use the components in the following scenarios: 6- Web page integration: Applications can use **Web** components to embed web page content to reduce development costs and improve development and operation efficiency. 7 8- Web browsing: Browser applications can use **Web** components to open third-party web pages, browse web pages in traceless mode, and set advertisement blocking. 9 10- Applet: Host applications of applets can use **Web** components to render the pages of the applets, implement same-layer rendering, and take over video playback. 11 12## Available Capabilities 13 14The **Web** component provides various capabilities for you to control web pages, including: 15 16- Web page loading: declarative loading and off-screen loading of web pages. 17 18- Lifecycle management: component lifecycle status change and web page loading status change notification. 19 20- Common attributes and events: management of user agent, cookie and storage, font and dark mode, and permission. 21 22- Interaction with the application UI: The custom text selection menu, context menu, and file upload page can interact with the application UI. 23 24- Interaction between applications and web pages through JavaScriptProxy. 25 26- Security and privacy: traceless browsing mode, advertisement blocking, and Secure Shield mode. 27 28- Maintenance and debugging capability: [DevTools](web-debugging-with-devtools.md) for debugging, crashpad for collecting crash information of the **Web** component. 29 30- Other advanced capabilities: same-layer rendering with system components, network and media playback takeovers, and custom input method for **Web** component text boxes<!--RP1--><!--RP1End-->. 31 32## Constraints 33 34- You can obtain the support for W3C standards based on the ArkWeb kernel version at related websites. For example, **https://developer.mozilla.org/en-US/** and **https://webassembly.org/features/**. 35 36- **Web** kernel version: ArkWeb is developed based on Chromium. The corresponding Chromium versions are as follows. 37 38 | OS Version| Chromium Version| 39 | ---|---| 40 | OpenHarmony 4.0 and earlier| M99 | 41 | OpenHarmony 4.1-5.1 | M114 | 42 | OpenHarmony 6.0 | M132 | 43 44## Samples 45 46The following samples are provided to help you better understand how to develop **Web** components: 47 48- [Using Web Components (ArkTS) (API9)](https://gitee.com/openharmony/codelabs/tree/master/ETSUI/WebCookie) 49 50- [Using Web Components in Developing Lottery Applets (ArkTS) (API9)](https://gitee.com/openharmony/codelabs/tree/master/ETSUI/WebComponent) 51
