HTML packages allow an entire HTML structure to be distributed to players, extracted and then a nominated URL opened (usually `index.html`). The major advantage of this over using a web page is that your HTML will be local to the player and available even if the Player loses network connectivity. Unlike Embedded Widgets, the Player does not inject any of its core libraries, although it will attempt to call `xiboIC` in case interactive control has been included (see Player Control). ## Referencing Resources Your entry point (`index.html`) will likely need to reference other files, be they scripts, style sheets or images. These resources must be referenced relatively, because your entire package will be inside a folder. You are guaranteed that the folder structure is only one level deep, for example `http://localhost:9696/package_1234/index.html`. ## CORS HTML packages will be opened on the Player’s embedded web server, run on port 9696 by default. This means any XHR requests you make will be cross origin. If this is not acceptable for your use case then the only option remaining is a Web Page Widget and external hosting for your content. ## Player Browser Versions Where possible Xibo player implementations choose the chromium rendering engine, but effort should be made to thoroughly test your package HTML on the player it is intended for, or to make it cross browser. ## Player Control HTML Package Widgets can also make use of the API’s available for Player Control — see here: --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.xibosignage.com/developer/widgets/html-package.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
