Hyperview XML

Hyperview XML (HXML) is a hypermedia, XML-based format used to define mobile app screens. HXML provides a set of tags and attributes that define a screen's layout, styling, and available user interactions.

Behaviors

Behaviors in HXML define actions that should happen in the app, in response to a user-based trigger. Behaviors can either be specified as attributes on other HXML elements, or as a child <behavior> element.

  • Behavior attributes Goes in-depth about the HXML attributes used to define a behavior.
  • <behavior>: An element that accepts behavior attributes and applies the behavior to the parent element. Often used when an element needs to define multiple behaviors.

Display Elements

Display elements in HXML can be combined to define the layout of a screen.

  • <doc>: The top-level element in HXML, used to include multiple screens in one response.
  • <screen>: A single screen of a mobile app.
  • <header>: The header of a mobile app screen.
  • <body>: The body of a mobile app screen (everything below the header).
  • <view>: The basic building block of a screen's layout. Support flex styling, colors, borders, etc.
  • <text>: Any text content on a screen. Supports text styling.
  • <image>: Any image content on a screen.
  • <list>: Efficient layout of repeated items on a screen. Supports list-specific interactions like pull-to-refresh.
  • <section-list>: Efficient layout of sectioned (grouped) repeated items on a screen. Supports list-specific interactions like pull-to-refresh.
  • <section>: [Deprecated] Groups <item> and <section-title> elements in a <section-list>.
  • <section-title>: The header of a group of <item> in a <section-list>.
  • <item>: An individual item in a <list> or <section-list>.
  • <spinner>: Activity indicator element.

Input Elements

Input elements in HXML allow users to set local state on a Hyperview screen. This state can be serialized with backend requests, or used for client-side interactions.

  • <form>: An element used to group together several inputs for request serialization.
  • <text-field>: An element used to accept single-line text input.
  • <text-area>: An element used to accept multi-line text input.
  • <select-single>: An element that groups many <option> elements, and allows only one of the options to be selected at a time.
  • <select-multiple>: An element that groups many <option> elements, and allows any number of options to be selected/deselected.
  • <option>: An element that groups many <option> elements, and allows any number of options to be selected/deselected.

Style Elements

Style elements in HXML define rules for the appearance of display and input elements.o

  • <styles>: Groups together all of the <style> rules for a screen.
  • <style>: A single style rule with unique id in the screen, can set multiple appearance properties.
  • <modifier>: Defines an appearance that should override the default for a style under certain local conditions, such as a user tap, selection, etc.

React Native Client

The Hyperview RN Client is a library that can parse and render HXML in a React Native app.

  • The Hyperview class defines a component that takes an endpoint URL and configuration props to render Hyperview screens in an app.
  • Custom Elements: The Hyperview client can be extended by registering custom HXML elements and tags with custom RN components. This can be used to add elements with rich interactions, such as maps.
  • Custom Behaviors: The Hyperview client can be extended by registering custom callbacks that can be triggered via <behavior> elements in the HXML. Supports features like dispatching Redux actions, triggering phone calls and share sheets, event logging, etc.
