+# About hotosm/ui
+
+HOT maintains many web based tools that require a UI.
+
+Typically these interfaces were developed using React, due to existing
+experience and to avoid fragmentation.
+
+Going forward HOT requires a more flexible approach that can be used in
+multiple different frameworks (including directly in HTML & also HTMX).
+
+The solution to this is Web Components, which are framework agnostic.
+
+## Web Components
+
+- We can probably all agree that as of 2024, the state of the JS framework
+  ecosystem is quite messy: it's just too fragmented to make an informed
+  "future proof" decision.
+- Web Components are a web standard, so should be supported for the long term,
+  but adoption has been slow for
+  [various reasons](https://daverupert.com/2023/07/why-not-webcomponents/)
+  (web standards are complex and very slow to update)
+- Web Components sound like the most sustainable solution, but they historicaly
+  also had some problems (shadow DOM styling, styling framework integration,
+  performance, component versioning).
+- A few of these issues are addressed by frameworks such as Lit.
+  Although we should be aware, this is yet another framework.
+
+### What are they?
+
+Web Components are built upon four existing technologies:
+
+- Custom Elements:
+  - Allows developers to define their own HTML elements with custom
+    behavior and properties.
+- Shadow DOM:
+  - Provides encapsulation by creating a scoped DOM subtree for a component,
+    isolating its styles and structure from the rest of the document.
+- HTML Templates:
+  - Enables the creation of template elements that can be cloned
+    and inserted into the DOM.
+  - Represented by the `<template>` and `<slot>` elements
+- ~~HTML Imports~~:
+  - This fourth technology related to Web Components was since abandoned.
+  - This is no longer required, e.g. **ES6 module imports** can be used instead.
+
+### Advantages
+
+- Reusability:
+  - Components can be easily reused across different projects,
+    promoting code modularity and reducing redundancy.
+- Encapsulation:
+  - Shadow DOM enables encapsulation, preventing style and structure
+    conflicts between components and the rest of the page.
+- Interoperability:
+  - Web Components can be used with any modern web framework or library,
+    enhancing interoperability and flexibility.
+- Maintainability:
+  - Components provide a cleaner and more maintainable code structure by
+    breaking down the application into manageable, isolated units.
+- Consistency:
+  - Web Components promote consistency in design and functionality
+    by encouraging the use of standardized, reusable elements.
+
+### Challenges
+
+- Integration with Frameworks
+  - Almost all frameworks support using Web Components,
+    [except React](https://custom-elements-everywhere.com/) where it has been
+    a work in progress since 2017.
+  - This is not an issue, as Lit provides
+    [React wrappers](https://lit.dev/docs/frameworks/react/) to solve this.
+- Standardization Challenges:
+  - Although Web Components are a W3C standard, the lack of universal adoption
+    and variations in implementation can create challenges for consistent
+    behavior across different environments.
+- ~~Browser Support~~ this is
+  [no longer a major issue](https://caniuse.com/?search=web%20components)
+- ~~Performance Concerns~~
+  - The use of Shadow DOM and other features may introduce performance overhead.
+  - This is partly solved by Lit's use of `DOM Diffing` and other performance
+    enhancements.
+
+**Most of the limitations are addressed by using a framework like Lit**.
+
+### Web Component Example
+
+A vanilla Web Component:
+
+```js
+class MyElement extends HTMLElement {
+  constructor() {
+    super();
+    const shadow = this.attachShadow({ mode: "open" });
+    const div = document.createElement("div");
+    div.textContent = "Hello, World!";
+    shadow.appendChild(div);
+  }
+}
+
+customElements.define("my-element", MyElement);
+```
+
+The component can be used directly in HTML:
+
+```html
+<div>
+  <!-- other html -->
+  <my-element></my-element>
+</div>
+```
+
+## Class Variance Authority
+
+- In UI design we need to consider **variants** of components.
+- This may be changes to size, colour, functionality, icons, etc.
+- Class Variance Authority (CVA) makes this easy by allowing us to define
+  all of the possible variants and the associated CSS.
+- We can even have component variants made from multiple variants.
+- The result is a component that includes type-safe props that can be used
+  to style our components is various different ways.
+
+### CVA Example
+
+With React:
+
+```js
+// components/button.tsx
+
+import { cva } from "class-variance-authority";
+
+const buttonStyles = cva("font-semibold rounded border", {
+  variants: {
+    intent: {
+      primary: "bg-blue-500 text-white border-transparent hover:bg-blue-600",
+      secondary: "bg-white text-gray-800 border-gray-400 hover:bg-gray-100"
+    },
+    size: {
+      small: "text-sm py-1 px-2",
+      medium: "text-base py-2 px-4",
+    },
+  },
+  defaultVariants: {
+    intent: "primary",
+    size: "medium",
+  },
+});
+
+// regular button props
+type ButtonProps = {
+  label: string;
+  onClick?: (onClickProps: any) => void;
+  icon?: IconType; // defined elsewhere, pretend this is JSX
+}
+
+// merging button props and CVA variant props with TS utility types
+type buttonVariantsProps = VariantProps<typeof buttonStyles>;
+interface Props
+  extends ButtonProps,
+    // making intent variant required
+    Omit<buttonVariantsProps, "intent">,
+    Required<Pick<buttonVariantsProps, "intent">> {}
+
+// actual button componenent
+const Button = ({label, onClick, icon, intent, size}: Props) => {
+  return (
+    <button
+      className={buttonStyles({intent, size})}
+      onClick={onClick}
+    >
+      {icon && <Icon/>}
+      {label}
+    </button>
+  )
+}
+```
