 When you extend the `WebComponent` class for your component, you only have to define the `template` and `properties`. Any change in any property value will automatically cause just the component UI to render.
 
-The result is a reactive UI on property changes. [View on CodePen ↗](https://codepen.io/ayoayco-the-styleful/pen/ZEwoNOz?editors=1010)

-## Usage
+## Inspirations and thanks
 
-In your component class:
+1. [htm](https://github.com/developit/htm) - I use it for the `html` function for tagged templates, and take a lot of inspiration in building the rendering implementation. It is highly likely that I will go for what Preact is doing... but we'll see.
+1. [fast](https://github.com/microsoft/fast) - When I found that Microsoft has their own base class I thought it was super cool!
+1. [lit](https://github.com/lit/lit) - `lit-html` continues to amaze me and I worked to make `wcb` generic so I (and others) can continue to use it
 
-```js
-// HelloWorld.mjs
-import WebComponent from "https://unpkg.com/web-component-base@latest/WebComponent.min.js";
-
-class HelloWorld extends WebComponent {
-  static properties = ["my-name", "emotion"];
-  get template() {
-    return `
-        <h1>Hello ${this.props.myName}${this.props.emotion === "sad" ? ". 😭" : "! 🙌"}</h1>`;
-  }
-}
-
-customElements.define('hello-world', HelloWorld);
-```
-
-
-In your HTML page:
-
-```html
-<head>
-  <script type="module" src="HelloWorld.mjs"></script>
-</head>
-<body>
-  <hello-world my-name="Ayo" emotion="sad">
-  <script>
-      const helloWorld = document.querySelector('hello-world');
-
-      setTimeout(() => {
-        helloWorld.setAttribute('emotion', 'excited');
-      }, 2500)
-  </script>
-</body>
-```
-
-The result is a reactive UI that updates on attribute changes:
-
-<img alt="UI showing feeling toward Web Components changing from SAD to EXCITED" src="https://git.sr.ht/~ayoayco/web-component-base/blob/main/assets/wc-base-demo.gif" width="400" />
-
-## `template` vs `render()`
-
-This mental model attempts to reduce the cognitive complexity of authoring components:
-
-1. The `template` is a read-only property (initialized with a `get` keyword) that represents *how* the component view is rendered.
-1. There is a `render()` method that triggers a view render.
-1. This `render()` method is *automatically* called under the hood every time an attribute value changed.
-1. You can *optionally* call this `render()` method at any point to trigger a render if you need.
-
-## Prop Access
-
- The `props` property of the `WebComponent` interface is provided for easy read/write access to a camelCase counterpart of *any* observed attribute.
-
-```js
-class HelloWorld extends WebComponent {
-  static properties = ["my-prop"];
-  onInit() {
-    let count = 0;
-    this.onclick = () => this.props.myProp = `${++count}`
-  }
-  get template() {
-    return `
-        <h1>Hello ${this.props.myProp}</h1>
-    `;
-  }
-}
-```
-
-Assigning a value to the `props.camelCase` counterpart of an observed attribute will trigger an "attribute change" hook.
-
-For example, assigning a value like so:
-```
-this.props.myName = 'hello'
-```
-
-...is like calling the following:
-```
-this.setAttribute('my-name','hello');
-```
-
-Therefore, this will tell the browser that the UI needs a render if the attribute is one of the component's observed attributes we explicitly provided with `static properties = ['my-name']`;
-
-> The `props` property of `WebComponent` works like `HTMLElement.dataset`, except `dataset` is only for attributes prefixed with `data-`. A camelCase counterpart using `props` will give read/write access to any attribute, with or without the `data-` prefix.
-> Another advantage over `HTMLElement.dataset` is that `WebComponent.props` can hold primitive types `number`, `boolean`, and `string`.
-
-### Alternatives
-
-The current alternatives are using what `HTMLElement` provides out-of-the-box, which are:
-1. `HTMLElement.dataset` for attributes prefixed with `data-*`. Read more about this [on MDN](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/dataset).
-1. Methods for reading/writing attribute values: `setAttribute(...)` and `getAttribute(...)`; note that managing the attribute names as strings can be difficult as the code grows.
-
-## Quick Start Example
-
-Here is an example of using a custom element in a single .html file. 
-
-```html
-<!DOCTYPE html>
-<html lang="en">
-  <head>
-    <title>WC Base Test</title>
-    <script type="module">
-      import WebComponent from "https://unpkg.com/web-component-base@latest/WebComponent.min.js";
-
-      class HelloWorld extends WebComponent {
-        static properties = ["my-name"];
-        get template() {
-          return `<h1>Hello ${this.props.myName}!</h1>`;
-        }
-      }
-
-      customElements.define("hello-world", HelloWorld);
-    </script>
-  </head>
-  <body>
-    <hello-world my-name="Ayo"></hello-world>
-    <script>
-        const helloWorld = document.querySelector('hello-world');
-        setTimeout(() => {
-            helloWorld.props.myName = 'Ayo zzzZzzz';
-        }, 2500);
-    </script>
-  </body>
-</html>
-```
-
-## Life-Cycle Hooks
-
-Define behavior when certain events in the component's life cycle is triggered by providing hook methods
-
-### onInit()
-- Triggered when the component is connected to the DOM
-- Best for setting up the component
-
-```js
-import WebComponent from "https://unpkg.com/web-component-base@latest/WebComponent.min.js";
-
-class ClickableText extends WebComponent {
-  // gets called when the component is used in an HTML document
-  onInit() {
-    this.onclick = () => console.log(">>> click!");
-  }
-
-  get template() {
-    return `<span style="cursor:pointer">Click me!</span>`;
-  }
-}
-```
-
-### afterViewInit()
-- Triggered after the view is first initialized
-
-
-```js
-class ClickableText extends WebComponent {
-  // gets called when the component's innerHTML is first filled
-  afterViewInit() {
-    const footer = this.querySelector('footer');
-    // do stuff to footer after view is initialized
-  }
-
-  get template() {
-    return `<footer>Awesome site &copy; 2023</footer>`;
-  }
-}
-```
-
-### onDestroy()
-- Triggered when the component is disconnected from the DOM
-- best for undoing any setup done in `onInit()`
-
-```js
-import WebComponent from "https://unpkg.com/web-component-base@latest/WebComponent.min.js";
-
-class ClickableText extends WebComponent {
- 
-  clickCallback() {
-    console.log(">>> click!");
-  }
-
-  onInit() {
-    this.onclick = this.clickCallback;
-  }
-
-  onDestroy() {
-    console.log(">>> removing event listener");
-    this.removeEventListener("click", this.clickCallback);
-  }
-
-  get template() {
-    return `<span style="cursor:pointer">Click me!</span>`;
-  }
-}
-```
-
-### onChanges()
-- Triggered when an attribute value changed
-
-```js
-import WebComponent from "https://unpkg.com/web-component-base@latest/WebComponent.min.js";
-
-class ClickableText extends WebComponent {
-  // gets called when an attribute value changes
-  onChanges(changes) {
-      const {property, previousValue, currentValue} = changes;
-      console.log('>>> ', {property, previousValue, currentValue})
-  }
-
-  get template() {
-    return `<span style="cursor:pointer">Click me!</span>`;
-  }
-}
-```
-
-## Library Size 
-
-The bundle size was reported to be 587 Bytes (minified & gzipped) by [bundlephobia](https://bundlephobia.com/package/web-component-base). Running [size-limit](https://npmjs.com/package/@size-limit/preset-small-lib) reports the base class size as around 760 Bytes (minified & brotlied), and using the `WebComponent.min.js` version gets it down to around 400 Bytes.

+    <script type="module">
+      import { WebComponent } from 'https://unpkg.com/web-component-base@latest/index.js'
+
+      class HelloWorld extends WebComponent {
+        static props = {
+          myName: 'World',
+        }
+        get template() {
+          return `<h1>Hello ${this.props.myName}!</h1>`
+        }
+      }
+
+      customElements.define('hello-world', HelloWorld)

+**Web Component Base (WCB)** 
+<Badge text="alpha" variant="danger" /> is a zero-dependency, tiny JS base class for creating reactive [custom elements](https://developer.mozilla.org/en-US/docs/Web/API/Web_Components/Using_custom_elements) easily.
+
+When you extend the WebComponent class for your custom element, you only have to define the template and properties. Any change in an observed property's value will automatically cause the component UI to render.
+
+The result is a reactive UI on property changes.
+
+Note that there's a trade off between productivity & lightweight-ness here, and the project aims to help in writing custom elements in the same way more mature and better maintained projects already do. Please look into popular options such as [Microsoft's FASTElement](https://fast.design/) & [Google's LitElement](https://lit.dev/) as well.
+
+## Project Status
+
+Treat it as a **stable alpha** product. Though the public APIs are stable, most examples are only useful for simple atomic use-cases due to remaining work needed on the internals.
+
+<Aside type="caution" title="Important">
+For building advanced interactions, there is an in-progress work on smart diffing to prevent component children being wiped on interaction.
+</Aside>
+
+<Aside type="tip">
+If you have some complex needs, we recommend using the `WebComponent` base class with a more mature rendering approach like `lit-html`, and here's a demo for that: [View on CodePen](https://codepen.io/ayoayco-the-styleful/pen/ZEwNJBR?editors=1010).
+</Aside>
+
+## Installation
+
+The library is distributed as complete ECMAScript Modules (ESM) and published on [NPM](https://ayco.io/n/web-component-base). Please open a [GitHub issue](https://github.com/ayoayco/wcb/issues/new) or [discussion](https://github.com/ayoayco/wcb/discussions) for problems or requests regarding our distribution. You can also submit a ticket in [SourceHut](https://todo.sr.ht/~ayoayco/wcb).
+
+### Import via CDN
+
+It is possible to import directly using a CDN like [esm.sh](https://esm.sh/web-component-base) or [unpkg](https://unpkg.com/web-component-base) in your vanilla JS component or HTML files. In all examples in this document, we use `unpkg` but you can find on CodePen examples that `esm.sh` also works well.
+
+Additionally, we use `@latest` in the rest of our [usage](/usage) and [examples](/examples) here for simplicity, but take note that this incurs additional resolution steps for CDNs to find the actual latest published version. You may replace the `@latest` in the URL with specific versions as shown in our CodePen examples, and this will typically be better for performance.
+
+```js
+import { WebComponent } from 'https://unpkg.com/web-component-base@latest/index.js'
+```
+
+### Installation via npm
+
+Usable for projects with bundlers or using import maps pointing to the specific files downloaded in `node_modules/web-component-base`.
+
+```bash
+npm i web-component-base

+
+The `props` property of the `WebComponent` interface is provided for easy read/write access to a camelCase counterpart of _any_ observed attribute.
+
+```js
+class HelloWorld extends WebComponent {
+  static props = {
+    myProp: 'World',
+  }
+  get template() {
+    return html` <h1>Hello ${this.props.myProp}</h1> `
+  }
+}
+```
+
+Assigning a value to the `props.camelCase` counterpart of an observed attribute will trigger an "attribute change" hook.
+
+For example, assigning a value like so:
+
+```
+this.props.myName = 'hello'
+```
+
+...is like calling the following:
+
+```
+this.setAttribute('my-name','hello');
+```
+
+Therefore, this will tell the browser that the UI needs a render if the attribute is one of the component's observed attributes we explicitly provided with `static props`;
+
+<Aside type="note">
+The `props` property of `WebComponent` works like `HTMLElement.dataset`, except `dataset` is only for attributes prefixed with `data-`. A camelCase counterpart using `props` will give read/write access to any attribute, with or without the `data-` prefix.
+
+Another advantage over `HTMLElement.dataset` is that `WebComponent.props` can hold primitive types 'number', 'boolean', 'object' and 'string'.
+</Aside>
+
+### Alternatives
+
+The current alternatives are using what `HTMLElement` provides out-of-the-box, which are:
+
+1. `HTMLElement.dataset` for attributes prefixed with `data-*`. Read more about this [on MDN](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/dataset).
+1. Methods for reading/writing attribute values: `setAttribute(...)` and `getAttribute(...)`; note that managing the attribute names as strings can be difficult as the code grows.

+
+It is highly recommended to use the second approach, as with it, browsers can assist more for performance.
+
+## Using style objects
+
+When using the built-in `html` function for tagged templates, a style object of type `Partial<CSSStyleDeclaration>` can be passed to any element's `style` attribute. This allows for calculated and conditional styles. Read more on style objects [on MDN](https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleDeclaration).

+This mental model attempts to reduce the cognitive complexity of authoring components:
+
+1. The `template` is a read-only property (initialized with a `get` keyword) that represents _how_ the component view is rendered.
+1. There is a `render()` method that triggers a view render.
+1. This `render()` method is _automatically_ called under the hood every time an attribute value changed.
+1. You can _optionally_ call this `render()` method at any point to trigger a render if you need (eg, if you have private unobserved properties that need to manually trigger a render)
+1. Overriding the `render()` function for handling a custom `template` is also possible. Here's an example of using `lit-html`: [View on CodePen ↗](https://codepen.io/ayoayco-the-styleful/pen/ZEwNJBR?editors=1010)

+Often times, when simple websites need a quick custom element, the simplest way is to create one extending from `HTMLElement`. However, it can quickly reach a point where writing the code from scratch can seem confusing and hard to maintain especially when compared to other projects with more advanced setups.
+
+Also, when coming from frameworks with an easy declarative coding experience (using templates), the default imperative way (e.g., creating instances of elements, manually attaching event handlers, and other DOM manipulations) is a frequent pain point we see.
+
+By taking out bigger concerns that [a metaframework](https://github.com/ayoayco/mcfly) should handle, this project aims to focus on keeping the component-level matters simple and lightweight. This allows for addressing the said problems with virtually zero tooling required and thin abstractions from vanilla custom element APIs – giving you only the bare minimum code to be productive.

-# McFly Starter Project
-
-
-
-## Background
-This project was generated from the basic template for **McFly** -- a no-framework framework that assists in leveraging the web platform.
-
-![template-basic](https://raw.githubusercontent.com/ayoayco/McFly/main/assets/template-basic.png)
-
-It contains example files to get you started using vanilla web technologies in a modern way. See the [Special Directories](#special-directories) section for more information.
-
-## Features
-The time has come for vanilla Web tech. 🎉
-
-✅ Create web apps with vanilla custom elements<br>
-✅ Write real .HTML files<br>
-✅ Have no frameworks or reactivity libraries on the browser<br>
-✅ Use server-side rendering<br>
-✅ Deploy anywhere<br>
-
-## Special directories
-**1. `./src/pages/`**
-- file-based routing for `.html` files
-- directly use custom elements & static fragments (no imports or registry maintenance needed)
-- use `<script server:setup>` to define logic that runs on the server, which then gets stripped away
-
-**2. `./src/components/`**
-- custom element constructor files (only `.js` files for now)
-- all components are automatically registered using their file names; a `hello-world.js` component can be used as `<hello-world>`
-- static `.html` fragments; a `my-header.html` fragment can be directly used as `<my-header>`
-
-**3. `./routes/api/`**
-- file-based routing for REST API endpoints
-- e.g., `./routes/api/users.ts` can be accessed via `http://<domain>/api/users`
-- TypeScript or JavaScript welcome!
-
-## McFly config
-
-To tell McFly you want to use components, pass the mode (only `"js"` for now) to the `components` prop mcfly.config.ts
-
-```js
-import defineConfig from "./packages/define-config";
-
-export default defineConfig({
-  components: "js",
-});
-
-```
-## Commands
-
-The following commands are available to you on this project. Add more, or modify them as needed in your `./package.json` file.
-
-| Command | Action |
-| --- | --- |
-| npm start | Start the development server |
-| npm run prepare | Prepare the workspace |
-| npm run build | Locally generate the app's build files to `./output` |
-| npm run preview | Preview the built app locally |
-
-
----
-*Just keep building*<br />

-          By extending our base class, you get an easy authoring experience as you would expect in writing your components:</p>
-        <ul>
-          <li>A <code-block inline>props</code-block> API that synchronizes your components' property values and HTML attributes</li>
-          <li>Sensible life-cycle hooks that you understand and remember</li>
-          <li>Extensible templates & renderer (examples in-progress)</li>
-          <li>Provided out-of-the-box with <a href="https://ayco.io/gh/McFly">McFly</a>, a powerful no-framework framework</li>

-          When you extend the WebComponent class for your component, you only have to define the template and properties. Any change in any property value will automatically cause just the component UI to render.
-        </p>
-
-        <p>The result is a reactive UI on property changes: <my-counter></my-counter></p>
