# Web Component Base
> [!Note]
> **Quality of Life improvements shipped (v5.1)** — We now have typed props and a [CEM Analyzer Plugin](https://webcomponent.io/cem-plugin/) that makes developer exerience so much better with code editors and other tooling. Composing stylesheets and a fix for boolean properties behavior is included as well. See the [change log](https://github.com/ayo-run/wcb/releases/tag/v5.1.0) for more details. Next up: more improvements to Boolean props and **faster templates!**

[![Bundle Size](https://img.shields.io/bundlephobia/minzip/web-component-base)](#library-size)
🤷‍♂️ 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 ✨
This is the base class used for web components in Ayo's projects, primarily [cozy-games](https://git.ayo.run/ayo/cozy-games), [mcfly](https://git.ayo.run/ayo/mcfly/), his [personal site](https://ayo.ayco.io), his [blog](https://ayos.blog), and [others](https://git.ayo.run/ayo).
Next actions:
1. [Read the docs](https://webcomponent.io)
2. [View a demo on CodePen](https://codepen.io/ayoayco-the-styleful/pen/ZEwoNOz?editors=1010).
![counter example code snippet](https://git.sr.ht/~ayoayco/wcb/blob/main/assets/IMG_0682.png)
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.
## Want to get in touch?
There are many ways to get in touch:
1. Open a [GitHub issue](https://github.com/ayo-run/wcb/issues/new) or [discussion](https://github.com/ayo-run/wcb/discussions)
1. Submit a ticket via [SourceHut todo](https://todo.sr.ht/~ayoayco/wcb)
1. Email me: [hi@ayo.run](mailto:hi@ayo.run)
## Inspirations and thanks
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
## Size change log
See [`size-change-log.md`](./size-change-log.md) for a running record of how each correctness/feature change affects the `WebComponent` base class bundle size, with the reason and benefit of each.
