# Installation & Setup
|
|
|
|
SigPro is designed to be drop-in ready. Whether you are building a complex application with a bundler or a simple reactive widget in a single HTML file, SigPro scales with your needs.
|
|
|
|
## 1. Installation
|
|
|
|
Choose the method that best fits your workflow:
|
|
|
|
<div class="tabs tabs-box w-full mt-8 mb-12">
|
|
<input type="radio" name="install_method" class="tab border-base-300" aria-label="npm" checked />
|
|
<div class="tab-content bg-base-100 border-base-300 rounded-box p-6">
|
|
|
|
```bash
|

## 2. Quick Start Examples
|
|
|
|
SigPro uses **PascalCase** for Tag Helpers (e.g., `Div`, `Button`) to provide a clean, component-like syntax without needing JSX.
|
|
|
|
<div class="tabs tabs-box w-full mt-8 mb-12 bg-base-200/50 p-2 rounded-xl border border-base-300">
|
|
<input type="radio" name="quick_start_tabs" class="tab !rounded-lg" aria-label="Mainstream (Bundlers)" checked />
|
|
<div class="tab-content bg-base-100 border-base-300 rounded-lg p-6 mt-2">
|
|
|
|
```javascript
|
|
// File: App.js
|
|
import { $ } from "sigpro";
|
|
|
|
export const App = () => {
|
|
const $count = $(0);
|
|
|
|
// Tag Helpers like Div, H1, Button are available globally
|
|
return Div({ class: "card p-4" }, [
|
|
H1(["Count is: ", $count]),
|
|
Button(
|
|
{
|
|
class: "btn btn-primary",
|
|
onclick: () => $count((c) => c + 1),
|
|
},
|
|
"Increment",
|
|
),
|
|
]);
|
|
};
|
|
|
|
// File: main.js
|
|
import { $ } from "sigpro";
|
|
import { App } from "./App.js";
|
|
|
|
$mount(App, "#app");
|
|
```
|
|
|
|
</div>
|
|
|
|
<input type="radio" name="quick_start_tabs" class="tab !rounded-lg" aria-label="Classic (Direct CDN)" />
|
|
<div class="tab-content bg-base-100 border-base-300 rounded-lg p-6 mt-2">
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html lang="en">
|
|
<body>
|
|
<div id="app"></div>
|
|
|
|
<script type="module">
|
|
import { $ } from "https://cdn.jsdelivr.net/npm/sigpro@latest/+esm";
|
|
|
|
const $name = $("Developer");
|
|
|
|
// No need to import Div, Section, H2, Input... they are global!
|
|
const App = () =>
|
|
Section({ class: "container" }, [
|
|
H2(["Welcome, ", $name]),
|
|
Input({
|
|
type: "text",
|
|
class: "input input-bordered",
|
|
$value: $name, // Automatic two-way binding
|
|
placeholder: "Type your name...",
|
|
}),
|
|
]);
|
|
|
|
$mount(App, "#app");
|
|
</script>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
</div>
|
|
</div>

## 3. Global by Design
|
|
|
|
One of SigPro's core strengths is its **Global API**, which eliminates "Import Hell".
|
|
|
|
- **The `$` Function:** Once loaded, it attaches itself to `window.$`. It handles state, effects, and DOM mounting.
|
|
- **Tag Helpers (PascalCase):** Common HTML tags (`Div`, `Span`, `Button`, `Input`, etc.) are automatically registered in the global scope.
|
|
- **Custom Components:** We recommend using **PascalCase** (e.g., `UserCard`) or prefixes like `_Input` to keep your code organized and distinguish your logic from standard tags.
|
|
|
|
## 4. Why no build step?
|
|
|
|
Because SigPro uses **native ES Modules** and standard JavaScript functions to generate the DOM, you don't actually _need_ a compiler like Babel or a transformer for JSX.
|
|
|
|
- **Development:** Just save and refresh. Pure JS, no "transpilation" required.
|
|
- **Performance:** Extremely lightweight. Use any modern bundler (Vite, esbuild) only when you are ready to minify and tree-shake for production.
|
|
|
|
## 5. Why SigPro? (The Competitive Edge)
|
|
|
|
SigPro stands out by removing the "Build Step" tax and the "Virtual DOM" overhead. It is the closest you can get to writing raw HTML/JS while maintaining modern reactivity.
|
|
|
|
| Feature | **SigPro** | **SolidJS** | **Svelte** | **React** | **Vue** |
|
|
| :----------------- | :--------------- | :----------- | :----------- | :---------- | :---------- |
|
|
| **Bundle Size** | **~2KB** | ~7KB | ~4KB | ~40KB+ | ~30KB |
|
|
| **DOM Strategy** | **Direct DOM** | Direct DOM | Compiled DOM | Virtual DOM | Virtual DOM |
|
|
| **Reactivity** | **Fine-grained** | Fine-grained | Compiled | Re-renders | Proxies |
|
|
| **Build Step** | **Optional** | Required | Required | Required | Optional |
|
|
| **Learning Curve** | **Minimal** | Medium | Low | High | Medium |
|
|
| **Initialization** | **Ultra-Fast** | Very Fast | Fast | Slow | Medium |
|
|
|

|
|
|
|
## 6. Key Advantages
|
|
|
|
- **Extreme Performance**: No Virtual DOM reconciliation. SigPro updates the specific node or attribute instantly when a Signal changes.
|
|
- **Fine-Grained Reactivity**: State changes only trigger updates where the data is actually used, not on the entire component.
|
|
- **Native Web Standards**: Everything is a standard JS function. No custom template syntax to learn.
|
|
- **Zero Magic**: No hidden compilers. What you write is what runs in the browser.
|
|
- **Global by Design**: Tag Helpers and the `$` function are available globally to eliminate "Import Hell" and keep your code clean.
|
|
|
|
## 7. Summary
|
|
|
|
SigPro isn't just another framework; it's a bridge to the native web. By using standard ES Modules and functional DOM generation, you gain the benefits of a modern library with the weight of a utility script.
|
|
|
|
**Because, in the end... why fight the web when we can embrace it?**
