| description | Client-side routing toolkit for Alpine.js applications using Pinecone Router v7.5, providing route matching, template rendering, handlers, and TypeScript support. Use when building SPAs with Alpine.js that require declarative HTML routing, external template loading, async data fetching, hash or history navigation, or programmatic route management. |
Pinecone Router v7.5
Overview
Pinecone Router is a small, easy-to-use, and feature-packed client-side router for Alpine.js. At approximately 3 KB gzipped with zero dependencies, it provides declarative HTML-based routing through Alpine.js directives (x-route, x-template, x-handler), supporting inline templates, external template fetching, async route handlers with abort support, navigation history management, hash routing, base path configuration, and full TypeScript definitions.
It integrates as an Alpine.js plugin and exposes three magic helpers — $router, $history, and $params — for accessing router state from within Alpine components.
When to Use
- Building single-page applications with Alpine.js that need client-side routing
- Routing without a build step (CDN or browser module installation)
- Applications needing inline HTML templates or externally fetched template files
- Routes that require async data fetching before rendering (handler-based guards and data loading)
- Projects needing navigation history with back/forward controls independent of the browser
- Hash-based routing for environments without server-side URL rewriting
- TypeScript projects requiring type-safe routing APIs
Core Concepts
Declarative Routing: Routes are declared in HTML using <template> elements with the x-route directive. No JavaScript route configuration is needed for basic setups.
Route Matching: Supports literal segments (/about), named params (/:id), optional params (/:id?), rest params (/:path+), wildcards (/:path*), file extensions (/:name.mp4), and extension patterns (/:name.(mp4|mov)). Trailing slashes are normalized, matching is case-insensitive.
Templates: Routes display content through x-template — either inline (children of the <template> tag) or external (fetched HTML files from URLs). Templates support preloading, target element rendering, and URL interpolation with route params.
Handlers: Functions that execute before templates render, registered via x-handler. Handlers receive a context object with route info and an AbortController for cancellation. They run sequentially, can be async, and can pass data between each other by returning values.
Navigation History: An independent history stack tracking visited paths (excluding duplicates and redirects), accessible via $history.back(), $history.forward(), $history.canGoBack(), and $history.entries.
Installation / Setup
CDN
Include before Alpine.js in the <head>:
<script src="https://cdn.jsdelivr.net/npm/pinecone-router@7.5.0/dist/router.min.js"></script>
<script defer src="https://cdn.jsdelivr.net/npm/alpinejs@3.14.9/dist/cdn.min.js"></script>
NPM
npm install pinecone-router
import PineconeRouter from 'pinecone-router'
import Alpine from 'alpinejs'
Alpine.plugin(PineconeRouter)
Alpine.start()
Browser Module (ESM)
import PineconeRouter from 'https://cdn.jsdelivr.net/npm/pinecone-router@7.5.0/dist/router.esm.js'
import Alpine from 'https://cdn.jsdelivr.net/npm/alpinejs@3.14.9/dist/module.esm.js'
Alpine.plugin(PineconeRouter)
Usage Examples
Basic SPA with Inline Templates
<div x-data="app">
<template x-route="/" x-template>
<h1>Welcome!</h1>
<p>Your name?</p>
<input @keydown.enter="$router.navigate('/'+$el.value)">
</template>
<template x-route="/:name" x-handler="greetHandler" x-template>
<h1>Hello <span x-text="$params.name"></span>!</h1>
<button @click="$history.back()">Go Back</button>
</template>
<template x-route="notfound" x-template>
<h1>Page Not Found</h1>
</>
External Templates with Preloading
<div x-data="app">
<template x-route="/" x-template.preload="/views/home.html"></template>
<template x-route="/profile/:id" x-template="/views/profile.html"></template>
<template x-route="notfound" x-template.preload="/views/404.html"></template>
</div>
<script>
document.addEventListener('alpine:init', () => {
window.PineconeRouter.settings({
targetID: 'app',
})
})
</script>
<div id="app"></div>
Async Handler with Data Passing
<template x-route="/posts" x-handler="[fetchPosts, renderPosts]" x-template="/views/posts.html"></template>
<script>
Alpine.data('app', () => ({
async fetchPosts(ctx, controller) {
const response = await fetch('/api/posts', { signal: controller.signal })
return await response.json()
},
renderPosts(ctx) {
console.table(ctx.data)
},
}))
</script>
Loading Events with nProgress
document.addEventListener('pinecone:start', () => NProgress.start())
document.addEventListener('pinecone:end', () => NProgress.done())
document.addEventListener('pinecone:fetch-error', (e) => console.error(e.detail))
