Reminist

💡 About

Blazing fast, zero-dependency, TypeScript-native router for any environment.

Reminist is a high-performance routing library built with TypeScript. It uses an optimized Radix Tree structure where lookup speed is proportional to the length of the route path, not the total number of routes. This makes route resolution incredibly fast and scalable, especially for high-throughput environments where every microsecond counts.

🚀 Key Features

• Exceptional Performance: Lookups are independent of the number of routes. Performance depends only on the length of the path, ensuring consistent speed regardless of your application's size.
• Type-Safe by Design: Written entirely in TypeScript for a great developer experience.
• Zero Dependencies: Lightweight and easy to integrate into any project.
• Flexible Route Patterns: Full support for static, dynamic, wildcard, and catch-all routes.
• Environment Agnostic: Works seamlessly in Node.js, Bun, Deno, and modern browsers.
• Path Caching: Automatically caches processed URL paths to avoid redundant string manipulation.

📦 Installation

You can install reminist using your preferred package manager:

bun add reminist

(Works with npm, yarn, or pnpm as well)

🏁 Getting Started

Here's a quick example to get you up and running:

import { Reminist } from 'reminist'

const router = new Reminist({ keys: ['GET'] })
  .add('GET', '/users/:id', { handler: (userId: string) => console.log(`User fetched: ${userId}`) })

const result = router.find('GET', '/users/10')
if (result.node) {
  console.log('User Id:', result.params) // { id: '10' }

  result.node.store.handler(result.params.id) // User fetched: 10
}

🛣️ Route Syntax

Reminist supports several common routing patterns.

Type	Syntax	Example	Description
Static	/path/to/page	/about/contact	Matches the exact path. The fastest type of route.
Dynamic	/:param	/users/:id	Matches any segment and captures its value in params.
Wildcard	*	/assets/*	A standalone * consumes the rest of the URL. The captured value is available in params['*'].
Catch-All	/[...param]	/files/[...filePath]	Captures all remaining segments as a single value in params.
Optional Catch-All	/[[...param]]	/docs/[[...slug]]	Behaves like a catch-all but also matches the route if no further segments are provided.
