Permix

Permix is a lightweight, framework-agnostic, type-safe permissions management library for JavaScript applications on the client and server sides.

Documentation

You can find the documentation here.

Example

To quick start you only need to write the following code:

import { createPermix } from 'permix'

const permix = createPermix<{
  post: ['read']
}>()

permix.setup({
  post: {
    read: true,
  },
})

permix.check('post.read') // true

Permix has other powerful features, so here's check out the docs or the examples directory.

AI agents

Your agents know every permission in place: the whole permission model lives in one typed createPermix<...> schema, and any permission an agent invents, misspells, or forgets is a TypeScript error.

• Agent skills ship inside the npm package — npx skills add letstri/permix, or copy them from node_modules/permix/skills/ so they match your installed version.
• LLM-friendly docs: llms.txt, llms-full.txt, and any docs page as Markdown by appending .md to its URL.
• Prompts, AGENTS.md conventions, and gating in-app AI tools: AI Agents guide.
