What it is

Radix Primitives is an open-source, low-level React UI component library focused on accessibility and customization. It provides unstyled, composable components (accordion, dialog, dropdown-menu, checkbox, etc.) designed as building blocks for design systems and web applications, allowing teams to build high-quality accessible UIs without reimplementing ARIA patterns. Monorepo organized as: internal/ contains shared build tooling (builder/, test-data/, test-utils/, typescript-config/) and apps/ssr-testing/ contains a Next.js application with per-component test pages (accordion/, dialog/, checkbox/, etc.). Core component packages are likely in packages/ directory (not fully listed), with…

Start here

Open these first:

• internal/builder/builder.js — Core build system entry point that compiles and bundles UI primitives for distribution.
• internal/builder/radix-build.js — CLI tool that orchestrates the build pipeline for all primitive components.
• internal/typescript-config/react-library.json — TypeScript configuration baseline for all React primitive packages in the monorepo.
• internal/test-utils/ref-stability.tsx — Shared testing utilities ensuring ref consistency across primitive components.
• apps/ssr-testing/app/layout.tsx — Root layout for SSR validation app that tests server-side rendering compatibility of all primitives.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/radix-ui/primitives.git
cd primitives
npm install -g pnpm
pnpm install

Note: README explicitly requires pnpm, not npm or yarn.

Daily commands:

Exact run command cannot be inferred from provided data (no root package.json shown, no Makefile, no pnpm scripts visible). Verify the root package.json for 'dev' or 'build' scripts, or check internal/builder/radix-buil…

Key cautions & unknowns

• Small team — 4 contributors active in recent commits
• Single-maintainer risk — top contributor 95% of recent commits
• pnpm is mandatory (not npm or yarn); README explicitly installs it globally before dependencies. Root package.json structure not fully visible — verify workspaces configuration before attempting to add packages. Build…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
