Introduction

Monospace is a monorepo for developing FiveM NUI (Native UI) interfaces. Built with Bun, Turborepo, Preact, Vite, and Tailwind CSS, it provides shared configurations, UI utilities, and a consistent development workflow across multiple NUI projects.

Why Monospace?

Building FiveM NUI interfaces often involves repetitive setup — configuring bundlers, linters, TypeScript, and styling for each project. Monospace solves this by centralizing everything into a single monorepo with shared packages:

• Consistent tooling — Every NUI app shares the same Vite, Tailwind, TypeScript, and Biome configurations.
• Shared UI library — Reusable Preact components and FiveM-specific utilities like fetchNui, useEvent, and the expose system.
• Fast builds — Turborepo caches and parallelizes builds across all apps.
• Type safety — Full TypeScript support with strict mode and Zod schema validation for NUI events.
