toss/granite — Enterprise-grade React Native framework for microservice apps.

Description and use

**Brief Summary (2‑3 sentences)**
toss/granite is an enterprise‑grade React Native framework designed for microservice‑based mobile apps. It delivers lightweight (≈200 KB) bundles, a set of reusable UI components, and built‑in AWS‑ready infrastructure, making it brownfield‑friendly for teams that need to accelerate front‑end delivery while reusing existing services.

**Value**

• **Speed to market:** Pre‑crafted, theme‑able components let developers ship product‑facing screens with far less custom UI code.
• **Consistency & reuse:** A shared component library encourages uniform design language across multiple micro‑frontends, reducing duplication and maintenance overhead.
• **Infrastructure alignment:** Out‑of‑the‑box AWS integration (e.g., Cognito, AppSync, Lambda) streamlines the bridge between the mobile UI and backend services.

**Practical Adoption Path**

1. **Pilot integration:** Clone the repo, run the sample app, and compare its component API with the UI patterns of an existing microservice.
2. **Manual metadata review:** Because discovery signals are sparse, perform a code audit to verify compatibility with your current navigation, state‑management, and styling conventions.
3. **Component migration:** Replace a small, non‑critical screen with Granite components, adjusting any custom theming as needed.
4. **Incremental rollout:** Gradually expand the substitution to other screens, leveraging Granite’s AWS helpers for authentication, API calls, and analytics.
5. **Governance checklist:** Confirm license compliance, run security scans (e.g., Snyk), and lock dependency versions before merging to main.

**Production Readiness**

• **Maturity:** Medium – the framework is solid enough for prototypes, internal tools, or staged rollouts, but it still requires dependency vetting and ongoing maintenance.
• **Signals:** 455 GitHub stars, recent activity (last commit 2026‑05‑12), and TypeScript codebase indicate an active community, yet the lack of extensive integration metadata means you should conduct a thorough review before full production use.
• **Risk considerations:** Verify the project’s license, perform security audits, and ensure that maintainers are responsive to issues; once these checks pass, Granite can be promoted to production for customer‑facing mobile apps.

Problem

toss/granite helps ship user-facing interfaces with less custom UI work.

Outcome

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.

Workflow

• build product UI faster
• reuse interface components
• improve frontend delivery
