Vertex

Overview

Vertex is a production-ready starter for banking and fintech apps built on Expo. It ships with a reactive Zustand state layer and a reusable UI component library, so you can wire up real screens instead of re-building infrastructure from scratch.

Why Vertex

• Reactive state layer powered by Zustand: predictable, minimal-boilerplate stores instead of prop drilling or Context soup.
• Reusable UI component library: buttons, cards, inputs and sheets built once and shared across every screen.
• Reanimated-driven interactions: transitions and gestures that run on the native thread and stay smooth at 60fps.
• Skia for custom graphics: draw charts and financial visuals that a stock <Image> can't do.
• Expo Router for navigation: file-based, typed routes with nested layouts out of the box.
• Strict TypeScript throughout: state, components and navigation are all fully typed.

Tech stack

Every dependency earns its place:

• Expo: managed workflow with a fast path to TestFlight and Play builds.
• Expo Router: file-based, typed navigation with nested layouts.
• TypeScript: strict typing across state, components and screens.
• Zustand: lightweight, reactive global state without Redux ceremony.
• Reanimated: native-thread gesture and transition animations.
• Skia: custom-drawn charts and graphics for financial data.

Getting started

Project structure

A conventional Expo Router layout, so you can find your way around in minutes:

• app/: file-based routes and layouts
• components/: the shared, reusable UI library
• store/: Zustand stores for app state
• assets/: fonts, icons and images
