zART-Stack 🤯

Zero-API, React, & TypeScript

⚡️ Probably the fastest way to build a React Native app with your own backend ⚡️

Introduction

A monorepo containing:

• Next.js web app
• React Native app with Expo
• A tRPC-API which is inferred straight into the above.
• Prisma as a typesafe ORM

In tRPC you simply write API-functions that are automatically inferred straight into your frontend - no matter if it's React, React Native, or something else (that is TS/JS-based).

Very rough video recorded in 2 minutes 😅

Requirements

You will need docker compose to run the postgres database. It comes with the Docker Desktop App

Getting started

git clone git@github.com:KATT/zart.git
cd zart
yarn
yarn dev

Press i after yarn dev in to launch the iOS Simulator.

Now - head over to one of the ./apps, whilist updating a router in tRPC or the Database Schema and see that the data is directly inferred.

Available commands

Command	Description
yarn dev	Starts Postgres, Expo & Next.js
yarn db-up	Starts Postgres on port 5466
yarn db-migrate-dev	Runs the latest Database migrations after updating the Prisma schema
yarn db-nuke	Stops and deletes the the database
