🤓 lint-react-native-app

A command-line interface that adds linting and prettier to a react / react-native project. It primarily targets expo.

Originally inspired by this article with additions to cover pieces it misses.

Install

Run this after running expo init (or from react-native cli):

$ npx lint-react-native-app

This will create a .prettierrc.json and .eslintrc.json file for you.

It supports TypeScript, React Hooks linters, and other recommended react / react-native linter dependencies.
