I have been working on setting up linting & formatting for my React Native project for a couple of weeks now, but I'm unable to make much progress. I have looked at many tutorials and followed them as much as I could, but there still seems to be some setup problems.
My project has a Django backend and React Native frontend, therefore the React app (in src/frontend
directory) started using the tutorial here using Expo, Yarn and TypeScript: https://reactnative.dev/docs/environment-setup.
No further changes were made to this setup, and I attempted to add ESLint & Prettier to it.
These are my configuration files:
.eslintrc.js
module.exports = { parser: '@typescript-eslint/parser', parserOptions: { project: 'tsconfig.json', tsconfigRootDir: __dirname, }, plugins: ['@typescript-eslint','import','react','react-hooks','react-native','prettier', ], extends: ['airbnb-typescript','plugin:import/recommended','plugin:import/typescript','plugin:react/recommended','plugin:react-hooks/recommended','prettier','plugin:prettier/recommended', ], rules: {'no-use-before-define': 'off','@typescript-eslint/no-use-before-define': ['error'],'prettier/prettier': 'error', },};
.prettierrc.json
{"singleQuote": true}
tsconfig.json
{"extends": "expo/tsconfig.base","compilerOptions": {}}
To name a few significant errors I am getting, I get import/namespace
for react-native
where it says ';' expected
, variable used before definition such as styles
, and parsing error "parserOptions.project" has been set for @typescript-eslint/parser
and .eslintrc.js
does not match the project config.
