In my Gatsby (React) project I am using typescript. I need to setup ESLint and have to use eslint-config-airbnb-typescript
I am also using Prettier:
prettier
(comes with Gatsby), and I installed the following packages:
npm install eslint-config-prettier eslint-plugin-prettier --save-dev
If I look at the documentation of eslint-config-airbnb-typescript, I don't see anything about the @typescript-eslint/parser package?
They showing an example like:
module.exports = {
extends: ['airbnb-typescript'],
parserOptions: {
project: './tsconfig.json',
}
};
What's the correct way? And in their example, you don't have to use the @typescript-eslint/parser
package?
My ESLint config .eslintrc.js
:
module.exports = {
globals: {
__PATH_PREFIX__: true,
},
env: {
browser: true,
es6: true,
},
plugins: ['react', '@typescript-eslint', 'prettier'],
extends: [
'airbnb-typescript',
'airbnb/hooks',
'plugin:@typescript-eslint/recommended',
'prettier',
'prettier/react',
'prettier/@typescript-eslint',
'plugin:prettier/recommended',
],
parser: '@typescript-eslint/parser',
parserOptions: {
ecmaFeatures: {
jsx: true,
},
ecmaVersion: 2018,
sourceType: 'module',
project: './tsconfig.json',
},
rules: {
'prettier/prettier': [
'error',
{
endOfLine: 'auto',
},
],
},
};
My tsconfig.js
:
{
"compilerOptions": {
"module": "commonjs",
"target": "esnext",
"jsx": "preserve",
"lib": ["dom", "es2015", "es2017"],
"strict": true,
"noEmit": true,
"isolatedModules": true,
"esModuleInterop": true,
"skipLibCheck": true,
"noUnusedLocals": true,
"noUnusedParameters": true,
"removeComments": false,
"preserveConstEnums": true,
"baseUrl": "src"
},
"include": ["src/**/*"]
}
This is the way I set it up in eslint-config-auto, which automatically configures eslint based on your package.json config.
overrides: [
{
files: ['**.ts', '**.tsx'],
parser: '@typescript-eslint/parser',
parserOptions: {
project: './tsconfig.json',
},
},
],
