π These are my settings for TypeScript / ESLint / Prettier in a project, also support mono / esm π¦
These are the ESLint and Prettier settings for a Next.js project β‘οΈ
- Lints JavaScript / TypeScript based on the latest standards
- Multiple configs
react
hooks
next
.. - Shared
tsconfig.json
- Fixes issues and formatting errors with Prettier
- Check for accessibility rules on JSX elements.
-
If you don't already have a
package.json
file, create one withnpm init
. -
Then we need to install the config:
npm i -D @hyperse/eslint-config-hyperse
- Create a
eslint.config.js
file in the root of your project's directory (it should live where package.json does). Youreslint.config.js
file should look like this: - if you are using
commonjs
, just changeeslint.config.js
toeslint.config.mjs
- Extends your config with the minimal base of
@hyperse
config :
import { base, defineConfig } from '@hyperse/eslint-config-hyperse';
export default defineConfig([
// ...typescript
...base,
{
rules: {
'@typescript-eslint/no-explicit-any': 'off',
},
},
]);
you can write you tsconfig.json
via extends @hyperse/eslint-config-hyperse/tsconfig.base.json
{
"$schema": "https://json.schemastore.org/tsconfig",
"extends": "@hyperse/eslint-config-hyperse/tsconfig.base.json",
"compilerOptions": {
"baseUrl": "./",
"rootDir": ".",
"outDir": "dist",
"types": ["vitest/globals"],
"paths": {}
},
"include": ["next-env.d.ts", "**/*.ts", "**/*.tsx"]
}
write you tsconfig.build.json
as below
{
"extends": "./tsconfig.json",
"compilerOptions": {
"outDir": "./dist",
"rootDir": "./src",
"baseUrl": "./",
"incremental": false,
"paths": {}
},
"exclude": ["**/*.stories.tsx", "**/*.stories.mdx", ".storybook/**", "dist"]
}
You can add two scripts to your package.json to lint and/or fix your code:
{
"scripts": {
"lint": "tsc --noEmit && eslint .",
"lint:fix": "npm run lint -- --fix"
}
}
{
"scripts": {
"lint": "eslint .",
"lint:fix": "npm run lint -- --fix"
}
}
You can also add additional rules for Next.js
import { defineConfig, nextjs } from '@hyperse/eslint-config-hyperse';
export default defineConfig([
// ...typescript
...nextjs,
{
rules: {
'@typescript-eslint/no-explicit-any': 'off',
},
},
]);
You can also add additional rules for only React.js ecosystem (without Next.js).
import { defineConfig, reactjs } from '@hyperse/eslint-config-hyperse';
export default defineConfig([
// ...typescript
...reactjs,
{
rules: {
'@typescript-eslint/no-explicit-any': 'off',
},
},
]);
Once you have done. You probably want your editor to lint and fix for you.
- Install the ESLint package
- Now we need to setup some VS Code settings. Create a
.vscode
folder at your root project, and create asettings.json
file in this folder. Then, add this little config:
{
"editor.formatOnSave": true,
"editor.defaultFormatter": "dbaeumer.vscode-eslint",
"editor.codeActionsOnSave": {
"source.fixAll": "explicit",
"source.organizeImports": "never"
},
"[jsonc]": {
"editor.formatOnSave": false
},
"[json]": {
"editor.formatOnSave": false
}
}
we need to disable vscode editor language formatter for json, jsonc
{
"[jsonc]": {
"editor.formatOnSave": false
},
"[json]": {
"editor.formatOnSave": false
}
}
