@y0hami/eslint-config

Shared ESLint flat configs.

All presets include eslint-config-prettier to disable rules that conflict with Prettier. Run Prettier separately to format files.

JavaScript and TypeScript filenames and their source directories must use kebab-case. Common generated output directories are ignored.

All presets include the recommended security rules. The TypeScript preset uses typed linting and requires source files to be included by a tsconfig.json.

Base

import { defineConfig } from 'eslint/config'
import base from '@y0hami/eslint-config/base'

export default defineConfig(base)

React

import { defineConfig } from 'eslint/config'
import react from '@y0hami/eslint-config/react'

export default defineConfig(react)

TypeScript

Three entry points are published: ./typescript6 for projects on the classic (TS6-compatible) compiler, ./typescript7 for projects building with TypeScript 7, and ./typescript, an alias for whichever of the two is current (./typescript7 today). Prefer ./typescript6 or ./typescript7 explicitly if you don't want the alias's target to change out from under you in a future release.

The rulesets are identical — typescript-eslint's type-aware rules require TypeScript's programmatic API, which TS7 doesn't ship until 7.1, so linting still runs against a TS6-compatible typescript package either way. This isn't specific to typescript-eslint: ts-jest, ts-morph, and framework compilers (Vue, Angular, Svelte) all have the same peer dependency on the classic API, so the fix has to work for all of them at once, not just ESLint.

If your project builds with TypeScript 7, keep the typescript package name aliased to Microsoft's TS6 compatibility package, and install TS7 itself under a separate name for the actual build step:

npm install -D typescript@npm:@typescript/typescript6 @typescript/native@npm:typescript@^7

Every tool that does require('typescript') — ESLint included — keeps working unchanged, while your build/typecheck scripts invoke TS7 explicitly through @typescript/native's binary instead of the ambient typescript one.

import { defineConfig } from 'eslint/config'
import typescript from '@y0hami/eslint-config/typescript'

export default defineConfig(typescript)

For React with TypeScript, compose both configs:

import { defineConfig } from 'eslint/config'
import react from '@y0hami/eslint-config/react'
import typescript from '@y0hami/eslint-config/typescript6'

export default defineConfig(typescript, react)
