Preact

Use Preact support from the lean v3 composer. Install the @santi020k/eslint-config-preact package.

Install

pnpmnpmYarnBun

bash

pnpm add -D @santi020k/eslint-config-basic @santi020k/eslint-config-preact eslint

bash

npm install -D @santi020k/eslint-config-basic @santi020k/eslint-config-preact eslint

bash

yarn add -D @santi020k/eslint-config-basic @santi020k/eslint-config-preact eslint

bash

bun add -d @santi020k/eslint-config-basic @santi020k/eslint-config-preact eslint

Configure

import { defineConfig } from '@santi020k/eslint-config-basic'

export default await defineConfig({
  frameworks: {
    preact: true
  },
  typescript: true
})

With the required config packages installed, the one-line recommended entry auto-detects the framework; custom configs can use defineConfig() without a frameworks object.

What It Adds

• Preact component and Hooks rules.
• Preact JSX pragmas (h and Fragment) are automatically configured in ESLint to avoid errors for undefined variables.
• Composition through the same @santi020k/eslint-config-basic entry point as every other framework.
• Compatibility with advanced overrides if you pass a custom config array or factory instead of true.

Notes

• This framework package is a public, optional dependency in v3; the basic composer loads it only when enabled.
