@nabla/vite-plugin-eslint

Plugs ESLint into Vite dev server.

Differences with vite-plugin-eslint

• Keeps HMR fast: linting is done asynchronously and doesn't block the transform process
• Reduces noise: Display results via console logs

Because of this, the plugin can't fail the build and is only applied in dev. Like typechecking, linting should be done before or in parallel of the build command.

Install

yarn add --dev @nabla/vite-plugin-eslint

Usage

import { defineConfig } from "vite";
import eslintPlugin from "@nabla/vite-plugin-eslint";

export default defineConfig({
  plugins: [eslintPlugin()],
