longmo-lint-configs

1.0.17 verified Fri May 01 auth: no javascript

A unified linter configuration package for Vue 2/3 projects, providing preconfigured ESLint, Prettier, Stylelint, and JSConfig setups. Version 1.0.17, updated frequently via GitHub. Key differentiators: supports both Vue 2 and Vue 3 with flat ESLint config (ESLint v9+), includes TypeScript support, and relies on peer dependencies kept external to minimize bundle size (36.9 kB). Requires manual installation of many peer deps; recommended for teams wanting a single source of lint configs.

Common errors

error Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'eslint-plugin-vue' ↓

cause Missing peer dependency 'eslint-plugin-vue' not installed.

fix

Install the missing peer dep: pnpm add -D eslint-plugin-vue vue-eslint-parser

error SyntaxError: Unexpected token 'export' (or 'import' not found) in eslint.config.mjs ↓

cause Config file uses ESM syntax but Node is not configured for ESM.

fix

Set "type": "module" in package.json, or rename file to .mjs.

error Error: Cannot find module 'longmo-lint-configs/eslint-config' ↓

cause Import path is wrong; likely tried to import from 'longmo-lint-configs' top-level.

fix

Use subpath import: import { defineConfig } from 'longmo-lint-configs/eslint-config'

Warnings

breaking ESLint config uses flat config format (ESLint v9+). Does not work with ESLint v8 or .eslintrc files. ↓

fix Upgrade ESLint to v9 and use eslint.config.mjs (or .js). Convert any legacy .eslintrc configs.

gotcha Many peer dependencies are not bundled; you must install them manually. If missing, imports fail at runtime. ↓

fix Run: pnpm add -D eslint @eslint/js eslint-plugin-vue vue-eslint-parser eslint-plugin-import-x eslint-plugin-prettier prettier stylelint (see README for full list).

gotcha Vue 2 projects require extra rules (e.g., vue/no-multiple-template-root). Not automatically detected. ↓

fix Add Vue 2 specific rules in your eslint.config.mjs override block.

deprecated Version 1.0.0 used require() syntax; now ESM only. ↓

fix Use import statements with .mjs extension for config files.

export default defineConfig([{
  rules: {
    'no-console': 'warn',
    'vue/multi-word-component-names': 'off',
  },
}]);
