[bug] insert custom ESlint rules in eslint.config.ts can not work

[gaomingzhao666]

Hey, everyone.

I created a simple skeleton vue3/vite app with a little bit basic component Header.vue and Navbar.vue, and the rule multi-word-component-names is set as error as default, so the Header.vue actually throwed a error, I want to change the rule as off, here is my code in eslint.config.ts:

❌can not work

import { globalIgnores } from 'eslint/config'
import { defineConfigWithVueTs, vueTsConfigs } from '@vue/eslint-config-typescript'
import pluginVue from 'eslint-plugin-vue'
import skipFormatting from '@vue/eslint-config-prettier/skip-formatting'

// To allow more languages other than `ts` in `.vue` files, uncomment the following lines:
// import { configureVueProject } from '@vue/eslint-config-typescript'
// configureVueProject({ scriptLangs: ['ts', 'tsx'] })
// More info at https://github.com/vuejs/eslint-config-typescript/#advanced-setup

export default defineConfigWithVueTs(
  {
    name: 'app/files-to-lint',
    files: ['**/*.{ts,mts,tsx,vue}'],
  },
    // custom eslint rules
  {
    rules: {
      'vue/multi-word-component-names': 'off',
    },
  },

  globalIgnores(['**/dist/**', '**/dist-ssr/**', '**/coverage/**']),

  pluginVue.configs['flat/essential'],
  vueTsConfigs.recommended,
  skipFormatting,
)

The code above can not work properly, and I found it's only be work properly when I put the custom rules object in ABOSOLUTE RIGHT back to vueTsConfigs.recommended as the code below after I searched something on Google:

✔can work

import { globalIgnores } from 'eslint/config'
import { defineConfigWithVueTs, vueTsConfigs } from '@vue/eslint-config-typescript'
import pluginVue from 'eslint-plugin-vue'
import skipFormatting from '@vue/eslint-config-prettier/skip-formatting'

// To allow more languages other than `ts` in `.vue` files, uncomment the following lines:
// import { configureVueProject } from '@vue/eslint-config-typescript'
// configureVueProject({ scriptLangs: ['ts', 'tsx'] })
// More info at https://github.com/vuejs/eslint-config-typescript/#advanced-setup

export default defineConfigWithVueTs(
  {
    name: 'app/files-to-lint',
    files: ['**/*.{ts,mts,tsx,vue}'],
  },

  globalIgnores(['**/dist/**', '**/dist-ssr/**', '**/coverage/**']),

  pluginVue.configs['flat/essential'],
  vueTsConfigs.recommended,

  // custom eslint rules
  {
    rules: {
      'vue/multi-word-component-names': 'off',
    },
  },
  skipFormatting,
)

Must be right back of vueTsConfigs.recommended can be work, even in back of but not right back of can not work like the code below:

❌ can not work

import { globalIgnores } from 'eslint/config'
import { defineConfigWithVueTs, vueTsConfigs } from '@vue/eslint-config-typescript'
import pluginVue from 'eslint-plugin-vue'
import skipFormatting from '@vue/eslint-config-prettier/skip-formatting'

// To allow more languages other than `ts` in `.vue` files, uncomment the following lines:
// import { configureVueProject } from '@vue/eslint-config-typescript'
// configureVueProject({ scriptLangs: ['ts', 'tsx'] })
// More info at https://github.com/vuejs/eslint-config-typescript/#advanced-setup

export default defineConfigWithVueTs(
  {
    name: 'app/files-to-lint',
    files: ['**/*.{ts,mts,tsx,vue}'],
  },

  globalIgnores(['**/dist/**', '**/dist-ssr/**', '**/coverage/**']),

  pluginVue.configs['flat/essential'],
  vueTsConfigs.recommended,
  skipFormatting,

    // custom eslint rules
  {
    rules: {
      'vue/multi-word-component-names': 'off',
    },
  },
)
