For more control over which rules apply to your Svelte files, you apply overrides like this:

```js
// eslint.config.js
import { antfu, svelte, typescript } from '@antfu/eslint-config'

export default antfu(
{},
typescript({
componentExts: ['svelte'],
}),
svelte({
typescript: true,
overrides: {
'svelte/no-dom-manipulating': 'error',
},
}),

I would not suggest users to directly use those sub configs manually to overrides,

  • It's easy to duplicate configs, for example, here typescript will be created twice with the order messed up
  • You need to know very well how each config work, and duplicated the information like having svelte in ts, and ts in svelte. Could be hard to keep track on it.

Instead, I'd recommend to use the generalized composer: https://github.com/antfu/eslint-config#config-composer

Where you can override, or replace an entire config item as you want.

Ok, I updated it to accomplish my overrides via the config composer option so now the Typescript stuff is not duplicated. The Svelte stuff was never duplicated the old way but perhaps it's best to keep it uniform by doing all the overrides this way. Did I do it right this time? 馃槃

So you can see my full example, using the strategy suggested in my pr here, I now have this:

import { antfu } from '@antfu/eslint-config'
import svelteStylistic from 'eslint-plugin-svelte-stylistic'

export default antfu(
  {
    ignores: [
      '**/.svelte-kit**',
      '.eslintcache',
      '**/route/kitbook/**',
    ],
    stylistic: {
      overrides: {
        'style/brace-style': ['error', '1tbs', { allowSingleLine: true }],
      },
    },
    svelte: true,
  },
  {

    files: ['**/*.svelte', '**/*.composition'],
    plugins: {

      'svelte-stylistic/consistent-attribute-lines': 'error',
    },
  },

As a bit of general feedback on your docs, it's hard to keep track of and know how to use the different overrides options. For vue and typescript (but not svelte) you can provide them directly in the integrations:

vue: {
  overrides: {
    'vue/operator-linebreak': ['error', 'before'],
  },
},
typescript: {
  overrides: {
    'ts/consistent-type-definitions': ['error', 'interface'],
  },
},

You can provide them as a new ruleset, and then finally using the Config Composer. The section on Config Composer I completely didn't understand the first time reading through. A tip there about getting names from the config inspector would be helpful.

Now finally, after reflecting on everything it seems that if I didn't have my special .composition extension, I could have just done things like this:

export default antfu(
  {
    svelte: true,
  },
  {
    files: ['**/*.svelte'],
    rules: {
      'svelte/no-dom-manipulating': 'error',
    },
  },
).overrides({
  'antfu/typescript/rules': {
    files: ['**/*.svelte'],
    rules: {
      'prefer-destructuring': 'error',
    },
  },
})

Want me to use that method in my doc update instead?

Running `npx eslint` should prompt you to install the required dependencies, otherwise, you can install them manually:
