How to remove newline between import groups?

Thanks for nice plugin!

I tried to use this and had one question. How to remove newline between import groups? (Or is there no option to remove line breaks?)

import fetch from 'cross-fetch'
import { NextPage } from 'next'
import Link from 'next/link'
import React from 'react'

// I want to delete ↑ line...
import { Head } from '~/components/abstracts/head'

The config file used is shown below.

My ESLint config

  "root": true,
  "env": {
    "es6": true,
    "node": true,
    "browser": true

@keemor Hi!

You need to put everything in the same array, like this:

{
  "plugins": ["simple-import-sort"],
  "extends": "react-app",
  "rules": {
    "simple-import-sort/sort": [
      "warn",
      {
        "groups": [
          [
            // Packages. `react` related packages come first.
            "^react",
            "^@?\\w",
            // Internal packages.
            "^(components|modules|utils)(/.*|$)",
            // Side effect imports.
            "^\\u0000",
            // Parent imports. Put `..` last.
            "^\\.\\.(?!/?$)", "^\\.\\./?$",
            // Other relative imports. Put same-folder imports and `.` last.
            "^\\./(?=.*/)(?!/?$)", "^\\.(?!/?$)", "^\\./?$",
            // Style imports.
            "^.+\\.s?css$"
          ]
        ]
      }
    ],
    "import/first": "warn",
    "import/newline-after-import": "warn",
    "import/no-duplicates": "warn",
  }
}

(I didn’t test that before posting, so forgive me if I made a mistake 🙏)

This is now possible in v5.0.0 using custom grouping.

For example:

{
  "rules": {
    "simple-import-sort/imports": [
      "error",
      {
        "groups": [["^\\u0000", "^@?\\w", "^[^.]", "^\\."]]
      }
    ]
  }
}
