newline-after-import

Enforces having one or more empty lines after the last top-level import statement or require call. +(fixable) The --fix option on the [command line] automatically fixes problems reported by this rule.

Rule Details

This rule has one option, count which sets the number of newlines that are enforced after the last top-level import statement or require call. This option defaults to 1.

Valid:

import defaultExport from './foo'

const FOO = 'BAR'

import defaultExport from './foo'
import { bar }  from 'bar-lib'

const FOO = 'BAR'

const FOO = require('./foo')
const BAR = require('./bar')

const BAZ = 1

Invalid:

import * as foo from 'foo'
const FOO = 'BAR'

import * as foo from 'foo'
const FOO = 'BAR'

import { bar }  from 'bar-lib'

const FOO = require('./foo')
const BAZ = 1
const BAR = require('./bar')

With count set to 2 this will be considered valid:

import defaultExport from './foo'


const FOO = 'BAR'

With count set to 2 these will be considered invalid:

import defaultExport from './foo'
const FOO = 'BAR'

import defaultExport from './foo'

const FOO = 'BAR'
