slugify('  Déjà Vu!  ');
//=> 'deja-vu'

slugify('fooBar 123 $#%');

API

slugify(input, [options])

input

Type: string

options

Type: Object

separator

Type: string Default: -

slugify('BAR and baz');
//=> 'bar-and-baz'

slugify('BAR and baz', {separator: '_'});
//=> 'bar_and_baz'

lowercase

Type: boolean Default: true

Make the slug lowercase.

slugify('Déjà Vu!');
//=> 'deja-vu'

slugify('Déjà Vu!', {lowercase: false});
//=> 'Deja-Vu'

decamelize

Type: boolean Default: true

Convert camelcase to separate words. Internally it does fooBar → foo bar.

slugify('fooBar');
//=> 'foo-bar'

slugify('fooBar', {decamelize: false});
//=> 'foobar'

customReplacements

Type: Array<string[]> Default: [ ['&', ' and '], ['🦄', ' unicorn '], ['♥', ' love '] ]

Specifying this only replaces the default if you set an item with the same key, like &. The replacements are run on the original string before any other transformations.

slugify('Foo@unicorn', {
	customReplacements: [
		['@', 'at']
	]
});
//=> 'fooatunicorn'

Add a leading and trailing space to the replacement to have it separated by dashes:

slugify('foo@unicorn', {
	customReplacements: [
		['@', ' at ']
	]
});
//=> 'foo-at-unicorn'
