# camelcase

> Convert a dash/dot/underscore/space separated string to camelCase or PascalCase: `foo-bar` → `fooBar`

Correctly handles Unicode strings.

If you use this on untrusted user input, don't forget to limit the length to something reasonable.

## Install

```
$ npm install camelcase
```

*If you need to support Firefox < 78, stay on version 5 as version 6 uses regex features not available in Firefox < 78.*

## Usage

```js
const camelCase = require('camelcase');

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

camelCase('foo_bar');
//=> 'fooBar'

camelCase('Foo-Bar');
//=> 'fooBar'

camelCase('розовый_пушистый_единорог');
//=> 'розовыйПушистыйЕдинорог'

camelCase('Foo-Bar', {pascalCase: true});
//=> 'FooBar'

camelCase('--foo.bar', {pascalCase: false});
//=> 'fooBar'

camelCase('Foo-BAR', {preserveConsecutiveUppercase: true});
//=> 'fooBAR'

camelCase('fooBAR', {pascalCase: true, preserveConsecutiveUppercase: true}));
//=> 'FooBAR'

camelCase('foo bar');
//=> 'fooBar'

console.log(process.argv[3]);
//=> '--foo-bar'
camelCase(process.argv[3]);
//=> 'fooBar'

camelCase(['foo', 'bar']);
//=> 'fooBar'

camelCase(['__foo__', '--bar'], {pascalCase: true});
//=> 'FooBar'

camelCase(['foo', 'BAR'], {pascalCase: true, preserveConsecutiveUppercase: true})
//=> 'FooBAR'

camelCase('lorem-ipsum', {locale: 'en-US'});
//=> 'loremIpsum'
```

## API

### camelCase(input, options?)

#### input

Type: `string | string[]`

String to convert to camel case.

#### options

Type: `object`

##### pascalCase

Type: `boolean`\
Default: `false`

Uppercase the first character: `foo-bar` → `FooBar`

##### preserveConsecutiveUppercase

Type: `boolean`\
Default: `false`

Preserve the consecutive uppercase characters: `foo-BAR` → `FooBAR`.

##### locale

Type: `false | string | string[]`\
Default: The host environment’s current locale.

The locale parameter indicates the locale to be used to convert to upper/lower case according to any locale-specific case mappings. If multiple locales are given in an array, the best available locale is used.

```js
const camelCase = require('camelcase');

camelCase('lorem-ipsum', {locale: 'en-US'});
//=> 'loremIpsum'

camelCase('lorem-ipsum', {locale: 'tr-TR'});
//=> 'loremİpsum'

camelCase('lorem-ipsum', {locale: ['en-US', 'en-GB']});
//=> 'loremIpsum'

camelCase('lorem-ipsum', {locale: ['tr', 'TR', 'tr-TR']});
//=> 'loremİpsum'
```

Setting `locale: false` ignores the platform locale and uses the [Unicode Default Case Conversion](https://unicode-org.github.io/icu/userguide/transforms/casemappings.html#simple-single-character-case-mapping) algorithm:

```js
const camelCase = require('camelcase');

// On a platform with 'tr-TR'

camelCase('lorem-ipsum');
//=> 'loremİpsum'

camelCase('lorem-ipsum', {locale: false});
//=> 'loremIpsum'
```
