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.
npm install camelcaseimport camelCase from 'camelcase';
camelCase('foo-bar');
//=> 'fooBar'
camelCase('foo_bar');
//=> 'fooBar'
camelCase('Foo-Bar');
//=> 'fooBar'
camelCase('розовый_пушистый_единорог');
//=> 'розовыйПушистыйЕдинорог'
camelCase('foo bar');
//=> 'fooBar'
console.log(process.argv[3]);
//=> '--foo-bar'
camelCase(process.argv[3]);
//=> 'fooBar'
camelCase(['foo', 'bar']);
//=> 'fooBar'
camelCase(['__foo__', '--bar']);
//=> 'fooBar'Type: string | string[]
The string to convert to camel case.
Type: object
Type: boolean
Default: false
Uppercase the first character: foo-bar → FooBar
import camelCase from 'camelcase';
camelCase('foo-bar', {pascalCase: true});
//=> 'FooBar'
camelCase('foo-bar', {pascalCase: false});
//=> 'fooBar'Type: boolean
Default: false
Preserve consecutive uppercase characters: foo-BAR → FooBAR
import camelCase from 'camelcase';
camelCase('foo-BAR', {preserveConsecutiveUppercase: true});
//=> 'fooBAR'
camelCase('foo-BAR', {preserveConsecutiveUppercase: false});
//=> 'fooBar'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.
import camelCase from '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 algorithm:
import camelCase from 'camelcase';
// On a platform with `tr-TR`.
camelCase('lorem-ipsum');
//=> 'loremİpsum'
camelCase('lorem-ipsum', {locale: false});
//=> 'loremIpsum'- decamelize - The inverse of this module
