What is change-case?

The change-case package is a utility library that provides various functions to transform strings between different cases, such as camel case, snake case, kebab case, and more. It is useful for formatting strings in different coding conventions or textual formats.

What are change-case's main functionalities?

camelCase

Converts a string to camel case.

const { camelCase } = require('change-case');
console.log(camelCase('test string')); // 'testString'

snakeCase

Converts a string to snake case.

const { snakeCase } = require('change-case');
console.log(snakeCase('test string')); // 'test_string'

kebabCase

Converts a string to kebab case.

const { kebabCase } = require('change-case');
console.log(kebabCase('test string')); // 'test-string'

titleCase

Converts a string to title case.

const { titleCase } = require('change-case');
console.log(titleCase('test string')); // 'Test String'

constantCase

Converts a string to constant case.

const { constantCase } = require('change-case');
console.log(constantCase('test string')); // 'TEST_STRING'

Other packages similar to change-case

lodash

Lodash is a comprehensive utility library that includes methods for string case transformation, such as _.camelCase, _.snakeCase, and _.kebabCase. It offers a wider range of utilities beyond string case conversion, making it more versatile but also larger in size compared to change-case.

case

The 'case' package is another string case conversion library that supports various case transformations. It is similar to change-case but has a different API and may have different case conversion implementations.

string-case

String-case is a library that provides case conversion functions similar to change-case. It may offer a different set of features or API design, which could be preferred by some developers over change-case.

Installation

API

var changeCase = require('change-case');

upperCase changeCase.upperCase(string)

Upper cases a string.

changeCase.upperCase('test string');
--> "TEST STRING"

lowerCase changeCase.lowerCase(string)

Lower cases a string.

changeCase.lowerCase('TEST STRING');
--> "test string"

upperCaseFirst changeCase.upperCaseFirst(string)

Upper cases only the first character of a string.

changeCase.upperCaseFirst('test string');
--> "Test string"

lowerCaseFirst changeCase.lowerCaseFirst(string)

Lower cases only the first character of a string.

changeCase.lowerCaseFirst('TEST STRING');
--> "tEST STRING"

titleCase changeCase.titleCase(string)

Title cases a string, useful for user inputted values being shown as titles. It does minimal sanitization of characters and will not handle non-sentence formats correctly (since it risks breaking formatting). If you need to parse a string in a different format, pass it through sentenceCase first.

changeCase.titleCase('a simple test');
--> "A Simple Test"

sentenceCase changeCase.sentenceCase(string)

Transforms a string from any format to a lower cased sentence.

changeCase.sentenceCase('testString');
--> "test string"

camelCase changeCase.camelCase(string)

Converts a string to a camel cased word.

changeCase.camelCase('test string');
--> "testString"

snakeCase changeCase.snakeCase(string)

Converts a string to an underscore separated string.

changeCase.snakeCase('test string');
--> "test_string"

paramCase changeCase.paramCase(string)

Converts a string to a dash separated string.

changeCase.paramCase('test string');
--> "test-case"

dotCase changeCase.dotCase(string)

Converts a string to a period separated string.

changeCase.dotCase('test string');
--> "test.string"

pathCase changeCase.pathCase(string)

Converts a string to a slash separated string.

changeCase.pathCase('test string');
--> "test/string"

constantCase changeCase.constantCase(string)

Converts a string to a constant styled string (upper case separated by underscores).

changeCase.constantCase('test string');
--> "TEST_STRING"
