Change Case

Transform a string between camelCase, PascalCase, Capital Case, snake_case, kebab-case, CONSTANT_CASE and others.

Installation

npm install change-case --save

Usage

1import * as changeCase from "change-case";
2
3changeCase.camelCase("TEST_VALUE"); //=> "testValue"

Included case functions:

Method	Result
`camelCase`	`twoWords`
`capitalCase`	`Two Words`
`constantCase`	`TWO_WORDS`
`dotCase`	`two.words`
`kebabCase`	`two-words`
`noCase`	`two words`
`pascalCase`	`TwoWords`
`pascalSnakeCase`	`Two_Words`
`pathCase`	`two/words`
`sentenceCase`	`Two words`
`snakeCase`	`two_words`
`trainCase`	`Two-Words`

All methods accept an options object as the second argument:

delimiter?: string The character to use between words. Default depends on method, e.g. _ in snake case.
locale?: string[] | string | false Lower/upper according to specified locale, defaults to host environment. Set to false to disable.
split?: (value: string) => string[] A function to define how the input is split into words. Defaults to split.
prefixCharacters?: string Retain at the beginning of the string. Defaults to "". Example: use "_" to keep the underscores in __typename.
suffixCharacters?: string Retain at the end of the string. Defaults to "". Example: use "_" to keep the underscore in type_.

By default, pascalCase and snakeCase separate ambiguous characters with _. For example, V1.2 would become V1_2 instead of V12. If you prefer them merged you can set mergeAmbiguousCharacters to true.

Split

Change case exports a split utility which can be used to build other case functions. It accepts a string and returns each "word" as an array. For example:

1split("fooBar")
2  .map((x) => x.toLowerCase())
3  .join("_"); //=> "foo_bar"

Change Case Keys

1import * as changeKeys from "change-case/keys";
2
3changeKeys.camelCase({ TEST_KEY: true }); //=> { testKey: true }

Change case keys wraps around the core methods to transform object keys to any case.

API

input: any Any JavaScript value.
depth: number Specify the depth to transfer for case transformation. Defaults to 1.
options: object Same as base case library.

TypeScript and ESM

This package is a pure ESM package and ships with TypeScript definitions. It cannot be require'd or used with CommonJS module resolution in TypeScript.
