import {

  pascalCase, // `PascalCase`
  capitalCase, // `Capital Case`
  headerCase, // `Header-Case`
  titleCase, // `Title Case`
  pathCase, // `path/case`
  snakeCase, // `snake_case`
  paramCase, // `param-case`
  dotCase, // `dot.case`
  noCase, // `no case`
  constantCase, // `CONSTANT_CASE`
  lowerCase, // `lower case`
  lowerCaseFirst, // `lOWER CASE FIRST`
  upperCase, // `UPPER CASE`
  upperCaseFirst, // `Upper case first`
  swapCase, // `sWaP cAsE` -> `SwAp CaSe`
  sentenceCase,
  isLowerCase,
  isUpperCase
} from "text-case";

Methods can also be installed independently. All functions also accept options as the second argument.

Options

• splitRegexp RegExp used to split into word segments (see example).
• stripRegexp RegExp used to remove extraneous characters (default: /[^A-Z0-9]/gi).
• delimiter Value used between words (e.g. " ").
• transform Used to transform each word segment (e.g. lowerCase).

Split Example

If you find the default split hard to use, you can provide a different one. The example below will change the behavior to expo2020 -> expo 2020 and WorldExpo -> world expo:

const options = {
  splitRegexp: /([a-z])([A-Z0-9])/g
};
