  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,

} 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
};
