RECASE

Change and detect the casing of a string.

Install

npm i @kristiandupont/recase

Use

const { recase, detectCasing } = require("@kristiandupont/recase");

const initialCase = "snake";

const toCamel = recase(initialCase, "camel");
const toDash = recase(initialCase, "dash");

const s = "some_string_initially_set_with_snake_case";

console.log("Camel cased version:", toCamel(s));
// prints: "Camel cased version: someStringInitiallySetWithSnakeCase"

console.log("Dash cased version:", toDash(s));
// prints: "Dash cased version: some-string-initially-set-with-snake-case"

console.log("Casing detected:", detectCasing(s));
// prints: "Casing detected: snake"

recase

recase(from, to, str);

Takes two casing parameters which can both be one of dash, snake, camel or pascal. Additionally, from can be mixed or null which will make all word boundaries considered. The third parameter is the string to recase. This function is curried which means that if you call it with fewer than three parameters, the return value will be a new function, with the initial parameters bound. So if you want to have a function that converts any string to a pascal-cased one, you can create it like so:

const toPascal = recase(null, "pascal");

console.log(toPascal("snake_case"));
// Prints: "SnakeCase"

detectCasing

detectCasing(str);

Takes a string that has been formatted. It will attempt to detect the casing.

Casings

• screamingDash: EXAMPLE-STRING
• snake: example_string
• screamingSnake: EXAMPLE_STRING
• camel: exampleString
• pascal: ExampleString
• prose: example string
