Camel case

Convert a dash/dot/underscore/space separated string to camelCase or PascalCase.

Correctly handles unicode strings.

If you use this on untrusted user input, don't forget to limit the length to something reasonable.

Based on the Sindre Sorhus Camelcase Module, they have the same test suite and API, but this version is more than 3 times faster, see the benchmarks below!

Usage

The API is the same on all this platforms ✔️

Deno 🦕

import { camelcase } from "https://deno.land/x/camelcase/mod.ts";

camelCase("foo-bar"); //=> 'fooBar'

camelCase("foo_bar"); //=> 'fooBar'

camelCase("Foo-Bar"); //=> 'fooBar'

camelCase("розовый_пушистый_единорог"); //=> 'розовыйПушистыйЕдинорог'

camelCase("Foo-Bar", { pascalCase: true }); //=> 'FooBar'

camelCase("--foo.bar", { pascalCase: false }); //=> 'fooBar'

camelCase("Foo-BAR", { preserveConsecutiveUppercase: true }); //=> 'fooBAR'

camelCase("fooBAR", { pascalCase: true, preserveConsecutiveUppercase: true }); //=> 'FooBAR'

camelCase("foo bar"); //=> 'fooBar'

camelCase(["foo", "bar"]); //=> 'fooBar'

camelCase(["__foo__", "--bar"], { pascalCase: true }); //=> 'FooBar'

camelCase(["foo", "BAR"], {
  pascalCase: true,
  preserveConsecutiveUppercase: true,
}); //=> 'FooBAR'

camelCase("lorem-ipsum", { locale: "en-US" }); //=> 'loremIpsum'
