import { ucsplit } from "@tolki/str";

const result = ucsplit("FooBar");

// result is ["Foo", "Bar"]

ucwords

Uppercase the first letter of each word in a string.

import { ucwords } from "@tolki/str";

const result = ucwords("laravel framework");

// result is "Laravel Framework"

upper

Convert the given string to upper-case.

import { upper } from "@tolki/str";

const result = upper("laravel");

// result is "LARAVEL"

ulid

Generate a ULID (Universally Unique Lexicographically Sortable Identifier).

Uses the ulid package.

import { ulid } from "@tolki/str";

const result = ulid();

// result is "01F8MECHZX2D7J8F8C8D4B8F8C"

During testing, you can use the createUlidsUsing function to provide a custom ULID generator for predictable results.

import { createUlidsUsing, ulid } from "@tolki/str";

createUlidsUsing(() => "custom-ulid");

const result = ulid();

// result is "custom-ulid"

You can reset to the default ULID generator by calling the createUlidsNormally function.

import { createUlidsUsing, createUlidsNormally, ulid } from "@tolki/str";

createUlidsUsing(() => "custom-ulid");

const result = ulid();

// result is "custom-ulid"

createUlidsNormally();

const result2 = ulid();

// result is a randomly generated ULID

unwrap

Unwrap the string with the given strings.

import { unwrap } from "@tolki/str";

const result = unwrap("-Laravel-", "-");

// result is "Laravel"

const result2 = unwrap('{framework: "Laravel"}', "{", "}");

// result2 is 'framework: "Laravel"'

uuid

Generate a UUID (version 4).

Uses the uuid package.

import { uuid } from "@tolki/str";

const result = uuid();

// result is a randomly generated UUID (version 4)

During testing, you can use the createUuidsUsing function to provide a custom UUID generator for predictable results.

import { createUuidsUsing, uuid } from "@tolki/str";

createUuidsUsing(() => "custom-uuid");

const result = uuid();

// result is "custom-uuid"

You can reset to the default UUID generator by calling the createUuidsNormally function.

import { createUuidsUsing, createUuidsNormally, uuid } from "@tolki/str";

createUuidsUsing(() => "custom-uuid");

const result = uuid();

// result is "custom-uuid"

createUuidsNormally();

const result2 = uuid();

// result is a randomly generated UUID

uuid7

Generate a UUID (version 7).

Uses the uuid package.

import { uuid7 } from "@tolki/str";

const result = uuid7();

// result is a randomly generated UUID (version 7)

The uuid7() function also uses the createUuidsUsing and createUuidsNormally functions for testing purposes, as described in the uuid function above.

wordCount

Get the number of words a string contains.

import { wordCount } from "@tolki/str";

const result = wordCount("Hello, world!");

// result is 2

wordWrap

Wrap a string to a given number of characters.

import { wordWrap } from "@tolki/str";

const result = wordWrap(
  "The quick brown fox jumped over the lazy dog.",
  20,
  "<br />\n",
);

// result is:
/*
The quick brown fox<br />
jumped over the lazy<br />
dog.
*/

words

Limit the number of words in a string.

import { words } from "@tolki/str";

const result = words("Perfectly balanced, as all things should be.", 3, " >>>");

// result is "Perfectly balanced, as >>>"

wrap

Wrap the string with the given strings.

import { wrap } from "@tolki/str";

const result = wrap("Laravel", '"');

// result is '"Laravel"'

const result2 = wrap("is", "This ", " Laravel!");

// result2 is 'This is Laravel!'

str

WARNING

Using the str or of functions is discouraged for frontend projects because it will import the entire Stringable class, all of its methods, and all 3rd party dependencies into your final bundle, which may significantly increase its size.

For frontend projects, it is recommended to use the individual string functions instead for better tree-shaking and smaller bundle sizes.

Get a new Stringable object from the given string.

import { str } from "@tolki/str";

const result = str("Laravel").append(" Otwell");

// result is a Stringable class instance representing "Laravel Otwell"

If no string is provided, a Stringable class instance with an empty string will be returned.

import { str } from "@tolki/str";

const result = str().snake("FooBar");

// result is a Stringable class instance representing "foo_bar"

of

The of function is an alias for the str function made for parity with Laravels' Str::of method. See the str function documentation for details.

import { of } from "@tolki/str";

const result = of("Laravel").upper();

// result is a Stringable class instance representing "LARAVEL"
