Library with various utilities for userscripts - register listeners for when CSS selectors exist, intercept events, create persistent & synchronous data stores, modify the DOM more easily and more.
Contains builtin TypeScript declarations. Fully web compatible and supports ESM and CJS imports and global declaration.

You may want to check out my template for userscripts in TypeScript that you can use to get started quickly. It also includes this library by default.
If you like using this library, please consider supporting the development ❤️

npm i @sv443-network/userutils
Then, import it in your script as usual:
import { addGlobalStyle } from "@sv443-network/userutils";
// or just import everything (not recommended because of worse treeshaking support):
import * as UserUtils from "@sv443-network/userutils";
Shameless plug: I made a webpack-based template for userscripts in TypeScript that you can use to get started quickly. It also includes this library by default.
If you are not using a bundler, you can include the latest release by adding one of these directives to the userscript header, depending on your preferred CDN:
// @require https://greasyfork.org/scripts/472956-userutils/code/UserUtils.js
// @require https://openuserjs.org/src/libs/Sv443/UserUtils.js
(in order for your userscript not to break on a major library update, use the versioned URL at the top of the GreasyFork page)
Then, access the functions on the global variable UserUtils:
UserUtils.addGlobalStyle("body { background-color: red; }");
// or using object destructuring:
const { clamp } = UserUtils;
console.log(clamp(1, 5, 10)); // 5
