Getting Started

Installation

npm

npm install 1o1-utils

pnpm

pnpm add 1o1-utils

yarn

yarn add 1o1-utils

bun

bun add 1o1-utils

Import

Full library

import { chunk, pick, slugify, retry } from "1o1-utils";

Individual modules

For the smallest possible bundle, import only the utilities you need:

import { chunk } from "1o1-utils/chunk";
import { pick } from "1o1-utils/pick";
import { slugify } from "1o1-utils/slugify";
import { retry } from "1o1-utils/retry";

Each individual module is under 2 kB gzipped.

Requirements

• Node.js >= 20
• ESM only — this package uses "type": "module"

Quick example

import { chunk, sortBy, unique } from "1o1-utils";

const users = [
  { name: "Alice", age: 30 },
  { name: "Bob", age: 25 },
  { name: "Alice", age: 30 },
];

const deduplicated = unique({ array: users, key: "name" });
// => [{ name: "Alice", age: 30 }, { name: "Bob", age: 25 }]

const sorted = sortBy({ array: deduplicated, key: "age" });
// => [{ name: "Bob", age: 25 }, { name: "Alice", age: 30 }]

const batches = chunk({ array: sorted, size: 1 });
// => [[{ name: "Bob", age: 25 }], [{ name: "Alice", age: 30 }]]
