picklyfy

Tiny TypeScript utility to pick or omit keys from objects, with optional deep (dot-path) support.

Install

npm install picklyfy
# or
yarn add picklyfy

Usage

import picklyfy, { pick, omit } from "picklyfy";

const data = {
  id: 1,
  user: { name: "Vinod", email: "[email protected]" },
  meta: { tags: ["js", "ts"] }
};

// pick shallow keys
const a = pick(data, ["id"]);
// => { id: 1 }

// pick deep path
const b = pick(data, ["user.name", "meta.tags"], { deep: true });
// => { user: { name: 'Vinod' }, meta: { tags: ['js','ts'] } }

// omit shallow
const c = omit(data, ["meta"]);
// => { id:1, user: { name: 'Vinod', email: '[email protected]' } }

// convenience
const d = picklyfy(data, ["user.name"], { deep: true, mode: "pick" });

API

• pick(obj, keys, { deep?: boolean }) - returns object with only selected keys
• omit(obj, keys, { deep?: boolean }) - returns object without selected keys
• picklyfy(obj, keys, { deep?: boolean, mode?: "pick" | "omit" }) - wrapper
