Object Reshaper

TypeScript-first schema-based object transformation.

Installation

Requirements

• TypeScript 4.9+

$ npm install object-reshaper

Basic Usage

Renaming property names

import { reshaperBuilder, Schema } from "object-reshaper";

type Input = {
  id: number;
};
const schema = {
  new: "id",
} as const satisfies Schema<Input>;
const reshaper = reshaperBuilder<Input, typeof schema>(schema);
reshaper({ id: 1 }); // => { new: 1 } (Type: { new: number })

Extracting nested properties

import { reshaperBuilder, Schema } from "object-reshaper";

type Input = {
  user: {
    address: {
      street: string;
    };
  };
};
const schema = {
  street: "user.address.street",
} as const satisfies Schema<Input>;
const reshaper = reshaperBuilder<Input, typeof schema>(schema);
reshaper({ user: { address: { street: "home" } } }); // => { new: "home" } (Type: { new: string })
