Pickrr


Contracts in Typescript done right.

Goal

To have a simple contract in typescript that doesn't need an accompanying interface.
i.e. The contract itself is the interface.

Installation

``bash
npm i --save pickrr
`

Usage

`ts
import {pick, number, string} from 'pickrr'

// Let's say req.body = {id: '1', name: 'John Doe'}

const data = pick({
id: number,
name: string,
}, req.body);

// data now has a signature of {id: number; name: string}
// and a value of {id: 1, name: 'John Doe'}
`

You can even pass multiple objects
`ts
import {pick, number, string, date} from 'pickrr'

const data = pick({
id: number,
name: string,
birthdate: date,
}, req.params, req.body);

// data now has the same signature as the contract itself.
`

The trick?
Take a look at src/index.ts`.
