# table-to-record

Typescript package to convert a table (rectangular array) to a well-typed record (aka object/map/dictionary) so you can concisely store data. (Instead of repeating yourself a million times in an enourmous json.)

```sh

npm i table-to-record

```

Usage: `tableToRecord(rows, header, indexToKeyBy)`

## Example

```ts

import { tableToRecord } from 'table-to-record'

const header = ['uid', 'price', 'name', 'is_available'] as const

const rows = [

    [888, 2, 'bread', false],

    [999, 5, 'milk', true],

] as const

const rec = tableToRecord(rows, header, '0')

// has exact types!

const breadAvailable: true = rec[999].is_available

const _t: false = rec[888].is_available

console.log(rec)

/* Result:

{

    '888': { uid: 888, price: 2, name: '3', is_available: false },

    '999': { uid: 999, price: 5, name: '6', is_available: true },

}

*/

```
