Format Date

The FormatDate component returns a time tag with formatted date.
The date prop must be a string that Date.parse() can interpret or a Date object.

If locale is not passed, navigator.language is used or, if it is not specified, the 'en-US' locale is used.

import React from 'react';
import { FormatDate } from 'react-format-kit';

const App = () => (
  <div>
    {/* Human-readable format: current date with current locale */}
    <FormatDate format="human" />

    {/* Numeric format: will render 10/09/1991 */}
    <FormatDate date="1991-10-09T10:00:00Z" format="numeric" locale="en-US" />

    {/* ISO format: will render "1991-10-09T10:00:00.000Z" */}
    <FormatDate date="1991-10-09T10:00:00Z" format="iso" />

Format Number

The FormatNumber component returns a span tag with formatted number.

const App = () => (
  <div>
    {/* Will render 10,000 */}

    {/* Will render 10.000 */}
    <FormatNumber value={10000} locale='it-IT' />

    {/* Will render 10.000,98 */}
    <FormatNumber value={10000.98} minimumFractionDigits={1} maximumFractionDigits={2} locale='it-IT' />

Format Currency

The FormatCurrency component returns a span tag with formatted number.
The currency will be to default USD if not specified. Must be a valid currency in ISO 4217 list.
