Uses data from https://www.iso.org/iso-3166-country-codes.html

## Install

``` cli

```

```js
import React, { useState, useMemo } from 'react'
import Select from 'react-select'
import countryList from 'react-select-country-list'

function CountrySelector() {
  const [value, setValue] = useState('')
  const options = useMemo(() => countryList().getData(), [])

const changeHandler = value => {
    setValue(value)

## Methods

All input is case-insensitive.

### getValue(label)

Expects the English country name.
Returns the code for that country.
If not found, it returns `undefined`.

### getLabel(value)

Expects a two-digit country code.
Returns the name for that country.
If not found, it returns `undefined`.

### getValues()

Returns an array of all country codes.

### getLabels()

Returns an array of all country names.

### getValueList()

Returns a key-value object of all countries using the code as key.

### getLabelList()

Returns a key-value object of all countries using the name as key.

### getData()

Returns an array of all country information, in the same format as it gets imported.

### setLabel(value, label)

Due to different perspectives among different regions, this method can help developers customize the label of specific country. What's more, it can be chained with another methods above.

#### Usage
```js
// Make 'Viet Nam' -> 'Vietnam'
countries.setLabel('VN', 'Vietnam').getLabel('VN') // 'Vietnam'
```

### setEmpty(label)

You may want an empty value option in the list, so here's the helper function for you. Again, it can be chained with another methods above.

#### Usage
```js
countries.setEmpty('Select a Country').getLabel('') // 'Select a Country'
```

We can even chain `setLabel` and `setEmpty` together to have list with an empty option and the modified label.
```js
countries.setLabel('VN', 'Vietnam').setEmpty('Select a Country').getLabel('VN') // 'Vietnam'
```

### native()

You may want to display native name of countries, this is the method for you.
The data source of native names can be found [here](https://annexare.github.io/Countries/)

#### Usage
```js
countries.native().getLabel('TW') // 臺灣
```
