# A Node.js library for accessing country, state, and city data

This library provides functions to retrieve information about countries, states, and cities from a provided JSON data file. It allows you to search for specific data points, including phone codes and currency symbols.

```
npm install js-locations
```

## Usage

1. Import the Library

```javascript
import countries from "js-locations";
```

2. Access Data:

The library provides a single function getCountryData to retrieve information based on different parameters.

- `getCountryData(option)`: This function takes an options object as a parameter and returns an array of matching entries.

Available options for searching:

- `country`: Search by country name (string).
- `state`: Search by state name (string).
- `city`: Search by city name (string).
- `phone_code`: Search by phone code (string).
- `currency_symbol`: Search by currency symbol (string).

Examples

- Get all countries:

```JavaScript
const allCountries = countries.getCountryData();
console.log(allCountries);
```

- Get a specific country by name:

```JavaScript
const usaData = countries.getCountryData({ country: 'United States' });
console.log(usaData);
```

- Find cities within a state:

```JavaScript
const californiaCities = countries.getCountryData({ state: 'California' });
console.log(californiaCities.map(city => city.city)); // Extract city names
```
