### Module Import Examples

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Demonstrates how to import the package in both CommonJS and ES Modules environments. Both methods are supported.

```javascript
// CommonJS (still works)
const countryCodes = require("country-codes-list");

// ES Modules (new)
import * as countryCodes from "country-codes-list";
```

--------------------------------

### Install country-codes-list via npm

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Install the package using npm. This command adds the package as a dependency to your project.

```bash
npm install --save country-codes-list
```

--------------------------------

### TypeScript Usage Example

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Example of using the `customList` method in a TypeScript environment to generate a custom object of country codes.

```typescript
import * as countryCodes from "country-codes-list";

const myCountryCodesObject = countryCodes.customList(
  "countryCode",
  "[{countryCode}] {countryNameEn}: +{countryCallingCode}"
);
console.log(myCountryCodesObject);
```

--------------------------------

### customList Method Example

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Demonstrates the usage of the `customList` method, which creates a custom object by mapping country properties to a specified string format.

```javascript
const countryCodes = require("country-codes-list");

const myCountryCodesObject = countryCodes.customList(
  "countryCode",
  "[{countryCode}] {countryNameEn}: +{countryCallingCode}"
);
```

--------------------------------

### customList Method Output Example

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

An example of the output generated by the `customList` method, showing a JavaScript object where keys are country codes and values are formatted strings.

```javascript
{
    'AD': '[AD] Andorra: +376',
    'AE': '[AE] United Arab Emirates: +971',
    'AF': '[AF] Afghanistan: +93',
    'AG': '[AG] Antigua and Barbuda: +1',
    'AI': '[AI] Anguilla: +1',
    'AL': '[AL] Albania: +355',
    'AM': '[AM] Armenia: +374',
    'AO': '[AO] Angola: +244',
    'AQ': '[AQ] Antarctica: +',
    'AR': '[AR] Argentina: +54',
    'AS': '[AS] American Samoa: +1',
    'AT': '[AT] Austria: +43',
    'AU': '[AU] Australia: +61',
    'AW': '[AW] Aruba: +297',
    ...
}
```

--------------------------------

### CommonJS Usage Example

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Example of using the `customList` method in a CommonJS environment to generate a custom object of country codes.

```javascript
const countryCodes = require("country-codes-list");

const myCountryCodesObject = countryCodes.customList(
  "countryCode",
  "[{countryCode}] {countryNameEn}: +{countryCallingCode}"
);

console.log(myCountryCodesObject);
```

--------------------------------

### Stricter Type Checking Example

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Shows how function calls now require valid country property keys. Passing an invalid key will result in a TypeScript error.

```typescript
// This now requires valid country property keys
countryCodes.filter("invalidKey", "value"); // TypeScript error
```

--------------------------------

### TypeScript Type Migration Example

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Illustrates the change in importing TypeScript types from v1.x to v2.0. In v2.0, types are imported directly, and properties are accessed as string literals.

```typescript
// Old (v1.x)
import { CountryProperty } from "country-codes-list";
const prop: CountryProperty = CountryProperty.countryCode;

// New (v2.0)
import type { CountryProperty } from "country-codes-list";
const prop: CountryProperty = "countryCode";
```

--------------------------------

### Build the package

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Compile the package source code. The output will be placed in the 'dist/' folder.

```bash
npm run build
```

--------------------------------

### Run tests for the package

Source: https://github.com/synergy-shock/country-codes-list/blob/master/README.md

Execute the test suite to ensure the package is functioning correctly.

```bash
npm test
```
