## Installation and Usage

#### Using npm

```bash
npm install mozambique-utils
```

```javascript
const mozambiqueUtils = require("mozambique-utils"); // -> No ES6
// import mozambiqueUtils from "mozambique-utils";   // -> or with ES6

mozambiqueUtils.isNUITValid("300010125"); //-> true
```

#### In a browser

This library can be loaded as a standalone script, which will then be made available through the `mozambiqueUtils` global object.

```html
<script src="https://unpkg.com/mozambique-utils@1.1.1/dist/mozambique-utils.js"></script>

## API

### `isLandlineNumberValid(number [, options])`

Check if a string is a valid mozambican landline number.
Returns `true` if valid, otherwise `false`.

###### number

The number to check. Must be of type string and can contain dashes or spaces.\
Will throw if not of type string.

###### options

An object that defaults to:

```javascript
{
    allowedRegions: [],
    countryCode: "optional"
}
```

| Option         | Type     | Accepted value(s)                                                                                                                 | Description                                                                                                                                                                                                                                                                                            |

## Contributing

##### Bug Reports & Feature Requests

Please use the issue tracker to report any bugs or file feature requests.

##### Developing

PRs are welcome. To begin developing, do this:

```bash
$ git clone https://github.com/kishannareshpal/mozambique-utils.js.git
$ cd mozambique-utils/
$ npm install

# Test
$ npm test
```

`npm run build` builds the library to dist, generating three main files (and also a minified version for each one with the `*.min.js` prepended):

-   `dist/mozambique-utils.cjs.js` A CommonJS bundle, suitable for use in Node.js, that requires the external dependency. This corresponds to the "main" field in package.json
-   `dist/mozambique-utils.esm.js` an ES module bundle, suitable for use in other people's libraries and applications, that imports the external dependency. This corresponds to the "module" field in package.json
-   `dist/mozambique-utils.js` a UMD build, suitable for use in any environment (including the browser, as a `<script>` tag), that includes the external dependency. This corresponds to the `"browser"` field in package.json

`npm run dev` builds the library, then keeps rebuilding it whenever the source files change using [`rollup.watch`](https://rollupjs.org/guide/en/#rollupwatch).

`npm test` builds the library, then tests it.
