# MR PORTER URL Generator ![Build status](https://circleci.com/gh/NET-A-PORTER/mrp-url-generator.png?circle-token=:circle-token)

An isomorphic JavaScript library to generate URLs used across the MR PORTER sites, following our agreed formatting conventions.

## Usage
```
npm i mrp-url-generator --save
```

### ECMAScript 6
```
import { buildProductDetailsUrl } from 'mrp-url-generator';

/* alternatively, one can import the entire library with:
 * import urlGen from 'mrp-url-generator'; */
```

### ECMAScript 5
```
var buildProductDetailsUrl = require('mrp-url-generator').buildProductDetailsUrl;
```

### Browser
This is confirmed to work with Browserify and Webpack.

If, unfortunately, `script` tag includes are the only option, one must build the distributable manually with a tool such as Browserify:
```
browserify dist/index.js --outfile mrp-url-generator.js
```

## API

All methods return `String`s representing relative URLs

### `buildProductDetailsUrl(brandUrlKey, productName, productId, locale)`
Returns a product details page link e.g:

```
//returns '/en-gb/mens/mario_super_designer/my-3456-woouuuuderful-trou-ers-are-great/12345'
buildProductDetailsUrl('Mario_Super_Designer', 'My 3456 Ẅöőuúüűderful Trou$ers! Are great', 12345, 'en-gb');
```

## Contributing
### Setup

```
npm i -g babel
npm i
```

### Babel?! Why does this project use ECMAScript 6?

1. Harmony has a lot of useful enhancements, especially to `String.prototype`
2. Once io.js has fully merged with Node.js, everything should just work!
3. Native Harmony support is gradually improving

### Tasks

* `npm run dist` - compiles the distributable to ECMAScript 5
* `npm test` - runs unit tests
