# slugify
[![npm-version]][npm] [![coveralls-status]][coveralls]
```js
var slugify = require('slugify')
slugify('some string') // some-string
// if you prefer something other than '-' as separator
slugify('some string', '_') // some_string
```
- Vanilla ES2015 JavaScript
- If you need to use Slugify with older browsers, consider using [version 1.4.7](https://github.com/simov/slugify/releases/tag/v1.4.7)
- No dependencies
- Coerces foreign symbols to their English equivalent (check out the [charMap][charmap] for more details)
- Works in the browser (window.slugify) and AMD/CommonJS-flavored module loaders
## Options
```js
slugify('some string', {
replacement: '-', // replace spaces with replacement character, defaults to `-`
remove: undefined, // remove characters that match regex, defaults to `undefined`
lower: false, // convert to lower case, defaults to `false`
strict: false, // strip special characters except replacement, defaults to `false`
locale: 'vi', // language code of the locale to use
trim: true // trim leading and trailing replacement chars, defaults to `true`
})
```
## Remove
For example, to remove `*+~.()'"!:@` from the result slug, you can use `slugify('..', {remove: /[*+~.()'"!:@]/g})`.
* If the value of `remove` is a regular expression, it should be a
[character class](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions/Character_Classes)
and only a character class. It should also use the
[global flag](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/global).
(For example: `/[*+~.()'"!:@]/g`.) Otherwise, the `remove` option might not
work as expected.
* If the value of `remove` is a string, it should be a single character.
Otherwise, the `remove` option might not work as expected.
## Locales
The main `charmap.json` file contains all known characters and their transliteration. All new characters should be added there first. In case you stumble upon a character already set in `charmap.json`, but not transliterated correctly according to your language, then you have to add those characters in `locales.json` to override the already existing transliteration in `charmap.json`, but for your locale only.
You can get the correct language code of your language from [here](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes).
## Extend
Out of the box `slugify` comes with support for a handful of Unicode symbols. For example the `☢` (radioactive) symbol is not defined in the [`charMap`][charmap] and therefore it will be stripped by default:
```js
slugify('unicode ♥ is ☢') // unicode-love-is
```
However you can extend the supported symbols, or override the existing ones with your own:
```js
slugify.extend({'☢': 'radioactive'})
slugify('unicode ♥ is ☢') // unicode-love-is-radioactive
```
Keep in mind that the `extend` method extends/overrides the default `charMap` for the entire process. In case you need a fresh instance of the slugify's `charMap` object you have to clean up the module cache first:
```js
delete require.cache[require.resolve('slugify')]
var slugify = require('slugify')
```
## Contribute
1. Add chars to `charmap.json`
2. Run tests `npm test`
3. The tests will build the charmap in `index.js` and will sort the `charmap.json`
4. Commit **all** modified files
