# 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
