Javascript Slugify

slugify.js

function slugify(text)
{
  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '');            // Trim - from end of text
}

Neat! Thanks for sharing

Yeh, thanks for sharing 👍

Thanks to google search, github, and you to make my job easy every now and then

Great snippet! Saved me a lot of time.

thx!

Trim is much simpler than 2 regex replaces! Just do:

string.trim();

And your code works only for English!

Thanks is useful, but can you give some link where I can find documentation

Thanks!!!

This is Awesome!!

👍

Thank you!

Cool. Here is a popular alternative for people that stumble across this page first.

Thanks

I've completed a little:

• with .trim() (thx. @alexbruno)
• replace '&' to 'and'

My final version is:

return text.toString().toLowerCase().trim()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(/&/g, '-and-')         // Replace & with 'and'
    .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
    .replace(/\-\-+/g, '-');        // Replace multiple - with single -

Ex. " IT&Computer " => "it-and-computer"

Just what I looked for! Many thanks!

You can make it a lot shorter:

return text.toString().toLowerCase().trim()
    .replace(/&/g, '-and-')         // Replace & with 'and'
    .replace(/[\s\W-]+/g, '-')      // Replace spaces, non-word characters and dashes with a single dash (-)

add

.replace(/-$/, '') // Remove last floating dash if exists

otherwise text containing smily faces at the end of them have floating dashes

thank u

return string.toLowerCase()
  .replace(/[^\w\s-]/g, '') // remove non-word [a-z0-9_], non-whitespace, non-hyphen characters
  .replace(/[\s_-]+/g, '-') // swap any length of whitespace, underscore, hyphen characters with a single -
  .replace(/^-+|-+$/g, ''); // remove leading, trailing -

❤️

TY

I am using this, for change special char, Ex: Marcos Fábio > marcos-fabio

  str = str.replace(/^\s+|\s+$/g, ''); // trim
  str = str.toLowerCase();

  // remove accents, swap ñ for n, etc
  var from = "àáäâèéëêìíïîòóöôùúüûñç·/_,:;";
  var to   = "aaaaeeeeiiiioooouuuunc------";

  for (var i=0, l=from.length ; i<l ; i++)
    str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));


  str = str.replace(/[^a-z0-9 -]/g, '') // remove invalid chars
    .replace(/\s+/g, '-') // collapse whitespace and replace by -
    .replace(/-+/g, '-'); // collapse dashes

  return str;

Noooooish!

Thanks @stevemoser https://github.com/dodo/node-slug works great even in my Meteor app with the 'rfc3986' default

thanks

Thanks

thanx (:

Thanks ! :)

Thank you for this.
I created a snippet Auto Slugify: https://jsfiddle.net/agaust/xht31h97/2/

Thanks!

Thanks for this! Super useful! :)

ES6 version with special chars replacement.

function slugify (text) {
  const a = 'àáäâèéëêìíïîòóöôùúüûñçßÿœæŕśńṕẃǵǹḿǘẍźḧ·/_,:;'
  const b = 'aaaaeeeeiiiioooouuuuncsyoarsnpwgnmuxzh------'
  const p = new RegExp(a.split('').join('|'), 'g')

  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(p, c =>
        b.charAt(a.indexOf(c)))     // Replace special chars
    .replace(/&/g, '-and-')         // Replace & with 'and'
    .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '')             // Trim - from end of text
}

@joseluisq missing ã. thanks for the contribution

Thank you so much for this little snippet, does a lot of work and saved a lot of time doing it by myself. Thanks once again.

I have visit this page many times LOL . Thank you

Thank you Man !!

Great! Simple and sweet. I am using Django and needed something corresponding to Django's slugify (https://docs.djangoproject.com/en/1.11/_modules/django/utils/text/) in javascript and this looks good! Sweet, simple, needs no libraries or licenses.

And with the polish letters:

function slugify (str) {
  const from  = "ąàáäâãåæćęęèéëêìíïîłńòóöôõøśùúüûñçżź",
      to    = "aaaaaaaaceeeeeeiiiilnoooooosuuuunczz",
      regex = new RegExp('[' + from.replace(/([.*+?^=!:${}()|[\]\/\\])/g, '\\$1') + ']', 'g');

  if (str === null) return '';

  str = String(str).toLowerCase().replace(regex, function(c) {
    return to.charAt(from.indexOf(c)) || '-';
  });

  return str.replace(/[^\w\s-]/g, '').replace(/([A-Z])/g, '-$1').replace(/[-_\s]+/g, '-').toLowerCase();
};

Thanks

similar solution with more letters: https://stackoverflow.com/a/5782563/4939326

Awesome, but accent removal I think it's a must, I've made one, with a one-liner accent removal, that's not using some predefined chars.

Check it out - https://gist.github.com/eek/9c4887e80b3ede05c0e39fee4dce3747

Thank You

Thx!

// if you are lazy just... add more letter and their replacements and get rid of duplicates

}

import slugify from './slugify'

const slug = slugify('Great snippet! Saved me a lot of time.') // great-snippet-saved-me-a-lot-of-time

Here's my rendition of @kganser code, stripping out any non (a-z) characters or 0-9, trimming whitespace, and replacing with underscore _

function slugify(text){

  return text.toString().toLowerCase().trim()
    .replace(/[^\w\s-]/g, '') // remove non-word [a-z0-9_], non-whitespace, non-hyphen characters
    .replace(/[\s_-]+/g, '_') // swap any length of whitespace, underscore, hyphen characters with a single _
    .replace(/^-+|-+$/g, ''); // remove leading, trailing -

}

... yeah i basically just added .trim() ... but figured I would post it, and say thank you to everyone who came before me 😛

Thanks.

Not working for Turkish language. (ö ğ ş ü characters)

Don't do & => -and- the purpose of friendly URLs is not for users but rather search engines. And the and word doesn't add value at all (which is why most back-end systems also remove other pronouns and prepositions from it)

Thanks! 🤓

Awesome thread, thank you. Added in norwegian letters:

   slugify (text) {
    const a = 'æøåàáäâèéëêìíïîòóöôùúüûñçßÿœæŕśńṕẃǵǹḿǘẍźḧ·/_,:;';

      .replace(/\s+/g, '-')           // Replace spaces with -
      .replace(p, c =>

awesome. ty!

thanks, same me a lot of time!!!

For a better performance:

const slugify = text => {
  // Use hash map for special characters 
  let specialChars = {"à":'a',"ä":'a',"á":'a',"â":'a',"æ":'a',"å":'a',"ë":'e',"è":'e',"é":'e', "ê":'e',"î":'i',"ï":'i',"ì":'i',"í":'i',"ò":'o',"ó":'o',"ö":'o',"ô":'o',"ø":'o',"ù":'o',"ú":'u',"ü":'u',"û":'u',"ñ":'n',"ç":'c',"ß":'s',"ÿ":'y',"œ":'o',"ŕ":'r',"ś":'s',"ń":'n',"ṕ":'p',"ẃ":'w',"ǵ":'g',"ǹ":'n',"ḿ":'m',"ǘ":'u',"ẍ":'x',"ź":'z',"ḧ":'h',"·":'-',"/":'-',"_":'-',",":'-',":":'-',";":'-'};

    return text.toString().toLowerCase()
      .replace(/\s+/g, '-')           // Replace spaces with -
      .replace(/./g,(target, index, str) => specialChars[target] || target) // Replace special characters using the hash map
      .replace(/&/g, '-and-')         // Replace & with 'and'
      .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
      .replace(/\-\-+/g, '-')         // Replace multiple - with single -
      .replace(/^-+/, '')             // Trim - from start of text
      .replace(/-+$/, '');             // Trim - from end of text
};

Great! thanks (y)

Nice!

Thanks @mathewbyrne!
And if it's useful to someone, the code...

String.prototype.removeAcento = function () {       
    var text = this.toLowerCase();                                                         
    text = text.replace(new RegExp('[ÁÀÂÃ]','gi'), 'a');
    text = text.replace(new RegExp('[ÉÈÊ]','gi'), 'e');
    text = text.replace(new RegExp('[ÍÌÎ]','gi'), 'i');
    text = text.replace(new RegExp('[ÓÒÔÕ]','gi'), 'o');
    text = text.replace(new RegExp('[ÚÙÛ]','gi'), 'u');
    text = text.replace(new RegExp('[Ç]','gi'), 'c');
    return text;                 
};

String.prototype.slugify = function () {
    return this.toString().toLowerCase().removeAcento().trim()
      .replace(/\s+/g, '-')           // Replace spaces with -
      .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
      .replace(/\-\-+/g, '-')         // Replace multiple - with single -
      .replace(/^-+/, '')             // Trim - from start of text
      .replace(/-+$/, '');            // Trim - from end of text
}

I like the grouping of @philippeoz. With the use of this wikipedia page (https://en.wikipedia.org/wiki/Wikipedia:Language_recognition_chart) I collected all characters that resonate to latin characters. Here is my function:

Continue with @wearecharette version, added a separator option if you want to use different slug separators.

slugify(text, separator) {
    text = text.toString().toLowerCase().trim();

    const sets = [
        {to: 'a', from: '[ÀÁÂÃÄÅÆĀĂĄẠẢẤẦẨẪẬẮẰẲẴẶ]'},

it works! ;)

Wow everyone! what a great job making a great slugify function. Thanks!

❤️

Awesome thread folks!

Great job saved me a lot of time ! Thanks everyone :)

superb

Thank you for these suggestions!

I personally prefer to replace æ and Æ by ae instead of a.

You can do this by replacing:

    {to: 'a', from: '[ÀÁÂÃÄÅÆĀĂĄẠẢẤẦẨẪẬẮẰẲẴẶ]'},

with:

    {to: 'a', from: '[ÀÁÂÃÄÅĀĂĄẠẢẤẦẨẪẬẮẰẲẴẶ]'}, // note the Æ removing
    {to: 'ae', from: '[Æ]'},

Also, I think the first .toLowerCase() is not necessary, since the regex performs a case-insensitive search.

Seems this is not working with Chinese characters: 商务计划模板

Replaced:
.replace(/[^\w\-]+/g, '') // Remove all non-word chars

with

.replace(/[^a-zA-Z0-9_\u3400-\u9FBF\s-]/g, '') // Remove all non-word chars

Also have a look at this:

Thanks, bro!
