"remove" property on options aren't working correctly

[dhanielsales]

Hello guys,

I'm using the property remove on options and i haven't has the correct result. I will post the situation below.

import slugify from 'slugify'

const text = 'Natação foo % ® sdf'

const foo = slugify(text, {
  replacement: ' ',
  lower: false,
  remove: /[*+~.'"!?;:@%$#&=§ªº°·─®]/g,
})

console.log(foo)

// Console Output: 
// Natacao foo percent (r) sdf

Even putting in remove a regex with % it is still replaced by the word percent. The same result for ®.

If I'm doing something wrong, please let me know and I'll retract.

The version i'm using is 1.6.5

remove takes effect after all the characters in the string have been processed. It doesn't operate directly on the input.

You probably want to use extend instead:

slugify.extend({ '%': '', '®': '' })

const foo = slugify(text, {
  replacement: ' ',
  lower: false,
})

Another option would be to use the slug module instead of slugify, as the current version (5.3.0) has the behavior you want (ignoring symbols like % and ®) by default.

import slug from 'slug'

const text = 'Natação foo % ® sdf'

const foo = slug(text, {
    replacement: ' ',
    lower: false,
})

console.log(foo) // Natacao foo sdf
