Does Sanity expose its built-in slugify function for import?
slugifyfunction for import? I'm running some additional logic inside a custom
slugifyfunction for a slug field, but I'd like to ultimately use Sanity's out of the box function within my custom one.
Sanity doesn't officially export its built-in defaultSlugify function for import, but you can easily replicate it in your custom function. According to a community answer, Sanity's default slugification is just a thin wrapper around the speakingurl package.
Here's what the default implementation looks like:
function defaultSlugify(value, type) {
const maxLength = (type.options && type.options.maxLength) || 200
const slugifyOpts = {truncate: maxLength, symbols: true}
return value ? speakingurl(value, slugifyOpts) : ''
}So if you want to add custom logic while still using Sanity's default behavior, you can install speakingurl and use it in your custom slugify function:
npm install speakingurlThen in your schema:
import speakingurl from 'speakingurl'
{
name: 'slug',
type: 'slug',
options: {
source: 'title',
maxLength: 96,
slugify: (value, type) => {
const maxLength = (type.options && type.options.maxLength) || 200
const slugifyOpts = {truncate: maxLength, symbols: true}
const slug = value ? speakingurl(value, slugifyOpts) : ''
// Add your custom logic here
return `/${slug}` // e.g., add a leading slash
}
}
}This gives you the exact same slugification behavior as Sanity's default, with the flexibility to add your own transformations before or after.
