How to Transform the Output of a String Inside GROQ

Last updated: Jun 23, 2021
Hey all, is it possible to transform the output of a string (inside GROQ)? I’m building a nav schema which is an array of parent, child references. Parent references are optional and I’m falling back to the title specified as the base “slug” for children.
Trying to achieve something like this…


  *[_type == "navigation"] {
    items[] {
      // Can I "slugify" the "title"?
      "slug": coalesce(page->slug.current, title),
      children[] {
        "slug": page->slug.current,
      }
    }
  }
Happy to “slugify” the value returned for slug but was just wondering about the possibility of doing this inside GROQ itself

i don’t believe there is a pattern for this type of replace/string modification in groq

you could however fetch the first child? to be the default slug

i regularly slugify titles for things like FAQ sections though, probably something similar you are after, but i do that in the frontend.

you could also maybe auto-generate a slug in a hidden custom field if you really don’t want to do it in the frontend and don’t want the client to see it in the editor?

Oooh ok I figured that might be the case. Good tip RE the hidden field, I think I’ll just do it client side though 🙂

yeah more control that way, hiding things never ends well.
