Using GROQ to create an excerpt for a Sanity block
This is a quick tip on how to truncate a Sanity block field to create an excerpt using GROQ.
Fetch an excerpt for a Sanity block
*[_type == "article"] {
"excerpt": array::join(string::split((pt::text(body)), "")[0..255], "") + "..."
}When querying the field using a Sanity Client and GROQ, there is no inbuilt excerpt function, or even a truncate function, so we need to do the steps ourselves.
