Using `urlFor()` to generate OG image URL in Sanity

const { createClient } = require('@sanity/client')
import imageUrlBuilder from '@sanity/image-url'

const client = createClient({
  projectId: process.env.SANITY_STUDIO_PROJECT_ID,
  dataset: process.env.SANITY_STUDIO_PROJECT_DATASET,
  useCdn: false, // set to `false` to bypass the edge cache
  apiVersion: process.env.SANITY_API_VERSION, // use current date (YYYY-MM-DD) to target the latest API version
  token: process.env.SANITY_SECRET_TOKEN, // Only if you want to update content with the client
})

const builder = imageUrlBuilder(client)

export const clientCheck = client
  .fetch(`count(*)`)
  .then(data => console.log(`Number of documents: ${data}`))
  .catch(console.error)

export const getOgImage = async source => {
  return builder.image(source)
}
