write-redirects.js

const { SiteClient } = require('datocms-client')
const client = new SiteClient(process.env.GRAPHQL_TOKEN)
const fs = require('fs')

export default function () {
  client.items
    .all({ 'filter[type]': 'your_redirect_modelApiKey' }, { allPages: true })
    .then((records) => {
      const array = records.map((el) => {
        return {
          old: el.fieldNameOfOldUrl,
          new: el.fieldNameOfNewUrl,
        }
      })
      let content = ''
      array.forEach((element, i) => {
        content += `${element.old} ${element.new}\n`
      })
      fs.writeFile('./static/_redirects', content, (err) => {
        if (err) {
          console.error(err)
          return
        }
      })
    })
}

need to install "datocms-client" and "fs" in devDependencies
