// Server API makes it possible to hook into various parts of Gridsome
// on server-side and add custom data to the GraphQL data layer.
// Learn more: https://gridsome.org/docs/server-api/

// Changes here requires a server restart.
// To restart press CTRL + C in terminal and run `gridsome develop`
