+This branch is a wip adding https://edgejs.dev/

 In `production` mode, `@fastify/view` will heavily cache the templates file and functions, while in `development` will reload every time the template file and function.
 
 _Note: For **Fastify v3 support**, please use point-of-view `5.x` (npm i point-of-view@5)._
