Handy default Netlify toml file settings

With Netlify it's quite easy to quickly spin up a new website with a lot of good default out the box, but there's a few options that are good to set for both security and seo reasons.

Firstly it's good practice to have some headers set to improve security. For example setting X-Content-Type-Options to nosniff will disable sniffing of mime types. Setting X-Frame-Options to DENY will prevent the website being rendered in a frame on another site and Referrer-Policy of same-origin will reduce the amount of referrer information sent to other websites.

It's also a good idea to setup a redirect on the Netlify subdomain that Netlify will have created for your site. If you don't, then you could find the wrong URL ending up in Google.

for = "/*"
  Referrer-Policy = "same-origin"
  Strict-Transport-Security = "max-age=15768000"
  X-Content-Type-Options = "nosniff"
  X-Frame-Options = "DENY"
  X-XSS-Protection = "1; mode=block"
from = "https://example.netlify.app"
to = "https://example.com/"
status = 301
force = true
