gatsby logo netlify cms logo

After upgrading to Gatsby v3 I noticed builds on netlify seemed to be taking a long time.

The main component taking time on builds seemed to be netlify cms.

NetlifyCMS React Component #

Changed netlify-cms to use external pre-built js to speed up build times.

The main difference between using the netlify cms react component & using pre-built js from netlify is the post preview when editing in netlify cms.

It is possible to set custom css styles for the preview pane on pre-built netlify-cms using CMS.registerPreviewStyle.

Removed some dependencies which are no longer required for the blog.

netlify.toml Tweaks #

As I had disabled gatsby-plugin-netlify due to a problem with webpack on upgrading gatsby I added some default header rules with basic security headers.

Default Header Rules #

X-Frame-Options = "DENY"
X-XSS-Protection = "1; mode=block"
X-Content-Type-Options = "nosniff"
Referrer-Policy = "same-origin"

Redirects #

A cool feature with netlify is the ability to set redirects allowing me to redirect common RSS uri's (/feed, /rss) to rss.xml

Redirects can also forward to external websites.
I added redirects to my github & twitter profiles. (/gh, /github, /twitter)

[[redirects]]
  from = "/github"
  to = "https://github.com/equk"
  status = 301
  force = true
