Control your asset optimization settings from netlify.toml

Netlify deploys include the ability to automatically optimize assets as part of the build process.

Available options like CSS and JS minification, image compression, and pretty URLs allow you to improve the performance of your sites with just a few clicks.

Until now, this feature was only available via the admin interface. We are happy to announce that from today, you’ll also be able to control these options directly in your code as part of your netlify.toml file. Now you can keep your code and configuration all in the same place, and under the same version control.

This also provides very granular control over these optimizations, right down to a per-deploy-context basis. For example, if you want to try out CSS bundle and minify on a specific branch, the settings would look something like:

# Default site wide settings
  skip_processing = true

# Branch specific settings
  skip_processing = false
  bundle = true
  minify = true

We think that this is a useful improvement in the level of control you have over these post-processing steps. It’s something we have been wanting to do for a long time.

Find more details and options in the netlify.toml reference docs and feel free to give it a shot 🙂 — this capability is now live!
