Configure how lastmod date is assigned


Putting this here in case others have run into it.

So my default archetype is:

title: "{{ replace .Name "-" " " }}"
date: {{ .Date }}
publishdate: {{ now.Format "2006-01-02" }}
lastmod: {{ now.Format "2006-01-02" }}
draft: true

Then in my single page template at layouts/_default/single.html I have logic to show the last updated date on a post:

{{ .PublishDate.Format "January 2, 2006" }}{{ if ne .PublishDate .Lastmod }}, last updated {{ .Lastmod.Format "January 2, 2006" }}{{ end }}

This was behaving as expected in my development environment.

But when I would deploy to Netlify, the .Lastmod date was showing the date that the file had last been edited, not the lastmod value I had set in the post’s front matter.

After exploring the docs, I learned that the default configuration for lastmod is to use the Git author date for the last revision of the file. But only if --enableGitInfo is passed, or enableGitInfo = true is set in site config.

Turns out, I had HUGO_ENABLEGITINFO = "true" set in my netlify.toml file.

After spending an hour tracking this down, this is what I get for blindly copy/pasting my netlify.toml file when first creating my site :sweat_smile:
