Exclude Analytics When Running Hugo Server
By Godwin Udofia in October 2022 ~ Hugo

Build drafts when serving

Run the hugo server command with the -D flag to build drafts: hugo server -D

I usually have an npm run serve script in package.json that runs chores like building search index, creating OpenGraph and twitter images, etc. before serving my hugo site locally.

{
  "scripts":{
    "serve": "npm run prebuild && hugo server -D"
  }
}

Exclude if drafts are built

.Site.BuildDrafts returns true when hugo server -D runs. Therefore it can be used to conditionally exclude the analytics scripts from the head when serving locally.

{{ if not .Site.BuildDrafts }}
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'G-XXXXXXXXXX');
</script>
{{ end }}

When hugo is run without the -D flag, the analytics section will be included as expected.
