Calculating with dates

[davidsneighbour]

I am playing around with my Netlify headers/redirection/robots component. Right now I expire locally cached pages by hardcoding this years last day into the file for the Expires header.

Expires: Tue, 31-Dec-2020 23:59:59 GMT+0700

Is it somehow possible in Golang to formulate something like {{ today + 1 year }}?

I know that the cache control header perfectly does what I want to achieve, but there are too many clients, setups and use cases, that ignore that header and look for the Expires header.

Cache-Control: public, max-age=31536000, immutable

See https://golang.org/pkg/time/#Time.AddDate

Netlification … cool.

A little tip, and I’m sure you know about and have considered this:

Hugo Modules allows mono-repos, see https://github.com/gohugoio/hugo-mod-jslibs for an example – the sub folders can be versioned individually.

Perfect. The following does the trick:

Expires: {{ now.AddDate 1 0 0 | dateFormat "Mon, 02-Jan-2006 15:04:05 GMT-0700" }}

(1 for a year, 0 months, 0 days).

I am trying to wrap my head around Hugo modules, at least once a month, last time yesterday and somehow it does not compute, yet… Those modules just don’t show up in my repos. Won’t take much longer to get it running though. I’ll check out hugo-mod-jslibs.

offtopic: hi @bep, can you point me to a doc that describes how to “version” modules in a monorepo for hugo? I did create github packages until I realized that that makes no sense for Go or Hugo at all. Is it just a github release foldername/versionnumber or is there something deeper behind it?

I moved my Hugo components into what I believe to be a monorepo but I am not sure about that last step. https://github.com/davidsneighbour/dnb-hugo

foldername/versionnumber or is there something deeper behind it?

Nothing deeper that I know about; it’s that and you also ned to add the folder to the path when init/importing the module. I think it works great, and removes some administration for modules that are somewhat connected (esp. considering you can do hugo mod get -u ./... from the root to update all upstream deps recursively) …
