Or rather - it does that unless the file is static, in which case it just calls send_file.īut regardless - the underlying Rack server in the Middleman preview server has the capability to dynamically render pages. That render call dynamically renders through the data and templates and returns a response - all in memory, rather than acting as just a static file server. Then it queries the for the resource that matches, using by_destination_path.Īt that point, it calls render on the Resource object that the sitemap gives back. Process_request runs on all call requests, and it builds a request_path from the Rack environment. In that Rack file, Middleman preview server is doing something like this (as far as I can estimate): It is actually acting as a dynamic server and doing something similar to server-side rendering. Turns out, that's not exactly what it's doing. I thought it was running the equivalent of bundle exec middleman build and then acting as an HTTP server from the generated public/ dir. I had some initial misunderstandings about what the Middleman preview server is doing behind the scenes.

Full MR here.īut even targeting specific destination paths or resources was still taking longer than I think we would like. My first thought was to do something like Chad Wooley's OnlyDebuggedResources extension. In depth details for the interested Initial intuitionĪfter my day off on Friday, and some space away from Middleman, I woke up on Saturday with some inspiration about how we could pick up a lot of efficiency.

Repeat all those changes - observe the difference in speed for the templating changes specifically.

To make sure the existing, expected behavior still works, run NO_CONTRACTS=true bundle exec middleman serve.

This will take the amount of time we're used to (closer to a minute or so).

Refresh the page - Middleman will know that a data file has changed, and it will regenerate the sitemap (since that step is required to render out the YAML content).

This will instruct Middleman to get ready to change the sitemap.

To see what I mean about data files, go make a change to data/topic/application-security.yml.

But it's more like 2-3 seconds, as opposed to the previous 1-2 minutes. Middleman still has to watch and render this file out of thousands.

There's still a couple second delay before the change takes effect.

Reload the page (keep in mind you have to opt in to the livereload option - which may slow you down.

Make an edit to sites/marketing/source/includes/cms/topic/ - I usually just delete an h1 or something that will be noticeable.

Once the server is fully running, visit.

The Middleman server startup time will be about the same as ever - this monkeypatch doesn't kick in until after the server has started at least once.

DISABLE_ON_DISK_REBUILD=true NO_CONTRACTS=true bundle exec middleman serve (you can use -verbose and -instrument as well if you want to see what the call stack looks like/compare it without the new env variable).

This MR provides an opt-in monkeypatch to two internal Middleman methods, which will allow a developer to make changes to Middleman template files without triggering a full sitemap rebuild. Right now the digital experience is exploring these challenges. There have been many epics, issues, MRs, and meetings about it. Developing templates in Middleman with the preview server is exceedingly slow.
