Is there existing (or upcoming) functionality around facilitating localdev expedience?  
thinking specifically about contexts where one is editing a single page of a moderately large blog, or manypage site…

something like

> Hugo, please retain the list of the last files saved that triggered a rebuild…  
> if (some/all of) those same files trigger the next rebuild, then chances are _VERY GOOD_ that you don’t need to rebuild **EVERYTHING**

IE

> While in serve mode:  
> if the last render completed \< N (unit-of-time-here) ago  
> and if the asset(s?) that changed dont require rebuilding of other things too  
> (ie a js lib that’s included, or a snippit/template, or some other proto-construct/resource)  
> …  
> then ONLY re-render that page/asset.  
> The idea in my mind is SIMILAR to keeping a tcp session active for a few to see if any straggling data comes across the line before flushing context…

sort-of a post build … soft-finish threshold…  
once the timer runs out, hugo would act like it normally does now on site-build-completion.

I see (at least) a few ways to facilitate a bypass mechanism, for cases where you want to trigger a full rebuild anyways

- disable the feature
- set the settle timer to 0, or 1s.
- wait until the configured ‘settle timer’ runs out
- save a file not in the ‘soft-rebuildable’ filetypes list
- remove a ‘waitfile’
- just restart hugo serve…

Does this already exist? If not, is this an idea that has merit? or am I missing something obvious?

It’s called fast render mode, implemented five years ago, and is enabled by default.

[https://github.com/gohugoio/hugo/pull/3959](https://github.com/gohugoio/hugo/pull/3959)

When you run `hugo server` this appears in the terminal

> Running in Fast Render Mode. For full rebuilds on change: hugo server --disableFastRender
