Read from cache when watching

[groenroos]

Is it possible to configure fetch to always load from remote when doing the initial build (effectively duration: '0s'), but then always read from cache when the site is re-built via live reload (i.e. when running Eleventy with the --watch flag)?

We're using fetch to get content from an external CMS, and while always fetching the latest data in the initial build is important (so we have the latest content to work against), I'd want subsequent live re-builds to read from cache, so that some simple template tweak doesn't take 14s+ to build when every CMS endpoint is hit again.

I do not think eleventy-fetch can see what is going on build-wise.

But would this be solved by making sure you empty the cache folder before you start the build? Then it should only fill the cache once at the start. You could use something like rimraf right at the start of your build-watch process.
