Serve passthrough copy files _directly_ during serve without copying to the output folder

[zachleat]

When using --serve or --watch we needn’t copy any passthrough copy files, just serve them directly from the project directory. For standard builds, the files will be copied as normal.

Suggested at 11ty/eleventy-dev-server#12 and #108 (comment)

Shipping with 2.0.0-canary.12!

Revert to previous behavior with eleventyConfig.setServerPassthroughCopyBehavior("copy");

[zachleat]

Passthrough copy no longer triggers a build during --serve or --watch specifically when using the Eleventy Dev Server. Instead, the Dev Server now serves these files directly from the project directory. Changes to passthrough copy files (despite skipping the build) will still trigger a page reload in your browser.

Hi Zach,

thx for this one.

Just tested the Canary 12 version and it doesn't work when passthrough copy with changing output directory like this :
eleventyConfig.addPassthroughCopy({ 'src/public': '/' });

@seb-celinedesign make sure to file a new issue if you’re still having a problem!

@zachleat That issue has been filed some time ago already #2709
Everything else seems to be working but root is still a trouble.

Note that this option has been swapped to opt-in rather than opt-out in v2.0.0-canary.31.
