Add addWatchTarget() option to config

[MadeByMike]

I'm trying to move away from build processes tacked onto the front of SSGs. This little helper makes this much easier. It allows you to add a custom watch target so that I can tell eleventy, when my scss or javascript files change, I want you to rebuild the site.

Here's how I use it:

// Additional watch targets
config.addWatchTarget('./src/scss/'); 
config.addWatchTarget('./src/js/');

The build passed but Travis wigged out... can we re-trigger it?

[zachleat]

Restarted!

[MadeByMike]

Don't get it... same thing happened. Windows test all pass, but the CI doesn't close and will timeout. I ran this locally on Windows and "Works on my Machine" - ideas?

[MadeByMike]

Yay \o/ looks like this was a know issue with Windows builds on Travis. Adding an env var YARN_GPG=no fixed it.

More discussion on this here: https://travis-ci.community/t/build-doesnt-finish-after-completing-tests/288

@zachleat would it be too much to ping you again now that the build is passing?

[zachleat]

Before I merge this just one question: are the watch targets here relative to the input directory or the project root?

[MadeByMike]

@zachleat it eventually uses the addRaw() method of EleventyWatchTargets.js which I think means it's relative to the current working directory? Which is usually the same as the project root. Do you think we want to explicitly make this relative to something?

It looks like this solves #333 and #651. Can't wait for a new release. =)

Yay @zachleat "Only those with write access to this repository can merge pull requests."

[zachleat]

Sorry Mike I’ve been swamped here I’ll try to get to this in the next few days!

[MadeByMike]

@zachleat <3 I know buddy. Take as long as you need.

START THE PARADE

Thank you @MadeByMike, this is a lovely addition 👍

I'm having trouble getting this to work with watching a single file:

  eleventyConfig.addWatchTarget("./components");

Works, but I don't want to watch that entire directory

  eleventyConfig.addWatchTarget("./components/concatenated.njk");

☝️ does not work. Can anyone else duplicate?

[zachleat]

Hey @kevinmpowell please file a new issue!
