Appveyor config also needs to be updated but I'm not sure if they support Node 10 yet. Actually I'm not sure if Travis does either so let's see what happens. 😀🍿

Both support it.

Can you update/rebase the PR and trigger a new build?

Do we plan to remove support for Node 6?

@gaearon @Timer and I discussed dropping support for Node 6. It's in maintenance now. EOL is April 2019.

I will merge some of our recent test improvements into this branch which will re-trigger the tests.

Cool. I'm cool with dropping it

For context, I believe we dropped Node 4 when it entered maintenance (LTS expired), but before EOL.

Normally I'd want to wait for EOL, but the difference in features and speed between 6/8 is so significant I don't think it's worth keeping around until EOL. :)

Ugh. Tests passed on Node 10 for simple and monorepo but failed for install and kitchensink. They just timed out. For the simple test suite it took twice as long to run on Node 10 as it did on Node 8. Still want me to merge this?

I want to get a PR passing before we merge ... what in the world is going on. 😅

I don't know but it's a real mess. Sometimes Travis fails, sometimes Appveyor fails, sometimes they both fail and every once in a while they both miraculously pass. Often they will go from passing to failing and the only difference is a change in the README. 🤷‍♂️

Sounds like some race conditions.

Can you add --timeout 30000 to the mocha calls?

This seems like a bit of an improvement. Kitchensink is very flaky on both Node 8 and 10. It passed on Travis but only because I re-ran it 4 times. It seems to fail in different places with different errors.

Installs is consistently failing on Node 10 at the same place on Travis and Appveyor, although it fails in different ways on both. This could be due to the different version of yarn.

This is what the logs look like on Travis and it just hangs here for 30+ minutes until the test times out:

On Appveyor it actually fails on the same part and this is what the logs look like there:

Can we install the latest Yarn?

I added a before_install script to install the latest version of Yarn on Travis. I'm not sure if it made a difference though. The tests did pass but I had to rerun a couple of them. The old-node test failed because it tried to install Yarn with Node 0.10 which doesn't work.

I'm trying to figure out if I can skip installing Yarn with Node 0.10. Alternatively we could update our old-node test to use Node 4 or 6.

Looks like all the tests are now passing on Travis. I had to restart two of them because they failed to install the latest version of Yarn. It looked like a temporary issue with the Yarn site unrelated to our tests.

Appveyor tests are queued...

🍿

Appveyor!!

It works! 🎉

Updating Yarn seems to make a difference with Appveyor. On Travis the process of updating Yarn itself seems to be a bit flaky. The download failed a couple of times and there was a checksum error another couple of times. I'm not sure if this is an issue with the Yarn download site or with Travis. Either way, this seems like a big improvement.

Should the readme be updated to reflect the drop of Node 6? Right now it states:

You’ll need to have Node >= 6 on your local development machine

The README is based on CRA 1.0. We will be updating all the documentation before 2.0 is released.
