[Question] What versions of Node.js does Playwright support?

[rwoll]

What version(s) of Node.js does Playwright official support?

See #1988 and #1989 for related issues/MRs.

If there is an official supported version set, I'll re-open #1989; if there's no official set, please mark this issue as closed.

Hey, #1988 was a bug in Node.js 14 (which should be normally very rare) and in general Playwright supports Node.js 10.15+ see here which will be also covered soon on the website.

[rwoll]

Is it helpful to have the checks in #1989 to ensure the compatibility guarantees, or does that mostly just slow down builds without much benefit since #1988 bugs are likely rare?

I also may be missing a CI config where Playwright already does an equivalent build matrix proposed in #1989.

We target earliest Active LTS Node.js version - which is currently 12. I wouldn't run all our tests on all node.js versions - that's probably too much, but we can run smoke tests on even node.js versions.

We already have test-package-installations tests that verify that playwright installs and runs a simple playwright script. I'd run this on node 14 as well.

@rwoll are you interested in contributing this?

@aslushnikov ,it is still relevant. I am getting an error when running npx playwright install on Node 10.16.3:
Does this mean Playwright is no longer compatible with Node version 10? On 14 everything is fine.

PS C:\Users\t\Documents\Projects\test> npx playwright install
C:\Users\t\Documents\Projects\test\node_modules\@playwright\test\lib\grid\gridServer.js:143

@jevgenijusmarinuskinas Node.js 12+ is required. Node.js 10 is not supported anymore by Node.js and we only support maintained versions.
