Bump node engine to 14

[glensc]

This reflects what is running on CI. and also some of the current dependences already require that version.

Using 14.13.1 for lint-staged ^12:

See:

• Remove implict git add when running pre-commit hooks #1260

See #1252 (comment)

Looks like appveyor’s matrix might need an update too

Line 3 in 9337fac

nodejs_version: "12"

Looks like we ran into chicken-egg problem. I wanted to bump node to 14 to be able to finish commander.js update, but updating @types/node breaks commander integration:

$ tsc -p tsconfig.production.json
node_modules/commander/typings/index.d.ts:26:25 - error TS2689: Cannot extend an interface 'NodeJS.EventEmitter'. Did you mean 'implements'?

26   class Command extends NodeJS.EventEmitter {
                           ~~~~~~

source/platforms/github/GitHubUtils.ts:92:22 - error TS2769: No overload matches this call.

I propose we move on here without @types/node bump, and do that once dependencies are updated, so the bumping can be done.

[glensc]

I've posted @types/node pr separately:

• Update @types/node to ^14 #1259

[glensc]

Who will do the merge now? I see one approval, but it was set before further commits.

and @fbartho you didn't remove your approval after further comments.

[glensc]

What is the process here? seems it's not moving ahead naturally (stalled for 4 days) and it's not described in contributing.md either other than push access is given out easily

PR looks good to me, and there's no CLA on people's spare time on OSS maintenance

[glensc]

nevertheless no answer on merge policies. since I have the mana to merge, should I have merged myself (or who?)? would like to hear some guides or something.

[orta]

Then no, please do not merge yourself, I + @fbartho generally merge most things - the ability to self merge is a system designed to allow for folks to worry less about their dependencies and handle absent maintainers (or folks looking to own sections of the codebase after some time)

this was not the best decision to bump node dependency to v14. Distributed dangerjs might still run without any issues on v12 enviroments, depends what target is used when building it. lint-staged is in devDependencies and hence v14 was required only on dev.

I bumped danger on CI which tested a package on different node versions (still would like to keep that package compatible with nodejs <14) but I'd need to either get rid of danger on nodejs v12 (even if it actually reports back on newer v14+ nodejs versions, it is still in package.json trying to be installed and CI fails)
error [email protected]: The engine "node" is incompatible with this module. Expected version ">=14.13.1". Got "12.22.12"

[glensc]

You probably don't need to run danger for all node versions. you are most likely checking the static code committed to repo, so it doesn't matter what node version was used to run danger.js.

But staying on low versions is not a good option either. the dependencies can't be updated and the dependencies will be reported full of security vulnerabilities.

Maintaining multiple version series probably won't going to work either due lack of manpower.

@falkenhawk you're welcome to stay behind on an older version of DangerJS, the older versions are the ones that are still compatible with Node12.

NodeJS itself no longer supports Node12, and new features for DangerJS can't maintain a wider support range than that, it's just not practical. https://github.com/nodejs/release#release-schedule

What's your real concern here @falkenhawk? You're trying to upgrade to latest DangerJS, but not upgrade to latest NodeJS?

It's common when somebody is testing a special edge case, to use a pattern like patch-package to disable the node engine check on this package. We obviously can't provide support if you're patching things like that, but if you think your use-case would still be fine, you're welcome to remove that Engine check in your code-bases.
