In addition to .node-version, support .tool-versions and .nvmrc about nodenv

[elstgav]

nodenv-nvmrc supports this functionality for .nvmrc. See #116 (comment) for why this isn’t supported natively.

Yeah, that makes sense. Thanks @elstgav. I think we can call this closed.

I believe asdf supports .node-version file via options and/or configuration (or perhaps via plugin): https://asdf-vm.com/manage/configuration.html#legacy-version-file

.ruby-version has become a defacto standard in the ruby world, across multiple version managers. So too, .node-version is somewhat broadly supported.

While I obviously can't influence other projects' features, I would say that I think it's in the community's best interest to have as many tools as possible support a single standard file. (who wants to force everyone on the team to use the same tool? conversely, who wants their repo to have half a dozen different files all for ostensibly the same purpose?) @shadowspawn has also done a fantastic job documenting support across tools: https://github.com/shadowspawn/node-version-usage

But also, lastly, I'll plug the https://github.com/nodenv/nodenv-package-json-engine plugin. Considering our repos already have package.json, which already contains an engines.node property for declaring supported runtimes, there's an argument for not even using .node-version at all 😄 . Of course, there's more nuance than that. Libraries that are intended to be installed as dependencies should generally not have a "version locking" file in their repo because as deps, they'll be run across a broad spectrum of runtime versions. By contrast, apps that have a single target deployment runtime should.

All that to say, I definitely think it would be great to have a plugin that does read .tool-versions ;) if someone wants to whip that up.

The following plugins all do variations of the same thing and would be a great template to start from.
