https://fedoraproject.org/wiki/Changes/Nodejs16 == Summary == The latest release of Node.js to carry a 30-month lifecycle is the 16.x series. As with 14.x, 12.x, 10.x and 8.x before it, Fedora 35 will carry 16.x as the default Node.js interpreter for the system. The 14.x and 12.x interpreters will remain available as non-default module streams. == Owner == * Name: [[User:zvetlik| Zuzana Svetlikova]] * Email: zsvetlik@xxxxxxxxxx * Name: [[User:Sgallagh| Stephen Gallagher]] * Email: sgallagh@xxxxxxxxxxxxxxxxx * Responsible SIG: Node.js SIG == Detailed Description == Fedora 35 will ship with the latest LTS version of Node.js. '''dnf install nodejs''' will give users nodejs-16.x and the matching npm package. == Benefit to Fedora == Node.js is a popular server-side JavaScript engine. Keeping Fedora on the latest release allows us to continue tracking the state-of-the-art in that space. For those whose applications do not yet work with the 16.x release, Fedora 35 will also have the 14.x and 12.x releases available as selectable module streams. == Scope == * Proposal owners: The packages are already built for Fedora 33, 34 and 35 in a non-default module stream. On June 14th, 2021, the nodejs-16.x packages will be built in the non-modular repository and thus become the default in Fedora 35. * Other developers: Any developer with a package that depends on Node.js at run-time or build-time should test with the 16.x module stream enabled as soon as possible. Issues should be reported to nodejs@xxxxxxxxxxxxxxxxxxxxxxx * Release engineering: We will coordinate with the Node.js SIG to create a side-tag to perform the rebuilds before making 16.x the default. * Policies and guidelines: N/A (not needed for this Change) * Trademark approval: N/A (not needed for this Change) == Upgrade/compatibility impact == As with previous releases, users running Fedora 33 or Fedora 34 with the non-modular nodejs-14.x packages will be automatically upgraded to the 16.x packages when they upgrade to Fedora 35, which may cause issues. If users are running software known not to support Node.js 16.x yet, they can switch the system to use 14.x with '''dnf module''' commands. == How To Test == * Confirm that `dnf install nodejs` results in Node.js 16.x being installed. * Confirm that upgrading from Fedora 33 or Fedora 34 with nodejs-14.x installed (non-modular) results in an upgrade to nodejs-16.x * Confirm that upgrading from Fedora 33 or Fedora 34 with the `nodejs:14` module enabled does *not* result in an upgrade to 16.x and still has `nodejs:14` enabled on Fedora 35. * Confirm that upgrading from Fedora 33 or Fedora 34 with the `nodejs:16` module enabled upgrades successfully and still has `nodejs:16` enabled on Fedora 33. == User Experience == Users will have the 16.x release of Node.js available by default. See the "Upgrade/compatibility impact" section for specific details. == Dependencies == All packages prefixed with `nodejs-` depend on this package. If they do not work with Node.js 16.x, they will need to be updated, made modular and dependent upon the `nodejs:14` stream or else removed from Fedora 35. Prior to the switchover date to Node.js 16.x as the default, packagers are strongly encouraged to test their existing Node modules with 16.x via the Modular version by running: <pre> dnf module reset nodejs dnf module install nodejs:16/development </pre> Packagers can also test their builds using `mock` by creating the file `/etc/mock/fedora-rawhide-x86_64-nodejs16.cfg` with the following contents: <pre> config_opts['target_arch'] = 'x86_64' config_opts['legal_host_arches'] = ('x86_64',) config_opts['enable_disable_repos'] = ['--enablerepo', 'rawhide-modular'] config_opts['module_install'] = ['nodejs:16/development'] include('templates/fedora-rawhide.tpl') </pre> Then call <pre> mock -r fedora-rawhide-x86_64-nodejs16 --enablerepo=rawhide-modular nodejs-foo </pre> (Note that the `--enablerepo=rawhide-modular` portion looks redundant, but this is because of [https://github.com/rpm-software-management/mock/issues/591 a mock bug]) == Contingency Plan == * Contingency mechanism: Revert to Node.js 14.x as the default Node.js interpreter. This will require bumping epoch. * Contingency deadline: Beta Freeze * Blocks release? No * Blocks product? No == Documentation == * https://nodejs.org/dist/latest-v16.x/docs/api/ * https://github.com/nodejs/node/blob/master/doc/changelogs/CHANGELOG_V16.md == Release Notes == Fedora 35 now ships with Node.js 16.x as the default Node.js JavaScript server-side engine. If your applications are not yet ready for this newer version, you can revert to the 14.x series by running the following commands <pre> dnf remove nodejs dnf module reset nodejs dnf module install nodejs:14 </pre> -- Ben Cotton He / Him / His Senior Program Manager, Fedora & CentOS Stream Red Hat TZ=America/Indiana/Indianapolis _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
