New Ukrainian Translation Progress

Read TRANSLATION.md first, then inspect this issue's checklist and comments for an unclaimed leaf page. Translate one available page according to the glossary and style guide, and submit a pull request linked to the relevant checklist entry; completion is a reviewed translation merged into the Ukrainian documentation.

Maintainer List

This list of maintainers and active translators was updated on 2025/12/15. uk.react.dev is looking for a maintainer to help review, translate and maintain the documentation!

• @vldmrkl
• @ithompson4
• @oleksii-polovyi
• @bkatsevych
• @alinkedd (Discord l10n community) ('Apologies for the delayed reviews. I’m doing reviews completely asynchronously and sporadically at the moment.')

For New Translators

To translate a page:

1. Check that no one else has claimed your page in the checklist and comments below. AND PLEASE, TAKE A PAGE WHICH IS LOWER IN HIERARCHY, NOT AN INDEX OR INTRO ONE--THESE DEPEND ON INNER PAGES!
2. Comment below with the name of the page you would like to translate.
3. Fork and clone this repo, translate your page, and submit a pull request back here!

Please take only one page at a time.

Before contributing, read the glossary and style guide to understand how to translate various technical and React-specific terms.

Please be prompt with your translations! If you find that you can't commit anymore, let the maintainers know so they can assign the page to someone else.

For Maintainers

When someone volunteers, edit this issue with the username of the volunteer, and with the PR. Ex:

• Quick Start (@tesseralis) #12345

When PRs are merged, make sure to mark that page as completed!

Main Content

To do before releasing as an "official" translation. Please translate these pages first.

Note that each section has an index page, which needs to be translated too.

Navigation and UI

We suggest to leave most of the UI translation until the end. We plan to do some invasive changes to the website folder layout and components, so postponing this until your translation is almost complete would make it easier to merge the changes from our side later. It might make sense to translate the homepage above the fold early, but leave the rest for later. As individual pages get translated, you can change the page titles in the corresponding sidebar files. Finally, when you're translating the navigation, make sure to test both desktop and mobile layouts.

• Homepage (currently in HomeContent.js) (@alinkedd) #596, #602
• Sidebars (currently in src/sidebar*.json) (@undead404) #551 + every next article should be shipped with its title changed in the sidebar and/or footer; #596 - in progress
• Top-level navigation (currently in TopNav.tsx) (@alinkedd) #596
• Other UI #562 (@alinkedd) #596 #609 #610

When You're Ready...

After everything above is translated, add your language to deployedLanguages in Seo.tsx of the original reactjs/react.dev repository.
