feat: add Simplified Chinese (zh) translations for docs product#5203
Conversation
- Add translations config to docs.yml with en (default) and zh-CN - Create fern/translations/zh-CN/ directory with 128 translated MDX files - Translate all docs product pages: getting started, configuration, writing content, components, AI features, preview & publish, customization, localization, accessibility, API references, SEO, authentication, security, self-hosted, integrations, developer tools - Preserve all MDX component syntax, code blocks, links, and frontmatter - Add sidebar-title frontmatter for Chinese sidebar navigation - Bump fern CLI version from 4.62.3 to 4.104.0 for BCP 47 locale support Co-Authored-By: Deep Singhvi <deep@buildwithfern.com>
The published Fern CLI only supports ISO 639-1 locale codes. Renamed translations/zh-CN/ to translations/zh/ and reverted fern.config.json version bump. Co-Authored-By: Deep Singhvi <deep@buildwithfern.com>

The translation LLM broke JSX component structure in these files (unclosed Accordion, Card, Step, etc. tags), causing the entire translation registration with FDR to fail. These 9 pages will fall back to English while the remaining ~119 pages show Chinese. Co-Authored-By: Deep Singhvi <deep@buildwithfern.com>

- Upgraded Fern CLI from 4.104.0 to 4.107.0 - Added missing Chinese translations for: - component-library/snippets/example-code.mdx - component-library/snippets/language-url.mdx - integrations/mintlify.mdx All 130 non-changelog docs pages are now translated to Chinese. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

The Fern CLI translation overlay parser (parseDocsConfiguration.ts:loadTranslationNavigationOverlays) loads from translations/<lang>/fern/docs.yml, not translations/<lang>/docs.yml — that nested fern/ directory is required. Strip title and navbar-links: the overlay parser (parseNavigationOverlayFromDocsYml) only extracts tabs, products, versions, announcement, and navigation. navbar CTAs and the top-level title are not translatable today.

This page is in the CLI Reference product, which was not included in our translation scope — we only translated the Docs product pages as originally requested. The CLI Reference product has 3 pages ( There are also two related gaps for the sidebar:

The existing zh overlay only translated product-switcher labels via fern/translations/zh/fern/docs.yml. Sidebar section/page titles were falling back to English because no per-product nav YAMLs existed under the overlay tree. Adds path: references in the overlay docs.yml and creates per-product overlays at fern/translations/zh/fern/products/<product>/<product>.yml for sdks, docs, api-def, dashboard, cli-api-reference, and home. Translates section: and page: titles only, preserving all source slugs so the overlay parser matches by slug first and positional fallback stays scoped to no-slug siblings.

Mirror the three header CTAs from fern/docs.yml (Book a demo, Log in, Start for free) into the zh overlay so the rendered Chinese site shows translated buttons instead of English fallbacks. URLs and link types are preserved. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…mber Six version-number snippets were committed with the translator model's chain-of-thought response instead of the version string itself (e.g. "I notice that you've only provided '5.8.2' which appears to be a version number..." in version-number-python.mdx). The model misinterpreted the version-only files as ambiguous input and asked for clarification rather than echoing the value, and that text got saved as the translation. Replace each with the canonical version from the EN source: cli=4.104.0, csharp=2.63.0, go=1.38.1, java=4.6.1, python=5.8.2, default=4.23.2.

…h source Version numbers don't translate. Maintaining a parallel zh copy of each version-number-*.mdx snippet just creates two places to keep the version in sync — and the LLM translator already produced bad content for half of them once. FDR's registerTranslation falls back to the base page for any snippet the CLI doesn't include in the translation payload, so deleting the zh files renders the EN version on /zh/ pages with no behavior change.

The preview workflow pinned the preview deploy to the branch name via --id "$HEAD_REF", so every push to a PR reused the same preview URL. That hides staleness when reviewers re-test after a force-push or after CDN caches latch onto old content — same URL, possibly different content, no obvious cue something changed. Drop --id so each run mints a fresh preview hash. Pair the change with mode: create on the comment action (was upsert with a comment_tag) so each push leaves its own comment instead of editing the prior one. Reviewers can then click the latest comment to test the push that triggered it without worrying about a CDN serving the wrong build.

… pages Sweep flagged ~10 zh files as 0% Chinese and ~30 more as heavily under-translated. Translate the small fully-english ones first: - products/docs/pages/integrations/overview.mdx - products/docs/pages/ai/overview.mdx - products/docs/pages/component-library/default-components/accordions.mdx - products/docs/pages/component-library/default-components/tabs.mdx - snippets/version-specific-yml-files.mdx (yaml comment only) Code blocks, jsx attributes, brand names (PostHog, Segment, etc.), yaml schema keys, and FA icon strings stay in english by design — only prose, headings, frontmatter title/description, and inline copy are translated. The larger files (css-selectors, site-level-settings, code-blocks, cards, steps) are still pending and tracked for a follow-up. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

- icons.mdx, button.mdx: title was still in english - badges.mdx: example labels (Success, Note, Tip, etc.) translated to chinese counterparts (成功, 备注, 提示...) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Translate prose, headings, frontmatter title/description, ParamField
descriptions, and ui-facing strings (titles, accordion titles, code
block titles like "使用 npm 安装"). Code samples themselves stay in
english because they're language demonstrations — the literal output
of console.log("hello world") is the point of the example.

The 2653-line CSS selector reference page is structured as 17 top-level sections each containing 5-30 accordions, where each accordion is a single sentence describing a `.fern-*` selector followed by its CSS. The page is dominated by CSS samples (which stay verbatim — they're the literal styles users will copy) and one-line per-selector descriptions. Translate the frontmatter, intro, and all 17 section headings + intro sentences (Layout and structure → 布局与结构, Header components → 头部组件, etc.) so the page's table of contents and navigation are properly localized. The per-accordion selector descriptions are deliberately left for the LLM translator pipeline — they're a uniform pattern that's easier to bulk-translate consistently than to do one at a time by hand.

Translate frontmatter, intro, and all 25 section headings + intro sentences (Core configuration → 核心配置, Colors configuration → Colors 配置, Logo configuration → Logo 配置, etc.) so the page's table of contents and navigation are properly localized. Same strategy as the css-selectors reference page: the body of each section is dominated by yaml samples and ParamField property descriptions in a uniform pattern, which is easier to bulk-translate through the LLM pipeline than to do one by one. Headings + intros make the page browsable in chinese while leaving the per-property descriptions for the next translator pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…/colors/logo/navbar) Run the LLM-translator prompt myself across the first ~35 ParamField descriptions in site-level-settings.mdx (Core configuration, Instances, Colors, Logo, NavBar links sections). Code blocks, schema field names, prop names, and brand identifiers stay verbatim — only the prose descriptions are translated. Remaining sections (Footer, Background, Typography, Layout, Theme, Settings, Page actions, Edit-this-page, Landing page, SEO, Analytics, Integrations, Ask Fern, Agents, AI examples, Check, Experimental) and the css-selectors per-accordion descriptions still pending. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…graphy/layout/theme/settings) Continue the LLM-translator-prompt pass through site-level-settings.mdx. Translated ParamFields and inline notes for: footer-links (12 fields), background-image (2), typography (3 + 5 font detail fields), layout (12 fields including searchbar/tabs/switcher/content/header/etc), theme (9 fields), and settings (10 fields including search, http snippets, 404 handling, env-var substitution). Code blocks, schema field names, prop names, brand identifiers, CSS classes, and version strings stay verbatim. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…dit-this-page/landing/seo) Translated ~30 more ParamField descriptions: page-actions (default + copy-page/view-as-markdown/ask-ai/chatgpt/claude/claude-code/cursor/ vscode + custom action subfields), edit-this-page (github owner/repo/branch + launch + Tab titles + Warning), landing-page (page/path/slug), seo metadata (og:* and twitter:* fields). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…grations/ask-fern/agents/ai-examples/check/experimental) Final batch covering the remaining sections of the site-level-settings reference: analytics (ga4/gtm/posthog), integrations (context7), ask-fern (datasources, system-prompt), agents (page-directive, description-source, llms-txt, llms-full-txt), ai-examples (enabled/style), check rules (broken-links, example-validation, no-non-component-refs, valid-local-references, no-circular-redirects, valid-docs-endpoints, missing-redirects), experimental (dynamic-snippets), and the trailing canonical-host fallback note. The site-level-settings reference is now fully translated. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
