A ready-made Next.js Doc-Like File Tree UI you can fork, run, and customize with the prompt pack below.
What's actually inside
The honest engineer's breakdown — what the Next.js Doc-Like File Treetemplate does, how it's wired, and where it's opinionated.
The Next.js Doc-Like File Tree template replicates the familiar three-column docs layout used by Next.js and Vercel: a collapsible file-tree sidebar on the left, the MDX content in the center, and heading anchors via rehype-slug so visitors can deep-link to any section. The DocFileTree component renders your /docs directory as a nested, clickable hierarchy — open the folder, click a page, and the ContentRenderer fetches and displays that MDX file without a full page reload. The ActivePageHighlight tracks the current route via usePathname() and visually marks the selected page in the tree.
Navigation is wired for both desktop and mobile. On narrow screens the MobileMenuToggle shows a hamburger that slides the DocFileTree in as a shadcn/ui Sheet, keeping the experience usable on phones without rebuilding the layout. A minimal TopNav holds your project name, logo, and an optional GitHub star button.
The honest caveat: the template ships with static sample MDX files, so the DocFileTree order reflects filesystem sort order — not alphabetical, not a curated hierarchy. On most macOS/Linux machines this looks fine, but on Windows the readdir order is non-deterministic. You'll want to either sort after reading or add a nav.config.ts to define page order before your real docs go live. Also, there is no search at all — Algolia or Fuse.js is left as an exercise.

Fork it and get it running
Forking this template takes about 5 minutes. The most important step after forking is replacing the sample MDX files with your real documentation — everything else is cosmetic.
Fork the template from V0 community
Open https://v0.dev/chat/community/ktf7pXgMlQP in your browser and click the 'Fork' button to create a personal copy in your V0 workspace. You'll be redirected to the V0 editor with the template loaded. No account configuration is needed for the template itself to render.
Tip: Make sure you're signed in to V0 before clicking Fork — otherwise the button redirects to a login screen.
You should see: You land in the V0 editor with the docs site visible in the Preview tab, showing sample pages in the DocFileTree sidebar.
Verify navigation and content switching
In the V0 Preview tab, click several pages in the DocFileTree to confirm that navigation and content switching work. Verify that the ActivePageHighlight updates as you click between pages, and that the MobileMenuToggle works by resizing the preview window to a narrow width.
You should see: Clicking doc pages in the sidebar loads different content in the main area. The active page is visually highlighted in the tree.
Locate and replace the sample MDX files
Open the V0 File Explorer (Shift+Cmd+E on Mac) to find the /docs/ or /content/ directory. These MDX files mirror the DocFileTree structure — each file corresponds to one page in the sidebar. Use the V0 Code tab to edit or replace the MDX files directly, or push your own files via the connected GitHub branch.
Tip: If your docs are already written in Markdown, you can rename them .mdx — no front matter is required unless the template reads it.
You should see: Your own content appears in the ContentRenderer when you click the corresponding DocFileTree page.
Customize the TopNav and tree ordering
In the V0 Code tab, find the TopNav component and update the project name/logo text. If the tree order doesn't match what you want, locate the nav config file (often nav.ts or similar) and define the explicit page order. This prevents non-deterministic filesystem ordering from scrambling your sidebar.
You should see: The TopNav shows your project name. DocFileTree pages appear in the order you defined.
Publish to Vercel
Click Share → Publish tab → 'Publish to Production' in the V0 editor. Vercel builds and deploys your docs site in 30-60 seconds. You'll receive a .vercel.app URL that works immediately.
You should see: A live public URL for your docs site is shown. All DocFileTree navigation and MDX rendering work on the deployed URL.
Connect GitHub for automated rebuilds
Click the Git panel in the V0 editor and connect your GitHub account. V0 will create a branch (v0/main-{hash}) that tracks your edits. For ongoing doc updates, set up a GitHub Action via the connected repo that triggers a Vercel redeploy on every push to main — so your team can push MDX files and the docs update automatically.
You should see: The Git panel shows a connected repo. Pushes to main trigger automatic Vercel deployments.
The prompt pack
Copy-paste these straight into v0's chat to customize the Next.js Doc-Like File Treetemplate. Each one names this template's own components — no generic filler.
Populate with your project's docs
Replaces all sample MDX content with real project documentation while preserving the complete navigation shell.
Replace the sample docs content with three pages for my project: Introduction (what this project does, installation), Configuration (env vars table), and API Reference (3 endpoint descriptions with request/response examples). Keep the DocFileTree navigation, ActivePageHighlight, and HeadingAnchor components. Update the TopNav logo text to 'MyLib Docs'.
Style the TopNav and ActivePageHighlight to match your brand
Applies brand colors to the navigation elements without touching MDX content.
Update the TopNav background to a dark slate color (#0F172A) and change the logo text font to Inter via next/font/google. Change the ActivePageHighlight active link color to #6C47FF (purple) and add a left border indicator (2px solid) on the active page item in DocFileTree. Update the ScrollableTreeContainer scrollbar to use the custom color.
Add a version switcher to TopNav
Adds a version selector that updates both the DocFileTree file listing and the URL path prefix.
Add a version dropdown to the TopNav. Support 'v3 (latest)' and 'v2'. Store version-specific MDX files under /docs/v3/ and /docs/v2/ directories. Update the DocFileTree to list files from the selected version's directory. Update the URL structure to /docs/v3/introduction. Default to v3.
Add full-text search with Fuse.js and Cmd+K modal
Adds a keyboard-accessible search modal that indexes all MDX content at build time without requiring an external search service.
Add client-side search to the doc site. At build time, generate a search index from all MDX files (title, excerpt, slug) and save to /public/search-index.json. Add a Cmd+K search modal using shadcn/ui Dialog and Command. On query, use Fuse.js to search the index and show results with title and excerpt snippet. Clicking a result should navigate to the correct doc page and close the modal.
Add Supabase-backed changelog with RSS feed
Adds a database-backed changelog page and an RSS feed endpoint, both linked from the TopNav.
Add a /changelog page to the doc site. Store entries in Supabase: changelog table with columns (id uuid, version TEXT, title TEXT, body TEXT, published_at TIMESTAMPTZ). Build the /changelog page as a Server Component fetching entries ordered by published_at DESC. Add a GET route handler at /api/changelog.xml that returns an RSS 2.0 feed. Add an RSS icon link in the TopNav pointing to /api/changelog.xml. Use NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY env vars.
Gotchas when you extend it
The failures people actually hit when they push this template past its defaults — and the exact fix for each.
Active page in DocFileTree doesn't update when navigating between docsWhy: The active state check uses hardcoded string comparison instead of Next.js usePathname(). On navigation, the component doesn't re-evaluate which page is active.
Fix: Import usePathname from next/navigation in the DocFileTree and compare the current path to each page's href. Mark DocFileTree as a Client Component with 'use client'.
The DocFileTree doesn't highlight the active page after navigation. Convert the active-check logic to use usePathname() from next/navigation and compare it to each doc page's slug/path. Mark DocFileTree as a Client Component with 'use client'.
MobileMenuToggle doesn't close after clicking a doc page linkWhy: The shadcn/ui Sheet open state is local to MobileMenuToggle and doesn't react to route changes. The drawer stays open even after the user navigates to a new doc.
Fix: Add usePathname() from next/navigation to MobileMenuToggle and close the Sheet (setOpen(false)) inside a useEffect that runs when pathname changes.
The mobile doc menu stays open after clicking a link. Add usePathname() from next/navigation to MobileMenuToggle and close the Sheet (setOpen(false)) inside a useEffect that runs when pathname changes.
MDX heading anchors from rehype-slug produce duplicate IDs on pages with shared headingsWhy: rehype-slug generates ids from heading text. If two MDX pages both have an h2 called 'Installation', both produce id='installation'. This only causes problems if all docs are rendered on one page.
Fix: Confirm that each MDX file is rendered as a separate Next.js route at /docs/[...slug]/page.tsx. If all docs render together on a single page, split them into individual dynamic route pages.
Check that each MDX file is rendered as a separate Next.js route, not concatenated on one page. If all docs render together, split them into individual dynamic route pages at /docs/[...slug]/page.tsx.
DocFileTree shows pages in random orderWhy: fs.readdir returns files in filesystem order, which varies by OS and is not guaranteed alphabetical. On Windows especially, the order is non-deterministic between deploys.
Fix: Add a sort step after reading the directory: files.sort((a, b) => a.localeCompare(b)). Better: add a nav.config.ts that defines the page order explicitly and use it to sort the tree.

Template vs. custom — the honest call
A forked template gets you far, fast. Here's where it holds up, and where you'll outgrow it.
The template is enough when
- Your project has a well-defined static doc structure that maps naturally to a file tree
- You want a Next.js-native docs site you fully own with no vendor lock-in
- You're launching an OSS library and need docs up before the Product Hunt post
- Your docs content team is comfortable editing MDX files via GitHub
Go custom when
- Your docs grow beyond 200 pages — the file tree metaphor becomes unwieldy at scale
- You need live collaborative editing of docs by non-technical writers (requires a CMS like Sanity or Contentful)
- You need search across thousands of entries (requires Algolia indexing pipeline, not included)
- You need internationalized docs — i18n MDX routing is non-trivial to add to this structure
RapidDev builds production documentation sites from V0 starters — Algolia search, versioning, analytics, and CI/CD included.
Frequently asked questions
Is this template free to use?
Yes. The Next.js Doc-Like File Tree template is a community template on v0.dev — forking it is free. V0's free plan includes a monthly credit allowance; forking itself doesn't consume credits, but subsequent AI edits in the chat do.
Can I use this template commercially?
Yes. V0 community templates can be used for commercial projects. The underlying libraries (Next.js, shadcn/ui, next-mdx-remote, rehype-slug) are all MIT-licensed. Review each library's license if you redistribute the template code itself.
Why does my fork break in preview when I add the Supabase changelog?
V0's preview sandbox loads dependencies via esm.sh. The @supabase/ssr package sometimes fails with 'Import Error | Failed to load @supabase/ssr from blob...' in the sandbox. This is a known V0 preview limitation — the feature works correctly after deploying to Vercel. Deploy first, then test.
How do I add search to the docs site?
The template ships without search. The medium-difficulty prompt on this page covers adding Fuse.js client-side search with a Cmd+K modal. For larger doc sites (hundreds of pages), replace Fuse.js with Algolia DocSearch — the integration requires an Algolia account and a crawl of your deployed site.
How do I connect a real database to this template?
The template is MDX-file-based with no database by default. To add a database, the most common pattern is to connect Supabase: set NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY in V0's Vars panel, then use createServerClient from @supabase/ssr in Server Components. The advanced prompt on this page walks through the changelog table use case.
Why does the DocFileTree show pages in a random order?
The sidebar reads your /docs directory using Node's fs.readdir, which returns files in filesystem order — non-deterministic across OSes. Fix it by sorting the array after reading (files.sort((a, b) => a.localeCompare(b))) or by adding a nav.config.ts that defines the explicit page order.
Can RapidDev help customize this template for my project?
Yes. RapidDev takes V0 doc starters further — adding Algolia search, automated doc versioning, GitHub Actions CI/CD, and design-system alignment. If your doc requirements outgrow what V0 can scaffold in chat, that's the right time to reach out.
Does this template support dark mode?
The template uses shadcn/ui which has class-based dark mode built in. You may need to add a theme toggle to the TopNav if the starter doesn't include one — use the 'Style to match your brand' prompt on this page and mention adding a dark/light toggle to the TopNav.
Outgrowing the template?
RapidDev turns v0 prototypes into production apps — real auth, database, and payments — at $13K–$25K.
