velite

Velite is a TypeScript tool that converts Markdown, MDX, YAML, and JSON files into a type-safe data layer using Zod schema validation. It enables static content management without a traditional CMS, outputting validated data as JSON, TypeScript types, and declaration files for use in any JavaScript framework.

What velite is

Velite processes content files through configurable loaders, validates against Zod schemas, and generates type-safe outputs (JSON, DTS, entry files). Built on native APIs with minimal dependencies, it integrates with build systems like esbuild and supports custom loaders, hooks, and field transformations via context-aware schema parsing.

Quickstart

Get the velite source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/zce/velite.gitcd velite# follow the project's README for install & configuration

Need it deployed, integrated, or customized instead? DEV.co ships production installs.

Best use cases

Static Site Generators and Blogs

Generate type-safe content collections from Markdown/MDX files. Ideal for Next.js, Astro, or SvelteKit blogs where content is versioned in Git and validated at build time.

Documentation Sites with Type Safety

Convert documentation written in Markdown into a structured, validated data layer. Enables IDE autocomplete and compile-time validation for doc references and metadata.

Content-Driven Applications

Build JAMstack applications where content (YAML, JSON, Markdown) is the source of truth. Zod schema validation ensures data integrity before reaching the frontend.

Implementation considerations

  • Requires defining Zod schemas upfront; schema changes mandate content file restructuring and potential rebuild complexity.
  • Build-time processing means content changes require redeployment; not suitable for hot-swapped or user-managed content without additional infrastructure.
  • Relative file and image path handling depends on correct directory structure; misconfiguration can break asset references.
  • Custom loaders and hooks add flexibility but require TypeScript/JavaScript knowledge; team must be comfortable with code-based configuration.
  • Output formats (JSON, DTS, entry files) must align with your framework's expected import patterns; verify compatibility before adoption.

When to avoid it — and what to weigh

  • Real-Time Collaborative Content Editing — Velite is file-based and builds at development/deploy time. Not suitable for systems requiring live, multi-user content editing or immediate published changes without rebuilds.
  • High-Frequency Content Updates — Each content change requires a rebuild. Unsuitable for applications with frequent, user-driven content modifications that need instant publishing.
  • Complex Relational Data Models — Velite handles collections and basic relations but is not a database replacement. If your content requires complex queries, transactions, or relational integrity, use a proper CMS or database.
  • Large-Scale Binary Asset Management — While it supports relative files and images, Velite is optimized for text-based content. Managing thousands of images or media files may require separate asset pipelines.

Security considerations

Velite processes local file content at build time; no network exposure by default. File-based schema validation via Zod reduces injection risks. Ensure custom loaders sanitize untrusted input. If exposing content to user-generated file uploads, add validation layers. No sensitive operations; security posture depends on build environment and content sources.

Alternatives to consider

Contentlayer

Mature, feature-rich content framework with stronger ecosystem integrations (Next.js first-class support), but heavier and tighter coupling to frameworks. Consider if you need more out-of-the-box integrations.

TinaCMS

Git-backed headless CMS with visual editing interface; better for teams needing UI-driven content management. Velite is better for developer-driven, code-first content workflows.

MDX / remark plugins directly

Lower-level approach with more manual configuration. Velite abstracts this complexity; choose direct plugins only if you need highly specialized processing outside Velite's scope.

velite FAQ

Can I use Velite with frameworks other than Next.js?
Yes. Velite outputs framework-agnostic JSON, TypeScript types, and entry files. It works with any JavaScript framework (React, Vue, Svelte, Astro, etc.). Next.js snippets are provided but not mandatory.
Does Velite support dynamic/runtime content loading?
No. Velite is build-time only. Content is processed at build/dev time and output as static files. For runtime content changes, use a CMS or database alongside Velite's output.
What happens if content fails schema validation?
The build fails with detailed validation errors from Zod. This is intentional—Velite ensures type safety by preventing invalid content from reaching your app.
How does Velite handle image and file references?
Velite processes relative file and image paths, resolving them relative to content directories. Paths are preserved in output for framework-specific handling. For CDN/remote assets, use absolute URLs in your content.
