Vincle

Monorepo of high-performance, type-safe tools built around JSX-to-HTML rendering. HTML first, JavaScript only where you opt into it.

Packages

Core

Package	Description
@vincle/core	JSX-to-HTML string renderer. Zero dependencies.
@vincle/flow	Deferred fragments, streaming, and DOM patching: <Slot>, <Defer>, <Include> + Turbo / HTMX / Native / WebPlatform / ESI adapters.
@vincle/vite-plugin	Vite asset integration: <Asset>, assetUrl, manifest resolution.

Tooling

Package	Description

Apps (internal)

App	Description
docs	Documentation site for @vincle/core.
bench	Benchmarks vs @kitajs/html, React, Preact, hono/jsx + A/B revision comparison protocol.

Development

Managed with Bun workspaces and Turbo.

bun install
bun run build    # Build all packages
bun run test     # Run all tests (unit + differential fuzzers)
bun run check    # Type-check everything

The differential fuzzers in @vincle/core run a fixed seed window, so a CI divergence replays from the failure message alone. VINCLE_FUZZ_SEEDS and VINCLE_FUZZ_OFFSET widen or shift it:

VINCLE_FUZZ_SEEDS=100000 bun test src/path-equivalence.test.ts
