Remove Bun and migrate tooling to Vite+

[SegaraRai]

Summary

• remove Bun from local tooling and GitHub Actions
• migrate tests and benchmarks to Vite+ Test
• replace Bun SQLite coverage with better-sqlite3 for the synchronous Drizzle adapter
• replace Bun shell, glob, and environment APIs with Node.js APIs
• migrate package builds from tsup to Vite+ vp pack while preserving ESM/CJS, declarations, source maps, and development/production conditional exports
• remove redundant standalone tooling dependencies and disable pnpm's automatic installation of unused optional peers
• update migration generation for Prisma 7 and refresh generated Drizzle metadata
• update workspace documentation, LLM documentation, and measured bundle sizes

Why

The repository had moved task orchestration, formatting, and linting to Vite+, but tests, benchmarks, build scripts, SQLite integration tests, and CI still depended on Bun. tsup also duplicated library packaging functionality now provided by Vite+.

This completes the toolchain consolidation so the project uses pnpm, Node.js, and Vite+ consistently. It also removes platform-sensitive fixture symlinks that behaved differently on Windows and Linux.

Impact

There is no intended public API change. The existing package entry points, ESM/CJS formats, declaration files, and development conditional exports are preserved. Historical Prisma 5/6/7 and Drizzle 0.30/0.39/0.44/0.45/1.0 RC compatibility fixtures remain covered.

Updated measured core bundle sizes include:

• binary: 3.37 KiB minified / 1.45 KiB gzipped
• string: 4.15 KiB minified / 1.82 KiB gzipped
• both: 7.24 KiB minified / 2.76 KiB gzipped

Validation

• vp install --frozen-lockfile
• vp run check
• vp run build
• vp run typecheck
• vp run test — 31 files, 157 tests
• vp run bench
• vp run attw
• vp run build:docs
• vp run build:examples
• pnpm peers check
• git diff --check

TypeDoc completes with its existing documentation warnings and no errors.

📝 Walkthrough

Walkthrough

The workspace migrated from Bun-oriented CI, testing, database examples, scripts, and packaging to Vite+, Node.js, Better SQLite, and pnpm. Documentation, migration metadata, Prisma configuration, and example packages were updated accordingly.

Changes

Vite+ and Node.js tooling

Layer / File(s)	Summary
Vite+ build and workspace tooling .github/workflows/*, vite.config.ts, packages/core/vite.config.ts, packages/core/scripts/*, pnpm-workspace.yaml, packages/core/tsconfig.json	CI, builds, tests, benchmarks, scripts, TypeScript settings, and peer handling now use Vite+ and Node.js.
Better SQLite test and example integration packages/core/test/*, packages/core/examples/drizzle-orm-sync/*, packages/core/src/drizzle/runtime-sync.test.ts	Synchronous Drizzle setup and examples now use Better SQLite, with updated migration discovery and driver documentation.
Core tests and benchmarks on Vite+ Test packages/core/src/**/*.test.ts, packages/core/src/lib/*.bench.ts, packages/core/examples/**/*.test.ts	Test imports and assertions were migrated to Vite+ Test, and benchmarks use its bench API.
Example packages and Prisma runtime updates packages/examples/**	Example packages remove Bun-specific dependencies and Prisma runtime settings while updating test imports and shared utility paths.
Migration metadata and documentation packages/core/drizzle/migrations/**, packages/core/README.md, packages/core/public/llms*.txt	Migration metadata was regenerated or reformatted, and documentation now describes pnpm and synchronous database drivers.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Poem

A rabbit hops where Bun once ran,
Vite+ commands now lead the plan.
Better SQLite fills the tray,
Tests and builds go a brighter way.
JSON blooms in tidy rows—
Node-powered carrots for all who knows!
