Migrate build and test pipeline to vite-plus

[juliusmarminge]

Summary

• Replace the legacy tsdown/vitest workflow with vite-plus across desktop, server, web, and shared packages.
• Consolidate build and test configs around root-level Vite-based task runners, including new vite.config.ts files and removed Turbo/tsdown config.
• Update the server CLI and CI cache setup to match the new workspace build flow and dependency catalog handling.
• Refresh several type signatures and runtime checks that surfaced during the migration.

Testing

• Install vite-plus: https://viteplus.dev/guide/#install-vp
• Not run locally.
• Expected to pass: bun fmt
• Expected to pass: bun lint
• Expected to pass: bun typecheck
• Expected to pass: bun run test

Note

Medium Risk
Build/test infrastructure is replaced across desktop/server/web, so failures may surface in CI or local workflows despite mostly mechanical changes. Runtime logic changes are minor, but the new bundling/aliasing config affects how packages resolve and ship.

Overview
Switches the workspace build + test toolchain to vite-plus. Desktop/server bundling moves from tsdown to vp pack with new vite.config.ts files, Turbo app configs are removed, and package scripts are updated to use vp for build/dev/test.

Adjusts repo plumbing to match the new flow. CI caching drops .turbo and only caches Bun, docs update the meaning of bun run build, and TypeScript configs now include source-package paths (and exclude their tests) to support the new bundling/TS resolution.

Includes small correctness/type cleanups uncovered by the migration. Many Effect.Effect<..., never>/fiber signatures are loosened, workspace scanning ignores .vite instead of .turbo, and a few UI/test assertions and casts are simplified for stricter typing and more reliable browser tests.

Note

Migrate build, test, and dev pipeline from vitest/turbo/tsdown to vite-plus

• Replaces vitest imports with vite-plus/test across all test files in apps/, packages/, and scripts/.
• Replaces turbo with vp (vite-plus CLI) for monorepo task orchestration in root and per-package package.json scripts (dev, build, test, lint, fmt).
• Replaces tsdown with vp pack for bundling desktop and shared packages; adds vite.config.ts files for apps/desktop, apps/server, apps/web, packages/shared, and packages/contracts.
• Adds path alias resolution for @t3tools/* workspace packages to source files across all vite configs and tsconfig.base.json, removing the need for pre-built outputs during development.
• Workspace directory scanning in WorkspaceEntries.ts now ignores .vite instead of .turbo.
• Removes turbo cache from CI; simplifies cache key to bun.lock only.
• Behavioral Change: Effect.Effect and related types drop explicit never error/environment type parameters throughout the codebase, aligning with updated Effect library conventions.

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Workspace scan no longer ignores Turbo cache
  • Restored .turbo to IGNORED_DIRECTORY_NAMES alongside the newly added .vite, since the migration accidentally replaced it instead of adding .vite as an additional entry.

Workspace scan no longer ignores Turbo cache

Medium Severity

Replacing ".turbo" with ".vite" in IGNORED_DIRECTORY_NAMES makes WorkspaceEntries recurse into old Turbo caches. When Git filtering is unavailable or the folder is outside a Git worktree, .turbo contents can flood indexing, hit WORKSPACE_INDEX_MAX_ENTRIES, and hide real project files from search results.
