fix: resolve dangling .d.ts imports across packages (#920) by harshlocham · Pull Request #922 · TanStack/ai

harshlocham · 2026-07-09T13:02:34Z

Fixes #920.

Published packages were emitting dangling relative imports in dist/**/*.d.ts (e.g. '../utils.js' for a directory barrel that builds to utils/index.js). Under bundler / node16 / nodenext resolution, those specifiers don't resolve, and with skipLibCheck: true consumer types silently degrade to any.

This PR:

Fixes 29 dangling declaration imports across 10 packages by switching barrel imports to concrete module paths (matching the ai-openai pattern: ../utils/client, ../middleware/run, ./tools/index, etc.)
Adds scripts/scan-dangling-dts.mjs and wires pnpm test:dts into test:pr / test:ci so this can't regress
Removes 5 orphaned barrel index.ts files left unused after the import cleanup (knip)
Runs verify-links via tsx instead of node (TypeScript script)
Packages touched
@tanstack/ai, @tanstack/ai-anthropic, @tanstack/ai-bedrock, @tanstack/ai-fal, @tanstack/ai-gemini, @tanstack/ai-grok, @tanstack/ai-groq, @tanstack/ai-mistral, @tanstack/ai-ollama, @tanstack/ai-openrouter

✅ Checklist

I have followed the steps in the Contributing guide.
I have tested this code locally with pnpm run test:pr.

🚀 Release Impact

This change affects published code, and I have generated a changeset.
This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

Bug Fixes
- Improved published TypeScript declarations so generated packages resolve imports correctly in common module resolution modes.
- Reduced the chance of broken package builds caused by unresolved relative imports.
Chores
- Added a new declaration-checking verification step to test and CI workflows.
- Updated package entry points to use more specific export paths for better consistency.

Switch directory-barrel imports (`../utils`, `../tools`, `../middleware`) to concrete module paths so published declaration files resolve under bundler/node16/nodenext. Remove orphaned barrel index files, add a `test:dts` scanner guardrail, and run `verify-links` via tsx.

📝 Walkthrough

Walkthrough

Multiple @tanstack/ai* packages update relative imports that previously referenced directory barrels (../utils, ../tools, ../middleware) to concrete module paths, fixing dangling .d.ts import resolution under bundler/node16/nodenext. Some barrel index files remove now-redundant re-exports. A new scripts/scan-dangling-dts.mjs guardrail script scans built .d.ts files for unresolved relative specifiers, wired into test:pr/test:ci/nx scripts as test:dts. A changeset records patch releases.

Changes

Dangling .d.ts import path fixes and scanner guardrail

Layer / File(s)	Summary
Dangling-import scanner and CI wiring `scripts/scan-dangling-dts.mjs`, `package.json`, `.changeset/tender-otters-tease.md`	New script walks built `dist/*/.d.ts` files, detects unresolved relative import specifiers, prints findings, and exits non-zero on failures; wired into `test:pr`, `test:ci`, and `nx.includedScripts` as `test:dts`; changeset documents patch bumps for affected packages.
ai-anthropic barrel import fixes `packages/ai-anthropic/src/adapters/summarize.ts`, `.../text.ts`, `.../index.ts`, `.../text/text-provider-options.ts`	Adapter and index files switch `../utils`/`../tools` imports to concrete `../utils/client`, `../tools/code-execution-tool`, and `./tools/index` paths.
ai-bedrock client re-export fixes `packages/ai-bedrock/src/index.ts`, `.../utils/index.ts`	Index re-exports and type imports switch to `./utils/client`; `utils/index.ts` drops the redundant barrel re-export.
ai-fal adapters/index client-billing split `packages/ai-fal/src/adapters/{audio,image,speech,transcription,video}.ts`, `.../index.ts`	Utility imports split between `../utils/client` and `../utils/billing`; index re-exports moved to `./utils/client`.
ai-gemini experimental adapter fix `packages/ai-gemini/src/experimental/text-interactions/adapter.ts`	Client/type imports switched from `../../utils` to `../../utils/client`, completing a previously missed fix.
ai-grok adapter fixes `packages/ai-grok/src/adapters/{image,summarize,text,video}.ts`	`GrokClientConfig`/`getGrokApiKeyFromEnv` imports switched from `../utils` to `../utils/client`.
ai-groq adapter and barrel removal `packages/ai-groq/src/adapters/{text,tts}.ts`, `.../utils/index.ts`	Adapters switch `GroqClientConfig` import to `../utils/client`; utils barrel drops client/schema-converter/generateId re-exports.
ai-mistral adapter and barrel removals `packages/ai-mistral/src/adapters/text.ts`, `.../tools/index.ts`, `.../utils/index.ts`	Text adapter uses concrete tool-converter/client/schema-converter paths; tools and utils barrels drop redundant re-exports.
ai-openrouter adapter and index fixes `packages/ai-openrouter/src/adapters/image.ts`, `.../index.ts`	Client and tool type re-exports switched to `../utils/client` and `./tools/index`.
ai core middleware import fixes `packages/ai/src/activities/{generateAudio,generateImage,generateSpeech,generateTranscription,generateVideo}/index.ts`, `.../realtime/types.ts`	Middleware helper and `GenerationMiddleware`/`UsageInfo` type imports switched from `../middleware` barrel to `../middleware/run` and `../middleware/types`.

vite-config: dts extension rewrite mangles directory-barrel imports ('../utils' → '../utils.js' instead of '../utils/index.js') config#401: Addresses the same class of dangling .d.ts directory-barrel import problem, though targeting the Vite rewrite logic upstream rather than per-package source fixes.
