fix(svelte-devtools): publish compatible adapter exports - #502
Conversation
📝 WalkthroughWalkthroughThe Svelte adapter now manages TanStack Devtools core and Svelte plugin component lifecycles. The package exposes Svelte-aware export conditions and uses Svelte packaging, runes configuration, and type checking. ChangesSvelte adapter package
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR changes published Svelte adapter behavior and dependency installation policy. Runtime configuration updates can still be ignored, while the new chokidar trust-policy exception weakens downgrade protection; these bounded risks should be fixed or explicitly accepted before merging.

Fix configuration updates across the adapter-core boundary.
TanStackDevtoolsCore.setConfigmerges its argument directly into the effective config. This call passes{ config, eventBusConfig, plugins }, so changed config values become a nestedconfigproperty instead of replacing the active configuration. The mounted devtools UI does not receive later config updates.Change the core update contract to merge
init.configinto its internal configuration. Define separate behavior for runtimeeventBusConfigchanges, because the current core method also does not apply that field to an existing event bus.🤖 Prompt for AI Agents

Closes #501
🎯 Changes
Rename devtools.svelte.ts to devtools.ts so generated adapter code is not treated as a Svelte runes module.
Package the adapter with svelte-package, publishing the component as Svelte source and generating Svelte 5 component types to match tanstack/ai
Add the exact chokidar@4.0.3 trust-policy exception required by svelte-check, consistent with tanstack/ai pnpm-workspace.yaml#L18 as well.
Add the svelte export condition while preserving import and type exports.
Validate the package with svelte-check and explicit runes configuration.
Prevent standard Svelte/Vite consumers from recompiling generated code containing svelte/internal/client.
Update the patch changeset for @tanstack/svelte-devtools.
