Behaviour change (split out of the test commit per review). In AI SDK v6 the useChat `onFinish` callback does NOT fire when the stream errors. A brand-new chat whose very first turn fails would therefore never run the post-turn path: the chat list was not invalidated and the client never adopted the server-created chat id — so the failed chat only appeared in history after a manual refresh (the server already creates the row and stores the error message). Running the same `onTurnFinished()` handler on `onError` makes the failed chat show up immediately. The error itself is still surfaced to the user via the existing `error` state.

React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Babel for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:
- Configure the top-level
parserOptionsproperty like this:
parserOptions: {
ecmaVersion: 'latest',
sourceType: 'module',
project: ['./tsconfig.json', './tsconfig.node.json'],
tsconfigRootDir: __dirname,
},
- Replace
plugin:@typescript-eslint/recommendedtoplugin:@typescript-eslint/recommended-type-checkedorplugin:@typescript-eslint/strict-type-checked - Optionally add
plugin:@typescript-eslint/stylistic-type-checked - Install eslint-plugin-react and add
plugin:react/recommended&plugin:react/jsx-runtimeto theextendslist
