feat: upgrade AI SDK from V4 to V5 #2657

devin-ai-integration · 2025-08-12T19:19:44Z

Description

This PR upgrades the Onlook codebase from AI SDK V4 to V5, following the official migration guide. The upgrade involves significant breaking changes across the AI functionality, including package updates, API changes, type system updates, and tool definition modifications.

Key Changes:

Package Updates:

Updated ai from ^4 to 5.0.0
Updated all @ai-sdk/* packages to 2.0.0

Core API Changes:

Removed toolCallStreaming: true (now always enabled)
Changed experimental_repairToolCall to repairToolCall
Updated streaming API from toDataStreamResponse to toUIMessageStreamResponse
Replaced getErrorMessage with onError

Type System Updates:

Message → UIMessage with content → parts structure
CoreMessage → ModelMessage
LanguageModelV1 → LanguageModelV2
Updated UseChatHelpers to include generic type parameter

Tool System Changes:

Changed tool definitions from parameters to inputSchema
Updated ToolCall and ToolInvocation imports to use @ai-sdk/provider-utils

Provider Configuration:

Updated maxTokens to maxOutputTokens
Removed deprecated cacheControl: true option from Anthropic provider

Message Structure:

Changed experimental_attachments to attachments
Updated attachment structure to use mimeType/data instead of contentType/url

Related Issues

Addresses the AI SDK V5 upgrade request from Slack #devin-requests.

Type of Change

Testing

⚠️ Important: TypeScript compilation testing was incomplete due to hanging processes. The AI package builds successfully, but comprehensive type checking needs to be verified.

Completed:

✅ AI package builds successfully (bun build in packages/ai)
✅ All file modifications follow the V5 migration guide
✅ Updated 28 files with proper formatting

Needs Verification:

Full TypeScript compilation (bun run typecheck)
Chat functionality integration testing
Tool execution and streaming
Attachment/image handling
Provider configurations

Screenshots (if applicable)

N/A - Backend/API changes only

Additional Notes

Critical Review Areas:

Type Compatibility: Verify all TypeScript compilation errors are resolved
Tool Functionality: Test that tool definitions with inputSchema work correctly
Streaming Chat: Ensure real-time chat functionality works with new streaming API
Message Handling: Verify chat history, tool calls, and attachments work properly
Provider Integration: Test Anthropic and other AI providers function correctly

Risk Factors:

Large Scope: This upgrade touches core AI functionality across multiple packages
Tool System: Significant changes to tool definitions and imports
Message Structure: Pervasive changes to message types and content structure
Incomplete Testing: TypeScript compilation verification was not completed due to environment issues

Testing Recommendations:

Run cd apps/web/client && bun run typecheck to verify all type errors are resolved
Test chat functionality end-to-end including tool usage
Verify attachment/image uploads work correctly
Test streaming responses in the chat interface
Validate that all AI providers (Anthropic, OpenAI, etc.) work as expected

The test name "truncates repeat tool calls except for the last assistant message" no longer matches its implementation. The test was modified to use simple text messages instead of tool invocations, but it's not actually testing any tool call truncation functionality. Consider either:

Renaming the test to reflect its current purpose (e.g., "converts assistant messages correctly")

Updating the implementation to properly test tool call truncation with the V5 API

This mismatch between test name and implementation could lead to false confidence in the tool call truncation functionality.
