Complete Frontend Development Setup and Comprehensive Testing Documentation

[Copilot]

Summary

Successfully completed the frontend development environment setup for the Agent Workflow Builder and created comprehensive testing documentation. The frontend is now fully operational and ready for backend integration testing.

Changes Made

1. Frontend Environment Setup ✅

Configured and launched the frontend development environment:

• Installed all 281 npm dependencies successfully with zero vulnerabilities
• Created .env file with proper API configuration (VITE_API_URL=http://localhost:8000)
• Updated .gitignore to prevent sensitive files (.env, .env.local) from being committed
• Verified frontend server runs successfully on http://localhost:3000 using Vite v7.1.9

Result: Frontend is fully operational with all UI components rendering correctly, including:

• React Flow-based workflow canvas
• Node palette with 6 node types (Start, Agent, Sequential, Concurrent, Condition, End)
• Execution monitor panel
• Canvas controls (zoom, pan, fit view)
• Action buttons (New Workflow, Save, Validate, Execute)

2. Backend Environment Preparation ✅

Fixed critical package dependency issue:

• Identified and corrected invalid package name in requirements.txt
• Changed azure-ai-openai (non-existent package) to openai>=1.0.0 (correct package that supports both OpenAI and Azure OpenAI)
• Created backend .gitignore to protect sensitive files and build artifacts
• Created .env file from .env.example with proper configuration
• Installed core dependencies (fastapi, uvicorn, pydantic, sqlmodel, python-dotenv)

Result: Backend is ready to start with uvicorn app.main:app --reload

Original prompt

proceed with frontend development and other development tasks included in #file:DEVUI_TESTING_COMPLETE_SUMMARY.md

The user has attached the following files from their workspace:

• agent-workflow-builder/backend/DEVUI_TESTING_COMPLETE_SUMMARY.md

The following is a snapshot of a chat conversation between a user and an AI coding assistant. Prioritize later messages in the conversation.
User: Remaining Tasks:

1. Launch DevUI for agent testing
   Status: Not started (attempted but devui command not working)
   Use Context7, microsoft docs tools to gater information about agent-framework and how to properly run DEVUI. Also review line 1-200 of #file:devui-doc.md for additional information about DEVUI
2. ⏳ Setup frontend environment
   What's needed:
   Navigate to ../frontend directory
   Check if node_modules exists
   Install dependencies with npm install or yarn install
   Create .env file with VITE_API_BASE_URL=http://localhost:8000
3. ⏳ Start frontend development server
   What's needed:
   Run npm run dev or yarn dev
   Vite dev server should start (typically on port 5173)
   Connects to backend API at http://localhost:8000
4. ⏳ Test frontend-backend integration
   What's needed:
   Test agent creation through UI
   Test workflow builder drag-and-drop
   Test execution features
   Check browser console for API errors
   Verify WebSocket connection for real-time updates

AI: I'll help you complete the remaining tasks. Let me start by gathering information about the agent-framework and DevUI, then work through each task systematically.
AI: Now let me get more specific documentation about DevUI from Microsoft Agent Framework:
AI: Perfect! Now I have comprehensive information about DevUI. Let me check the current backend status and then proceed with the tasks:
AI: Great! The agent-framework-devui package is installed. Now let me update the todo and launch DevUI properly:
AI: Now let me try launching DevUI programmatically. First, let me create a simple test script:
AI: Now let's check if the .env file has the required Azure OpenAI configuration:
AI: Good! I can see the .env file has an OPENAI_API_KEY configured. Now let's try launching DevUI:
AI: I see the issue - the Azure OpenAI deployment name is missing. Let me update the test script to use OpenAI instead:
AI:

AI: 

AI: Now let's try launching DevUI again:
AI: I need to update the .env file to include OPENAI_CHAT_MODEL_ID:
AI:

AI: 

AI: Now let's try launching DevUI again:
AI: Let me check the terminal output:
AI: Excellent! DevUI is now running successfully on port 8080! 🎉 The server is up and the browser has opened. Let me update the todo list and move to the next task:
AI: Now let's set up the frontend environment:
AI: Let me check if there's a .env.example file to see what's needed:
AI: Now let's check if node_modules exists and install dependencies:
User: let's test agents in DEVUI first. create test dialouge for me to use with the DEVUI interface
AI: I'll create a comprehensive test dialogue/script for you to use with the DevUI interface at http://localhost:8080. Let me create a test guide document:
AI: Perfect! I've created a comprehensive testing guide for you. Let me also create a quick reference card:
AI: Perfect! I've created two comprehensive test guides for you:

🎬 Recommended Starting Point:

Try this first (from Quick Test #1):

Hello! Can you introduce yourself and explain what you can help me with?

This will verify basic functionality and give you confidence that the agent is working properly.
