feast(backend): ux datamap doc #49
Conversation
This commit adds the necessary code changes to generate a UX Data Map document. The `UXDatamapHandler` class is introduced, which implements the `BuildHandler` interface. It includes a `run` method that generates the UX Data Map document based on the provided context data. The `UXDatamapHandler` class uses the `prompts.generateUXDataMapPrompt` function to dynamically generate the UX Data Map prompt. The prompt includes information such as the project name, sitemap documentation, and platform. The generated UX Data Map document is stored in the context using the `setData` method, with the key `uxDatamapDocument`. This feature enhances the project builder functionality by providing a way to generate a UX Data Map document, which helps in analyzing data requirements from a user experience perspective.

backend/src/build-system/node/ux-datamap/index.ts (1)
33-39: Add validation for the generated content.The method should validate the structure and content of the generated document before storing it in the context.
+ // Validate the generated content + if (typeof uxDatamapContent !== 'string' || uxDatamapContent.trim().length === 0) { + context.logger.error('Invalid UX Data Map content generated'); + return { + success: false, + error: 'Generated content is invalid or empty', + }; + } + // Store the generated document in the context context.setData('uxDatamapDocument', uxDatamapContent); return { success: true, data: uxDatamapContent, };backend/src/build-system/node/product_requirements_document/prd.ts (2)
Line range hint
11-19: Consider logging when falling back to default valuesWhile the default fallbacks are good for robustness, it would be helpful to log when these defaults are used to help identify potential configuration issues.
const projectName = - context.getData('projectName') || 'Default Project Name'; + context.getData('projectName') ?? (() => { + this.logger.warn('Project name not found in context, using default'); + return 'Default Project Name'; + })();
Line range hint
1-42: Consider architectural improvementsA few architectural suggestions to improve maintainability and type safety:
- Consider separating prompt management into a dedicated service
- Add type safety for context data using TypeScript interfaces
- Consider implementing a retry mechanism for LLM API calls
Example for context data typing:
interface PRDContextData { projectName: string; description: string; platform: string; }Would you like me to provide a detailed implementation for any of these suggestions?
backend/src/build-system/executor.ts (6)
1-1: Consider using dependency injection for loggerWhile the logger implementation is an improvement over console logging, consider following NestJS's dependency injection pattern by injecting the logger through the constructor instead of creating it internally.
export class BuildSequenceExecutor { - constructor(private context: BuilderContext) {} - private logger: Logger = new Logger(`BuildSequenceExecutor-${uuidv4()}`); + constructor( + private context: BuilderContext, + @Inject(Logger) private logger: Logger + ) { + this.logger.setContext(`BuildSequenceExecutor-${uuidv4()}`); + }Also applies to: 4-4, 9-9
20-20: Make delay duration configurableThe 100ms delay is hardcoded. Consider making this configurable through the context or configuration service.
- await new Promise((resolve) => setTimeout(resolve, 100)); + await new Promise((resolve) => setTimeout(resolve, this.context.getRetryDelay()));
Line range hint
47-48: Extract retry configurationThe retry count and max retries are hardcoded. Consider extracting these to configuration values that can be adjusted based on the environment or build requirements.
+ private static readonly DEFAULT_MAX_RETRIES = 10; + private static readonly DEFAULT_RETRY_COUNT = 0; + private async executeStep(step: BuildStep): Promise<void> { this.logger.log(`Executing build step: ${step.id}`); if (step.parallel) { let remainingNodes = [...step.nodes]; let lastLength = remainingNodes.length; - let retryCount = 0; - const maxRetries = 10; + let retryCount = BuildSequenceExecutor.DEFAULT_RETRY_COUNT; + const maxRetries = this.context.getMaxRetries() ?? BuildSequenceExecutor.DEFAULT_MAX_RETRIES;
Line range hint
121-126: Enhance error handling for incomplete nodes
- Convert warning to error log as per TODO
- Consider cleanup or rollback before early return
- this.logger.warn( + this.logger.error( `Step ${step.id} failed to complete nodes: ${incompletedNodes .map((n) => n.id) .join(', ')}`, ); + await this.cleanup(); // Consider implementing cleanup return;
130-131: Review logging of final stateThe final state might contain sensitive information. Consider:
- Sanitizing the state before logging
- Using debug level for full state
- Logging only essential metrics
this.logger.log(`Build sequence completed: ${sequence.id}`); - this.logger.log('Final state:', this.context.getState()); + this.logger.log('Final state:', this.sanitizeState(this.context.getState()));
Line range hint
1-132: Consider implementing a comprehensive logging strategyWhile the transition to structured logging is good, consider implementing a broader logging strategy that includes:
- Log level standardization across the application
- Correlation IDs for tracing entire build sequences
- Structured logging schema for consistent parsing
- Log sanitization utilities for sensitive data
Would you like assistance in designing this logging strategy?
backend/src/build-system/node/ux-datamap/prompt.ts (3)
32-86: Consider adding accessibility requirements to the data analysis template.The template should include considerations for accessibility needs:
- Screen reader requirements
- Keyboard navigation data
- ARIA attributes and states
- Color contrast requirements
87-129: Review security implications in the login page example.While the login page example is helpful, consider:
- Avoiding specific password requirements in public documentation
- Adding rate limiting considerations
- Including 2FA/MFA data requirements
- Adding session management requirements
132-139: Consider adding validation guidelines for the output format.To ensure consistent and valid output, consider adding:
- Maximum length constraints
- Required sections validation
- Format validation for the markdown structure
backend/src/common/model-provider/index.ts (2)
52-68: Consider enhancing error handling, logging, and performance.The new
chatSyncmethod implementation could benefit from the following improvements:
- Error handling: Add try-catch block to handle potential stream errors.
- Logging: Add debug log at method start for better traceability.
- Performance: Consider using array join for content aggregation.
Here's a suggested implementation:
async chatSync( input: ChatInput | string, model: string, chatId?: string, ): Promise<string> { + this.logger.debug('Starting chat sync', { model, chatId }); + try { const chatStream = this.chat(input, model, chatId); - let content = ''; + const chunks: string[] = []; for await (const chunk of chatStream) { if (chunk.status === StreamStatus.STREAMING) { - content += chunk.choices + chunks.push(chunk.choices .map((choice) => choice.delta?.content || '') - .join(''); + .join('')); } } + const content = chunks.join(''); this.logger.log('Aggregated content from chat stream:', content); return content; + } catch (error) { + this.logger.error('Error in chat sync:', error); + throw error; + } }
52-56: Add JSDoc documentation for the new method.Consider adding JSDoc documentation to describe the method's purpose, parameters, return value, and potential errors.
Add this documentation above the method:
/** * Synchronously aggregates content from a chat stream. * @param input - The chat input as either a ChatInput object or string * @param model - The model identifier to use for chat * @param chatId - Optional chat identifier for conversation tracking * @returns Promise resolving to the aggregated chat content * @throws Error if the chat stream encounters an error */backend/src/build-system/context.ts (1)
88-91: Refine 'ContextData' type for improved type safetyThe current definition of
ContextDataincludes both specific keys andRecord<string, any>, which allows any string keys with any value. This may reduce type safety and negate the benefits of definingGlobalDataKeys.Consider separating global data from other data to enhance type safety. For example:
type GlobalContextData = { [key in GlobalDataKeys]: string; }; type ContextData = GlobalContextData & { [key: string]: any; };Alternatively, if only the global keys are needed, you can remove
Record<string, any>:-} & Record<string, any>; +};Also applies to: 95-98

52-68: Verify complete migration from chunkSync to chatSync.
The removal of chunkSync and addition of chatSync requires verification of complete migration.
✅ Verification successful
Let me gather more specific information about the usage of both methods.
The previous results showed some migration activity, but we need to verify all current usages to ensure complete migration. This will help us confirm if there are any remaining instances of chunkSync that haven't been updated to use chatSync.
Migration from chunkSync to chatSync is complete and verified
The verification shows successful migration:
- No remaining usages of
chunkSyncmethod in the codebase chatSyncis properly implemented inModelProviderclass and used in two locations:backend/src/build-system/node/product_requirements_document/prd.tsbackend/src/build-system/node/ux-datamap/index.ts

💡 Codebase verification
Consider centralizing the model name configuration
The model name 'gpt-3.5-turbo' is used in multiple places with different approaches:
- In
llm-server/src/main.tsit's used as a default value - In
backend/src/build-system/node/ux-datamap/index.tsandproduct_requirements_document/prd.tsit's hardcoded - The type definition in
llm-server/src/type/GenerateMessage.tsshows it's a configurable parameter
Consider:
- Moving the model name to a centralized configuration
- Using the model parameter from the ModelProvider consistently instead of hardcoding
🔗 Analysis chain
Verify model name consistency across the codebase.
The hardcoded model name 'gpt-3.5-turbo' should be consistent with other parts of the codebase.
Let me analyze the actual usage context of the model name to ensure consistency and determine if there's a need for centralized configuration.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash

Use a specific type instead of 'unknown' for 'args' parameter
Using unknown as the type for args reduces type safety and may lead to runtime errors. Consider defining a specific type for args to enhance type checking.
Define a specific type for args and update the method signatures accordingly. For example:
- async run(nodeId: string, args: unknown | undefined): Promise<BuildResult> {
