feat(backend): project builder init draft #41
Conversation
This commit adds the `ProjectBuilderModule` and `ProjectBuilderService` to the backend codebase. The `ProjectBuilderModule` is responsible for importing the necessary dependencies and providing the `ProjectBuilderService` as a provider. The `ProjectBuilderService` contains the `createProject` method for creating a new project.
This commit adds the `ModelProvider` to the `ProjectBuilderService` in the `ProjectBuilderService` file. The `ModelProvider` is used to retrieve an instance of the `ModelProvider` class. This change allows the `ProjectBuilderService` to access the necessary models for creating a new project.

🧹 Outside diff range and nitpick comments (28)
backend/src/common/model-provider/types.ts (1)
1-4: Consider adding type refinement and documentationThe interface structure is good, but could benefit from these improvements:
- Add JSDoc comments to document the purpose and usage
- Consider using a more specific type for the endpoint URL
+/** + * Configuration for chat stream model endpoints + * @property endpoint - The URL endpoint for the chat stream model + * @property model - Optional model identifier + */ export interface ModelChatStreamConfig { - endpoint: string; + endpoint: URL | `https://${string}`; model?: string; }backend/src/build-system/project-builder.module.ts (1)
4-5: Standardize import paths for better maintainabilityConsider using consistent relative imports for better maintainability. Currently mixing absolute paths (
src/chat/chat.service) with relative paths (./project-builder.service).-import { ChatProxyService } from 'src/chat/chat.service'; +import { ChatProxyService } from '../../chat/chat.service';backend/src/chat/dto/chat.input.ts (1)
19-20: TODO comment needs more contextThe TODO comment lacks specificity about what needs to be done in
model-provider.ts. Consider adding more details about the intended implementation or creating a tracking issue.Would you like me to help create a GitHub issue to track this TODO item with more detailed requirements?
backend/src/build-system/node/project-init.ts (2)
5-7: Consider using constants for handler IDThe handler ID string could be moved to a constants file to maintain consistency and enable reuse across the build system.
// constants.ts export const BUILD_HANDLER_IDS = { PROJECT_SETUP: 'op:PROJECT::STATE:SETUP' } as const; // project-init.ts readonly id = BUILD_HANDLER_IDS.PROJECT_SETUP;
5-20: Consider architectural improvementsTo improve the maintainability and testability of the build system:
- Use dependency injection for required services
- Consider splitting the project configuration logic into a separate service
- Add interfaces for the configuration structure
- Consider implementing a builder pattern for complex project setups
Example structure:
interface IProjectConfigService { getConfiguration(): Promise<ProjectConfig>; } @Injectable() export class ProjectInitHandler implements BuildHandler { constructor( private readonly logger: Logger, private readonly configService: IProjectConfigService, ) {} // ... rest of the implementation }backend/src/build-system/project-builder.service.ts (2)
1-3: Consider using path aliases for importsThe relative imports could be improved using TypeScript path aliases for better maintainability and readability.
-import { ChatProxyService } from 'src/chat/chat.service'; -import { ModelProvider } from 'src/common/model-provider'; +import { ChatProxyService } from '@app/chat/chat.service'; +import { ModelProvider } from '@app/common/model-provider';
6-18: Consider implementing a builder pattern for project creationThe current service structure might become complex as more project creation features are added. Consider implementing a builder pattern with distinct build steps.
Here's a suggested approach:
interface BuildStep { execute(context: BuildContext): Promise<void>; } class BuildContext { constructor( public readonly name: string, public readonly description: string, public readonly metadata: Map<string, any> = new Map() ) {} } class InitializeProjectStep implements BuildStep { async execute(context: BuildContext): Promise<void> { // Initialize project structure } } class GenerateFilesStep implements BuildStep { async execute(context: BuildContext): Promise<void> { // Generate necessary files } } // Update service to use build steps class ProjectBuilderService { private buildSteps: BuildStep[] = [ new InitializeProjectStep(), new GenerateFilesStep(), ]; async createProject(input: { name: string; projectDescription: string; }): Promise<{ projectId: string }> { const context = new BuildContext(input.name, input.projectDescription); for (const step of this.buildSteps) { await step.execute(context); } return { projectId: 'generated-id' }; } }backend/src/build-system/hanlder-manager.ts (2)
1-6: Consider adding readonly modifier for better immutabilityThe implementation looks good with proper type safety. Consider adding the
readonlymodifier to the handlers map to prevent accidental mutations outside the designated methods.- private handlers: Map<string, BuildHandler> = new Map(); + private readonly handlers: Map<string, BuildHandler> = new Map();
20-25: Consider explicit null check for better type safetyThe Singleton implementation is correct. Consider using an explicit null check for better type safety.
static getInstance(): BuildHandlerManager { - if (!BuildHandlerManager.instance) { + if (BuildHandlerManager.instance === null || BuildHandlerManager.instance === undefined) { BuildHandlerManager.instance = new BuildHandlerManager(); } return BuildHandlerManager.instance; }backend/src/build-system/types.ts (3)
3-9: Add JSDoc comments to document the build phases.Consider adding JSDoc comments to describe the purpose and typical use case of each build phase for better maintainability.
+/** + * Represents the main phases in the build system pipeline. + * Each phase represents a distinct stage in the project generation process. + */ export type BuildNodeType = + /** Initial project configuration and setup */ | 'PROJECT_SETUP' + /** Requirements and analysis documentation */ | 'ANALYSIS' + /** Database design and setup */ | 'DATABASE' + /** Backend service implementation */ | 'BACKEND' + /** User experience design */ | 'UX' + /** Web application implementation */ | 'WEBAPP';
27-31: Consider strengthening type safety for the config property.The
configproperty usingRecord<string, any>could lead to runtime errors. Consider:
- Creating specific config interfaces for each BuildNodeType
- Using a discriminated union based on the node type
interface ProjectSetupConfig { // project-specific config properties } interface DatabaseConfig { // database-specific config properties } type BuildNodeConfig = { PROJECT_SETUP: ProjectSetupConfig; DATABASE: DatabaseConfig; // ... other configs } interface BuildNode extends BuildBase { type: BuildNodeType; subType?: BuildSubType[BuildNodeType]; config?: BuildNodeConfig[BuildNodeType]; }
20-25: Add runtime validation for the requires array.The
requiresarray inBuildBaseshould be validated to ensure referenced node IDs exist in the build sequence.Consider implementing a validation utility:
function validateBuildDependencies(node: BuildBase, allNodes: Set<string>): void { if (node.requires) { const missingDeps = node.requires.filter(id => !allNodes.has(id)); if (missingDeps.length > 0) { throw new Error(`Missing required nodes: ${missingDeps.join(', ')}`); } } }backend/src/build-system/__tests__/test.spec.ts (3)
13-32: Consider adding more test sequences for edge casesThe current test sequence only covers the happy path. Consider adding test sequences for:
- Invalid sequence structure
- Multiple parallel steps
- Failed operations
34-40: Add afterEach cleanupConsider adding an
afterEachblock to clean up resources and ensure test isolation:beforeEach(() => { handlerManager = BuildHandlerManager.getInstance(); handlerManager.clear(); context = new BuilderContext(testSequence); executor = new BuildSequenceExecutor(context); }); + afterEach(() => { + handlerManager.clear(); + });
8-8: Add JSDoc comments for test suitesConsider adding descriptive JSDoc comments to improve test maintainability and clarity:
+/** + * Test suite for ProjectInitHandler functionality. + * Verifies handler registration, state management, execution, and identification. + */ describe('Project Init Handler Test', () => {backend/src/chat/chat.resolver.ts (3)
Line range hint
56-80: Add error handling and improve stream managementThe streaming implementation has several areas that could be improved for robustness:
- Add error handling for message saving operations
- Consider using a more memory-efficient approach for content accumulation
- Implement proper cleanup for failed streams
- Add timeout handling for long-running streams
Consider applying these improvements:
const iterator = this.chatProxyService.streamChat(input); -let accumulatedContent = ''; +const chunks: string[] = []; +const streamTimeout = setTimeout(() => { + throw new Error('Stream timeout exceeded'); +}, 300000); // 5 minutes timeout try { for await (const chunk of iterator) { if (chunk) { const enhancedChunk = { ...chunk, chatId: input.chatId, }; await this.pubSub.publish(`chat_stream_${input.chatId}`, { chatStream: enhancedChunk, }); if (chunk.choices[0]?.delta?.content) { - accumulatedContent += chunk.choices[0].delta.content; + chunks.push(chunk.choices[0].delta.content); } } } + const accumulatedContent = chunks.join(''); await this.chatService.saveMessage( input.chatId, accumulatedContent, MessageRole.Model, ); return true; } catch (error) { + await this.chatService.saveMessage( + input.chatId, + 'Error: Message processing failed', + MessageRole.System, + ); this.logger.error('Error in triggerChatStream:', error); throw error; } finally { + clearTimeout(streamTimeout); }
Line range hint
91-98: Improve error handling and type safetyThe current error handling loses valuable context and lacks proper logging. Additionally, the response structure assumption (
models.data) lacks type safety.Consider applying these improvements:
+interface ModelResponse { + models: { + data: Array<{ id: string }>; + }; +} async getAvailableModelTags( @GetUserIdFromToken() userId: string, ): Promise<string[]> { try { - const response = await this.chatProxyService.fetchModelTags(); + const response = await this.chatProxyService.fetchModelTags() as ModelResponse; return response.models.data.map((model) => model.id); } catch (error) { - throw new Error('Failed to fetch model tags'); + this.logger.error('Failed to fetch model tags:', error); + throw new Error(`Failed to fetch model tags: ${error.message}`); } }
Line range hint
1-24: Consider splitting resolver responsibilitiesThe
ChatResolverhandles multiple concerns including chat management, streaming, and model operations. Consider splitting these into separate resolvers (e.g.,ChatStreamResolver,ChatManagementResolver) to improve maintainability and follow the Single Responsibility Principle.Additionally, consider adding input validation using a validation pipe or class-validator decorators for the DTOs.
Example structure:
// chat-stream.resolver.ts @Resolver() export class ChatStreamResolver { @Subscription(() => ChatCompletionChunk) chatStream() { ... } @Mutation(() => Boolean) triggerChatStream() { ... } } // chat-management.resolver.ts @Resolver() export class ChatManagementResolver { @Query(() => [Chat]) getUserChats() { ... } @Mutation(() => Chat) createChat() { ... } // ... other management operations }backend/src/build-system/executor.ts (5)
15-15: Use consistent language for comments (English preferred).The comment on line 15 is in Chinese. For consistency and to improve collaboration, it's advisable to use English for all comments.
Suggested change:
- await new Promise((resolve) => setTimeout(resolve, 100)); // 添加小延迟 + await new Promise((resolve) => setTimeout(resolve, 100)); // Add a small delay
26-93: Consider refactoring to reduce code duplication in retry logicThe retry logic in both the parallel and sequential execution paths within the
executeStepmethod is similar. Extracting this logic into a separate method could improve code maintainability and reduce redundancy.
33-34: Make 'maxRetries' parameter configurableThe
maxRetriesconstant is hardcoded to 10. Consider making it a configurable parameter or passing it as an argument to allow flexibility and ease of testing. This change applies to both parallel and sequential execution paths.
21-22: Consider using a logging framework instead of console methodsUsing
console.errorfor logging may not provide the flexibility needed for larger applications. Consider adopting a logging library (e.g.,winston,pino) to manage log levels and outputs more effectively throughout the application.
101-103: Correct variable name 'incompletedNodes' to 'incompleteNodes'The variable
incompletedNodesmay be better namedincompleteNodesfor clarity and correct English usage.Suggested change:
- const incompletedNodes = step.nodes.filter( + const incompleteNodes = step.nodes.filter( (node) => !this.context.getState().completed.has(node.id), );Also, update references to this variable accordingly.
backend/src/chat/chat.service.ts (2)
25-28: Consider adding error handling in 'streamChat' methodThe
streamChatmethod currently returns the result ofthis.models.chat(...)without handling potential exceptions. To improve robustness, consider implementing error handling to manage any errors that may arise during the chat operation.Suggested change:
streamChat( input: ChatInput, ): CustomAsyncIterableIterator<ChatCompletionChunk> { + try { return this.models.chat(input.message, input.model, input.chatId); + } catch (error) { + this.logger.error('Error occurred while streaming chat', error); + throw error; + } }
32-32: Add error handling in 'fetchModelTags' methodThe
fetchModelTagsmethod directly returns the result ofthis.models.fetchModelsName()without handling possible exceptions. Incorporating error handling will enhance reliability by managing any errors during the fetch operation.Suggested change:
async fetchModelTags(): Promise<any> { + try { return this.models.fetchModelsName(); + } catch (error) { + this.logger.error('Error fetching model names', error); + throw error; + } }backend/src/common/model-provider/index.ts (1)
42-42: Address the TODO: Externalize endpoint to environment variablesThere's a TODO comment indicating that the endpoint should be added to the environment variables. To adhere to best practices, it's recommended to externalize configuration details like endpoints.
Would you like assistance in implementing this change?
backend/src/build-system/context.ts (2)
71-77: Ensure data encapsulation insetDataandgetDatamethodsThe
setDataandgetDatamethods store and retrieve data without cloning. If mutable objects are stored, external modifications can affect the internal state.Consider cloning the data when setting and getting:
setData(key: string, value: any): void { - this.data[key] = value; + this.data[key] = JSON.parse(JSON.stringify(value)); } getData(key: string): any { - return this.data[key]; + return JSON.parse(JSON.stringify(this.data[key])); }
81-81: Use a logging library instead ofconsole.logUsing
console.logis suitable for debugging, but integrating a logging library would provide better control over log levels and output destinations.Consider using a logging library like
winstonordebugfor more structured logging.Also applies to: 85-85

5-7: Verify type compatibility with chat streaming implementation
The type definition looks correct for async iteration. Let's verify its usage in the chat streaming implementation.
✅ Verification successful
Let me try another search strategy to verify the type usage.
Based on the search results, I can now generate the final response:
Type compatibility verified for chat streaming implementation
The CustomAsyncIterableIterator type is correctly implemented and used throughout the codebase:
- Properly used in
ChatProxyService.streamChat()return type - Correctly implemented in
ModelProvider.chat()method with a complete iterator implementation - Type definition is consistent between usage and implementation

+ @IsString()
+ @MinLength(1)
message: string;

12-17:
Enhance createProject method implementation
The current implementation is incomplete and lacks several crucial elements:
- Input validation
- Error handling
- Meaningful return value
- Project creation logic
Consider implementing these improvements:
async createProject(input: {
name: string;
projectDescription: string;
-}): Promise<void> {
+}): Promise<{ projectId: string }> {
+ try {
+ // Validate input
+ if (!input.name || !input.projectDescription) {

+ // 3. Save project metadata
+
+ return { projectId: 'generated-id' };
+ } catch (error) {
+ this.logger.error(`Failed to create project: ${error.message}`);
+ throw error;
+ }
}Let's verify if there are any existing project creation patterns in the codebase:
backend/src/build-system/hanlder-manager.ts (1)
1-35: Verify test coverage and usage patterns
As this is a core component of the build system, we should verify:
- Test coverage for all scenarios
- Proper usage patterns across the codebase
✅ Verification successful
Let me gather more information about the test coverage and implementation details.
Test coverage and usage patterns are well-implemented
The verification shows:
- Comprehensive test coverage including:
- Handler registration
- State management
- Direct handler execution
- Handler ID verification
- Proper singleton usage in
BuilderContext - Clear integration with the build system through
ProjectInitHandler - Appropriate error handling through the type system
The implementation follows good practices with proper initialization, clear handler registration, and well-defined interfaces. The test suite covers all critical functionality of the BuildHandlerManager.

}'
Length of output: 9576
backend/src/build-system/types.ts (2)
1-79: Overall architecture looks solid!
The type system is well-structured and provides a good foundation for the build system. The separation of concerns between different build phases and the flexibility of the node system will support various build scenarios effectively.
11-18: Verify if PROJECT_SETUP should have subtypes.
The PROJECT_SETUP type is defined as never in BuildSubType, but it's included in BuildNodeType. This might indicate an inconsistency in the type hierarchy. Consider either:
- Adding valid subtypes for PROJECT_SETUP
- Documenting why PROJECT_SETUP doesn't have subtypes
✅ Verification successful
Let's search for any usage of PROJECT_SETUP and the BuildNodeType definition to understand the context better and verify if PROJECT_SETUP is used without subtypes consistently throughout the codebase.
PROJECT_SETUP is correctly defined as never for its subtypes
The codebase shows that PROJECT_SETUP is intentionally designed not to have subtypes:
- In the test file,
PROJECT_SETUPis used without any subtype, confirming this design - The type system correctly enforces this through:
PROJECT_SETUPbeing part ofBuildNodeType- Its corresponding subtype being
neverinBuildSubType - The optional
subTypefield inBuildNodeinterface that makes subtypes non-mandatory
This is a valid and consistent type hierarchy where PROJECT_SETUP represents a leaf node in the build system that doesn't require further categorization.

8-14: Imports correctly added for new functionalities
The new imports for ChatInput, NewChatInput, UpdateChatTitleInput, CustomAsyncIterableIterator, and ModelProvider are appropriate and align with the updated implementation.
19-19: Addition of 'models' property enhances class functionality
Introducing the private models property of type ModelProvider is a good practice, facilitating access to model-related methods within the class.
21-22: Proper initialization of 'ModelProvider' in the constructor
Initializing this.models using ModelProvider.getInstance() ensures that the class has access to the singleton instance of ModelProvider, adhering to the intended design pattern.

79-91: Verify handler retrieval using node.id
In the executeNode method, the handler is retrieved using node.id. Typically, handlers are associated with node types rather than unique IDs. Using node.id might lead to issues if handlers are not registered per node instance.

ChatProxyService is injected but unused - Remove from ProjectBuilderModule
The ChatProxyService is injected into ProjectBuilderService but is never actually used in any of its methods. The service should be:
- Removed from the constructor injection in
ProjectBuilderService - Removed from the providers array in
ProjectBuilderModule
This will maintain proper separation of concerns and remove unused dependencies.
🔗 Analysis chain
Consider separating chat-related functionality from build system
The inclusion of ChatProxyService in the ProjectBuilderModule suggests tight coupling between chat and build system functionalities. Consider moving chat-related services to a dedicated module to maintain better separation of concerns.

💡 Codebase verification
🛠️ Refactor suggestion
Review suggestions need adjustment based on existing infrastructure
The review comment needs to be modified based on the codebase analysis:
- The codebase already has a NestJS Logger implementation through LoggingInterceptor, which suggests we should use NestJS's built-in Logger instead of creating a custom logging system.
- No existing project configuration types were found, so this needs to be introduced.
- Error handling patterns are not prevalent in the build system, confirming the need for proper error handling.
Suggested implementation should be adjusted to:
import { Logger } from '@nestjs/common';
import { ProjectConfig } from './types';
constructor(private readonly logger: Logger) {}
async run(context: BuilderContext): Promise<BuildResult> {
try {
this.logger.log('Setting up project...');
const projectConfig: ProjectConfig = await this.getProjectConfiguration(context);
context.setData('projectConfig', projectConfig);
return {
success: true,
data: projectConfig,
};
} catch (error) {
this.logger.error('Failed to setup project', error);
return {
success: false,
error: error instanceof Error ? error.message : 'Unknown error occurred',
};
}
}
private async getProjectConfiguration(context: BuilderContext): Promise<ProjectConfig> {
// Implement actual project configuration logic
throw new Error('Not implemented');
}
// Add to types.ts
interface ProjectConfig {
projectName: string;
path: string;
// Add other necessary configuration fields
}🔗 Analysis chain
Several improvements needed in the run method implementation
The current implementation has several areas that need improvement:
- Replace hardcoded values with actual project configuration
- Use a proper logging system instead of console.log
- Add error handling
- Standardize context data keys
Here's a suggested implementation:
import { Logger } from '../logger';
import { ContextKeys } from '../constants';
import { ProjectConfig } from '../types';
constructor(private readonly logger: Logger) {}
async run(context: BuilderContext): Promise<BuildResult> {
try {
this.logger.info('Setting up project...');
const projectConfig: ProjectConfig = await this.getProjectConfiguration(context);
context.setData(ContextKeys.PROJECT_CONFIG, projectConfig);
return {
success: true,
data: projectConfig,
};
} catch (error) {
this.logger.error('Failed to setup project', error);
return {
success: false,
error: error instanceof Error ? error.message : 'Unknown error occurred',
};
}
}
private async getProjectConfiguration(context: BuilderContext): Promise<ProjectConfig> {
// Implement actual project configuration logic
throw new Error('Not implemented');
}Let's verify if a proper logging system exists in the codebase:

🛠️ Refactor suggestion
Refactor ModelProvider to use dependency injection
The current singleton pattern usage bypasses NestJS's dependency injection system. This makes the code harder to test and violates Inversion of Control principles.
Consider injecting ModelProvider through the constructor:
-private models: ModelProvider = ModelProvider.getInstance();
-constructor(private chatProxyService: ChatProxyService) {}
+constructor(
+ private chatProxyService: ChatProxyService,
+ private models: ModelProvider
+) {}Then provide ModelProvider in your module:
@Module({
providers: [
{
provide: ModelProvider,
useFactory: () => ModelProvider.getInstance()
}
]
})| public static getInstance() { | ||
| if (this.instance) { | ||
| return this.instance; | ||

Fix singleton pattern implementation and avoid 'this' in static methods
In the getInstance() method, using this.instance within a static context can be confusing and may not behave as expected. Additionally, the singleton pattern is incomplete because the newly created instance is not assigned to the static instance variable. To ensure only one instance exists, use the class name ModelProvider.instance instead of this.instance, and assign the new instance to it.
Apply this diff to fix the singleton pattern:
public static getInstance() {
- if (this.instance) {
+ if (ModelProvider.instance) {
- return this.instance;
+ return ModelProvider.instance;
}
- return new ModelProvider(new HttpService(), {
+ ModelProvider.instance = new ModelProvider(new HttpService(), {
// TODO: adding into env
endpoint: 'http://localhost:3001',
- });
+ });
+ return ModelProvider.instance;

Ensure chat() method always returns an iterator
The chat() method is declared to return CustomAsyncIterableIterator<ChatCompletionChunk>, but when no model is selected (i.e., selectedModel is undefined), it returns undefined at line 61. This could lead to runtime errors if the caller expects an iterator.
Consider modifying the method to always return an iterator, even in error cases. For example, you can return an iterator that immediately throws an error when next() is called.
Apply this diff to handle the error case:
if (selectedModel === undefined) {
this.logger.error('No model selected for chat request');
- return;
+ return {
+ next: () => Promise.reject(new Error('No model selected for chat request')),
+ return: () => Promise.resolve({ done: true, value: undefined }),
+ throw: (error) => Promise.reject(error),
+ [Symbol.asyncIterator]() {
+ return this;
+ },
+ };

🛠️ Refactor suggestion
Avoid assignments within expressions for clarity
Assigning values within conditional expressions can make the code less readable and harder to maintain. Consider refactoring the loop to separate the assignment from the condition.
Apply this diff to refactor the loop:

buffer += chunk.toString();
- let newlineIndex;
- while ((newlineIndex = buffer.indexOf('\n')) !== -1) {

buffer = buffer.slice(newlineIndex + 1);

🛠️ Refactor suggestion
Avoid exposing internal state directly
The getState() method returns a shallow copy of the state object, but the Set instances are still references to the original Sets. This could allow external code to modify the internal state unintentionally.
Consider returning a deep copy of the state:
getState(): BuildExecutionState {
- return { ...this.state };
+ return {
+ completed: new Set(this.state.completed),
+ pending: new Set(this.state.pending),
+ failed: new Set(this.state.failed),
