# Technical Review: GitHub Projects Implementation
## API Integration Analysis
### Current Implementation Review
#### Project Creation and Configuration
```typescript
// src/infrastructure/github/repositories/GitHubProjectRepository.ts
class GitHubProjectRepository {
async create(data: Omit<Project, "id">): Promise<Project> {
// REVIEW: Missing validation for required fields
// REVIEW: No error handling for rate limits
const query = `mutation($input: CreateProjectV2Input!) {
createProjectV2(input: $input) {
projectV2 { id number title ... }
}
}`;
// Recommendation: Add input validation
const validatedData = await this.validateProjectInput(data);
// Recommendation: Add rate limit handling
try {
const response = await this.withRateLimit(() =>
this.octokit.graphql<CreateProjectResponse>(query, {
input: this.mapToGraphQLInput(validatedData)
})
);
return this.mapToProject(response.data.createProjectV2.projectV2);
} catch (error) {
throw this.handleGraphQLError(error);
}
}
}
```
#### Custom Field Management
```typescript
// Current Implementation
async createField(projectId: string, field: CustomField): Promise<void> {
// ISSUE: Limited field type support
// ISSUE: No validation for field options
// ISSUE: Missing error handling for duplicate fields
}
// Recommended Implementation
async createField(projectId: string, field: CustomField): Promise<void> {
const supportedTypes = ['text', 'number', 'date', 'single_select', 'iteration'];
if (!supportedTypes.includes(field.type)) {
throw new InvalidFieldTypeError(field.type);
}
if (field.type === 'single_select' && !field.options?.length) {
throw new InvalidFieldOptionsError();
}
try {
await this.checkFieldNameUnique(projectId, field.name);
await this.createProjectField(projectId, field);
} catch (error) {
if (error.code === 'FIELD_EXISTS') {
throw new DuplicateFieldError(field.name);
}
throw this.handleGraphQLError(error);
}
}
```
### API Coverage Gaps
#### Missing Endpoints
1. Project Template Management
```typescript
// Needs Implementation
interface ProjectTemplate {
create(template: ProjectTemplate): Promise<void>;
apply(projectId: string, templateId: string): Promise<void>;
list(): Promise<ProjectTemplate[]>;
}
```
2. Workflow Automation
```typescript
// Needs Implementation
interface WorkflowAutomation {
createRule(projectId: string, rule: AutomationRule): Promise<void>;
updateRule(ruleId: string, updates: Partial<AutomationRule>): Promise<void>;
deleteRule(ruleId: string): Promise<void>;
}
```
### Error Handling Improvements
#### Current Issues
1. Generic error handling
2. Missing retry logic
3. Limited error context
#### Recommended Implementation
```typescript
class GitHubErrorHandler {
async withRetry<T>(
operation: () => Promise<T>,
options: RetryOptions = defaultRetryOptions
): Promise<T> {
let lastError: Error;
for (let attempt = 1; attempt <= options.maxAttempts; attempt++) {
try {
return await operation();
} catch (error) {
lastError = error;
if (!this.isRetryable(error) || attempt === options.maxAttempts) {
throw this.enhanceError(error, { attempt, operation: operation.name });
}
await this.delay(this.calculateBackoff(attempt, options));
}
}
throw lastError;
}
private isRetryable(error: any): boolean {
return error.status === 429 || // Rate limit
error.status === 502 || // Bad gateway
error.status === 503; // Service unavailable
}
}
```
### Performance Optimization
#### Current Bottlenecks
1. Multiple API calls for related data
2. No caching implementation
3. Inefficient data mapping
#### Recommended Improvements
```typescript
class CachedProjectRepository implements ProjectRepository {
private cache: Cache;
private repository: ProjectRepository;
async findById(id: string): Promise<Project | null> {
const cacheKey = `project:${id}`;
const cached = await this.cache.get(cacheKey);
if (cached) return cached;
const project = await this.repository.findById(id);
if (project) {
await this.cache.set(cacheKey, project, { ttl: 300 }); // 5 minutes
}
return project;
}
async batchGetProjects(ids: string[]): Promise<Project[]> {
const projects = await Promise.all(
ids.map(id => this.findById(id))
);
return projects.filter((p): p is Project => p !== null);
}
}
```
### Security Enhancements
#### Authentication
```typescript
class GitHubAuthenticator {
private static readonly REQUIRED_SCOPES = [
'repo',
'project',
'write:org'
];
async validateToken(token: string): Promise<boolean> {
try {
const octokit = new Octokit({ auth: token });
const { data } = await octokit.request('GET /user');
const scopes = data.scopes || [];
return this.REQUIRED_SCOPES.every(scope =>
scopes.includes(scope)
);
} catch (error) {
throw new InvalidTokenError();
}
}
}
```
#### Input Sanitization
```typescript
class InputSanitizer {
sanitizeProjectInput(input: ProjectInput): ProjectInput {
return {
...input,
title: this.sanitizeString(input.title),
description: this.sanitizeString(input.description),
// Add specific sanitization for other fields
};
}
private sanitizeString(value: string): string {
return value
.replace(/[<>]/g, '') // Remove potential HTML
.trim();
}
}
```
