Add Repository Summary Stats API Endpoint (Git-First Approach)

[jonasyr]

Add Repository Summary Stats API Endpoint for Frontend UI Redesign

📋 Summary

Implement a new backend API endpoint /api/repositories/summary to provide comprehensive repository statistics for the frontend UI redesign. This endpoint uses a Git-first approach with sparse/shallow cloning to avoid GitHub API rate limiting issues while minimizing bandwidth and disk usage.

🎯 Motivation

The frontend redesign (issue #87) includes a "Repository Summary" card displaying key repository metrics:

• Repository name and owner
• Created date and age
• Last commit date
• Total commits count
• Contributors count
• Repository status (active/inactive)

Currently, these values are mocked. The backend needs to expose this data through a dedicated endpoint that primarily uses Git operations to avoid rate limiting problems in multi-user deployments.

🚨 Why Git-First + Sparse Clone?

Rate Limit Problem:

• GitHub API: 60 requests/hour per IP (unauthenticated)
• All users share the same backend server IP
• With 10 concurrent users, rate limit exhausted in 6 minutes!

Git-First Solution:

• ✅ No rate limits - unlimited local Git operations
• ✅ No external dependencies - works offline
• ✅ Fast - local operations are instant
• ✅ Scalable - works for unlimited users
• ✅ Privacy - no data sent to external APIs
• ✅ Universal - works for GitHub, GitLab, Bitbucket, self-hosted

Sparse Clone Optimization (95-99% bandwidth reduction):

• ✅ Uses existing getFileTreeSparse() pattern from fileAnalysisService.ts
• ✅ Downloads ONLY tree structure, no file contents (--filter=blob:none)
• ✅ Shallow clone with --depth=1 (latest commit only)
• ✅ Single branch (--single-branch)
• ✅ No checkout (--no-checkout)
• ✅ Existing infrastructure: Already battle-tested in production

Trade-offs:

• "Created date" is approximate (first commit date) vs exact (GitHub API) → Acceptable for 99% of use cases
• Requires minimal Git clone instead of zero network calls → Still 95-99% faster than full clone

✅ Requirements / Acceptance Criteria

API Endpoint

• Create GET /api/repositories/summary endpoint
• Accept repoUrl as query parameter
• Return structured JSON with all required stats
• Implement proper validation and error handling
• Add rate limiting (reuse existing middleware)

Data Extraction (Sparse Clone Optimization)

• Use sparse clone with --filter=blob:none --depth=1 --single-branch --no-checkout
• Parse repository URL to extract platform, owner, and repo name
• Get first commit date via git log --reverse --max-count=1
• Get last commit info via git log -1 --format=%aI|%H|%an
• Count total commits via git rev-list --count HEAD
• Count unique contributors via git shortlog -s -n --all | wc -l
• Calculate repository age from first commit date
• Determine status based on last commit recency
• Clean up temp directory after extraction

Response Format

{
  "repository": {
    "name": "analytics-pro",
    "url": "https://github.com/octo-org/analytics-pro.git",
    "owner": "octo-org",
    "platform": "github"
  },
  "created": {
    "date": "2019-06-14T10:30:00.000Z",
    "source": "first-commit"
  },
  "age": {
    "years": 5,
    "months": 5,
    "formatted": "5.7y"
  },
  "lastCommit": {
    "date": "2025-11-17T14:23:00.000Z",
    "relativeTime": "2 days ago",
    "sha": "abc123def456",
    "author": "John Doe"
  },
  "stats": {
    "totalCommits": 3482,
    "contributors": 24,
    "status": "active"
  },
  "metadata": {
    "cached": true,
    "dataSource": "git-sparse-clone",
    "createdDateAccuracy": "approximate",
    "bandwidthSaved": "95-99% vs full clone",
    "lastUpdated": "2025-11-19T10:30:00.000Z"
  }
}

Caching Strategy

• Cache summary data for 24 hours (Git data is stable)
• Use cache key: repo:summary:${hash(repoUrl)}
• Integrate with existing multi-tier cache (Redis → Disk → Memory)
• Use repositoryCoordinator to prevent duplicate clones
• Cache remains valid until new commits (commit-hash based validation)

Edge Cases

• Handle empty repositories (0 commits)
• Handle very large repositories (>100k commits) efficiently
• Handle repositories with single commit
• Handle network timeouts during clone
• Handle corrupted Git repositories
• Handle deleted/moved repositories
• Support all Git URL formats (HTTPS, SSH, .git suffix optional)
• Clean up temp directories on error

Type Safety

• Add RepositorySummary interface to @gitray/shared-types
• Add RepositoryStatus type: 'active' | 'inactive' | 'archived' | 'empty'
• Add DataSource type: 'git-sparse-clone' | 'git+github-api' | 'cache'
• Add CreatedDateSource type: 'first-commit' | 'github-api' | 'gitlab-api'

🛠️ Implementation Plan

1. New Service: repositorySummaryService.ts

Location: apps/backend/src/services/repositorySummaryService.ts

Core Functions:

// Main orchestrator - Sparse clone approach
async function getRepositorySummary(repoUrl: string): Promise<RepositorySummary>

// Parse repository URL
function parseRepositoryUrl(repoUrl: string): RepositoryUrlInfo

// Sparse clone for metadata extraction (NEW - based on fileAnalysisService pattern)
async function getSummaryViaSparseClone(repoUrl: string): Promise<{
  firstCommit: string;
  lastCommit: {date: string, sha: string, author: string};
  totalCommits: number;
  contributors: number;
  tempDir: string;
}>

// Git operations (can be run on sparse clone)
async function getFirstCommitDate(repoPath: string): Promise<string>
async function getLastCommitInfo(repoPath: string): Promise<{date, sha, author}>
async function getContributorCount(repoPath: string): Promise<number>

// Calculations
function calculateRepositoryAge(createdDate: Date): AgeInfo
function determineRepositoryStatus(lastCommitDate: Date): RepositoryStatus

// Cleanup
async function cleanupSparseClone(tempDir: string): Promise<void>

Sparse Clone Implementation (based on existing pattern):

async function performSparseCloneForSummary(repoUrl: string): Promise<string> {
  const tempDir = await fs.mkdtemp(path.join(os.tmpdir(), 'gitray-summary-'));
  const git = simpleGit(tempDir);
  
  try {
    // Initialize repo
    await git.init();
    await git.addRemote('origin', repoUrl);
    
    // Sparse clone with maximum optimization
    await git.raw([
      'fetch',
      '--filter=blob:none',  // Exclude file contents (blobs)
      '--depth=1',           // Only latest commit
      'origin',
      'HEAD'
    ]);
    
    await git.raw(['checkout', 'FETCH_HEAD']);
    
    return tempDir;
  } catch (error) {
    await cleanupSparseClone(tempDir);
    throw error;
  }
}

Git Commands on Sparse Clone:

# All these work on sparse clone (no blobs needed):

# First commit date (repository "creation")
git log --reverse --format=%aI --max-count=1

# Last commit info  
git log -1 --format=%aI|%H|%an

# Contributor count
git shortlog -s -n --all | wc -l

# Total commits
git rev-list --count HEAD

2. New Route in repositoryRoutes.ts

router.get(
  '/summary',
  ...repoUrlValidation(),
  handleValidationErrors,
  async (req: Request, res: Response, next: NextFunction) => {
    try {
      const { repoUrl } = req.query;
      const summary = await repositorySummaryService.getRepositorySummary(repoUrl as string);
      res.status(HTTP_STATUS.OK).json(summary);
    } catch (error) {
      next(error);
    }
  }
);

3. Shared Types in packages/shared-types/src/index.ts

export interface RepositorySummary {
  repository: {
    name: string;
    url: string;
    owner: string;
    platform: 'github' | 'gitlab' | 'bitbucket' | 'other';
  };
  created: {
    date: string; // ISO 8601
    source: CreatedDateSource;
  };
  age: {
    years: number;
    months: number;
    formatted: string; // e.g., "5.7y"
  };
  lastCommit: {
    date: string; // ISO 8601
    relativeTime: string; // e.g., "2 days ago"
    sha: string;
    author: string;
  };
  stats: {
    totalCommits: number;
    contributors: number;
    status: RepositoryStatus;
  };
  metadata: {
    cached: boolean;
    dataSource: DataSource;
    createdDateAccuracy: 'exact' | 'approximate';
    bandwidthSaved?: string;
    lastUpdated: string; // ISO 8601
  };
}

export type RepositoryStatus = 'active' | 'inactive' | 'archived' | 'empty';
export type DataSource = 'git-sparse-clone' | 'git+github-api' | 'cache';
export type CreatedDateSource = 'first-commit' | 'github-api' | 'gitlab-api';

export interface RepositoryUrlInfo {
  platform: 'github' | 'gitlab' | 'bitbucket' | 'other';
  owner: string;
  name: string;
  fullUrl: string;
}

4. Status Determination Logic

function determineRepositoryStatus(lastCommitDate: Date): RepositoryStatus {
  const daysSinceLastCommit = differenceInDays(new Date(), lastCommitDate);
  
  if (daysSinceLastCommit <= 30) return 'active';
  if (daysSinceLastCommit <= 180) return 'inactive';
  return 'archived';
}

Status Rules:

• active: Last commit within 30 days
• inactive: Last commit between 30-180 days
• archived: No commit in 180+ days
• empty: 0 commits

5. Caching Implementation

async function getRepositorySummary(repoUrl: string): Promise<RepositorySummary> {
  const cacheKey = `repo:summary:${crypto.createHash('md5').update(repoUrl).digest('hex')}`;
  
  // Try cache first (24h TTL)
  const cached = await repositoryCache.get(cacheKey);
  if (cached) {
    return { ...cached, metadata: { ...cached.metadata, cached: true } };
  }
  
  // Perform sparse clone for metadata extraction
  const tempDir = await performSparseCloneForSummary(repoUrl);
  
  try {
    const summary = await buildSummaryFromSparseClone(tempDir, repoUrl);
    
    // Cache for 24 hours
    await repositoryCache.set(cacheKey, summary, 86400);
    
    return summary;
  } finally {
    await cleanupSparseClone(tempDir);
  }
}

🧪 Testing Requirements

Unit Tests

Location: apps/backend/__tests__/unit/services/repositorySummaryService.unit.test.ts

Test Cases:

• performSparseCloneForSummary() - creates temp dir with sparse clone
• parseRepositoryUrl() - GitHub HTTPS, SSH, GitLab, Bitbucket
• getFirstCommitDate() - with sparse clone repository
• getLastCommitInfo() - parse date, sha, author correctly
• getContributorCount() - count unique authors from sparse clone
• calculateRepositoryAge() - various date ranges
• determineRepositoryStatus() - active/inactive/archived/empty
• cleanupSparseClone() - removes temp directory
• Cache hit/miss scenarios
• Error handling (empty repo, corrupted repo, cleanup on error)

Integration Tests

Location: apps/backend/__tests__/unit/routes/repositoryRoutes.unit.test.ts

Test Cases:

• GET /api/repositories/summary?repoUrl=... returns 200 OK
• Response matches expected schema
• Bandwidth usage is minimal (verify sparse clone used)
• Temp directories cleaned up after request
• Invalid URL returns 400 Bad Request
• Caching works (second request faster)
• Error handling (network timeout, invalid repo)

Manual Test Repositories

# Small repo (fast test)
https://github.com/octocat/Hello-World.git

# Medium repo (verify sparse clone efficiency)
https://github.com/facebook/react.git

# Large repo (stress test)
https://github.com/torvalds/linux.git

# GitLab repo
https://gitlab.com/gitlab-org/gitlab.git

Coverage Target

• ≥ 80% code coverage (per AGENTS.md)
• All edge cases covered
• All error paths tested
• Cleanup logic tested

📊 Performance Considerations

Optimization Strategies

1. Sparse Clone (95-99% bandwidth reduction)

   • --filter=blob:none excludes all file contents
   • --depth=1 fetches only latest commit
   • --single-branch fetches only main branch
   • Based on proven fileAnalysisService pattern

2. Efficient Git Commands

   • --max-count=1 for first/last commit (O(1))
   • --count flag for commit counting (O(1))
   • shortlog -s is optimized by Git
   • All commands work on sparse clone

3. Aggressive Caching

   • 24-hour TTL (Git data rarely changes)
   • Hash-based cache keys
   • Multi-tier cache (Redis → Disk → Memory)

4. Resource Cleanup

   • Temp directories cleaned immediately after use
   • Try-finally blocks ensure cleanup on error
   • No resource leaks

Expected Performance

• First request (sparse clone): 0.5-2 seconds (vs 5-30s for full clone)
• Bandwidth: 1-5 MB (vs 100-500 MB for full clone)
• Cached request: <50ms (cache lookup)
• Large repos (100k commits): Same speed (sparse clone is size-independent for metadata)

Comparison: Full Clone vs Sparse Clone

Metric	Full Clone	Sparse Clone	Improvement
Bandwidth	100-500 MB	1-5 MB	95-99%
Time	5-30 seconds	0.5-2 seconds	75-90%
Disk Usage	100-500 MB	1-5 MB	95-99%
Metadata Accuracy	100%	100%	Same

✔️ Definition of Done

• All stats from mockup are returned (name, owner, created, age, commits, contributors, status)
• Sparse clone implementation (not full clone)
• Bandwidth usage verified (should be <5MB for most repos)
• Temp directory cleanup verified (no leaks)
• URL parsing works for GitHub, GitLab, Bitbucket, self-hosted
• First commit date used as "created" date
• Last commit info extracted correctly
• Contributor count accurate
• Status determination logic works
• 24-hour caching implemented
• Unit tests pass with ≥80% coverage
• Integration tests pass
• No regression in existing tests
• Linting passes (pnpm lint)
• Build succeeds (pnpm build)
• Frontend can successfully consume the endpoint
• API documented in README.md
• PR reviewed and approved

📝 Implementation Notes

Why Sparse Clone?

The codebase already uses sparse cloning in fileAnalysisService.ts for file analysis:

• Proven in production - battle-tested pattern
• 95-99% bandwidth reduction - excludes all file contents
• Metadata extraction - Git commands work perfectly on sparse clones
• No full clone needed - tree structure + commit history is sufficient

Why First Commit ≈ Created Date?

In practice, first commit date is functionally equivalent to repository creation date:

• Most repos have first commit within hours of creation
• Users can't distinguish the difference in the UI
• Avoids rate limiting entirely
• Works universally across all Git platforms

Alternative Approaches Considered

❌ Full Clone: Wastes 95-99% bandwidth downloading file contents we don't need
❌ GitHub API Primary: Rate limiting kills multi-user deployments
❌ Scraping: Fragile, violates ToS, slower than Git
✅ Sparse Clone + Git-First: Fast, scalable, reliable, minimal bandwidth

Estimated Effort: Medium (8-12 hours)
Priority: High (blocks frontend redesign completion)
Complexity: Medium
Risk: Low (reuses existing sparse clone infrastructure)

Drafting phased implementation plan (will keep this comment updated through delivery).

Phase 1 – Discovery & Design (now)

• Objectives: confirm scope, finalize API contract/validation, decide status logic, cache/TTL strategy, sparsity pattern reuse, edge cases, and test plan.
• Deliverables: design notes, API schema (request/response), status rules, cache key/TTL, git command plan, validation rules, risks + mitigations, test matrix.

Phase 2 – Backend Service Implementation

• Tasks: add shared types (RepositorySummary, status/data source enums), implement repositorySummaryService (sparse clone, git queries, status calc, age calc, contributor/commit counts, cleanup), error mapping, logging hooks.
• Dependencies: Phase 1 design decisions; existing repositoryCache, repositoryCoordinator, sparse clone pattern from fileAnalysisService.
• Complexity: Medium.
• Deliverables: service module code + unit tests.

Phase 3 – API Wiring & Integration

• Tasks: expose GET /api/repositories/summary route with validation + rate limiting, hook service + cache, wire metrics/logging, schema validation, HTTP error handling.
• Dependencies: Phase 2 service, shared types built.
• Complexity: Medium.
• Deliverables: route/controller, integration tests, updated health/metrics where relevant.

Phase 4 – Testing & Hardening

• Tasks: expand test coverage (edge cases, empty repo, large repo, invalid URLs, timeouts), perf checks on sparse clone path, cache behavior verification, cleanup verification, lint/typecheck.
• Dependencies: Phases 2–3.
• Complexity: Medium.
• Deliverables: test results, coverage, perf notes, fixes.

Phase 5 – Finalization & Handover

• Tasks: docs (API usage, caching, status rules), changelog/README updates, ensure frontend consumers informed, PR summary/rollout.
• Dependencies: prior phases complete.
• Complexity: Low.
• Deliverables: documentation updates, PR summary.

Starting Phase 1 now; this comment will be updated with progress and next steps as we move through phases.

✅ Refined Phase 1 – Discovery & Design (COMPLETED)

Status: Complete - All design artifacts produced

Key Findings

• Service Already Exists: apps/backend/src/services/repositorySummaryService.ts (429 lines) fully implemented with Git-first sparse clone approach
• Missing Types: 5 type definitions needed in @gitray/shared-types (now added)
• Missing Route: No API endpoint exposed yet (now created)
• Missing Tests: No test coverage (now added - 12/12 passing ✅)

API Contract

• Endpoint: GET /api/repositories/summary
• Query Parameter: repoUrl (string, required, URL-validated)
• Validation: Existing isSecureGitUrl + SSRF protection
• Response: RepositorySummary interface with full metadata
• Status Codes: 200 (success), 400 (ValidationError), 500 (server errors)

Type Definitions ✅ Added

All types added to packages/shared-types/src/index.ts (lines 489-576):

• RepositoryPlatform = 'github' | 'gitlab' | 'bitbucket' | 'other'
• RepositoryStatus = 'active' | 'inactive' | 'archived' | 'empty'
• CreatedDateSource = 'first-commit' | 'git-api' | 'platform-api'
• RepositoryUrlInfo interface
• RepositorySummary interface (complete with all nested fields)

Repository Status Logic

Already implemented in service (apps/backend/src/services/repositorySummaryService.ts:264-275):

• active: Last commit ≤ 30 days
• inactive: 30 < last commit ≤ 180 days
• archived: Last commit > 180 days
• empty: 0 commits

Cache Strategy

Already implemented (apps/backend/src/services/repositorySummaryService.ts:25,388-425):

• Cache Key: repo:summary:${md5(repoUrl)}
• TTL: 24 hours (86400 seconds)
• Storage: Redis with JSON serialization
• Coordination: Uses repositoryCoordinator.coordinatedOperation() to prevent duplicate clones

Git Operations (Sparse Clone)

Sparse clone implementation with 95-99% bandwidth reduction:

git init
git remote add origin <repoUrl>
git config core.sparseCheckout true
git fetch --filter=blob:none --depth=1 --single-branch --no-tags origin HEAD
git checkout FETCH_HEAD
git rev-list --count HEAD                    # Total commits
git log --reverse --format=%aI --max-count=1 # First commit
git log -1 --format=%aI|%H|%an               # Last commit
git shortlog -s -n --all                      # Contributors

Error Taxonomy

Uses existing error classes from packages/shared-types/src/index.ts:

• ValidationError → HTTP 400 (invalid/unsafe URLs)
• RepositoryError → HTTP 500 (clone failures, handled gracefully for empty repos)
• GitrayError → HTTP 500 (general service errors)

Edge Cases ✅ Handled

1. Empty repositories (0 commits) → status='empty'
2. Single commit repos → age calculation handles correctly
3. Network timeouts → cleanup in finally block
4. Corrupted repos → Git errors caught and logged
5. Very large repos → sparse clone handles efficiently
6. SSH vs HTTPS URLs → both parsed correctly
7. Cleanup on error → try-finally ensures temp dir removal

Test Matrix ✅ Implemented

Unit Tests (apps/backend/__tests__/unit/services/repositorySummaryService.unit.test.ts):

• ✅ 12/12 tests passing
• URL parsing (GitHub HTTPS, SSH, GitLab, Bitbucket)
• Status logic (active/inactive/archived/empty)
• Empty repo handling
• Cache hit/miss scenarios
• Cleanup verification

• ✅ 10/10 tests passing
• 200 OK response
• 400 validation errors
• Cache behavior
• Metrics recording
