📌 Issue Overview

Landing Page Repository Input Not Connected to CodeGraph Indexing

The landing page allows users to enter a GitHub repository URL, but clicking "Analyze Repository" fails because the frontend calls a non-existent backend API endpoint (/api/repo-stats). The repository indexing functionality with FalkorDB exists in the codebase but is not exposed via the REST API for the web frontend.

---

🔍 Steps to Reproduce

1. Go to the landing page (LandingPage.tsx)
2. Enter a valid GitHub repository URL (e.g., https://github.com/AOSSIE-Org/Devr.AI)
3. Click on "Analyze Repository" button
4. See the error toast: "Failed to fetch repository stats. Please check the URL or backend server."

---

🎯 Expected Behavior

1. User enters a GitHub repository URL in the landing page
2. Frontend sends the URL to backend API endpoint
3. Backend calls RepoService.index_repo() to index the repository using FalkorDB CodeGraph
4. Repository is cloned, analyzed, and stored as a graph in FalkorDB
5. Indexing metadata (status, node count, edge count) is saved to Supabase
6. User receives success message with repository stats
7. User is navigated to the dashboard showing the indexed repository data

---

🚨 Actual Behavior

1. User enters a GitHub repository URL in the landing page
2. Frontend attempts to POST to http://localhost:8000/api/repo-stats (line 23 in LandingPage.tsx)
3. Request fails with 404 - endpoint does not exist in the backend
4. User sees error toast message
5. No repository indexing occurs
6. User cannot proceed to dashboard

Technical Details:

The frontend makes this call:

const response = await axios.post('http://localhost:8000/api/repo-stats', { repo_url: repoUrl });

But /api/repo-stats endpoint is not defined in:

• ❌ backend/app/api/router.py
• ❌ backend/app/api/v1/ (no repositories endpoint)

However, the infrastructure exists:

• ✅ backend/app/services/codegraph/repo_service.py - Complete RepoService class
• ✅ RepoService.index_repo() method works (tested via Discord bot)
• ✅ FalkorDB integration functional
• ✅ Supabase database with indexed_repositories table
• ❌ Just missing the REST API layer to expose this functionality

---

Files to Modify:

• backend/app/api/v1/repositories.py (create new file)
• backend/app/api/router.py (add router registration)
• frontend/src/components/landing/LandingPage.tsx (update API endpoint)

Later on we can extend this functionality to provide the repository stats too including with the functionality to index repositories.

@smokeyScraper Interested in taking this up. Assign me if available

Hi @smokeyScraper,
I'd like to pick up Issue #170.My proposed approach is to:

1. Create a new POST /api/v1/repositories/index endpoint to handle the repo_url.
2. Have this endpoint validate the URL, enqueue the RepoService.index_repo() job, and persist the metadata in Supabase.
3. Update LandingPage.tsx to call this new API and show success/error feedback to the user.
   Please assign this to me if it sound okay to you!

Assigning to @Vaibhaviitian. Sorry @Bhup-GitHUB, @OmRatnaparkhe, but this issue was proposed by @Vaibhaviitian himself, that's why assigning it to him.
