Phase 2: Authentication Module

Implement OAuth-based authentication with NodeSource Accounts API, including token storage, validation, and the auth manager orchestrator.

Tasks

Task 5: Implement token storage module — Create token-storage.ts to read/write credentials to ~/.agents/.nodesource-auth.json. Implement secure file permissions (0600). Handle missing file, invalid JSON, and expired tokens. Note: on Windows, chmod 0600 has minimal effect; credential protection relies on directory ACLs.
- Depends on: Task 4
- Files: packages/core/src/auth/token-storage.ts
- Testing: Unit tests for save/load credentials. Test file permissions. Test handling of corrupted file.
Task 6: Implement token validator module — Create token-validator.ts to validate service tokens with Accounts API at /accounts/org/access-token. Handle network errors, 401/403 responses, and timeouts. Return validation result with permissions list.
- Depends on: Task 5
- Files: packages/core/src/auth/token-validator.ts
- Testing: Unit tests with mocked HTTP responses. Test success, 401, 500, and timeout scenarios.
Task 7: Implement OAuth callback server — Create oauth-server.ts to start local HTTP server on port 8765 (with fallback to 8766-8770). Listen for OAuth callback with token and orgId. Implement 5-minute timeout. Return received credentials.
- Depends on: Task 4
- Files: packages/core/src/auth/oauth-server.ts
- Testing: Unit tests for server startup, callback handling, timeout, and port conflicts.
Task 8: Implement auth manager orchestrator — Create auth-manager.ts with ensureAuthenticated() function. Check for existing valid credentials first. If missing/expired, initiate OAuth flow (open browser, start callback server). Validate token with Accounts API. Store credentials. Return Credentials object.
- Depends on: Tasks 5, 6, 7
- Files: packages/core/src/auth/auth-manager.ts, packages/core/src/auth/index.ts
- Testing: Integration test with mocked dependencies. Test happy path, existing valid creds, expired creds, OAuth timeout.
