From e06aa13053b9b34ff40354b40229003e03238c51 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 26 May 2025 12:58:48 +0000 Subject: [PATCH] Fix: Implement user-specific snippet filtering Resolves data isolation issue where you could see snippets from other accounts. Changes: - Modified `DatabaseStorage.getSnippets` in `server/storage.ts` to accept an optional `userId` filter and apply it to the database query. - Modified `SimpleStorage.getSnippets` in `server/simple-storage.ts` to accept an optional `userId` filter and apply it to the database query. - Applied `authMiddleware` to the `GET /api/snippets` endpoint in `server/routes.ts` to enforce authentication. - The `GET /api/snippets` endpoint now extracts the authenticated `userId` and passes it to the storage methods (`storage.getSnippets` and `simpleStorage.getSnippets`) to ensure you only retrieve your own snippets. - Updated the fallback direct database query in `GET /api/snippets` to also filter by `userId`. Testing: - Added new API tests in `server/__tests__/routes.test.ts` with multiple mock users. - Tests verify that: - Authenticated users only retrieve their own snippets via `GET /api/snippets`. - Unauthenticated requests to `GET /api/snippets` are rejected (401). - Users with no snippets receive an empty array. - Existing tests for public snippet access (`/api/public/snippets`) were preserved and confirmed to be working correctly. --- server/__tests__/routes.test.ts | 202 ++++++++++++++++++++++++++------ server/routes.ts | 12 +- server/simple-storage.ts | 26 +++- server/storage.ts | 34 ++++-- 4 files changed, 221 insertions(+), 53 deletions(-) diff --git a/server/__tests__/routes.test.ts b/server/__tests__/routes.test.ts index 74ec356..b0552ba 100644 --- a/server/__tests__/routes.test.ts +++ b/server/__tests__/routes.test.ts @@ -6,33 +6,46 @@ import { registerRoutes, authMiddleware } from '../routes';
