📝 Walkthrough

Walkthrough

This PR resolves TypeScript build errors stemming from unresolved merge conflicts in the backend codebase. It repairs Express route handler syntax across multiple endpoints, adds comprehensive test coverage for stream creation with validation flows, and fixes a structural break in the progress calculation service function that left code outside its intended scope.

Changes

Backend Build Error Fixes

Layer / File(s) Summary
Express route handler syntax repairs
backend/src/index.ts
Five route handler closures are corrected by removing duplicate/malformed closing braces (}); and },); patterns) at paginated /api/streams responses, filtered stream list endpoints, /api/streams/:id/start-time PATCH handler, and /api/streams/:id DELETE handler, restoring valid TypeScript syntax across the routing layer.
POST /api/streams test coverage
backend/src/index.test.ts
Test suite extends with setup/mocks for POST stream creation, success assertions verifying computed progress and history retrieval, and validation test cases covering missing sender, duration below minimum, unsupported asset code, and non-positive amounts, including correct section boundaries for subsequent test blocks.
calculateProgress function structure repair
backend/src/services/streamStore.ts
Function body closure is repositioned so vesting/progress computation (effectiveAt, elapsed-based vesting, return object fields) and variable definitions (elapsed, vestedAmount, ratio) remain within the function scope instead of orphaned outside, restoring coherent control flow.

Possibly related PRs

  • ritik4ever/stellar-stream#191: Both PRs modify the pause/resume feature plumbing—particularly backend/src/services/streamStore.ts (calculateProgress logic for paused vesting) and associated Express routing in backend/src/index.ts.
  • ritik4ever/stellar-stream#275: The main PR's change to calculateProgress function structure directly aligns with newly added calculateProgress unit tests in backend/src/services/streamStore.progress.test.ts.
  • ritik4ever/stellar-stream#481: Both PRs touch backend/src/services/streamStore.ts vesting/progress logic, making stream-progress computation changes directly related.

950-968: ⚠️ Potential issue | 🔴 Critical | 🏗️ Heavy lift

PATCH /api/streams/:id/start-time handler is non-functional.

The handler is truncated after extracting the user (line 966). It's missing:

  1. Request body validation using updateStreamStartAtSchema.safeParse(req.body)
  2. Authorization check that user.accountId === existingStream.sender
  3. The actual call to updateStreamStartAt(parsedId.value, newStartAt)
  4. Any response to the client

This endpoint will accept requests but perform no action and never respond, causing client timeouts.

🐛 Proposed fix to restore handler functionality
     const user = (req as any).user;
 
+    if (existingStream.sender !== user.accountId) {
+      sendApiError(req, res, 403, "Only the sender can update the start time.", {
+        code: "FORBIDDEN",
+      });
+      return;
+    }
+
+    const parsedBody = updateStreamStartAtSchema.safeParse(req.body);
+    if (!parsedBody.success) {
+      sendValidationError(req, res, parsedBody.error.issues);
+      return;
+    }
+
+    try {
+      const updated = updateStreamStartAt(parsedId.value, parsedBody.data.startAt);
+      res.json({
+        data: {
+          ...updated,
+          progress: calculateProgress(updated),
+        },
+      });
+    } catch (error: any) {
+      console.error("Failed to update stream start time:", error);
+      const normalizedError = normalizeUnknownApiError(
+        error,
+        "Failed to update stream start time.",
+      );
+      sendApiError(
+        req,
+        res,
+        normalizedError.statusCode,
+        normalizedError.message,
+        {
+          code: normalizedError.code ?? "INTERNAL_ERROR",
+        },
+      );
+    }

346-418: ⚠️ Potential issue | 🔴 Critical

Fix missing /api/streams route wrapper in backend/src/index.ts

  • The streams query/pagination code (listStreamsQuerySchema.safeParse(req.query), sendValidationError(req, res, ...), res.json(...)) appears immediately after app.get("/api/assets" ...) and is not inside any app.get("/api/streams"... handler (no /api/streams registration exists).
  • This will cause TypeScript errors (req/res not defined) and likely indicates missing/incorrect braces around the intended GET /api/streams route.

module scope after an existing "});" that causes TS1128; open
backend/src/index.ts, locate the block that ends with "});" (the same block
referenced around the end of the file) and remove the extra "})" token so the
file ends with the single correct "});" closure; ensure no other unmatched
braces/parentheses remain and run tsc to verify the syntax error is resolved.

… clean version and adding admin DELETE endpoint

The commit 8ae938a introduced 16 TS errors by:
- Removing needed imports (getStreamEventSummary, webhookRegistrationSchema)
- Adding a non-existent 'paused' status to StreamStatus array
- Leaving incomplete merge artifacts

Fix: restore index.ts from clean commit 51e81f3 and cherry-pick
only the functional DELETE /api/streams/:id endpoint with proper imports.

Verified: tsc --noEmit passes with 0 errors on index.ts

📊 CI Status — Pre-existing Failures Only

The CI failures on this PR are not caused by our changes. Backend CI runs npx vitest run --coverage which fails because the main branch has 41 pre-existing test failures.

This PR only fixes TypeScript compilation (issue #520). tsc --noEmit passes with 0 errors.

See PR #537 for a comprehensive fix of the test suite.
