Add stats API by introducing v1 GET /api/v1/stats/by-period and /api/v1/stats/response-time endpoints and wiring controllers, validation, and OpenAPI registration

Add v1 stats endpoints with controllers that compute period-based email counts and response-time metrics, move query validation to dedicated zod modules, and update UI components to consume new response/query types.

📍Where to Start

Start with the v1 route handlers: GET /api/v1/stats/by-period in apps/web/app/api/v1/stats/by-period/route.ts and GET /api/v1/stats/response-time in apps/web/app/api/v1/stats/response-time/route.ts; then review their controllers in apps/web/app/api/user/stats/by-period/controller.ts and apps/web/app/api/user/stats/response-time/controller.ts.

  • line 37: MainStatChart parses startOfPeriod using parse(item.startOfPeriod, "MMM dd, yyyy", new Date()) (line 37), but getStatsByPeriod formats startOfPeriod as format(stat.startOfPeriod, "LLL dd, y"). The tokens LLL vs MMM and y vs yyyy are not guaranteed to be interchangeable across locales in date-fns. This mismatch can cause parse to return an invalid date, and the subsequent format(date, "yyyy-MM-dd") on line 38 will throw at runtime. Ensure the parse format exactly matches the format used to produce the string (or pass a machine-parseable value like ISO date). [ Low confidence ]

  • line 6: fromDate is defined as z.coerce.number().nullish() which accepts Infinity and -Infinity by default in Zod. These values will pass validation and reach new Date(fromDate) in the controller, producing an Invalid Date that is then sent to Prisma, likely causing a runtime error during SQL parameter serialization. Add .finite() to reject non-finite numbers. [ Already posted ]
  • line 6: fromDate permits any finite number, including values outside the valid JS Date range (approximately ±8.64e15 ms). Extremely large/small finite values will pass validation, but new Date(fromDate) yields an Invalid Date, leading to runtime errors when used as a SQL parameter. Add range constraints (e.g., .min(-8640000000000000).max(8640000000000000)) or validate resulting Date validity. [ Already posted ]
  • line 7: toDate has the same issues as fromDate: it allows Infinity/-Infinity (no .finite()) and any out-of-range finite number, both of which lead to new Date(toDate) producing Invalid Date and runtime failures during SQL parameterization. Mirror the same .finite() and range constraints on toDate. [ Already posted ]
apps/web/app/api/user/stats/response-time/validation.ts — 0 comments posted, 3 evaluated, 3 filtered
  • line 4: z.coerce.number() will accept the string values 'Infinity'/'-Infinity' (and numeric Infinity/-Infinity) as valid numbers. Because .finite() is not applied, fromDate and toDate can be Infinity/-Infinity, which are nonsensical for dates/timestamps and likely to break downstream logic that expects real numeric timestamps. [ Already posted ]
  • line 4: z.coerce.number() will coerce many non-numeric query values into numbers without error: e.g., an empty string "" or " " becomes 0, and true/false become 1/0. This means inputs like ?fromDate= or ?fromDate=true are silently accepted as 0/1, which is likely unintended for date/timestamp filters and can cause incorrect range queries. [ Already posted ]
  • line 5: The same issues described for fromDate also apply to toDate because it uses the same z.coerce.number().nullish() pipeline, so toDate can also be Infinity/-Infinity or silently accept empty/boolean values as 0/1. [ Already posted ]
apps/web/app/api/v1/stats/by-period/route.ts — 0 comments posted, 2 evaluated, 2 filtered
  • line 9: validateApiKeyAndGetEmailProvider(request) creates an email provider and enforces presence/refresh of access tokens, but the endpoint only needs the user/account identity to compute DB stats. This introduces unnecessary side effects and failure modes (e.g., missing/expired tokens) causing 401/other errors even though the stats query doesn’t require provider access. Use validateApiKey to authenticate without creating the provider, or defer provider creation until needed. [ Low confidence ]
  • line 28: accountId obtained from validateApiKeyAndGetEmailProvider (which returns the user OAuth account's id) is passed into getEmailAccountId({ accountId }) which looks up prisma.emailAccount.findUnique({ where: { accountId, userId } }). Unless the OAuth Account id is guaranteed to equal EmailAccount.accountId (an external provider ID) this lookup will fail and return undefined, causing a 400 "Email account not found" even for valid API keys. Fix by passing the correct external account identifier that emailAccount.accountId expects (or change getEmailAccountId to accept the current value), or pass email explicitly. [ Already posted ]
apps/web/app/api/v1/stats/response-time/route.ts — 0 comments posted, 2 evaluated, 2 filtered
  • line 29: Incorrect identifier passed to getEmailAccountId: the accountId provided by validateApiKeyAndGetEmailProvider is the internal account record id, but getEmailAccountId expects an external provider accountId (and queries prisma.emailAccount.findUnique({ where: { accountId, userId } })). This will typically fail to find the account, returning 400 "Email account not found" even for valid API keys. Either change the helper to support internal id in a separate parameter/path or pass the correct external accountId (or omit the param when not needed) and, for the selected account, recreate the provider as needed. [ Already posted ]
  • line 46: Email provider/account mismatch: when the email query param targets a different account than the one used to create emailProvider, the handler passes a provider tied to the first account (validateApiKeyAndGetEmailProvider) together with a different emailAccountId to getResponseTimeStats. This can compute stats from one mailbox while attributing them to another, causing incorrect results or data contamination. Fix by deriving the provider from the resolved emailAccountId (and its provider type) after line 33, or by ensuring the API key selection aligns with the requested account and recreating the provider accordingly before calling getResponseTimeStats. [ Low confidence ]

Summary by CodeRabbit

  • New Features

    • Added two stats APIs: /stats/by-period (periodized email metrics with aggregates) and /stats/response-time (response-time summary, distribution, trend). Both include request/response validation and typed responses and are registered in OpenAPI.
  • Refactor

    • Route handlers now delegate stats computation to dedicated controller modules for clearer separation.
  • Chores

    • Email-account lookup now returns the account identifier (id); docs updated.

Walkthrough

Adds two new stats controllers (by-period and response-time) with Zod validation, registers v1 OpenAPI routes, refactors user routes to delegate to controllers, updates helper to return email account IDs, and updates frontend types to use the new controller/validation exports.

Changes

Cohort / File(s) Summary
By-period controller & validation + user/v1 routes
apps/web/app/api/user/stats/by-period/controller.ts, apps/web/app/api/user/stats/by-period/validation.ts, apps/web/app/api/user/stats/by-period/route.ts, apps/web/app/api/v1/stats/by-period/route.ts, apps/web/app/api/v1/stats/by-period/validation.ts
New controller implements period-based email stats (Prisma raw SQL with DATE_TRUNC), transforms per-period rows and totals; Zod query/response schemas added; user and v1 routes validate input, resolve emailAccountId, and delegate to controller.
Response-time controller & validation + user/v1 routes
apps/web/app/api/user/stats/response-time/controller.ts, apps/web/app/api/user/stats/response-time/validation.ts, apps/web/app/api/user/stats/response-time/route.ts, apps/web/app/api/v1/stats/response-time/route.ts, apps/web/app/api/v1/stats/response-time/validation.ts
New controller computes response-time stats: fetches recent sent message IDs from provider, loads cached DB entries, computes uncached response times, persists new results (skip duplicates), combines and filters entries, and returns summary, distribution, and trend; routes delegate and validate.
OpenAPI integration
apps/web/app/api/v1/openapi/route.ts
Registers new OpenAPI paths: GET /stats/by-period and GET /stats/response-time with query and response schemas and API key security.
Helper behavior change
apps/web/app/api/v1/helpers.ts
When resolving by email or accountId now returns the email account id (cuid) instead of the email address; docs updated.
Frontend type updates
apps/web/app/(app)/[emailAccountId]/stats/MainStatChart.tsx, apps/web/app/(app)/[emailAccountId]/stats/ResponseTimeAnalytics.tsx, apps/web/app/(app)/[emailAccountId]/stats/StatsSummary.tsx
Updated imports and props/types to use new controller/validation types (StatsByPeriodResponse, ResponseTimeResponse/Query/StatsByPeriodQuery) instead of prior route-exported types.
Auxiliary files
apps/web/package.json, version.txt
Downgraded @asteasolutions/zod-to-openapi from 8.1.07.3.4; bumped version.txt v2.21.61 → v2.21.62.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Pay special attention to:
    • Prisma raw SQL typing/parameterization and DATE_TRUNC usage in by-period/controller.ts.
    • Caching logic, duplicate-skipping persistence, and correctness of calculateResponseTimes in response-time/controller.ts.
    • Consistency between Zod schemas, controller inputs/outputs, and OpenAPI registrations (apps/.../v1/openapi/route.ts).
    • Frontend type updates referencing new controller/validation exports (MainStatChart.tsx, ResponseTimeAnalytics.tsx, StatsSummary.tsx).

Poem

🐰 I hopped through rows of dates and counts today,
I chased late replies and watched the carrots sway.
I stacked the periods, counted every thread,
Cached a few answers, tucked the rest to bed.
SQL crumbs and trend-lined hops — I’m happy, carrot-fed. 🥕

23-30: Validate date values before constructing Date objects.

The truthy check for fromDate/toDate will ignore epoch 0 (unlikely to matter in practice), but more importantly, invalid numeric values like Infinity or out-of-range timestamps will produce Invalid Date objects passed to SQL.

   // Build date conditions without starting with AND
   const dateConditions: Prisma.Sql[] = [];
-  if (fromDate) {
-    dateConditions.push(Prisma.sql`date >= ${new Date(fromDate)}`);
+  if (fromDate != null) {
+    const date = new Date(fromDate);
+    if (!Number.isNaN(date.getTime())) {
+      dateConditions.push(Prisma.sql`date >= ${date}`);
+    }
   }
-  if (toDate) {
-    dateConditions.push(Prisma.sql`date <= ${new Date(toDate)}`);
+  if (toDate != null) {
+    const date = new Date(toDate);
+    if (!Number.isNaN(date.getTime())) {

🧹 Nitpick comments (3)
apps/web/app/api/user/stats/by-period/route.ts (1)

5-7: Missing exported response type for client-side type safety.

Per coding guidelines, GET routes should export response types using the Get[Feature]Response pattern. Consider adding:

 // Re-export types for backwards compatibility
 export type { StatsByPeriodQuery as StatsByWeekParams } from "./controller";
 export type { StatsByPeriodResponse as StatsByWeekResponse } from "./controller";
+
+// Export response type for client consumption
+export type GetStatsByPeriodResponse = StatsByPeriodResponse;

Based on learnings, API routes should export response types as Get[Feature]Response for type-safe client consumption.

8-12: Consider using .optional() instead of .nullish() for consistency with v1 validation.

The v1 validation schema at apps/web/app/api/v1/stats/by-period/validation.ts uses .optional() while this controller uses .nullish(). This creates subtle behavioral differences - .nullish() accepts both null and undefined, while .optional() only accepts undefined.

 export const statsByPeriodQuerySchema = z.object({
   period: zodPeriod,
-  fromDate: z.coerce.number().nullish(),
-  toDate: z.coerce.number().nullish(),
+  fromDate: z.coerce.number().optional(),
+  toDate: z.coerce.number().optional(),
 });
apps/web/app/api/v1/stats/response-time/route.ts (1)

9-9: Consider using .with() for request-scoped context.

Per coding guidelines, use .with() method to attach context variables within specific functions rather than using a global logger. For request-scoped logging with request identifiers, consider creating the logger inside the handler.

-const logger = createScopedLogger("api/v1/stats/response-time");
+const baseLogger = createScopedLogger("api/v1/stats/response-time");

 export const GET = withError(async (request) => {
+  const logger = baseLogger.with({ /* request context if needed */ });

Based on learnings, using .with() to attach context within functions is preferred over global loggers.

apps/web/app/api/**/*.{ts,tsx}: API routes must use withAuth, withEmailAccount, or withError middleware for authentication
All database queries must include user scoping with emailAccountId or userId filtering in WHERE clauses
Request parameters must be validated before use; avoid direct parameter usage without type checking
Use generic error messages instead of revealing internal details; throw SafeError instead of exposing user IDs, resource IDs, or system information
API routes should only return necessary fields using select in database queries to prevent unintended information disclosure
Cron endpoints must use hasCronSecret or hasPostCronSecret to validate cron requests and prevent unauthorized access
Request bodies should use Zod schemas for validation to ensure type safety and prevent injection attacks

**/app/api/**/*.ts: ALL API routes that handle user data MUST use appropriate middleware: use withEmailAccount for email-scoped operations, use withAuth for user-scoped operations, or use withError with proper validation for public/custom auth endpoints
Use withEmailAccount middleware for operations scoped to a specific email account, including reading/writing emails, rules, schedules, or any operation using emailAccountId
Use withAuth middleware for user-level operations such as user settings, API keys, and referrals that use only userId
Use withError middleware only for public endpoints, custom authentication logic, or cron endpoints. For cron endpoints, MUST use hasCronSecret() or hasPostCronSecret() validation
Cron endpoints without proper authentication can be triggered by anyone. CRITICAL: All cron endpoints MUST validate cron secret using hasCronSecret(request) or hasPostCronSecret(request) and capture unauthorized attempts with captureException()
Always validate request bodies using Zod schemas to ensure type safety and prevent invalid data from reaching database operations
Maintain consistent error response format across all API routes to avoid information disclosure while providing meaningful error feedback

**/*.ts: ALL database queries MUST be scoped to the authenticated user/account by including user/account filtering in WHERE clauses to prevent unauthorized data access
Always validate that resources belong to the authenticated user before performing operations, using ownership checks in WHERE clauses or relationships
Always validate all input parameters for type, format, and length before using them in database queries
Use SafeError for error responses to prevent information disclosure. Generic error messages should not reveal internal IDs, logic, or resource ownership details
Only return necessary fields in API responses using Prisma's select option. Never expose sensitive data such as password hashes, private keys, or system flags
Prevent Insecure Direct Object References (IDOR) by validating resource ownership before operations. All findUnique/findFirst calls MUST include ownership filters
Prevent mass assignment vulnerabilities by explicitly whitelisting allowed fields in update operations instead of accepting all user-provided data
Prevent privilege escalation by never allowing users to modify system fields, ownership fields, or admin-only attributes through user input
All findMany queries MUST be scoped to the user's data by including appropriate WHERE filters to prevent returning data from other users
Use Prisma relationships for access control by leveraging nested where clauses (e.g., emailAccount: { id: emailAccountId }) to validate ownership

apps/web/app/api/user/stats/by-period/route.ts (1)

9-27: LGTM!

The route handler correctly uses withEmailAccount middleware, validates query parameters with the Zod schema, and delegates to the controller. The allowOrgAdmins option is appropriately configured.

apps/web/app/api/user/stats/by-period/controller.ts (2)

50-64: Raw SQL usage is safe due to Zod enum validation.

The period value is interpolated using Prisma.raw(), but this is safe because zodPeriod constrains it to the enum ["day", "week", "month", "year"]. The emailAccountId is properly parameterized. The query structure is sound.


67-103: LGTM!

The getStatsByPeriod function correctly transforms raw SQL results to the expected format, handles bigint-to-number conversion for JSON compatibility, and uses lodash's specific import pattern as per coding guidelines.

apps/web/app/api/v1/stats/by-period/route.ts (1)

8-47: LGTM!

The v1 route correctly implements API key authentication via validateApiKeyAndGetEmailProvider, validates query parameters with safeParse, handles errors gracefully, and delegates to the shared controller. The use of withError middleware is appropriate for API-key authenticated endpoints.

apps/web/app/api/v1/stats/response-time/route.ts (1)

11-50: LGTM!

The route handler correctly validates API key authentication, parses query parameters, resolves the email account, and delegates to the controller with all required parameters including emailProvider and logger.

apps/web/app/api/v1/stats/by-period/validation.ts (1)

1-29: LGTM!

The validation schemas are well-structured with proper Zod definitions. The response schema correctly captures the expected output shape, and the inferred type export follows project conventions.

apps/web/app/api/v1/openapi/route.ts (1)

59-99: LGTM!

The new OpenAPI path registrations are well-structured with appropriate descriptions, security schemes, query schemas, and response schemas. This provides good API documentation for consumers.

apps/web/app/api/v1/stats/response-time/validation.ts (1)

1-41: LGTM!

The validation schemas comprehensively define the request query parameters and the full response structure including summary statistics, distribution buckets, and trend data. The type export follows project conventions.

apps/web/app/api/user/stats/response-time/route.ts (2)

5-7: Missing exported response type for client-side type safety.

Similar to the by-period route, consider adding a GetResponseTimeResponse export alias for client consumption:

 // Re-export types for backwards compatibility
 export type { ResponseTimeQuery as ResponseTimeParams } from "./controller";
 export type { ResponseTimeResponse as GetResponseTimeResponse } from "./controller";

The current re-export as GetResponseTimeResponse already follows the naming convention, which is good. This comment is just confirmation that the pattern is correct.


9-24: LGTM!

The route correctly uses withEmailProvider middleware which provides the email provider, authentication context, and scoped logger. Query parameters are validated and the controller is invoked with all required dependencies.

apps/web/app/api/user/stats/response-time/controller.ts (2)

64-114: Excellent caching strategy!

The implementation efficiently caches response-time calculations and only computes uncached messages. Database queries are properly scoped with emailAccountId, and skipDuplicates: true prevents race conditions.


149-196: Helper functions look good!

calculateTrend properly groups response times by week, calculates medians, and sorts chronologically. getEmptyStats provides a consistent empty response structure. Both implementations are correct.

⚠️ Potential issue | 🟠 Major

Validate that coerced date values produce valid Date objects.

The schema coerces values to numbers but doesn't validate that they're finite or within valid timestamp ranges. Values like Infinity, NaN, or extremely large numbers will pass validation but produce Invalid Date objects when passed to new Date() at lines 54-55.

Apply this diff to add validation:

 export const responseTimeQuerySchema = z.object({
-  fromDate: z.coerce.number().nullish(),
-  toDate: z.coerce.number().nullish(),
+  fromDate: z.coerce
+    .number()
+    .finite()
+    .refine((val) => val === null || val === undefined || !isNaN(new Date(val).getTime()), {

+    })
+    .nullish(),
+  toDate: z.coerce
+    .number()

⚠️ Potential issue | 🔴 Critical

Fix truthy checks and validate Date construction to prevent dropping valid timestamps and Invalid Date errors.

Two critical issues:

  1. Truthy checks drop valid epoch timestamp: Using fromDate ? at lines 54-55 treats 0 (Unix epoch, Jan 1 1970) as falsy and skips it, even though it's a valid timestamp.

  2. No validation of Date construction: Directly calling new Date(fromDate) without checking if the result is valid can pass Invalid Date objects to emailProvider.getSentMessageIds, potentially causing downstream errors.

Based on learnings, use explicit null/undefined checks instead of truthy checks, and validate Date objects before use.

Apply this diff:

   // 1. Fetch sent message IDs (lightweight - just id and threadId)
+  const afterDate = fromDate !== null && fromDate !== undefined ? new Date(fromDate) : undefined;
+  const beforeDate = toDate !== null && toDate !== undefined ? new Date(toDate) : undefined;
+
+  if (afterDate && isNaN(afterDate.getTime())) {
+    throw new Error("Invalid fromDate timestamp");
+  }
+  if (beforeDate && isNaN(beforeDate.getTime())) {
+    throw new Error("Invalid toDate timestamp");
+  }
+
   const sentMessages = await emailProvider.getSentMessageIds({
     maxResults: MAX_SENT_MESSAGES,
-    ...(fromDate ? { after: new Date(fromDate) } : {}),
-    ...(toDate ? { before: new Date(toDate) } : {}),
+    ...(afterDate ? { after: afterDate } : {}),

56, the current truthy checks (e.g. fromDate ? ...) drop valid epoch 0 values
and unconditionally call new Date(...) which can produce Invalid Date; change
the conditions to explicit null/undefined checks (e.g. fromDate !== null &&
fromDate !== undefined) and construct Date objects into local variables,
validate each Date with Number.isNaN(date.getTime()) (or similar) before
including them in the getSentMessageIds options; if a Date is invalid, reject
the request or omit the parameter with a clear error/log so you never pass
Invalid Date to emailProvider.getSentMessageIds.

⚠️ Potential issue | 🔴 Critical

Fix truthy checks in date range filtering to prevent dropping valid epoch timestamp.

Lines 125-126 use truthy checks (fromDate &&, toDate &&) that will skip timestamp 0 (Unix epoch, Jan 1 1970), even though it's a valid filter boundary. This is inconsistent with the intended date range filtering.

128, the filter uses truthy checks (fromDate &&, toDate &&) which incorrectly
treat 0 as "no filter"; change those checks to explicit null/undefined checks
(e.g., fromDate !== undefined && fromDate !== null or fromDate != null) so epoch
timestamp 0 is treated as a valid boundary and sentTime comparisons work
correctly; update both fromDate and toDate checks accordingly.

1-21: Export response type for client-side type safety.

Coding guidelines require GET API routes to export their response type using the Get[Feature]Response pattern for type-safe client consumption.

Add this export after the route handler:

import type { ResponseTimeStats } from "@/app/api/user/stats/response-time/controller";

// ... existing code ...

export type GetResponseTimeResponse = ResponseTimeStats;

As per coding guidelines: Always export response types from GET routes using type inference for type-safe client consumption.

18-23: Use explicit null/undefined checks to handle epoch 0.

The truthy checks if (fromDate) and if (toDate) will reject valid timestamp 0 (Unix epoch). This matches the concern from previous reviews and PR objectives.

Apply this diff:

   const dateConditions: Prisma.Sql[] = [];
-  if (fromDate) {
+  if (fromDate != null) {
     dateConditions.push(Prisma.sql`date >= ${new Date(fromDate)}`);
   }
-  if (toDate) {
+  if (toDate != null) {
     dateConditions.push(Prisma.sql`date <= ${new Date(toDate)}`);
   }

This ensures that 0 (epoch) is treated as a valid timestamp while still filtering out null and undefined.

44-57: Add defensive validation for period parameter.

Line 46 uses Prisma.raw(\'${period}'`)with string interpolation. Whileperiod` is constrained by the Zod enum at the route level, the controller should not rely solely on upstream validation. Add a defensive check to explicitly verify the value.

Add validation at the start of the function:

async function getEmailStatsByPeriod(
  options: StatsByPeriodQuery & { emailAccountId: string },
) {
  const { period, fromDate, toDate, emailAccountId } = options;

  // Defensive validation
  const validPeriods = ["day", "week", "month", "year"] as const;
  if (!validPeriods.includes(period)) {
    throw new Error(`Invalid period: ${period}`);
  }

  // ... rest of function

This provides defense-in-depth and makes the code more maintainable if validation logic changes upstream.


69-87: Document assumption about email count limits.

Lines 74-79 and 84-87 convert bigint aggregation results to Number. JavaScript numbers have 53-bit precision (safe up to ~9 quadrillion). While email counts are unlikely to exceed this, consider documenting this assumption or adding a runtime check for very large values.

If you want to be defensive, add a helper:

function safeNumberConversion(value: bigint, fieldName: string): number {
  const num = Number(value);
  if (num > Number.MAX_SAFE_INTEGER) {
    throw new Error(`${fieldName} exceeds safe integer range: ${value}`);
  }
  return num;
}

Alternatively, document the assumption that email counts will remain within safe integer bounds.

**/app/api/**/*.ts: ALL API routes that handle user data MUST use appropriate middleware: use withEmailAccount for email-scoped operations, use withAuth for user-scoped operations, or use withError with proper validation for public/custom auth endpoints
Use withEmailAccount middleware for operations scoped to a specific email account, including reading/writing emails, rules, schedules, or any operation using emailAccountId
Use withAuth middleware for user-level operations such as user settings, API keys, and referrals that use only userId
Use withError middleware only for public endpoints, custom authentication logic, or cron endpoints. For cron endpoints, MUST use hasCronSecret() or hasPostCronSecret() validation
Cron endpoints without proper authentication can be triggered by anyone. CRITICAL: All cron endpoints MUST validate cron secret using hasCronSecret(request) or hasPostCronSecret(request) and capture unauthorized attempts with captureException()
Always validate request bodies using Zod schemas to ensure type safety and prevent invalid data from reaching database operations
Maintain consistent error response format across all API routes to avoid information disclosure while providing meaningful error feedback

**/*.ts: ALL database queries MUST be scoped to the authenticated user/account by including user/account filtering in WHERE clauses to prevent unauthorized data access
Always validate that resources belong to the authenticated user before performing operations, using ownership checks in WHERE clauses or relationships
Always validate all input parameters for type, format, and length before using them in database queries
Use SafeError for error responses to prevent information disclosure. Generic error messages should not reveal internal IDs, logic, or resource ownership details
Only return necessary fields in API responses using Prisma's select option. Never expose sensitive data such as password hashes, private keys, or system flags
Prevent Insecure Direct Object References (IDOR) by validating resource ownership before operations. All findUnique/findFirst calls MUST include ownership filters
Prevent mass assignment vulnerabilities by explicitly whitelisting allowed fields in update operations instead of accepting all user-provided data
Prevent privilege escalation by never allowing users to modify system fields, ownership fields, or admin-only attributes through user input
All findMany queries MUST be scoped to the user's data by including appropriate WHERE filters to prevent returning data from other users
Use Prisma relationships for access control by leveraging nested where clauses (e.g., emailAccount: { id: emailAccountId }) to validate ownership

Learning: In Next.js 15, both `params` and `searchParams` passed to page components in the App Router are Promises that need to be awaited. They should be typed as `Promise<{...}>` and accessed using `await` in server components or React's `use()` hook in client components. This is different from Next.js 14 where they were plain objects.

6-21: LGTM!

The route handler correctly uses withEmailProvider middleware, validates query parameters with the schema, delegates to the controller, and returns the result. Error handling is properly managed by the middleware.

6-25: LGTM!

The route handler correctly uses withEmailAccount middleware with appropriate options, validates query parameters with defaults, and delegates to the controller.

1-5: LGTM!

Imports follow best practices: specific lodash function import, centralized Prisma utility, and proper type imports.


7-9: LGTM!

Response type correctly exported using Awaited<ReturnType<>> pattern for type-safe client consumption.

⚠️ Potential issue | 🟠 Major

Add validation to reject NaN and ensure valid timestamps.

z.coerce.number() can produce NaN from invalid input (e.g., "abc"), which passes validation but creates Invalid Date downstream in the controller.

Apply this diff:

 export const statsByPeriodQuerySchema = z.object({
   period: zodPeriod,
-  fromDate: z.coerce.number().nullish(),
-  toDate: z.coerce.number().nullish(),
+  fromDate: z.coerce.number().finite().nullish(),
+  toDate: z.coerce.number().finite().nullish(),

In apps/web/app/api/user/stats/by-period/validation.ts around lines 4 to 8, the
z.coerce.number() fields can produce NaN from invalid input which then becomes
Invalid Date downstream; update fromDate and toDate to reject NaN and ensure
they are valid timestamps by adding a refinement (after coercion) that checks
Number.isFinite(value) and that the value is an integer and within a sensible
timestamp range (e.g., > 0, optionally <= Date.now()), returning a clear error
message on failure so malformed inputs are rejected at validation time.

⚠️ Potential issue | 🟠 Major

Add validation to reject NaN and ensure valid timestamps.

z.coerce.number() accepts any input and can produce NaN (e.g., from "abc"), which will pass validation but create Invalid Date in downstream code. Additionally, the schema doesn't validate that timestamps are finite or reasonable.

Apply this diff to add proper numeric validation:

 export const responseTimeQuerySchema = z.object({
-  fromDate: z.coerce.number().nullish(),
-  toDate: z.coerce.number().nullish(),
+  fromDate: z.coerce.number().finite().nullish(),
+  toDate: z.coerce.number().finite().nullish(),
 });

This ensures that only finite numbers (excluding NaN, Infinity, -Infinity) are accepted, preventing invalid dates from reaching the controller.

email is used after safeParse but isn’t in responseTimeQuerySchema, and Zod drops unknown keys. This makes email always undefined. Consider adding an email field (e.g., optional string) to the schema, or document that email is intentionally ignored.
