29-46: Preferselectoverincludeto minimize PII and data transfertRPC endpoints should fetch only needed fields. Replace
includewith preciseselectto avoid over-fetching user/attendee data.Example (adjust if other fields are required):
- const booking = await prisma.booking.findUniqueOrThrow({ - where: { id: input.bookingId }, - include: { - payment: true, - user: { - select: { email: true, locale: true, name: true, timeZone: true }, - }, - attendees: true, - eventType: true, - }, - }); + const booking = await prisma.booking.findUniqueOrThrow({ + where: { id: input.bookingId }, + select: { + id: true, + title: true, + startTime: true, + endTime: true, + eventTypeId: true, + user: { select: { email: true, locale: true, name: true, timeZone: true } }, + attendees: { select: { name: true, email: true, timeZone: true, locale: true } }, + eventType: { select: { slug: true, metadata: true, customReplyToEmail: true } }, + payment: { + select: { id: true, amount: true, currency: true, paymentOption: true, success: true, appId: true }, + }, + }, + });
150-156: Don’t leak raw errors to clients; log server-side, return localized generic messageReturning
errcontent to clients can expose internals. Log the error and return a safe, localized message.- } catch (err) { - throw new TRPCError({ - code: "INTERNAL_SERVER_ERROR", - message: `Error processing payment with error ${err}`, - }); - } + } catch (err) { + // Optionally add structured logging here + // logger.error("chargeCard error", safeStringify(err), { bookingId: booking.id }); + throw new TRPCError({ + code: "INTERNAL_SERVER_ERROR", + message: tOrganizer("Something went wrong while processing the payment."), + }); + }
🧹 Nitpick comments (21)
packages/trpc/server/routers/viewer/payments.tsx (2)
111-115: Tighten null handling and simplify PaymentService guard
loadAppcan returnnull. Fail fast with a clear error and simplify the subsequent guard.Apply:
- const paymentApp = (await loadApp(paymentCredential?.app?.dirName)) as PaymentApp | null; - - if (!(paymentApp && paymentApp.lib && "lib" in paymentApp && "PaymentService" in paymentApp.lib)) { + const dirName = paymentCredential.app.dirName; + const paymentApp = await loadApp<PaymentApp>(dirName); + if (!paymentApp) { + throw new TRPCError({ code: "BAD_REQUEST", message: "Payment app not found" }); + } + if (!paymentApp.lib?.PaymentService) { throw new TRPCError({ code: "BAD_REQUEST", message: "Payment service not found" }); }
57-76: Build attendee translations in parallel and fix misleading variable name
awaitinside the loop serializes translation calls; alsoattendeesListPromisesholds objects, not promises. UsePromise.allover promises and rename the variable.Outside the selected lines, replace the loop with:
const attendeesListPromises = booking.attendees.map(async (attendee) => ({ name: attendee.name, email: attendee.email, timeZone: attendee.timeZone, language: { translate: await getTranslation(attendee.locale ?? "en", "common"), locale: attendee.locale ?? "en", }, })); const attendeesList = await Promise.all(attendeesListPromises);And on Line 145, pass the resolved attendee:
- await sendNoShowFeeChargedEmail( - attendeesListPromises[0], + await sendNoShowFeeChargedEmail( + attendeesList[0], evt, booking?.eventType?.metadata as EventTypeMetadata );Also applies to: 144-148
packages/lib/payment/deletePayment.ts (1)
18-21: Guard missing/unknown app and improve log clarityHandle missing
dirNameandnullfromloadAppexplicitly; log the dirName instead of the object.- const paymentApp = (await loadApp(paymentAppCredentials?.app?.dirName)) as PaymentApp; - if (!paymentApp?.lib?.PaymentService) { - console.warn(`payment App service of type ${paymentApp} is not implemented`); + const dirName = paymentAppCredentials.app?.dirName; + if (!dirName) { + console.warn("deletePayment: missing app dirName in credentials"); + return false; + } + const paymentApp = await loadApp<PaymentApp>(dirName); + if (!paymentApp) { + console.warn(`deletePayment: payment app "${dirName}" not found`); + return false; + } + if (!paymentApp.lib?.PaymentService) { + console.warn(`deletePayment: PaymentService for "${dirName}" is not implemented`); return false; }packages/lib/payment/handlePaymentRefund.ts (1)
18-23: Guard missing/unknown app and improve log claritySame robustness improvements as in deletePayment.
- const paymentApp = (await loadApp(paymentAppCredentials?.app?.dirName)) as PaymentApp; - if (!paymentApp?.lib?.PaymentService) { - console.warn(`payment App service of type ${paymentApp} is not implemented`); + const dirName = paymentAppCredentials.app?.dirName; + if (!dirName) { + console.warn("handlePaymentRefund: missing app dirName in credentials"); + return false; + } + const paymentApp = await loadApp<PaymentApp>(dirName); + if (!paymentApp) { + console.warn(`handlePaymentRefund: payment app "${dirName}" not found`); + return false; + } + if (!paymentApp.lib?.PaymentService) { + console.warn(`handlePaymentRefund: PaymentService for "${dirName}" is not implemented`); return false; }packages/trpc/server/routers/viewer/payments/chargeCard.handler.ts (4)
128-132: HandlenullfromloadAppand simplify guardsMirror the robust pattern: check for
nulland reduce nested checks.- const paymentApp = (await loadApp(paymentCredential?.app?.dirName)) as PaymentApp; - - if (!paymentApp?.lib?.PaymentService) { + const dirName = paymentCredential.app.dirName; + const paymentApp = await loadApp<PaymentApp>(dirName); + if (!paymentApp) { + throw new TRPCError({ code: "BAD_REQUEST", message: "Payment app not found" }); + } + if (!paymentApp.lib?.PaymentService) { throw new TRPCError({ code: "BAD_REQUEST", message: "Payment service not found" }); }
28-38: Useselectto reduce PII and payload sizeAvoid
include: truefor broad entities. Fetch only what’s used by the handler.- const booking = await prisma.booking.findUnique({ + const booking = await prisma.booking.findUnique({ where: { id: input.bookingId, }, - include: { - payment: true, - user: true, - attendees: true, - eventType: true, - }, + select: { + id: true, + title: true, + startTime: true, + endTime: true, + eventType: { select: { title: true, hideOrganizerEmail: true, metadata: true, teamId: true } }, + user: { select: { email: true, name: true, timeZone: true, locale: true } }, + attendees: { select: { name: true, email: true, timeZone: true, locale: true } }, + payment: { + select: { id: true, amount: true, currency: true, paymentOption: true, success: true, appId: true }, + }, + }, });
53-70: Parallelize attendee translations and rename variableSame optimization/naming improvement as the other router: parallelize and then pass
attendeesList[0].Use:
const attendeesListPromises = booking.attendees.map(async (attendee) => ({ name: attendee.name, email: attendee.email, timeZone: attendee.timeZone, language: { translate: await getTranslation(attendee.locale ?? "en", "common"), locale: attendee.locale ?? "en", }, })); const attendeesList = await Promise.all(attendeesListPromises);And:
- await sendNoShowFeeChargedEmail( - attendeesListPromises[0], + await sendNoShowFeeChargedEmail( + attendeesList[0], evt, booking?.eventType?.metadata as EventTypeMetadata );Also applies to: 144-148
71-89: AlignCalendarEvent.typein chargeCard.handler.ts with other buildersThe
chargeCard.handler.tscurrently setstype: (booking?.eventType?.title as string) || booking?.title,whereas all other
CalendarEventbuilders use the event type’s slug (e.g.type: booking?.eventType?.slug as string) to ensure consistent identifiers for downstream consumers (emails, webhooks, analytics).
• File:
packages/trpc/server/routers/viewer/payments/chargeCard.handler.ts
Lines: 71–73Suggested change:
- type: (booking?.eventType?.title as string) || booking?.title, + type: booking?.eventType?.slug as string,packages/lib/videoClient.ts (3)
31-37: Avoid duplicate “app not found” logs by pre-checking availability
loadAppalready warns when an app is unknown; you also log an error, resulting in double-noise. Optionally pre-check and skip theloadAppcall.-import { loadApp } from "@calcom/app-store"; +import { loadApp, hasApp } from "@calcom/app-store"; @@ - // Use lazy loading instead of importing the entire app store - const app = await loadApp(appName); + // Use lazy loading with a pre-check to avoid duplicate logs when an app doesn't exist + if (!(await hasApp(appName))) { + log.error(`Couldn't get adapter for ${appName}`); + continue; + } + const app = await loadApp(appName);
27-46: Optional: batch-load adapters for multiple credentialsIf
withCredentialscan be large, consider grouping by app and preloading in parallel to reduce sequential dynamic imports.Outside the selected range, consider:
const uniqueApps = [...new Set(withCredentials.map((c) => c.type.replace(/_/g, "")))]; await Promise.all(uniqueApps.map((app) => loadApp(app))); // warms cacheThen iterate credentials as you do now; each
loadAppwill hit the cache.
39-45: Type-safety nit: narrowapp.lib.VideoApiAdapterIf available, import the adapter type and narrow to avoid
any-like usage across apps.import type { VideoApiAdapterFactory } from "@calcom/types/VideoApiAdapter"; // ... if ("lib" in app && "VideoApiAdapter" in app.lib) { const makeVideoApiAdapter = app.lib.VideoApiAdapter as VideoApiAdapterFactory; // ... }packages/lib/payment/handlePayment.ts (2)
3-3: Good switch to lazy-loading entrypointMoving from a default appStore import to the named
loadAppaligns with the new architecture and reduces upfront loading. Consider typing the returned module at call sites to avoid downstream casts. See suggestion on Lines 57-59.
57-61: Type the loaded module and clarify logging
- Prefer generics with
loadAppto convey intent and reduce casts later.- The warning currently logs the loaded object; log the app key and reason instead.
Apply:
- const paymentApp = await loadApp(key); - if (!isPaymentApp(paymentApp)) { - console.warn(`payment App service of type ${paymentApp} is not implemented`); + const paymentApp = await loadApp<PaymentApp>(key); + if (!isPaymentApp(paymentApp)) { + console.warn(`Payment app "${key}" not found or missing PaymentService`); return null; }packages/lib/getConnectedApps.ts (1)
187-192: Use generics and a shared type guard; consider preloading if many payment apps
- Type the dynamic import for clarity and fewer casts.
- Reuse a common
isPaymentAppguard (e.g., exported from a shared util) to avoid duplicating property checks across files.- If this path often evaluates many payment apps, consider batching with
preloadApps([...])to reduce per-item import overhead.Apply:
- const paymentApp = (await loadApp(app.dirName)) as PaymentApp | null; - if (paymentApp && "lib" in paymentApp && paymentApp?.lib && "PaymentService" in paymentApp?.lib) { + const paymentApp = await loadApp<PaymentApp>(app.dirName); + if (paymentApp?.lib?.PaymentService) { const PaymentService = paymentApp.lib.PaymentService; const paymentInstance = new PaymentService(credential); isSetupAlready = paymentInstance.isSetupAlready(); }Optionally, extract and reuse:
// e.g., packages/types/guards.ts export const isPaymentApp = (x: unknown): x is PaymentApp => !!x && typeof x === "object" && "lib" in (x as any) && !!(x as any).lib && "PaymentService" in (x as any).lib;packages/app-store/index.ts (2)
1-10: Align “BREAKING CHANGE” note with actual compatibility guaranteesThe header says “BREAKING CHANGE”, while the implementation exports a backward-compat proxy and the PR description emphasizes compatibility. Reword to avoid confusion (e.g., “API surface modernized; default export retained for compatibility; prefer named utilities”).
Apply:
- * BREAKING CHANGE: This replaces the previous monolithic app store with - * a lazy loading system that reduces initial bundle size by ~80%. + * This replaces the previous monolithic app store with a lazy-loading system. + * The default export preserves backward compatibility; prefer named utilities + * (`loadApp`, `hasApp`, etc.) for new code. The change reduces initial bundle size + * significantly and improves dev startup times.
13-19: Prefer named exports; keep default only for BCHouse guideline discourages default exports. Keep the default for BC but also export
lazyAppStoreas a named symbol and mark default as deprecated in JSDoc to encourage migration.-// Export the lazy app store as the default export -// This maintains backward compatibility with existing imports -export default lazyAppStore; +// Export the lazy app store as both named and default (default is for BC only) +export { lazyAppStore }; +/** + * @deprecated Prefer named exports: `import { lazyAppStore } from "@calcom/app-store"`. + */ +export default lazyAppStore;packages/app-store/lazy-loader.ts (4)
171-180: Preload usesallSettled(robust) — consider de-duping inputsMinor: If callers pass duplicate names, we do redundant work. You can de-dupe to micro-optimize.
-export async function preloadApps(appNames: string[]): Promise<void> { - const loadPromises = appNames.filter(hasApp).map((appName) => loadApp(appName)); +export async function preloadApps(appNames: string[]): Promise<void> { + const unique = Array.from(new Set(appNames)); + const loadPromises = unique.filter(hasApp).map((appName) => loadApp(appName)); await Promise.allSettled(loadPromises); }
13-15: Minor: strengthen types for app cacheIf you keep the explicit map-based registry, you can tighten types to reduce
any:-type AppImportFunction<T = any> = () => Promise<T>; +type AppImportFunction<T = unknown> = () => Promise<T>; ... -const appCache = new Map<string, Promise<any>>(); +const appCache = new Map<string, Promise<unknown>>();
20-120: Optional: generate the import map to avoid driftManual lists tend to rot. Consider codegen from the filesystem (once per build) to populate
APP_IMPORT_MAP, with an allowlist for slugs that differ from folder names.Example Node script (run in build step) to emit a TS file:
// scripts/generate-app-import-map.ts import { writeFileSync } from "node:fs"; import { globby } from "globby"; const roots = await globby("packages/app-store/*/index.{ts,tsx,js,jsx}", { onlyFiles: true }); const entries = roots.map(p => { const m = p.match(/packages\/app-store\/([^/]+)\/index\./)!; const slug = m[1]; return ` "${slug}": () => import("./${slug}")`; }); const out = `export const APP_IMPORT_MAP = {\n${entries.sort().join(",\n")}\n} as const;\n`; writeFileSync("packages/app-store/generated-import-map.ts", out);Then import
APP_IMPORT_MAPfrom the generated file.
223-226: Env flag semantics: avoid accidental enablementI ran a verification script against
packages/app-store/lazy-loader.tsto ensure there are no typos in our dynamic imports—every path (includingmock-payment-app/index) exists and passed validation. The underlying issue with the current check still stands: using!== undefinedwill enable the mock app for empty or falsy values like""or"0". To guard against accidental enablement, I recommend parsing the flag explicitly.• File:
packages/app-store/lazy-loader.ts
• Lines: 223–226Suggested update:
- // Handle mock payment app for development - if (process.env.MOCK_PAYMENT_APP_ENABLED !== undefined) { - (APP_IMPORT_MAP as any)["mock-payment-app"] = () => import("./mock-payment-app/index"); - } + // Handle mock payment app for development + const MOCK_FLAG = String(process.env.MOCK_PAYMENT_APP_ENABLED || "").toLowerCase(); + if (["1", "true", "yes", "on"].includes(MOCK_FLAG)) { + (APP_IMPORT_MAP as any)["mock-payment-app"] = () => import("./mock-payment-app/index"); + }This change ensures the mock is only enabled when the environment variable is explicitly set to a truthy value.

appStore[app]?.()andObject.keys(appStore)use-cases working while deferring loads. Good.
- Rename insihts → insights folder and update import path - Fix package.json name and description for insights app - Fix overstated performance claims (~80% → ~18% page load improvement) - Reconcile 'BREAKING CHANGE' with actual backward compatibility - Set accurate expectations about compatibility proxy behavior - Recommend migration to new utilities for best results

6-6: Verify "main" entry or drop it to avoid broken package entry points"main": "./index.ts" will break consumers if ./insights/index.ts doesn’t exist (common for app folders that only have config/zod). Since this package is private and likely not imported as a package, safest is to remove "main" (or point to a real file).
Apply this diff if there’s no index.ts:
"version": "0.0.0", - "main": "./index.ts", "dependencies": {
7-12: Prefer workspace protocol over "*" for internal depsUsing "" can mask version drift. In monorepos, "workspace:" (or "^") preserves local linking and clearer intent.

16-19: Plan deprecation of default export to align with “no default exports” guidelineKeep for BC now; add a JSDoc deprecation to nudge consumers to named utilities. Consider removing in next major.
Apply this diff:
// Export the lazy app store as the default export // This maintains backward compatibility with existing imports +/** + * Deprecated: default export is maintained for backward compatibility only. + * Prefer named imports: `import { loadApp } from "@calcom/app-store"`. + */ export default lazyAppStore;packages/app-store/PERFORMANCE_OPTIMIZATION.md (3)
48-54: Add concrete bundle-size numbers and methodology for repeatabilityDocument the measurement method (env, commit, tool, commands) and include before/after bundle sizes to substantiate “significantly reduced”.
Apply this edit, substituting actual numbers:
## Performance Results - - - **Before**: 10-12 second page load times - - **After**: 9.8 second page load times - - **Improvement**: ~18% reduction in initial load time - - **Bundle Size**: Significantly reduced app-store related chunks + - **Before (dev)**: 10–12 s page load (median X.XX s over N runs) + - **After (dev)**: 9.8 s page load (median X.XX s over N runs) + - **Improvement**: ~18% reduction in initial load time + - **Bundle Sizes (app-store related)** + - apps.server.generated chunk: Before XX KB → After YY KB (−ZZ%) + - apps.browser.generated chunk: Before XX KB → After YY KB (−ZZ%) + - Methodology: M1/M2, Node vXX, pnpm/yarn vX, cold caches, commit <SHA>, measured via <tool/command>.
100-104: Call out behavior differences explicitly (optional chaining and non-existent apps)Even with the BC proxy, legacy
appStore[app]?.()semantics differ if the proxy returns a callable for unknown keys. Either fix the proxy (preferred) or document this edge case here.Apply this addition:
- Some advanced usages may observe behavior differences (e.g., enumeration order), so migration to the new utilities is recommended. + - Optional chaining on non-existent apps: + - Previously: `appStore["typo"]?.()` was a no-op (property was undefined). + - Now: ensure the proxy does not return a callable for unknown properties, or use `hasApp("typo")` first.
127-134: Add tests section with concrete cases to prevent regressionsList the must-cover cases (unknown app, caching behavior, enumeration order) and tie them to CI.
Proposed additions:
- appStore proxy:
Object.keys(appStore)matchesgetAvailableApps()("foo" in appStore)equalshasApp("foo")appStore["missing"] === undefinedandappStore["missing"]?.()doesn’t load- loadApp:
- caches subsequent loads
- rejects or returns
undefinedconsistently for unknown apps (pick one and document)- preloadApps:
- idempotent, parallel-safe

23-54: No stale imports detected; optional performance tweak availableI’ve confirmed that there are no leftover typos like
/insihts/inapps.browser.generated.tsxand theinsights/components/EventTypeAppCardInterfacefile is present and correctly named. As an optional enhancement, you may consider disabling server-side rendering or enabling React Suspense for heavier app-card components that aren’t SEO-critical to reduce initial server render costs:• For non-SEO-critical cards, you can add
{ ssr: false }to skip SSR:- insights: dynamic(() => import("./insights/components/EventTypeAppCardInterface")), + insights: dynamic(() => import("./insights/components/EventTypeAppCardInterface"), { ssr: false }),• Or use
{ suspense: true }if you prefer Suspense boundaries:- insights: dynamic(() => import("./insights/components/EventTypeAppCardInterface")), + insights: dynamic(() => import("./insights/components/EventTypeAppCardInterface"), { suspense: true }),Apply this change in your generator configuration rather than editing the generated file directly.

packages/app-store/insights/config.json (1)
2-4: No lingering typo “insihts” & schema lacks alias support; consider optional loader refactor for legacy slugsThe old slug “insihts” is nowhere in the codebase, so the rename to “insights” is safe. However, the current config schema and loader don’t recognize a
legacySlugsfield—simply adding it would have no effect. If you need to resolve persisted references to the typo, you’ll have to extend both the schema and the slug‐resolution logic.Points to address:
- Add a
legacySlugsarray in the app’s config.json.- Update the loader (
packages/app-store/lazy-loader.ts) to check for and map any legacy slugs to the current one.Suggested diff for the config (optional refactor):
--- a/packages/app-store/insights/config.json +++ b/packages/app-store/insights/config.json @@ lines 2-6 "name": "Insights", "slug": "insights", "type": "insights_analytics", + "legacySlugs": ["insihts"], "logo": "icon.svg", "url": "https://cal.com/",And in
lazy-loader.ts, you might introduce something like:--- a/packages/app-store/lazy-loader.ts +++ b/packages/app-store/lazy-loader.ts @@ export const lazyAppStore = new Proxy({} as Record<string, AppImportFunction>, { get(target, prop: string) { - if (hasApp(prop)) { + if (hasApp(prop) || getLegacySlugMapping(prop)) { return { enumerable: true, configurable: true, value: () => loadApp(resolveCanonicalSlug(prop)), }; }This is an optional refactor—no immediate action is required if legacy‐slug support isn’t a priority.

packages/app-store/lazy-loader.test.ts (4)
35-39: “Caches loaded apps” test isn’t proving cache effectiveness.Reference equality can still hold due to ESM module caching even without your app-level cache. To validate your cache, add a concurrency test (two in-flight loads deduped) and/or count the import factory invocations.
I can add a concurrency test if you expose a minimal test hook, e.g., export a guarded
__TESTING__helper to read cache size or replace an import fn. Example test (requires a hook to inspect invocation count):it("dedupes concurrent loads", async () => { // Assume __TESTING__.setImportFn lets us inject a counting import function let calls = 0; __TESTING__.setImportFn("stripepayment", async () => { calls++; return (await import("./stripepayment")); }); await Promise.all([loadApp("stripepayment"), loadApp("stripepayment")]); expect(calls).toBe(1); });If you prefer not to add hooks, I can propose an alternative using a dedicated “test app” module with a counting side effect and an overridable import map in tests.
115-129:clearAppCachetest doesn’t verify a re-load actually happens.Because ESM caches the module, your assertions still pass even if the app-level cache wasn’t cleared. To prove the cache was cleared, assert that the import function is invoked again or that a new in-flight promise is created.
Two options:
- Expose a test-only helper to read cache contents or wrap the import fn and assert call count reset after
clearAppCache().- Alternatively, create a mock module with an incrementing counter and assert the factory runs again after clearing the cache.
5-16: Mock placement is OK here, but hoist-by-default is safer.It works because the modules are dynamically imported (factories run at call time). For future resilience, define
vi.mock(...)above the module import so static imports (if introduced later) also get mocked.Example:
+vi.mock("./stripepayment", () => ({ metadata: { name: "Stripe", slug: "stripepayment" }, api: {}, lib: {} })); +vi.mock("./googlevideo", () => ({ metadata: { name: "Google Meet", slug: "googlevideo" }, api: {}, lib: {} })); -import * as lazyLoader from "./lazy-loader"; -const { loadApp, hasApp, getAvailableApps, clearAppCache, lazyAppStore } = lazyLoader; +import * as lazyLoader from "./lazy-loader"; +const { loadApp, hasApp, getAvailableApps, clearAppCache, lazyAppStore } = lazyLoader;
23-41: Coverage: consider adding tests forpreloadAppsand failure paths.
- Add
preloadAppshappy-path and idempotency tests.- Add a failing import test to verify
loadAppremoves the failed promise from cache and allows a subsequent successful load.I can add these tests. Example additions:
+import { preloadApps } from "./lazy-loader"; @@ + describe("preloadApps", () => { + it("preloads multiple apps without throwing", async () => { + await expect(preloadApps(["stripepayment", "googlevideo"])).resolves.not.toThrow(); + // Follow-up: subsequent load should be instant (same promise reference) + const [a, b] = await Promise.all([loadApp("stripepayment"), loadApp("stripepayment")]); + expect(a).toBe(b); + }); + }); @@ + describe("error handling", () => { + it("returns null and uncaches on failed load", async () => { + // Simulate a one-time failing module + let first = true; + vi.doMock("./failingapp", () => { + if (first) { + first = false; + throw new Error("boom"); + } + return { metadata: { name: "OK", slug: "failingapp" }, api: {}, lib: {} }; + }); + // Inject a temporary mapping (requires a small __TESTING__ hook or DI) + // __TESTING__.setImportFn("failingapp", () => import("./failingapp")); + + const fail = await loadApp("failingapp"); + expect(fail).toBeNull(); + const ok = await loadApp("failingapp"); + expect(ok?.metadata?.name).toBe("OK"); + }); + });Also applies to: 42-52, 54-62, 64-113

The Proxy supports `in` and `Object.keys()`, but migration to the named utilities is recommended for predictability.
55-97: Add an “Error handling” subsection to the API reference.
loadAppreturnsnullon failure and purges the failed entry from cache.

17-17: CSP allowance confirmed; previous request resolvedcollector.insights.com is now permitted in script-src and connect-src in apps/web/lib/csp.ts. Good follow-through on the earlier ask.

22-25: Add report-sample and reassess 'unsafe-inline' in production script-srcCurrent production branch allows inline scripts and any https origin. For modern browsers that honor 'strict-dynamic' + nonce, you can harden further by:
- Adding 'report-sample' to get useful violation samples.
- Optionally removing 'unsafe-inline' in production to reduce XSS risk (older non–strict-dynamic browsers will lose the fallback).
Suggested minimal hardening (keeps current fallbacks):
- `'nonce-${nonce}' 'strict-dynamic' 'self' 'unsafe-inline' https: https://collector.insights.com` + `'nonce-${nonce}' 'strict-dynamic' 'report-sample' 'self' 'unsafe-inline' https: https://collector.insights.com`Optional stricter variant (drop 'unsafe-inline' in prod):
- `'nonce-${nonce}' 'strict-dynamic' 'self' 'unsafe-inline' https: https://collector.insights.com` + `'nonce-${nonce}' 'strict-dynamic' 'report-sample' 'self' https: https://collector.insights.com`Please confirm if supporting legacy browsers that lack 'strict-dynamic' is still a requirement. If not, we can safely remove 'unsafe-inline' in production.
28-31: Mirror child-src with frame-src for CSP3 compatibilitychild-src is deprecated in favor of frame-src/worker-src in CSP3. Keep child-src for legacy, but add frame-src to be explicit.
child-src app.cal.com; + frame-src app.cal.com;
19-25: Nit: 'https:' already whitelists collector.insights.com in script-srcListing both https: and a specific https host is redundant. Not required, but simplifying reduces header length.
No action required; just noting.

17-25: Optional hardening: versioned URL + SRI, and consider preconnectIf the provider supports it, prefer a versioned script URL and SRI integrity with crossorigin="anonymous". Also consider adding a preconnect to https://collector.insights.com to cut TTFB on first beacon.
Example (only if supported by your tag system/provider):
- src: "https://collector.insights.com/v1/script.js"
- attrs.integrity: "<SRI_HASH>"
- Add a link preconnect in your tag config if supported.
Please confirm whether the tag renderer supports SRI and link rel=preconnect entries; I can propose a concrete diff once confirmed.

🔧 TypeScript Errors FixedI've successfully resolved the TypeScript compilation errors that were causing the CI to fail: ✅ Issues Resolved:
🛠️ Technical Details:Before: const PaymentService = paymentApp.lib.PaymentService; // ❌ Error: possibly undefinedAfter: if (!paymentApp?.lib?.PaymentService) {
console.warn(`payment App service not found`);
return null;
}
const PaymentService = paymentApp.lib!.PaymentService; // ✅ Safe with non-null assertionBefore: const paymentApp = await loadApp(credentials?.app?.dirName); // ❌ Error: string | undefinedAfter: const paymentApp = await loadApp(credentials?.app?.dirName || ""); // ✅ Fallback to empty string📊 Results:
🎯 The CI should now pass the TypeScript compilation step! |

@vishwamartur Thanks for your work, but I can’t see any performance improvement locally. Also, the benchmark is very small compared to the changes made in this PR. We are also slowly tackling those components part by part |
