Conversation
Co-authored-by: Yxmura <96625893+Yxmura@users.noreply.github.com>
WalkthroughProject migrates from Vite to Next.js App Router. Adds app/ pages, layout, loading, not-found, and centralized providers. Replaces react-router-dom with a Next.js navigation layer. Introduces SSR-safe guards, environment variable changes, and ESLint/TS/postcss/Next configs. Removes Vite configs, index.html, main entry, and legacy App bootstrap. Changes

⚠️ Outside diff range comments (3)
src/components/DonateButton.tsx (1)
6-11: Preloading conflicts with lazy loading strategy.The preload logic (lines 6-11) and the
loading="lazy"attribute (line 25) work against each other. Preloading eagerly fetches the image on mount, while lazy loading defers it until needed. This negates the performance benefit of lazy loading and may waste bandwidth if the button scrolls out of view.Consider one of these approaches:
- Option 1 (recommended): Remove the preload logic and keep
loading="lazy"for bandwidth efficiency- Option 2: Remove
loading="lazy"and keep the preload if the button is always visible and critical to first paintApply this diff to remove the preload (Option 1):
- useEffect(() => { - // Preload the button image for better performance - const img = new Image(); - img.src = - "https://img.buymeacoffee.com/button-api/?text=Buy us a pizza&emoji=🍕&slug=renderdragon&button_colour=9b87f5&font_colour=ffffff&font_family=Inter&outline_colour=000000&coffee_colour=FFDD00"; - }, []); -Or apply this diff to remove lazy loading (Option 2):
<img src="https://img.buymeacoffee.com/button-api/?text=Buy us a pizza&emoji=🍕&slug=renderdragon&button_colour=9b87f5&font_colour=ffffff&font_family=Inter&outline_colour=000000&coffee_colour=FFDD00" alt="Buy us a pizza" className="w-auto h-auto" - loading="lazy" />src/hooks/useHeartedResources.ts (1)
38-47: Critical: Unguardedwindowaccess breaks SSR.Line 46 directly accesses
window.dispatchEventwithout an SSR guard, which will cause a ReferenceError during server-side rendering in Next.js. This breaks the SSR-safe pattern established by the changes on lines 22 and 32.Apply this diff to guard the
windowaccess:const toggleHeart = (resourceId: string) => { const current = getLocalHeartedResources(); const newHearted = current.includes(resourceId) ? current.filter(id => id !== resourceId) : [...current, resourceId]; setLocalHeartedResources(newHearted); // Force re-render by dispatching a custom event - window.dispatchEvent(new CustomEvent('localFavoritesChanged')); + if (typeof window !== 'undefined') { + window.dispatchEvent(new CustomEvent('localFavoritesChanged')); + } };src/pages/Account.tsx (1)
62-106: Consider more robust metadata synchronization.The profile update flow includes a 500ms hardcoded delay (line 93) before calling
refreshUser()to wait for metadata synchronization. This approach has several risks:
- Race condition: 500ms may not be sufficient under high load or network latency
- Unnecessary delay: May be slower than needed when sync is fast
- Silent failures: If sync takes longer than 500ms, the UI may show stale data without indication
Consider one of these more robust approaches:
Option 1: Polling with timeout
// Poll for updated metadata with timeout const waitForMetadataSync = async (maxAttempts = 5, delayMs = 200) => { for (let i = 0; i < maxAttempts; i++) { await new Promise(resolve => setTimeout(resolve, delayMs)); await refreshUser(); const currentUser = supabase.auth.getUser(); if (currentUser.data.user?.user_metadata?.display_name === displayName) { return true; } } return false; }; const synced = await waitForMetadataSync(); if (synced) { toast.success("Profile updated successfully!"); } else { toast.success("Profile updated! Changes may take a moment to reflect."); }Option 2: Optimistic update with eventual consistency
// Update UI immediately, sync in background await refreshUser(); // Immediate refresh toast.success("Profile updated successfully!"); // Background verification (optional) setTimeout(async () => { await refreshUser(); }, 2000);

src/components/DonateButton.tsx (1)
8-10: Extract duplicate image URL to a constant.The image URL appears twice (lines 9-10 and line 22), violating the DRY principle. If the URL needs updating (e.g., changing colors or text), both locations must be changed, creating a maintenance risk.
Apply this diff to extract the URL:
+'use client'; + +import { useEffect } from "react"; + +const DONATE_BUTTON_IMAGE_URL = + "https://img.buymeacoffee.com/button-api/?text=Buy us a pizza&emoji=🍕&slug=renderdragon&button_colour=9b87f5&font_colour=ffffff&font_family=Inter&outline_colour=000000&coffee_colour=FFDD00"; + const DonateButton = () => { useEffect(() => { // Preload the button image for better performance const img = new Image(); - img.src = - "https://img.buymeacoffee.com/button-api/?text=Buy us a pizza&emoji=🍕&slug=renderdragon&button_colour=9b87f5&font_colour=ffffff&font_family=Inter&outline_colour=000000&coffee_colour=FFDD00"; + img.src = DONATE_BUTTON_IMAGE_URL; }, []); return ( <a href="https://www.buymeacoffee.com/renderdragon" target="_blank" rel="noopener noreferrer" className="fixed bottom-6 left-6 z-40 transition-transform duration-300 hover:scale-105" aria-label="Buy us a pizza" > <img - src="https://img.buymeacoffee.com/button-api/?text=Buy us a pizza&emoji=🍕&slug=renderdragon&button_colour=9b87f5&font_colour=ffffff&font_family=Inter&outline_colour=000000&coffee_colour=FFDD00" + src={DONATE_BUTTON_IMAGE_URL} alt="Buy us a pizza" className="w-auto h-auto" loading="lazy" /> </a> ); };Also applies to: 22-22
src/hooks/useHeartedResources.ts (1)
31-34: LGTM! SSR-safe localStorage write.The guard on line 32 correctly prevents server-side execution. The early return ensures no localStorage operations occur in non-browser environments.
Consider wrapping
localStorage.setItemin a try-catch block to handle quota exceeded or disabled localStorage scenarios:const setLocalHeartedResources = (resources: string[]) => { if (typeof window === 'undefined') return; - localStorage.setItem(localStorageKey, JSON.stringify(resources)); + try { + localStorage.setItem(localStorageKey, JSON.stringify(resources)); + } catch { + // Handle quota exceeded or disabled localStorage + } };src/pages/TOS.tsx (1)
1-2: LGTM! Client directive appropriate for Helmet usage.The
'use client'directive is correctly added to supportreact-helmet-asyncfor dynamic meta tag management. This aligns with the PR's client-side rendering strategy.Optional: Remove unused import.
Line 3 imports
useEffectbut it's never used in the component. Consider removing it to keep imports clean.app/faq/page.tsx (1)
1-3: Consider static rendering for FAQ page.The FAQ page is configured with
dynamic = 'force-dynamic'andrevalidate = 0, forcing server-side rendering on every request. Since FAQ content is typically static, consider:
- Removing
dynamic = 'force-dynamic'to allow static generation- Using ISR with a longer revalidation period (e.g.,
revalidate = 3600) if content updates occasionallydynamicParams = trueis unnecessary as this route has no dynamic segmentsIf FAQ content is truly static, apply this diff:
-export const dynamic = 'force-dynamic'; -export const dynamicParams = true; -export const revalidate = 0; +// Static generation - rebuild on deploymentOr if it updates occasionally:
-export const dynamic = 'force-dynamic'; -export const dynamicParams = true; -export const revalidate = 0; +export const revalidate = 3600; // Revalidate every hourapp/tos/page.tsx (1)
1-3: Reconsider routing config for static TOS page.The configuration
dynamic='force-dynamic'andrevalidate=0disables all caching and static optimization. For a Terms of Service page that likely contains static content, this forces every request to regenerate the page on the server, which is inefficient.Unless the TOS content is truly dynamic (e.g., fetched from a database or CMS), consider removing these exports to allow Next.js to statically optimize this page:
-export const dynamic = 'force-dynamic'; -export const dynamicParams = true; -export const revalidate = 0; - import TOS from '@/pages/TOS'; export default function TOSPage() { return <TOS />; }If the content does change occasionally, use ISR with a reasonable revalidation period instead:
export const revalidate = 3600; // Revalidate once per hourapp/construction/page.tsx (1)
1-3: Reconsider routing config for static construction page.Similar to the TOS page,
dynamic='force-dynamic'andrevalidate=0disables caching for what appears to be a static "under construction" page. This configuration forces server-side rendering on every request.Unless this page displays dynamic construction status, consider removing the routing config to enable static optimization:
-export const dynamic = 'force-dynamic'; -export const dynamicParams = true; -export const revalidate = 0; - import Construction from '@/pages/Construction'; export default function ConstructionPage() { return <Construction />; }app/community/page.tsx (1)
1-3: Review routing config based on Community page data requirements.This page uses
dynamic='force-dynamic'which disables all caching. This is appropriate if the Community component fetches real-time data (e.g., latest posts, user activity). However, if the content is relatively static or can tolerate some staleness, consider using ISR for better performance.If community content doesn't need to be real-time, enable ISR:
-export const dynamic = 'force-dynamic'; -export const dynamicParams = true; export const revalidate = 0; +export const revalidate = 60; // Revalidate every minuteapp/generators/page.tsx (1)
1-9: Review blanket routing config pattern across app/ pages.This file follows the same
dynamic='force-dynamic'+revalidate=0pattern seen across multiple app/ pages (TOS, Construction, Community, Generators). While this ensures consistency, it may be over-configured for pages with static or semi-static content.Consider differentiating routing strategies based on content type:
- Static pages (TOS, Construction): Remove routing config for static optimization
- Semi-static pages (Generators listings): Use ISR with reasonable revalidation
- Dynamic pages (Music Copyright with auth): Keep
force-dynamicThis approach balances performance (caching) with data freshness requirements. The current blanket approach prioritizes consistency but may impact performance and hosting costs.
app/providers.tsx (1)
35-35: Consider explicit QueryClient configuration.The QueryClient is created with default settings. For production apps, consider configuring retry logic, staleTime, and error handling explicitly.
Example configuration:
- const [queryClient] = useState(() => new QueryClient()); + const [queryClient] = useState(() => new QueryClient({ + defaultOptions: { + queries: { + staleTime: 5 * 60 * 1000, // 5 minutes + retry: 1, + refetchOnWindowFocus: false, + }, + }, + }));src/lib/navigation.tsx (1)
45-57: Improve Navigate component stability.The component has two minor issues:
- Including
routerin deps causes unnecessary effect re-runs (router ref is stable)- No abort mechanism if component unmounts during navigation
Apply this diff:
export function Navigate({ to, replace = false }: { to: string; replace?: boolean }) { const router = useRouter(); useEffect(() => { if (replace) { router.replace(to); } else { router.push(to); } - }, [to, replace, router]); + }, [to, replace]); return null; }src/pages/ResourcesHub.tsx (1)
18-18: Consider migrating from react-helmet-async to Next.js Metadata API.This client component uses
Helmetfor meta tags. In Next.js App Router, metadata should be defined in the route'spage.tsxusing the Metadata API orgenerateMetadatafunction for better SEO and performance.Move metadata to
app/resources/page.tsx:// app/resources/page.tsx import { Metadata } from 'next'; export const metadata: Metadata = { title: 'Resources Hub', description: 'Explore a vast collection of resources for RenderDragon.', openGraph: { title: 'Resources Hub', description: 'Explore a vast collection of resources for RenderDragon.', images: ['https://renderdragon.org/ogimg/resources.png'], url: 'https://renderdragon.org/resources', }, twitter: { card: 'summary_large_image', title: 'Resources Hub', images: ['https://renderdragon.org/ogimg/resources.png'], }, };Then remove the Helmet component from ResourcesHub.tsx.

src/pages/Index.tsx (1)
16-34: Consider using Next.js built-in font optimization.While the current dynamic font loading works, Next.js 15 provides built-in Google Font optimization through
next/font/googlethat offers better performance with automatic font subsetting, preloading, and self-hosting.Example migration:
import { Press_Start_2P, VT323, Chakra_Petch, Inter } from 'next/font/google' const pressStart2P = Press_Start_2P({ weight: '400', subsets: ['latin'], variable: '--font-press-start' }) const vt323 = VT323({ weight: '400', subsets: ['latin'], variable: '--font-vt323' }) // Apply in layout.tsx className or use CSS variablesThis eliminates the client-side font loading and improves Core Web Vitals. However, this can be deferred as a follow-up optimization.
.eslintrc.json (1)
1-12: Consider re-enabling stricter lint rules post-migration.Several lint rules are disabled that help catch common issues:
@typescript-eslint/no-unused-varshelps identify dead code@typescript-eslint/no-explicit-anyimproves type safetyreact-hooks/exhaustive-depsprevents stale closure bugsWhile this relaxed configuration may ease the migration, consider re-enabling these rules incrementally to improve code quality once the migration is stable.
src/pages/Guides.tsx (1)
324-338: Consider improving type safety for the code component.The
codecomponent now infers inline vs. block code by checking forclassNamepresence rather than an explicitinlineparameter. While this approach should work (block code receives a language class), theanytype reduces type safety.Consider using proper types from
react-markdown:-code: ({ children, ...props }: any) => { - const inline = !props.className; +code: ({ children, className, ...props }: { children?: React.ReactNode; className?: string; [key: string]: any }) => { + const inline = !className; if (inline) {Alternatively, verify that
react-markdownprovides component prop types you can use directly.src/lib/supabaseClient.ts (1)
3-4: Document or enforce Supabase env vars
You assertNEXT_PUBLIC_SUPABASE_URLandNEXT_PUBLIC_SUPABASE_ANON_KEYwith!; MIGRATION.md only provides example placeholders and no.envfiles are loaded. Add a.env.localwith real values or guard against missing vars to prevent runtime errors.app/layout.tsx (1)
46-56: Prefer Next.js APIs for head management.Manually adding links to the
<head>element bypasses Next.js's built-in metadata system. For better optimization and SSR support:
- Move the canonical URL to the
metadataobject usingmetadataBaseand automatic canonical generation- Use
next/font/googlefor font optimization instead of external stylesheet linksApply this diff to use Next.js font optimization:
+import { Press_Start_2P, VT323, Chakra_Petch, Inter } from 'next/font/google'; + +const pressStart2P = Press_Start_2P({ + weight: '400', + subsets: ['latin'], + variable: '--font-press-start' +}); + +const vt323 = VT323({ + weight: '400', + subsets: ['latin'], + variable: '--font-vt323' +}); + +const chakraPetch = Chakra_Petch({ + weight: ['300', '400', '500', '600', '700'], + subsets: ['latin'], + variable: '--font-chakra-petch' +}); + +const inter = Inter({ + weight: ['300', '400', '500', '600', '700'], + subsets: ['latin'], + variable: '--font-inter' +}); + export const metadata: Metadata = { + metadataBase: new URL('https://renderdragon.org'), title: 'Renderdragon - Minecraft Content Creator Tools & Assets',Then update the layout to use font variables:
export default function RootLayout({ children, }: { children: React.ReactNode; }) { return ( - <html lang="en"> - <head> - <link rel="canonical" href="https://renderdragon.org" /> - <link - rel="stylesheet" - href="https://fonts.googleapis.com/css2?family=Press+Start+2P&family=VT323&family=Chakra+Petch:wght@300;400;500;600;700&display=swap" - /> - <link - rel="stylesheet" - href="https://fonts.googleapis.com/css2?family=Inter:wght@300;400;500;600;700&display=swap" - /> - </head> + <html lang="en" className={`${pressStart2P.variable} ${vt323.variable} ${chakraPetch.variable} ${inter.variable}`}> <body> <Providers>{children}</Providers> </body> </html> ); }MIGRATION.md (1)
90-95: Consider reordering next steps for better prioritization.The next steps are good, but the order could better reflect typical post-migration priorities. Deployment configuration typically comes before optional API migration.
## Next Steps -1. Consider migrating from `react-helmet-async` to Next.js Metadata API -2. Optionally migrate API routes from Express to Next.js API routes -3. Configure environment variables with `NEXT_PUBLIC_` prefix -4. Set up deployment configuration for Next.js (Vercel, etc.) +1. Set up deployment configuration for Next.js (Vercel, self-hosted, etc.) +2. Configure all environment variables with `NEXT_PUBLIC_` prefix +3. Consider migrating from `react-helmet-async` to Next.js Metadata API +4. Optionally migrate API routes from Express to Next.js API routespackage.json (2)
87-100: Review transitional dependencies post-migration.Several dependencies related to the old Vite setup remain in the dependency list:
Dependencies to review:
react-router-dom(line 100): Still present despite migrating to Next.js App Router. If this is only used by the@/lib/navigationcompatibility layer, consider:
- Adding a comment in package.json explaining its transitional role
- Planning to remove it once all components use native Next.js navigation
- Checking if you can use Next.js
useRouter/Linkdirectly instead
react-helmet-async(line 94): MIGRATION.md recommends replacing this with Next.js Metadata API. Since you're using Next.js 15.3, you have access to:
- File-based
metadataexports in page.tsx filesgenerateMetadatafunction for dynamic metadata- This would resolve the SSR compatibility issues mentioned
react-helmet(line 93): Bothreact-helmetandreact-helmet-asyncare present. You likely only need one.#!/bin/bash # Verify react-router-dom usage rg -n "from ['\"]react-router-dom['\"]" --type ts --type tsx # Check react-helmet usage vs react-helmet-async rg -n "from ['\"]react-helmet['\"]" --type ts --type tsx rg -n "from ['\"]react-helmet-async['\"]" --type ts --type tsx # Find Helmet component usage to assess migration effort rg -n "<Helmet" --type ts --type tsx | head -20Based on learnings: Next.js 15.3.2 has strong metadata support; migrating from react-helmet-async to Next.js metadata would resolve SSR issues and reduce bundle size.
111-123: LGTM! DevDependencies updated for Next.js.The devDependencies correctly include
eslint-config-nextmatching the Next.js version, and have removed Vite-specific tooling.Optional enhancement:
Consider adding these helpful Next.js development tools:"devDependencies": { "@tailwindcss/typography": "^0.5.16", "@types/node": "^22.15.17", "@types/react": "^18.3.21", "@types/react-dom": "^18.3.7", "@types/react-helmet": "^6.1.11", "autoprefixer": "^10.4.21", "eslint": "^9.26.0", "eslint-config-next": "^15.3.2", + "@next/bundle-analyzer": "^15.3.2", "postcss": "^8.5.3", "tailwindcss": "^3.4.17", "typescript": "^5.8.3" }

Reconsider force-dynamic on all pages.
Every page in this PR exports dynamic = 'force-dynamic' and revalidate = 0, which disables static optimization and ISR caching—Next.js's core performance features. This pattern suggests client-only rendering across the entire app.
Unless all pages require request-time data or user-specific content, consider:
- Removing these exports from pages that can be static or ISR-cached
- Using
dynamic = 'force-static'for pages with no dynamic data - Leveraging ISR with appropriate
revalidatevalues for pages with data that changes infrequently

Reconsider force-dynamic on static pages
Most pages under app/ (e.g. app/privacy/page.tsx, app/account/page.tsx, app/admin/page.tsx) don’t call any request-time APIs, so exporting
export const dynamic = 'force-dynamic'
export const revalidate = 0unnecessarily disables Next.js’s static and ISR optimizations. Remove these exports from pages without dynamic data (or use dynamic = 'force-static') and, where needed, configure an appropriate revalidate interval for ISR.
🤖 Prompt for AI Agents
In app/privacy/page.tsx around lines 1 to 9, the file exports `dynamic =
'force-dynamic'` and `revalidate = 0` which forces request-time rendering even
though this page has no request-time data; remove those exports (or set `export
const dynamic = 'force-static'`) and, if you want ISR, set an appropriate
`revalidate` interval (e.g., a positive number of seconds) instead of 0 so the
page can benefit from static/ISR optimizations.

Clarify the react-helmet-async error guidance.
The note states that prerendering errors "can be safely ignored for development," but also mentions the app is "fully client-side rendered" and that all routes already have export const dynamic = 'force-dynamic'. This creates confusion:
- If all pages are client-side rendered with
'use client'and dynamic routes, when would prerendering errors occur? - Are these errors appearing during
next buildornext dev? - If solution 2 is "already done," are these errors still present?

In MIGRATION.md around lines 59–61, the guidance about prerendering errors from
react-helmet-async is ambiguous and contradictory; update the note to state
exactly when these errors appear (e.g., during next build vs next dev), confirm
whether the dynamic setting and 'use client' directives already prevent
prerendering (or whether errors still occur), and if errors persist explain
likely causes (shared imports used by server components or metadata applied
outside client boundaries) and give concrete next steps: indicate environment
where they were observed, state whether the issue is resolved or still requires
work, and recommend either removing react-helmet-async in favor of Next.js
metadata, ensuring all affected files use 'use client' or making routes
force-dynamic, or provide a repro and log guidance so maintainers can verify and
resolve.
| ## Known Issues | ||
|
|
||
| 1. **React Helmet Async**: The `react-helmet-async` library has SSR compatibility issues with Next.js. The application uses client-side rendering (`'use client'`) for all pages, which bypasses this issue in development mode. | ||
|
|
||
| 2. **API Routes**: The backend API routes are kept separate (in the `api/` directory) and proxied through Next.js configuration. They can be migrated to Next.js API routes if needed. | ||
|
|
||
| ## API Integration | ||
|
|
||
| The project uses a proxy configuration in `next.config.js` to forward API requests from `/api/*` to `http://localhost:3000/api/*`. The Express server (`server.js`) should be running separately to handle these requests. | ||

Server.js currently binds to port 3000—the same as the Next.js dev server—causing the /api rewrite to proxy back into itself. You must:

In package.json around lines 5 to 9, the review asks to either restore Express
server startup scripts if the Express API is still used, or remove/document
references to server.js and proxy in MIGRATION.md if Express was removed; if
retaining Express, add appropriate scripts (e.g., a start script that launches
server.js and a dev script that runs node server.js or nodemon) and ensure
package.json includes any required dependencies and docs; if removing Express,
open MIGRATION.md and remove or update any instructions mentioning server.js and
the proxy requirement and add a short note explaining the change and migration
steps for callers previously relying on the Express proxy.

Replace react-router-dom with Next.js navigation.
The PR migrates from React Router to Next.js App Router, but this component still imports Link from react-router-dom. According to the PR summary, a compatibility layer exists at src/lib/navigation.tsx that exposes Next.js-compatible Link, useLocation, and Navigate APIs.
Apply this diff to use the Next.js navigation layer:
-import { Link } from "react-router-dom"

Replace all react-router-dom imports with Next.js navigation
The following files still import from react-router-dom. Update each to import from @/lib/navigation (use the matching API: Link, useNavigate, etc.):
- src/hooks/use-auth.ts
- src/pages/NotFound.tsx
- src/components/Hero.tsx
- src/components/auth/UserMenu.tsx
Example diff:
-import { useNavigate } from 'react-router-dom'
+import { useNavigate } from '@/lib/navigation'-import { Link } from 'react-router-dom'
+import { Link } from '@/lib/navigation'Then verify no imports remain:

In src/components/Hero.tsx around line 4, the file imports Link from
"react-router-dom"; replace that import with the matching API from your Next.js
navigation wrapper by changing it to import { Link } from "@/lib/navigation".
Ensure any usage of Link remains compatible with the wrapper API, update props
if needed, and repeat the same replacement for the other files listed; after
changes run the provided ripgrep command to verify no remaining "from
'react-router-dom'" imports.

Critical limitation: useLocation returns empty search, hash, and state.
The compatibility shim returns hardcoded empty values for search, hash, and state. This breaks React Router code that relies on:
- Query parameters (
location.search) - URL fragments (
location.hash) - Navigation state (
location.state)
Verify no existing code depends on these location properties:
#!/bin/bash
# Find usages of useLocation that access search, hash, or state
rg -n -B 2 -A 5 'useLocation\(\)' | rg '\.search|\.hash|\.state'If dependencies exist, implement proper Next.js equivalents:
- For search params: use
useSearchParams()from 'next/navigation' - For hash: use
window.location.hashwith client-side guard - For state: use query params or a state management solution (Next.js doesn't support location.state)
🤖 Prompt for AI Agents
In src/lib/navigation.tsx around lines 33 to 42, the shimbed useLocation returns
hardcoded empty search, hash, and state which breaks callers expecting actual
query string, fragment, or navigation state; update the hook to derive search
from Next's useSearchParams(), derive hash from window.location.hash only on the
client (guard with a check for typeof window !== 'undefined' or useEffect), and
document that location.state is not supported in Next.js — either map required
state into query params or recommend a shared state solution (context/store) and
return null for state if no alternative is implemented.

Enable strictNullChecks for better type safety.
Setting strictNullChecks: false weakens TypeScript's null safety guarantees and can lead to runtime null/undefined errors. This is particularly risky in a large migration where SSR introduces new null-handling edge cases.
Remove this line to enable strict null checks (inherits from strict: false, but you should consider enabling strict mode gradually):

"noUnusedLocals": false,

In tsconfig.json around line 19, the compiler option "strictNullChecks": false
weakens null/undefined safety; remove this line (so the project inherits
strictNullChecks from higher-level config) or change it to "true" to enable null
checks; if you must defer, replace the line with a TODO comment and add a
tracking issue ID in the comment referencing a ticket to enable strictNullChecks
(and consider enabling full "strict" gradually).
