54-68: Type mismatch:publicEnvparameter typed asstringbut receives an object.The
publicEnvparameter is typed asstring, but at line 189 it receivesparsed.datawhich is an object (result of Zod schema parse). The function works at runtime becauseJSON.stringify(publicEnv)handles objects, but the type annotation is incorrect.Suggested fix
-function persistBakedArtifacts(publicEnv: string, ASSETS_FROM_S3: boolean) { +function persistBakedArtifacts(publicEnv: Record<string, unknown>, ASSETS_FROM_S3: boolean) {
🧹 Nitpick comments (2)
config/securityHeaders.ts (1)
1-46: Add explicit return type annotation for type safety.The function lacks a return type annotation. Per coding guidelines for TypeScript, consider adding explicit typing.
Suggested improvement
-export function createSecurityHeaders(apiEndpoint = "") { +export function createSecurityHeaders(apiEndpoint = ""): Array<{ key: string; value: string }> {next.config.ts (1)
135-138: Consider stronger typing for webpack config.The
config: anytype loses type safety. While Next.js webpack config typing can be complex, you could useConfigurationfrom webpack if stricter typing is desired.Optional: Import webpack Configuration type
import type { Configuration } from "webpack"; // ... webpack: ( config: Configuration, { dev, isServer }: { dev: boolean; isServer: boolean } ) => {Note: This may require handling type narrowing for some config properties.

config/securityHeaders.ts (1)
9-9: Verify: CSPconnect-src *weakens protection.The
connect-src * 'self'directive contains a wildcard that allows connections to any origin, which largely defeats CSP's network restriction purpose. This appears to be existing behavior extracted from the previous config. If intentional due to wallet/IPFS requirements, consider documenting why the wildcard is necessary. Otherwise, consider tightening to explicit allowed origins.next.config.ts (3)
1-14: LGTM on imports and module setup.The extraction of security headers to a dedicated module improves maintainability. The explicit
NextConfigtype import and path alias usage (@/config/securityHeaders) follow best practices.
90-162: LGTM onsharedConfigwith proper typing.The
NextConfigreturn type annotation and typed parameters improve type safety. ThereactCompiler: truesetting aligns with coding guidelines for Next.js 16. Based on learnings, this enables auto-memoization to reduce manualuseMemo/useCallbackusage.
258-295: LGTM on Sentry configuration and export.The bracket notation for
process.env["CI"]is consistent with the codebase style. The typed default export(phase: string): NextConfigproperly annotates the config factory. Noeslintoptions are present, which aligns with Next.js 16 guidelines per learnings.
