🦉 Allocation of Resources Without Limits or Throttling

[snyk-io]

This is a major upgrade, spanning two major versions from Next.js 13 to 15. It introduces significant breaking changes that require mandatory code modifications, dependency updates, and careful review of application behavior, particularly around caching.

Key Breaking Changes in Next.js 15:

• Caching is Now Opt-In: This is the most critical behavioral change. In v15, fetch requests, GET Route Handlers, and client-side navigations are no longer cached by default. [5, 6] You must explicitly opt into caching where needed (e.g., fetch(..., { cache: 'force-cache' })) to avoid performance regressions or unexpected dynamic behavior. [15]
• Asynchronous Request APIs: Previously synchronous APIs like cookies(), headers(), draftMode(), params, and searchParams are now asynchronous and must be awaited. [4, 5, 15] A codemod is available to help automate this migration: npx @next/codemod@canary next-async-request-api. [5]
• React 19 Required: Next.js 15 requires React 19 (or its RC version), which involves updating react and react-dom dependencies. [2, 6]

Key Breaking Changes in Next.js 14:

• Node.js Version: The minimum required Node.js version was raised to 18.17. [7, 8]
• next export Removed: The next export command has been removed. For static exports, you must now use the output: 'export' option in your next.config.js file. [7, 8]
• Import Changes: The @next/font package is removed in favor of the built-in next/font. The ImageResponse import was moved from next/server to next/og. Codemods are available for both changes. [7, 8]

Recommendation:
This upgrade is high-risk and requires significant developer action.

1. Run the provided codemods to handle API and import changes. [5, 7]
2. Thoroughly review your application's data fetching and caching strategy to explicitly opt-in where caching is needed. [5]
3. Update Node.js to at least version 18.17 and upgrade React dependencies to v19. [7, 2]
4. Test your application extensively, paying close attention to data freshness on navigation and API route responses.

Overview

This PR upgrades the usage-based-subscriptions app from Next.js 13.4.12 to 15.5.16 and refreshes the dependency lockfile accordingly.
It aligns related packages (like next-superjson, @swc/helpers, styled-jsx, and postcss) with the new Next.js version and updates pnpm lockfile settings.
The change also introduces optional image-processing dependencies (sharp and associated platform binaries) that are now used by newer Next.js versions.

Key Changes

• Bump next from 13.4.12 to 15.5.16 in usage-based-subscriptions, requiring Node.js >=18.18.0 / >=20 and widening React/ReactDOM peer ranges.
• Update the pnpm lockfile to reflect the new Next.js version, including new @next/env and all platform-specific @next/swc-* binaries at 15.5.16.
• Refresh transitive dependencies to versions compatible with Next 15 (e.g. @swc/helpers → 0.5.15 with tslib 2.8.1, postcss → 8.4.31, styled-jsx → 5.1.6, caniuse-lite → 1.0.30001792).
• Add optional sharp 0.34.5 and its platform-specific helper packages, plus detect-libc, semver, and @img/* packages for image handling in Next 15.
• Remove no-longer-needed dependencies busboy, streamsearch, and zod that were previously pulled in by Next 13.
• Configure pnpm lockfile settings (autoInstallPeers: true, excludeLinksFromLockfile: false) to align with current tooling behavior.

Risks & Considerations

• Next.js 15 introduces breaking and behavioral changes relative to 13; the app should be regression-tested thoroughly (routing, data fetching, middleware, and any custom server logic).
• New Node.js engine constraints (>=18.18.0 / >=20) may break environments still on older Node versions.
• Optional sharp and @img/* binaries may cause install or build issues on unusual platforms/architectures; CI and deployment environments should be verified.
• New or updated peer dependencies (e.g. optional @playwright/test, babel-plugin-react-compiler) might affect tooling if added later; ensure versions remain compatible.
• Changes to styled-jsx and postcss could subtly affect styling or CSS processing; visual and styling checks are recommended.
