Pattern

Environment-Specific Hot Reload

inconsistent-incremental-refresh

Next.js/HTMX module updates can fail to apply or apply inconsistently after reload because build/runtime constraints (module export casing, transition/attribute changes, file-scope rules, external scanners) prevent the expected incremental update path, causing full reloads or missing UI effects.

Resend emails do not send when Next.js is built with output: "export"

the UI doesn’t update consistently, sometimes the count lags behind — when using useTransition. Tension: especially after fast re-renders or route changes. Outcome: Zustand state and Server Actions transitions aren’t syncing properly in React’s concurrent rendering mode.

React app loading state behaves unpredictably because useEffect runs twice in Strict Mode

I'm building a Next.js 14 app that uses Zustand with the persist middleware to store authentication tokens and user info. Tension: authenticated pages redirect me to /error/unauthorized. Outcome: React has detected a change in the order of Hooks...

React context data loaded from localStorage in a Next.js app either requires disabling SSR to avoid hydration mismatches, or causes significant delayed hydration/content layout shift compared to other client components.

After migrating to React 18, dynamically importing a language-specific component with React.lazy based on a zustand state variable causes the component to infinitely render/loading.

Hydration failed because the initial UI does not match what was rendered on the server. — I'm building a nextjs app with typescript and tailwind and also using shadcn components. Outcome: the entire root will switch to client rendering.

Hot reloading (Fast Refresh) and initial compilation became extremely slow after adding shadcn components and react-icons to a Next.js 14 + Tailwind project.

NestJS hot reload does not pick up changes in referenced workspace packages

Installation/build fails in a Next.js/React app with an error involving missing module 'react-dom/server.browser', alongside a runtime ReferenceError for `userouter` in `pages/login.js`.

Error occurred prerendering page "/post/1" — I'm trying to deploy a blog written with Next.js v15.3.3 with Vercel. Tension: TypeError: Cannot read properties of null (reading 'useState'). Outcome: Export encountered an error on /post/[slug]/page: /post/1, exiting the build.

In the Next.js app, the `wordGroups` state update works in `npm run dev` but does not trigger in production after `npm run build` and `npm run start`, so dependent `useEffect` hooks never run.

The browser shows a 'Module not found: react-refresh/runtime.js' error when running npm start, indicating the import path is being blocked as outside the project's src directory.

modules do run multiple times when imported in a Next.js application — in a Next.js application. Tension: No, imports do not only run once when the site is built, and never again. Outcome: At least every time a user lands on your website, an import happens client-side.

Some Next.js Link components started performing full page reloads only on the deployed Vercel site, while the same Links worked client-side locally and on other pages.

Running `eslint .` in a Next.js 16 app crashed immediately — The eslint.config.mjs used the long-standard Next.js pattern: `new FlatCompat({ baseDirectory })` + `compat.extends('next/core-web-vitals', 'next/typescript')`. Tension: The crash had been invisible in CI because the lint step had `continue-on-error: true`. Outcome: The job reported green while lint hadn't run for weeks.

Page changed from static to dynamic at runtime /story/0d3778b0-9e86-4b0a-a043-ed892f2417a0, reason: headers — compile a Next.js frontend on a Kubernetes pod. Outcome: at headers (/app/.next/server/chunks/827.js:26854:39).

Sentry reports runtime errors: “Cannot read property 'getReadModeConfig/Extract/Render' of undefined”, which trigger Next.js error handling and break the site during static page rendering.

work perfectly fine on my local machine but fail consistently when executed in GitHub Actions — My setup involves a Next.js 14 app using the App Router, TypeScript, Playwright for testing, and GitHub Actions for CI. Outcome: download an HTML report saved in the last step in your CI.

Next.js throws “WEBPACK_IMPORTED_MODULE is not a function” when a module exporting a hook is called from a non-client context. The error persists despite changing references.

Using `react-pdf` with Next.js 14.2 fails at runtime with an error stating that the `react-pdf.js` require in the server bundle must be changed to a dynamic `import()`. The app cannot load `@react-pdf/renderer` in the current build setup.

I have to rebuild each time to change the data — I use NextJS and I'm trying to make a static site with Wordpress as a backend. Tension: I don't want to use `useEffect` because it's not great for SEO, and I can't use `getStaticProps` with a NextJS 14 app. Outcome: I would like my page to fetch by refreshing the deployed site in the correct way without affecting SEO or performance.

the console is filled with: — I have an existing next.js codebase with multiple bugs that need fixing. Tension: Support for defaultProps will be removed from function components in a future major release. Outcome: How can I fix or suppress the warnings so I can read the console?

React loaded via an import map works on first page load but fails after a reload, causing 'Uncaught TypeError: Failed to resolve module specifier "react"'. Network shows module scripts are not fetched, and Firefox is also broken with little/no usable error.

CSS Modules generated hashed class names were present in the rendered HTML, but the corresponding CSS rules were missing in the browser, so styles were not applied. The issue occurred when setting up Rspack within an Nx React monorepo with SCSS and Module Federation.

Module parse failed: Unexpected token (5:19) — ERROR in ./node_modules/react-infinite-scroller/src/InfiniteScroll.js 5:19. Tension: You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. Outcome: Webpack needs to parse imported js files.

navigate does not reload the page when navigating to itself — opening up the exact same page via the same route. Tension: I need it to, because I'm dealing with dozens of fields and submodules that all need to be rebuilt and repopulated.

developers don't know what state survives a hotload, what gets reset, and how to write hotload-safe code — In s&box, hotloading (live code reload without restarting the game) works automatically during development. Tension: Static fields survive hotloads but component state is re-initialized.

throws "Cookies can only be modified in a Server Action or Route Handler" — called from Next.js 15 Server Components (pages, layouts). Tension: The error appears intermittently — only when the session needs refreshing (controlled by `updateAge` config). Outcome: With `updateAge: 300` (5 minutes), it crashes every ~5 minutes for active users.

Dev hot-reload silently stops working — Next.js (App Router) and a WebSocket server in the same Node process. Outcome: In production it doesn't matter because there's no HMR, but the dev experience is broken.
