Hot Reloading not working in Next.js 9 using custom routing, styled components and withApollo example

The issue at hand revolves around a Next.js application not rerendering the page when changes are made to the application. Currently, the application is started in development mode using the command “cross-env NODE_ENV=development babel-node src/server.js” from the server.js file. Although the application successfully compiles when changes are made to the pages or components folder, the changes do not reflect on the page until the page is manually refreshed. This behavior disrupts the expected hot reloading functionality provided by Next.js during development.

To reproduce the issue, the following steps were taken: running the application, navigating to a page in a browser, making changes to the page, and observing that the compilation succeeds without triggering a rerender of the page. The expected behavior would be for Next.js to perform hot reloading and automatically reflect the changes on the page without the need for manual refreshing. However, this behavior is currently not being exhibited.

export const resolvers = {
    Mutation: {
        setGlobalVolume: (_, { volume }, { cache }) => {
            // cache.writeData({ data: { globalVolume: volume } });
            return null;
        },
        setGlobalSrc: (_, { id }, { cache }) => {
            // cache.writeData({ data: { globalSrcId: id } });
            return null;
        },
    },
};

While the experiences shared by the users shed light on the significance of meticulously checking file imports and references, it is important to note that their specific instances may not directly resolve the original issue at hand. However, their accounts emphasize the criticality of maintaining consistency in file naming conventions and ensuring accurate file paths. Development environments can be highly sensitive to even minor inconsistencies, and such discrepancies can lead to unexpected disruptions in functionality, including the failure of features like Fast Refresh. Therefore, developers should remain vigilant in their attention to detail when handling file imports and references to avoid potential issues.

In the case mentioned by one user, the problem arose from a mismatch in the casing of a folder reference within their application. The user had a folder named in all lowercase letters but was referencing it in a file with capitalized letters. Although the application successfully built and deployed, Fast Refresh and other refreshing mechanisms ceased to function until the casing was corrected to match. This demonstrates how seemingly insignificant inconsistencies can have significant impacts on the behavior of the application. To prevent similar issues, developers should carefully review their file imports and references, ensuring that the naming conventions and casing are consistent throughout the codebase.

While the shared experiences provide valuable insights, it is important to explore additional potential causes and solutions related to the specific issue faced. In addition to file import discrepancies, other factors may contribute to the failure of Fast Refresh or page rendering. Developers should consider factors such as configuration settings, dependencies, and build processes. Examining the development environment setup, verifying the compatibility of tools and libraries, and reviewing relevant documentation can help identify potential solutions. Furthermore, consulting the Next.js community, forums, or issue trackers might provide additional insights and guidance in resolving the issue at hand. By adopting a systematic and thorough approach to debugging and troubleshooting, developers can effectively address the problem and ensure a smooth development experience.
