Next.js server-side rendering encountered an issue with hydration

I'm currently facing issues while using the react-i18next dependency with next.js.

Within my _app.js file, I have the following code snippet:

if (!isServer) {
    init_i18n();
}

function MyApp({ Component, pageProps }) {
    // The presence of this if statement seems to be causing some issues!
    if (i18n.isInitialized) {
        return <Component {...pageProps} />;
    } else {
        return <></>;
    }
}

Initially, when my _app.js file did not include the if statement:

if (!isServer) {
    init_i18n();
}

function MyApp({ Component, pageProps }) {
    return <Component {...pageProps} />;
}

I encountered a different hydration error:

Warning: Text content did not match. Server: "navbar.dashboard" Client: "Dashboard"

Your assistance in resolving this issue would be greatly appreciated!

Answer №1

After making the switch from react-i18next to next-i18next, I no longer encounter any problems with hydration. Hopefully, this information proves useful to you!

Answer №2

The reason for the hydration problem might be due to a piece of code attempting to access the window object, which is not accessible on the server. To resolve this, consider relocating the relevant code inside the componentDidMount method or its functional component equivalent.
