Next.js Integration: useIntlayer Hook Documentation

The useIntlayer hook is tailored for Next.js applications to fetch and manage localized content efficiently. This documentation will focus on how to utilize the hook within Next.js projects, ensuring proper localization practices.

Importing useIntlayer in Next.js

Depending on whether you're working on client-side or server-side components in a Next.js application, you can import the useIntlayer hook as follows:

• Client Component:

  typescript

  Copy content

  Copy code

  Copy the code to the clipboard

  import { useIntlayer } from "next-intlayer"; // Used in client-side components

• Server Component:

  tsx

  Copy content

  Copy code

  Copy the code to the clipboard

  import { useIntlayer } from "next-intlayer/server"; // Used in server-side components

Parameters

1. key: A string identifier for the dictionary key from which you want to retrieve content.
2. locale (optional): A specific locale to use. If omitted, the hook defaults to the locale set in the client or server context.

Dictionary Files

It's crucial that all content keys are defined within content declaration files to prevent runtime errors and ensure type safety. This approach also facilitates TypeScript integration for compile-time validation.

Instructions for setting up content declaration files are available here.

Example Usage in Next.js

Here's how you can implement the useIntlayer hook within a Next.js page to dynamically load localized content based on the application's current locale:

import { ClientComponentExample } from "@components/ClientComponentExample";
import { ServerComponentExample } from "@components/ServerComponentExample";
import { type NextPageIntlayer, IntlayerClientProvider } from "next-intlayer";
import { useIntlayer, IntlayerServerProvider } from "next-intlayer/server";

const HomePage: NextPageIntlayer = async ({ params }) => {
  const { locale } = await params;

  const content = useIntlayer("homepage", locale);

  return (
    <>
      <p>{content.introduction}</p>
      <IntlayerClientProvider locale={locale}>
        <ClientComponentExample />
      </IntlayerClientProvider>
      <IntlayerServerProvider locale={locale}>
        <ServerComponentExample />
      </IntlayerServerProvider>
    </>
  );
};

"use-client";

import type { FC } from "react";
import { useIntlayer } from "next-intlayer";

const ClientComponentExample: FC = () => {
  const content = useIntlayer("component-content");

  return (
    <div>
      <h1>{content.title}</h1>
      <p>{content.description}</p>
    </div>
  );
};

import type { FC } from "react";
import { useIntlayer } from "next-intlayer/server";

const ServerComponentExample: FC = () => {
  const content = useIntlayer("component-content");

  return (
    <div>
      <h1>{content.title}</h1>
      <p>{content.description}</p>
    </div>
  );
};

Handling Attribute Localization

To localize attributes such as alt, title, href, aria-label, etc., ensure you reference the content correctly:

<img src={content.image.src.value} alt={content.image.alt.value} /><img src={content.image.src.toString()} alt={content.image.alt.toString()} /><img src={String(content.image.src)} alt={String(content.image.alt)} />
