Why Internationalize Your React Application?

This capability enhances user experience and broadens your application's reach by making it more accessible and relevant to people from different linguistic backgrounds.

Why to integrate Intlayer?

• JavaScript-Powered Content Management: Harness the flexibility of JavaScript to define and manage your content efficiently.
• Type-Safe Environment: Leverage TypeScript to ensure all your content definitions are precise and error-free.
• Integrated Content Files: Keep your translations close to their respective components, enhancing maintainability and clarity.

Installation

Install the necessary package using your preferred package manager:

npm install react-intlayer

yarn add react-intlayer

pnpm add react-intlayer

Example of usage

With Intlayer, you can declare your content in a structured way anywhere in your codebase.

By default, Intlayer scans for files with the extension .content.{json,ts,tsx,js,jsx,mjs,mjx,cjs,cjx}.

You can modify the default extension by setting the contentDir property in the configuration file.

Declare your content

react-intlayer is made to work with the intlayer package.intlayer is a package that allows you to declare your content anywhere in your code. It converts multilingual content declarations into structured dictionaries that integrate seamlessly into your application.

Here’s an example of content declaration:

import { t, type Dictionary } from "intlayer";

const component1Content = {
  key: "component-1",
  content: {
    myTranslatedContent: t({
      en: "Hello World",
      fr: "Bonjour le monde",
      es: "Hola Mundo",
    }),
    numberOfCar: enu({
      "<-1": "Less than minus one car",
      "-1": "Minus one car",
      "0": "No cars",
      "1": "One car",
      ">5": "Some cars",
      ">19": "Many cars",
    }),
  },
} satisfies Dictionary;

export default component1Content;

Utilize Content in Your Code

Once you have declared your content, you can use it in your code. Here's an example of how to use the content in a React component:

"use client";

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

export const Component1Example: FC = () => {
  const { myTranslatedContent } = useIntlayer("component-1"); // Create related content declaration

  return (
    <div>
      <p>{myTranslatedContent}</p>
    </div>
  );
};

"use client";

import { useIntlayer } from "react-intlayer";

const Component1Example = () => {
  const { myTranslatedContent } = useIntlayer("component-1"); // Create related content declaration

  return (
    <div>
      <p>{myTranslatedContent}</p>
    </div>
  );
};

"use client";

const { useIntlayer } = require("react-intlayer");

const Component1Example = () => {
  const { myTranslatedContent } = useIntlayer("component-1"); // Create related content declaration

  return (
    <div>
      <p>{myTranslatedContent}</p>
    </div>
  );
};
