Configuration file

Create nimpl-i18n.js file in the app root directory

const fs = require("fs/promises");
 
/** @type {import('@nimpl/i18n/configuration/types').Config} */
module.exports = {
    load: async (language) => {
        const data = await fs.readFile(`./translates/${language}.json`);
        const dictionary = JSON.parse(data);
        return dictionary;
    },
    getLanguage: async ({ params }) => params.language,
    languages: ['en', 'de', 'fr'],
};

Configure app

If you can transfer the package configuration file to the server in such a way that it remains readable - the instructions above will be enough.

However, if there is no way to transfer the file or the hosting has internal blocks (for example, Vercel considers this file unused and does not read it) - you need to wrap next.config.js in withI18n

const { default: i18n } = require('@nimpl/i18n/i18n');
 
const i18nWrapper = i18n();
 
/** @type {import('next').NextConfig} */
const nextConfig = {};
 
module.exports = i18nWrapper(nextConfig);
