Dev-mode: reload resources on page reload

Is your feature request related to a problem? Please describe.

When you develop the app u are usually adding / changing keys in the translation jsons, because of the fact that i18n runs once (at server startup) the change is not reflected in the browser, you need to restart the server for the changes to affect.

Describe the solution you’d like

We can add in the next-i18next middleware a check for NODE_ENV=development and if so, attach additional middleware that will invoke i18n.reloadResources.

I’ve developed i18next-hmr in-order to hot reload client & server when translations are changes… check it out :]

So, I agree with u that it should not be part of this lib.

If anyone interested with my final solution:

const chokidar = require('chokidar');
const path = require('path');
chokidar.watch('static/locales/**/*.json', { ignoreInitial: true }).on('all', (_event, filePath) => {
    const parsedPath = path.parse(filePath);
    const ns = parsedPath.name;
    const lng = path.basename(parsedPath.dir);
    nextI18next.i18n.reloadResources([lng], [ns]);
    console.log(chalk.magenta(`\nReloaded successfully ${filePath}`));
});
