Can react-i18next add namespace after init
user
Sure, I can definitely help with that question. **Short Answer:** You can add namespaces to `react-i18next` after initialization using the `setLanguage` function. However, it's recommended to initialize thenamespaces at the same time for clear namespace mappings. **Explanation:**

`react-i18next` allows for multiple namespaces to be used, and they must be specified on initialization. However, if you need to add a namespace after initializing, you can use the `setLanguage` function provided by `i18n` class. Here's a simple example code:

```js
import React from 'react';
import ReactI18n from 'react-i18n';

const messages = {
  en: {
    myNamespace: {
      hello: 'Hello World',
    },
  },
  fr: {
    myNamespace: {
      hello: 'Bonjour Monde',
    },
  },
};

const MyComponent = ({ language, myNamespace }) => {
  return (
    <ReactI18n.Provider language={language} messages={messages[language]}>
      <h1>{t('myNamespace.hello')}</h1>
    </ReactI18n.Provider>
  );
};

const handleInitialization = async () => {
  const { language } = await context.getUserInfo();
  context.setLanguage(language);
  // You can add here
  context.i18n.addResourceBundle('en', 'myNamespace', {
    hello: 'Hello World',
  });
};

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      language: '',
    };

    this.handleLanguageChange = ({ target: { value } }) =>
      this.setState({ language: value });
  }

  render() {
    return (
      <div>
        <select
          value={this.state.language}
          onChange={this.handleLanguageChange}
        >
          <option value="en">English</option>
          <option value="fr">French</option>
        </select>
        <MyComponent
          language={this.state.language}
          // you can dynamically change it
          myNamespace="myNamespace"
        />
        <button onClick={handleInitialization}>Initialize</button>
      </div>
    );
  }
}

export default App;
```

In this example, we added the `myNamespace` to the `en` language bundle after the initializing. Although, it's not recommended to add a namespace dynamically, you should initialize all the namespaces at the same time for maintained namespace mappings. I hope this helps you. Let me know if you have any further queries.

Can react-i18next add namespace after init

Yes, react-i18next allows you to add a namespace after initialization. You can use the `t` function (provided by react-i18next) with the `ns` option to switch to a different namespace at runtime.

Here's an example:

```javascript
import React from 'react';
import { useTranslation } from 'react-i18next';

function MyComponent() {
  const { t } = useTranslation();

  return (
    <div>
      {t('myKey', { ns: 'myNamespace' })}
    </div>
  );
}

export default MyComponent;
```

In this example, the `t` function will look for the key 'myKey' in the namespace 'myNamespace'. By default, if you don't provide a namespace, it will use the default namespace you set during initialization.

However, if you want to add a new namespace globally after initialization, you might need to manually handle merging the new namespace into your existing resources and then call `i18n.changeLanguage` to trigger a re-render of your components with the updated translations. This is not a typical use case, so it's not directly supported by react-i18next, but it can be done with some additional code.
