RuntimeTranslationOptions
API Reference for the RuntimeTranslationOptions type
Overview
The RuntimeTranslationOptions type is used to pass variables to inline translations and specify their render behavior.
You can also add a locale to specify a different language for the translation.
This is used with the tx function.
Runtime Translation:
To translate a variable on demand, include them directly in the string passed to tx.
Variables passed to tx via the options object are not translated.

Description
| Prop | Description | 
|---|---|
| variables | An object where the keys identify where each value is mapped to in the string. | 
| $locale | Optionally include $localeas a variable in thevariablesobject to specify a locale for the translation. Will default to browser's most preferred locale that is supported by your app. | 
Examples
Passing variables
In order to add a variable to the string, we use the {variable-name} syntax, where curleybraces wrap the name of the variable.
import { tx } from 'gt-next/server';
const Component = () => {
  return <div>
    {tx(`Hello, {username}!`,{ username: 'Brian123' })}
  </div>;
};Using ICU message format
gt-next supports ICU message format, which allows you to also format your variables.
import { tx } from 'gt-next/server';
const Component = () => {
  return <div>
    { tx(
      'Your account balance: {dollars, number, ::currency/USD}!',
      {
        "dollars" : 1000000,
      }
    ) }
  </div>;
};Translating variables
In order to translate a variable, include it directly in the string passed to tx.
import { tx } from 'gt-next/server';
const Component = ({ hairColor }: { hairColor: string }) => {
  return <div>{tx(
    `Hello, {username}! Your haircolor is ${hairColor}`,
    { username: 'Brian123' }
  )}</div>;
};Note that the variable hairColor gets translated, but username does not.
Specifying a locale
You can specify a locale to use for the translation.
import { tx } from 'gt-next/server';
const Component = () => {
  return <div>{tx('Hello, world!', { $locale: 'fr' })}</div>;
};This will always be translated to french.
Notes
- RuntimeTranslationOptionsis used for string translations at runtime.
- The variablesobject passes values to the text.
- The variablesOptionsobject defines the behavior of the variables.
