$ yarn add react-html-i18n

$ npm install react-html-i18n

No other translation library (that I’m aware of) supports both HTML and React elements in the same message.

Some libraries support custom tags, like this:

Hello, <tag>{name}</tag>.

However, it’s not really HTML, as translators can’t add attributes, and each tag must have its behavior defined by the programmer. If you only need basic rich text features like bold and italics, that might be good enough. But what if the translator wants to control the href of a link, or add inline style to an element?

If you have an existing collection of translation strings containing HTML, you’re out of luck with most i18n libraries. At best, the ones that support HTML (like old versions of react-intl) only allow substitution of primitive values. This library supports substitution of any value that React can render – including React elements!
