Since we are so much focused on messaging layer, internationalisation and localisation is mission critical for us. We explored lots of solutions for incorporating messages for multiple languages but none of the solution worked out of box for us. After doing research, explored we need to zero down to one of the mentioned two options:
1: i18next
2: react-intl
Although both are complementary solutions with react-intl on first looked like eventual solution. But having different string messages for different languages looked like very hacky and react-intl was not infact made for that. Its mainly for localising formats (e.g., date). Also we are already using i18n on our API servers, so i18next looks like an apt choice for the workflow is similar. Here is how to integrate this i18next.
