  • Vue.js

    🖖 Vue.js is a progressive, incrementally-adoptable JavaScript framework for building UI on the web.

    Since Vue.js is an approachable, performant and versatile framework for building web user interfaces, it also needs a best-in-class internationalization solution. You may know vue-i18n, but for those already knowing i18next a Vue.js adapted version of i18next would be more appropriate.
