According to the Vue roadmap, Vue 2 will only get one more minor release as an LTS version, supported for 18 months. This was back in September 2020, which means that a lot of Vue 2 projects will either have to switch to the migration build or to Vue 3 to ensure an up-to-date frontend framework. Since it is a major upgrade, Vue 3 comes with breaking changes. First of all, Vue provides a migration build that should help with the transition to Vue 3, as it is compatible with Vue 2 while providing Vue 3 support.

Vue.js is a popular JavaScript framework which recently surpassed React in stars on GitHub. And TypeScript is getting more popular as well. So, combining the two is a likely choice for a new web app project. Our team made the same decision but soon found out that the Vue ecosystem and TypeScript are not a perfect match. Vue itself has a decent TypeScript support nowadays and will even be re-written in TypeScript for its next major version.
