Visual Studio Code (VSCode) is strongly recommended for its great out-of-the-box support for TypeScript. Vue CLI also provides TypeScript support, but is no longer recommended. You can run vue-tsc in watch mode in parallel to the Vite dev server, or use a Vite plugin like vite-plugin-checker which runs the checks in a separate worker thread. It works largely the same as tsc except that it supports Vue SFCs in addition to TypeScript files. vue-tsc is a wrapper around tsc, TypeScript's own command line interface. If using SFCs, use the vue-tsc utility for command line type checking and type declaration generation. This ensures the Vite dev server stays blazing fast even when using TypeScript.ĭuring development, we recommend relying on a good IDE setup for instant feedback on type errors. With a Vite-based setup, the dev server and the bundler are transpilation-only and do not perform any type-checking. Project Setup Ĭreate-vue, the official project scaffolding tool, offers the options to scaffold a Vite-powered, TypeScript-ready Vue project.
All official Vue packages come with bundled type declarations that should work out-of-the-box. Vue is written in TypeScript itself and provides first-class TypeScript support. TypeScript also improves developer ergonomics via type-based auto-completion in IDEs. This reduces the chance of runtime errors in production, and also allows us to more confidently refactor code in large-scale applications.
