The vue-tsc npm package is a TypeScript type checker for Vue.js applications. It is used to perform type checking on Vue single-file components (SFCs) and their associated TypeScript code. It works alongside Vite and Vue 3 to provide a development experience with type safety.
Type Checking for Vue SFCs
This command performs type checking on Vue single-file components without emitting any code. It is typically used in a build or CI pipeline to ensure type safety before deployment.
vue-tsc --noEmitType Checking with Code Emission
This command performs type checking and also emits the compiled JavaScript code to the specified directory. This can be used as part of a build process that requires the compiled output.
vue-tsc --outDir distThe TypeScript npm package is the core TypeScript compiler. It provides type checking and code compilation for TypeScript files. While it does not have built-in support for Vue SFCs, it is the underlying technology that vue-tsc leverages for type checking.
VLS (Vetur Language Server) is part of the Vetur extension for Visual Studio Code and provides language support for Vue.js. It includes features like syntax-highlighting, snippet generation, Emmet, linting/error checking, formatting, and auto-completion. It is similar to vue-tsc in that it provides type checking for Vue files, but it is more focused on the in-editor experience rather than being a standalone CLI tool.
Vetur is a Visual Studio Code extension that provides tooling for Vue.js development, including syntax highlighting, IntelliSense, linting, and formatting. It is similar to vue-tsc in that it helps with type checking and error detection in Vue SFCs, but it is specifically designed as an integrated development environment (IDE) extension rather than a command-line tool.
Vue 3 command line Type-Checking tool.
Type check:
vue-tsc --noEmit
Build dts:
vue-tsc --declaration --emitDeclarationOnly
