tsc

vue-tsc

A command-line type checking tool for Vue, based on a tsc wrapper, enabling the TypeScript compiler to understand .vue files.

Installation

npm install vue-tsc typescript --save-dev

Requires TypeScript 5.0.0 or higher.

Usage

Type Checking

vue-tsc --noEmit

Generate Declaration Files

vue-tsc --declaration --emitDeclarationOnly

Configuration in package.json

{
  "scripts": {
    "type-check": "vue-tsc --noEmit",
    "build:types": "vue-tsc --declaration --emitDeclarationOnly"
  }
}

Supported File Types

vue-tsc automatically reads file types to process from vueCompilerOptions.extensions in tsconfig.json, defaulting to ['.vue'].

If vitePressExtensions or petiteVueExtensions are configured, those extensions will also be processed.

Differences from tsc

vue-tsc is a wrapper around tsc that:

1. Reads vueCompilerOptions from tsconfig.json
2. Creates a Vue language plugin to process .vue files
3. Transforms .vue files into TypeScript virtual code before passing them to tsc

All tsc command-line arguments can be used directly.

Programmatic Usage

import { run } from 'vue-tsc';

// Use the default tsc path
run();

// Specify a custom tsc path
run('/path/to/typescript/lib/tsc.js');
