用Vue+TypeScript项目配置实战

vue create vue-typescript
// 在此选择typescript支持
? Check the features needed for your project: () Babel () TypeScript ( ) Progressive Web App (PWA) Support () Router () Vuex >() CSS Pre-processors () Linter / Formatter ( ) Unit Testing ( ) E2E Testing 我是08年出道的高级前端架构师，有问题或者交流经验可以进我的扣扣裙 519293536 我都会尽力帮大家哦

// 引入 vue-class-component 插件 // 以下大概是我的选择 ? Use class-style component syntax? (Y/n) y ? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)? Yes ? Use history mode for router? (Requires proper server setup for index fallback in production) Yes ? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported by default): Sass/SCSS (with node-sass) ? Pick a linter / formatter config: Prettier ? Pick additional lint features: Lint on save ? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated config files ? Save this as a preset for future projects? (y/N) n
