# disable-ts-in-templates
2+
3+
This template should help get you started developing with Vue 3 in Vite.
4+
5+
## Recommended IDE Setup
6+
7+
[VSCode](https://code.visualstudio.com/) + [Volar](https://marketplace.visualstudio.com/items?itemName=Vue.volar) (and disable Vetur).
8+
9+
## Type Support for `.vue` Imports in TS
10+
11+
TypeScript cannot handle type information for `.vue` imports by default, so we replace the `tsc` CLI with `vue-tsc` for type checking. In editors, we need [Volar](https://marketplace.visualstudio.com/items?itemName=Vue.volar) to make the TypeScript language service aware of `.vue` types.
12+
13+
## Customize configuration
14+
15+
See [Vite Configuration Reference](https://vitejs.dev/config/).
16+
17+
## Project Setup
18+
19+
```sh
20+
npm install
21+
```
22+
23+
### Compile and Hot-Reload for Development
24+
25+
```sh
26+
npm run dev
27+
```
28+
29+
### Type-Check, Compile and Minify for Production
30+
31+
```sh
32+
npm run build
33+
```
34+
35+
### Lint with [ESLint](https://eslint.org/)
36+
37+
```sh
38+
npm run lint
39+
```
