This library aims to provide codegen helpers and data structure for Vue language plugin API v1.x that does not depend on Volar runtime.
|
||
|
|
|
||
|
|
## Why "Muggle"?
|
||
|
|
|
||
|
|
A better situation is Volar can use magic-string on the Vue plugin API, but currently can't do this easily.
|
||
|
|
|
||
|
|
This solution is just for Vue language plugin API v1.x and planned to be deprecate in v2.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
The example is base-on [magic-string readme](https://github.com/rich-harris/magic-string#usage).
|
||
|
|
|
||
|
|
```html
|
||
|
|
<script>problems = 99</script>
|
||
|
|
|
||
|
|
<more-script lang="js">console.log( answer )</more-script>
|
||
|
|
```
|
||
|
|
|
||
|
|
```ts
|
||
|
|
import {
|
||
|
|
toString,
|
||
|
|
replace,
|
||
|
|
} from 'muggle-string';
|
