To use in browser, grab the [magic-string.umd.js](https://unpkg.com/magic-string/dist/magic-string.umd.js) file and add it to your page:
magic-string is ESM-only. In browsers, import it from an ESM CDN:
```html
<script src="magic-string.umd.js"></script>
<script type="module">
import MagicString from 'https://unpkg.com/magic-string/dist/index.mjs';
</script>
```
(It also works with various module systems, if you prefer that sort of thing - it has a dependency on [vlq](https://github.com/Rich-Harris/vlq).)
