base64Encode<M extends MimeType>(
value: string,
mimeType: M,
): `data:${M};base64,${string}`

Type Parameters
- M extends MimeType
Parameters
- value: string
  UTF-8 string to encode.
- mimeType: M
  MIME type for the resulting data URI; SVG payloads are whitespace-minified first.
Returns `data:${M};base64,${string}`
A data:${mimeType};base64,... URI.
Example
```
base64Encode("hello", "text/plain"); // "data:text/plain;base64,aGVsbG8="
base64Encode("<svg> </svg>", "image/svg+xml"); // SVG whitespace minified before encoding
