vue-spinach

Popeye can save Olive with the power of spinach. So do Olive.

Transform Vue SFC between Option API and Composition API.

[!NOTE] This is NOT an official library of Vue.

[!TIP] Currently only the transformation from Option API to Composition API is supported.

Usage

CLI

pnpm dlx vue-spinach <inFile> [--print] [--out outFile] [--config configFile]

vue-spinach will read the file contents from process.stdin if inFile is not specified.

outFile defaults to the same as inFile, unless inFile is not specified or print is specified. Then it will be output via process.stdout.

configFile specifies an ES Module file with default exports. Refer to Options.

JS API

import type { TransformOptions } from 'vue-spinach'
import { transformSFC } from 'vue-spinach'

function transformSFC(code: string, userOptions?: Partial<TransformOptions>): string

import { transformSFC } from 'vue-spinach'

const code = transformSFC(`
<script>
export default {
  // ...
}
</script>
`, {
  reactivityTransform: true,
})
