@94ai/vue2-runtime-helpers v1.0.1

Introduction

High level utilities for compiling Vue2 single file components, runtime helpers for @94ai/vite-plugin-vue2 .

This package contains high level utilities that you can also use if you are writing a plugin / transform for a bundler or module system that compiles Vue single file components into JavaScript.
