Vue3 Single File Component loader.
Load .vue files dynamically at runtime from your html/js. No node.js environment, no (webpack) build step needed.
- Only requires Vue3 runtime
- Focuses on component compilation. Network, styles injection and cache are up to you (see example below)
- Embedded ES6 modules support ( including
import()) - Support custom CSS, HTML and Script language, see pug and stylus examples
- Properly reports template, style or script errors through the log callback
- You can build your own version and easily customize browsers you need to support

vue3-sfc-loader.js = Webpack( @vue/compiler-sfc + @babel )
- load the
.vuefile - parse and compile template, script and style sections (
@vue/compiler-sfc) - transpile script and compiled template to es5 (
@babel) - parse scripts for dependencies (
@babel/traverse) - recursively resolve dependencies
- merge all and return the component
