- Examples
- Vue2 basic example
- using esm version
- A more complete API usage example
- Load a Vue component from a string
- Using another template language (pug)
- Using another style language (stylus)
- SFC style CSS variable injection (new edition)
- import style
- Minimalist Hello World example
- Use
options.loadModulehook - Dynamic component (using
:isSpecial Attribute) - Nested components
- Use SFC Custom Blocks for i18n
- Use Options.getResource() and process the files (nearly) like webpack does
- Load SVG dynamically (using
watch()) - Load SVG dynamically (using
async setup()and<Suspense>) - Use remote components
Try the examples locally
Since most browsers do not allow you to access local filesystem, you can start a small express server to run these examples.
Run the following commands to start a basic web server on port 8181:
npm install express # or yarn add express
node -e "require('express')().use(require('express').static(__dirname, {index:'index.html'})).listen(8181)"note:
In the following examples, for convenience, we just returns static content as file. In real world, you would probably use something like this :
...
async getFile(url) {
const res = await fetch(url);
if ( !res.ok ) {
throw Object.assign(new Error(res.statusText + ' ' + url), { res });
}
return {
getContentData: (asBinary) => asBinary ? res.arrayBuffer() : res.text(),
}
},
...note: Vue2 do not have the Vue.defineAsyncComponent() function. Here we mount the app when the main component is ready.
