Vue 3 SFC
Vue.js, The Progressive JavaScript Framework, is an approachable, performant and versatile framework for building web user interfaces.
This is the documentation for LiveCodes language support for Vue Single-File Component (SFC). The support for Vue 2 SFC is documented separately.
Usage
Vue SFC can be used as documented in the specs, including support for Scoped CSS, CSS Modules, pre-processors, JSX and src
imports. See below for usage.
Demo
Scoped CSS
When a
<style>
tag has the scoped attribute, its CSS will apply to elements of the current component only.— docs
CSS Modules
A
<style module>
tag is compiled as CSS Modules and exposes the resulting CSS classes to the component as an object under the key of$style
.— docs
CSS Frameworks
CSS Frameworks supported in LiveCodes (e.g. Tailwind CSS, UnoCSS, WindiCSS) can detect class names added in Vue SFCs. Make sure that the required utility is enabled (from style editor menu or in processors
property of configuration object) and that required directives are added to the style editor.
See example below.
Languages and Pre-Processors
Blocks can declare pre-processor languages using the
lang
attribute.— docs
Many of the languages supported in LiveCodes can be used. The value of lang
attribute can be the language name (specified in its documentation page) or any of its aliases (extensions).
JSX
JSX can be used in render functions without needing any configuration.
src
Imports
The src attribute can be used to import an external file for a language block:
<template src="https://my-website.com/template.html"></template>
<style src="https://my-website.com/style.css"></style>
<script src="https://my-website.com/script.js"></script>
The value of src
attribute can be either:
- Absolute URL (e.g.
https://unpkg.com/todomvc-app-css/index.css
) - Path in npm package (e.g.
todomvc-app-css/index.css
)
Relative paths (e.g. ./my-styles.css
) cannot be used (because there is no file system in LiveCodes).
The imported sources can use any of the supported languages/pre-processors (identified by the file extension or can be specified by lang
attribute).
Module Imports
npm modules can be imported as described in the section about module resolution, including bare module imports and importing from different CDNs. Stylesheets imported in the script
block are added as <link rel="stylesheet">
tags in the page head
.
Example:
Module imports can be customized using import maps as described in module resolution documentations.
Importing Vue SFCs
Other Vue SFCs can be imported. The import URL has to be an absolute URL ending with .vue
extension. Any bare or relative imports in the imported files are resolved and compiled recursively.
This is an example of importing a Vue SFC, which in turn imports other Vue SFCs (the imported components use Tailwind CSS, which is enabled in this project as a CSS preprocessor):
- view source on GitHubPlease note that extensionless imports are not supported. However, you may customize the import URL using import maps as described in module resolution section.
This is an example of importing a Vue SFC, which in turn imports other Vue SFCs and extensionless imports, that are customized using importmap:
{
"imports": {
"https://raw.githubusercontent.com/hatemhosny/vue3-samples/master/src/composable/useTodoList": "https://raw.githubusercontent.com/hatemhosny/vue3-samples/master/src/composable/useTodoList.js",
"https://raw.githubusercontent.com/hatemhosny/vue3-samples/master/src/composable/useMousePosition": "https://raw.githubusercontent.com/hatemhosny/vue3-samples/master/src/composable/useMousePosition.js"
}
}
Root Element
To mount the application instance to a specific DOM element use "livecodes-app"
as the element id
. Otherwise, if that element is not found, a new div
element is added to document.body
and is used to mount the instance.
