fela-vue
Fela mixin for Vue designed for flexibility yet team-oriented. website.
(tree-shaking friendly!)
Fela does the great job, but it has no idea how to cook it with Vue. This is what I've created after combining vue's :style and :class attributes to make apps dynamically configured and easiest to write and maintain.
Included as deps:
The plugins are a lite most useful part of fela-preset-web.
USAGE
More about plugins. Several basic are already built in here!
More about enhancers. I suggest to look at this one first to have nice-looking classes during development.
Usage with literal css (lit-css) from this package
In the options object below you can also add other Renderer options
// All of the options are optional.const options = // Default styles to mix. Does not mix if omitted. // Have a look at the example below to see it in action. // Either pass a function (then key would be `fdef`): colors: cyan: 'cyan' // ... Or an object with your own key: defStyles: key: 'fdef' colors: cyan: 'cyan' // Name of styling method. Defaults to `f`. method: 'f' // Additional fela plugins. plugins: // Additional fela enhancers. enhancers: // Preset configurations. preset: // Config for fela-plugin-unit. Same defaults ('px', {}). unit: 'em' margin: '%' // SSR status. ssr: false const renderer = options // Use globallyVue// ... Or per module mixins: renderermixin // ...EXAMPLES
** same options object as above **
WITHOUT SSR
main.js
VueWITH SSR
entry.server.js is the same as entry.client.js
// OR const { Renderer } = require('fela-vue') const renderer = ...options // SSR status to `true`. ssr: true VueThen just put renderer.style into your template.
Component example
MyComponent.vue
<template> <div :class="f('wrapper')"> <span :class="f('one')"> It's green! </span> <span :class="f('two')"> It's cyan! </span> <span :class="f('three', {color: 'white'})"> you don't see me! </span> <span :class="f({color: 'yellow'})"> I do it by myself! </span> <span :class="f('one two, bold')"> Combined classes by commas and spaces </span> <span :class="f('bold my-kebab')"> And kebab-case! </span> <span :class="f('bold myKebab')"> The same! </span> <span :class="f('button one')"> If class is not in local style(), it will be taken from defaults (defStyles), if present. Here's button could be taken from there, then merged with `one` where is `one` is in priority: right to left principle. </span> <div v-for="i in [0,1,2]"> <span :class="f((i) => ({color: ['green', 'blue', 'yellow'][i]}))" > This way is OK too. </span> </div> </div></template> <script>// Uncomment to use literal css: css`...`// import { css } from 'fela-vue' export default { computed: { style() { // Or any other key in `options.defStyles.key`. const { colors } = this.fdef // Also, it's OK to return one css`...` with all classes included. return { one: { color: 'green' }, two: { color: colors.cyan }, three: ({color}) => { fontWeight: 'bold', color }, bold: () => ({ fontWeight: 'bold' }), // 'my-kebab' is also valid if the same in the template. myKebab: { color: 'purple' }, anotherClass: css` background: grey `, ...css` .other-class { margin-top: 44; // still ok for fela. will be 44px. // you can comment a whole line, margin-left: 22 // this's OK too. /* block comments are also supported. */ :hover { // no colons and semicolons are ok. background grey } } .anotherOne { padding: 15 } ` } } }}</script>It's better to make this computed in the end of a component definition or make a const variable at the bottom and return it from the computed prop.
Also, It's very handy to make snippets for adding style() {} to computed.
