vue-class-clsx v0.1.3

vue-class-clsx

A plugin that supports writing class modules in vuejs quickly and easily similar to classname and clsx for reactjs

Note that the plugin does not support vue2

Demo

Install

npm install vue-class-clsx -D
yarn add vue-class-clsx -D

Setup

1. Import with global

   import { createApp } from 'vue';
   import { createVClsx } from 'vue-class-clsx'; // import vclsx
   import App from './App.vue';
   
   const app = createApp(App);
   const vclsx = createVClsx();
   
   app.use(vclsx); // use vclsx
   app.mount('#app');

2. Import with component

   import { vclsxComponent as vclsx } from 'vue-class-clsx'

3. Use with typescript

   Add to env.d.ts

   import type { createVClsx } from 'vue-class-clsx';
   
   declare module '@vue/runtime-core' {
     interface ComponentCustomProperties {
       vclsx: createVClsx;
     }
   }

Usage

Use with function vclsx

<template>
  <h2 :class="vclsx('title')">Hello</h2>
</template>
<style module>
  .title {
    color: green;
  }
</style>

Use with v-binding

<template>
  <h2 v-class-module="'title'">Hello</h2>
  <h2 v-class-module="['title', 'primay']">Hello</h2>
</template>
<style module>
  .title {
    color: green;
  }

  .primay {
    color: tomato;
  }
</style>

Options (new)

1. Custom css module name

if you set custom module name for class name, then use below option. Note the option only works when used with global

<style module="custom-name"></style>

const vclsx = createVclsx({ cssModuleName: 'custom-name' });

2. Custom function name

const vclsx = createVclsx({ functionName: 'vx' });

<template>
  <h2 :class="vx('title')">Hello</h2>
</template>

Warning Attention: If you customize the function name, you need to update the type declaration to avoid construction errors

// Add to env.d.ts
import type { createVClsx } from 'vue-class-clsx';

declare module '@vue/runtime-core' {
  interface ComponentCustomProperties {
    vx: createVClsx; // vclsx => vx
  }
}

3. Custom v-binding name

const vclsx = createVclsx({ directiveName: 'v-vx' });

<template>
  <h2 v-vx="'title'">Hello</h2>
  <h2 v-vx="['title', 'primay']">Hello</h2>
</template>

Example

Note: plugin only works with components that use css module

<style module></style>

<script setup lang="ts">
  import { ref } from 'vue';

  const bg = ref(false);
  const italic = ref(true);
  const green = ref(true);
</script>

<template>
  <!-- use with v-binding -->
  <h1>Use with v-binding</h1>

  <h2 v-class-module="{ t1: green, t2: bg, t3: italic }">Hello world! (button change)</h2>
  <h2 v-class-module="'t1'">Hello world!</h2>
  <h2 v-class-module="['t1', 't2']">Hello world!</h2>
  <h2 v-class-module="['t1', 't2', { t3: true }]">Hello world!</h2>
  <h2 v-class-module="['t1', 't2', ['fs', { t3: true }]]">Hello world!</h2>

  <hr />
  <!-- use with function -->
  <h1>Use with :class function</h1>
  <h2 :class="vclsx({ t1: green, t2: bg, t3: italic })">Hello world! (button change)</h2>
  <h2 :class="vclsx('t1', 't2')">Hello world!</h2>
  <h2 :class="vclsx(['t1', 't2'])">Hello world!</h2>
  <h2 :class="vclsx(['t1', 't2', { t3: true }])">Hello world!</h2>
  <h2 :class="vclsx(['t1', 't2', ['fs', { t3: true }]])">Hello world!</h2>
  <hr />
  <button v-class-module="{ active: bg }" @click="bg = !bg">background</button>
  <button v-class-module="{ active: italic }" @click="italic = !italic">Italic</button>
  <button v-class-module="{ active: green }" @click="green = !green">Green</button>
</template>
<style module>
  * {
    font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell,
      'Open Sans', 'Helvetica Neue', sans-serif;
  }

  button {
    color: #333;
    margin-right: 4px;
  }

  .active {
    background: #333;
    color: #fff;
  }

  .fs {
    font-size: 3rem;
  }

  .t1 {
    color: green;
  }

  .t2 {
    background: yellow;
  }

  .t3 {
    font-style: italic;
  }
</style>

// string
vclsx('class1', 'class2', 'class3');
//=> class1 class2 class3

// array
vclsx(['class1', 'class2', 'class3']);
//=> class1 class2 class3

// object
vclsx({ class1: true, class2: false });
//=> class1

// string, object, array
vclsx('class1', { class2: true, class3: false }, ['class4', { class5: true }]);
//=> class1 class2 class4 class5

Input

The vclsx function can take multiple arguments of type arrays, strings, and objects

Priority

When using v-binding and function at the same time to call the css class module, the class generated from: class (function) is always called last

Example

<template>
  <h2 :class="vclsx('primary')" v-class-module="'title'">Hello</h2>
</template>
<style module>
.title {
  color: green;
}

.primary {
  color: tomato;
}

<!-- result -->
<h2 class="_title_bbnon_3 _primary_bbnon_11">Hello</h2>
