vue-codemirror-component v1.1.1

Why need code splitting?

codemirror itself is a very powerful package that does not bundle into a single file when it's released. This is also because many users are most likely to load only some of them, loading all at once is not elegant enough. so that we can combine the dynamic import feature of webpack2+ to achieve the goal of reducing the size effectively.

Quick Start

As above mentioned, to use this component, you need to use webpack2 and above version.

1. Install webpack, css-loader and style-loader.

   npm i install webpack -D

2. Config in webpack.config.js:

   module.exports = {
     module: {
       rules: [
         {
           test: /\.css$/,
           use: [ 'style-loader', 'css-loader' ]
         }
       ]
     }
   }

Then, show you the usage code:

If you want to register vue-codemirror as a global component, you can use:

import VueCodemirror from 'vue-codemirror-component'
Vue.use(VueCodemirror, options)

Or if you don't want to pollute the global scope, you can register it when you want to use it:

  import { createComponent } from 'vue-codemirror-component'
  export default {
    name: 'app',
    components: {
      'vue-codemirror': createComponent(options)
    }
  }  

API

Default export

default export is the install function for this component.

import VueCodemirror from 'vue-codemirror-component'
Vue.use(VueCodemirror, options)

options.loadTheme

• Type: (theme: string): Promise<void>

• Required: true

  Runs when the editor's theme changes, you can use the import() syntax, and also supports a third-party asynchronous load library.

  loadTheme(theme) {
    return import('codemirror/theme/' + theme + '.css')
  }

options.loadMode

• Type: (mode: string): Promise<void>

• Required: true

  Runs when the editor's mode changes, the usage is same to options.loadTheme.

  loadTheme(theme) {
    return import('codemirror/theme/' + theme + '.css')
  }

Example

A full usage example as follows:

<template>
  <div class="simple-editor">
    <div class="editor">
      <vue-codemirror v-model="code" :options="editorOpts"></vue-codemirror>
    </div>
    <div class="preview">
      <pre v-html="code"></pre>
    </div>
  </div>
</template>

<script>
  import { createComponent } from 'vue-codemirror-component'
  
  const vueCodemiiror = createComponent({
    loadTheme(theme) {
      return import('codemirror/theme/' + theme + '.css')
    },
    loadMode(mode) {
      return import('codemirror/mode/' + mode + '/' + mode + '.js')
    }
  })  


  export default {
    components: {
      vueCodemiiror
    },
    data () {
      return {
        code: '<h1>V-Codemirror</h1>',
        editorOpts: {
          mode: 'text/html'
        },
      }
    }
  }
