Getting Started

1. Include

<!-- <link href="../src/assets/css/suneditor.css" rel="stylesheet"> -->
<!-- <link  href="../src/assets/css/suneditor-contents.css" rel="stylesheet"> -->
<link href="../dist/css/suneditor.min.css" rel="stylesheet">
<script src="../dist/suneditor.min.js"></script>
<script src="../src/lang/ko.js"></script>

2. Target Element

<textarea id="sample">Hi</textarea>

3. Create

/**
* ID : 'suneditor_sample'
* ClassName : 'sun-eidtor'
*/
// ID or DOM object
const suneditor = SUNEDITOR.create((document.getElementById('sample') || 'sample'),{
    // All of the plugins are loaded in the "window.SUNEDITOR" object in dist/suneditor.min.js file
    // Insert options
    // Language global object (default: en)
    lang: SUNEDITOR_LANG['ko']
});

4. Contents display

When you display a document created by suneditor
You need to include "src/assets/css/suneditor-contents.css" or "dist/css/suneditor.min.css" file.
Then add "sun-editor-editable" to the class name of the Tag element that displays the content.
In "suneditor-contents.css", you can define the style of all the tags created in suneditor.

Use import statement

1. Load only what you want

import 'suneditor/dist/css/suneditor.min.css'
import suneditor from 'suneditor'
import {font, fontSize, fontColor, horizontalRule, list, image} from 'suneditor/src/plugins'
// How to import language files (default: en)
import lang from 'suneditor/src/lang'
import {en, ko} from 'suneditor/src/lang'
import de from 'suneditor/src/lang/de'

suneditor.create('sample', {
    plugins: [
        font,
        fontSize,
        fontColor,
        horizontalRule,
        link,
        image,
    ],
    buttonList: [
        ['font', 'fontSize'],
        ['fontColor'],
        ['horizontalRule'],
        ['link', 'image']
    ],
    lang: lang.ko
});

2. Load all plugins

import 'suneditor/dist/css/suneditor.min.css'
import suneditor from 'suneditor'
import plugins from 'suneditor/src/plugins'

suneditor.create('sample', {
    plugins: plugins,
    buttonList: [
        ['undo', 'redo'],
        ['font', 'fontSize', 'formatBlock'],
        ['bold', 'underline', 'italic', 'strike', 'subscript', 'superscript'],
        ['removeFormat'],
        '/', // Line break
        ['fontColor', 'hiliteColor'],
        ['outdent', 'indent'],
        ['align', 'horizontalRule', 'list', 'table'],
        ['link', 'image', 'video'],
        ['fullScreen', 'showBlocks', 'codeView'],
        ['preview', 'print'],
        ['save', 'template']
    ]
})

// You can also load what you want
suneditor.create('sample', {
    plugins: [
        plugins.font
        plugins.fontSize
    ],
    buttonList: [
        ['font', 'fontSize'],
        // Plugins can be used directly in the button list
        [plugins.formatBlock]
    ]
})

3. Plugins can be used directly in the button list

import 'suneditor/dist/css/suneditor.min.css'
import suneditor from 'suneditor'
import {align, font, fontSize, fontColor, hiliteColor, horizontalRule,
        list, table, template, formatBlock, link, image, video} from 'suneditor/src/plugins'

suneditor.create('sample', {
    buttonList: [
        ['undo', 'redo'],
        [font, fontSize, formatBlock],
        ['bold', 'underline', 'italic', 'strike', 'subscript', 'superscript'],
        ['removeFormat'],
        [fontColor, hiliteColor],
        ['outdent', 'indent'],
        [align, horizontalRule, list, table],
        [link, image, video],
        ['fullScreen', 'showBlocks', 'codeView'],
        ['preview', 'print'],
        ['save', template]
    ],
})

Init function

The init function can be used by predefining options and calling the create function on the returned object.
The value of the option argument put in the "create" function call takes precedence

import 'suneditor/dist/css/suneditor.min.css'
import suneditor from 'suneditor'
import plugins from 'suneditor/src/plugins'

// all plugins
const initEditor = suneditor.init({
    plugins: plugins,
    height: 200,
    buttonList: [
        ['undo', 'redo',
        'font', 'fontSize', 'formatBlock',
        'bold', 'underline', 'italic', 'strike', 'subscript', 'superscript',
        'removeFormat',
        'fontColor', 'hiliteColor',
        'outdent', 'indent',
        'align', 'horizontalRule', 'list', 'table',
        'link', 'image', 'video',
        'fullScreen', 'showBlocks', 'codeView',
        'preview', 'print', 'save', 'template']
    ]
});

initEditor.create('sample_1', {
    // The value of the option argument put in the "create" function call takes precedence
});

initEditor.create('sample_2', {
    // The value of the option argument put in the "create" function call takes precedence
    height: 'auto',
    buttonList: [
        ['bold', 'underline', 'italic'],
        ['removeFormat'],
        ['preview', 'print']
    ]
});
