Quick start
CKEditor 5 is a powerful, rich text editor you can embed in your web application. This guide will show you the fastest way to start using it.
You have a few methods to choose from:
- Using CKEditor 5 Builder for the smoothest setup with live preview and multiple integration options.
- Using npm, where you use a JavaScript package and build the editor with a bundler.
- Using CDN, where you use our cloud-distributed CDN in a no-build setup.
- Using a ZIP file, where you download the ready-to-run files and copy them to your project.
- Choosing one of the pre-made integrations with popular frameworks (see table of contents for details).
# Using CKEditor 5 Builder
Check out our interactive Builder to quickly get a taste of CKEditor 5. It offers an easy-to-use user interface to help you configure, preview, and download the editor suited to your needs. You can easily select:
- editor type,
- the features you need,
- the preferred framework (React, Angular, Vue or Vanilla JS),
- the preferred distribution method.
You get ready-to-use code tailored to your needs!
# Installing CKEditor 5 using npm
First, install the necessary package. The command below will install the main CKEditor 5 package containing all open-source plugins.
npm install ckeditor5
Now, you can import all the modules from the ckeditor5
package. Additionally, you have to import CSS styles separately. Please note the Essentials
plugin, including all essential editing features.
Importing and registering UI translations is optional for American English. To use the editor in any other language, use imported translations, as shown in the setup section.
import { ClassicEditor, Essentials, Bold, Italic, Font, Paragraph } from 'ckeditor5';
import 'ckeditor5/ckeditor5.css';
ClassicEditor
.create( document.querySelector( '#editor' ), {
plugins: [ Essentials, Bold, Italic, Font, Paragraph ],
toolbar: {
items: [
'undo', 'redo', '|', 'bold', 'italic', '|',
'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor'
]
}
} )
.then( /* ... */ )
.catch( /* ... */ );
Pass the imported plugins inside the configuration to the create()
method and add toolbar items where applicable.
The first argument in the create()
function is a DOM element for the editor placement, so you need to add it to your HTML page.
<div id="editor">
<p>Hello from CKEditor 5!</p>
</div>
That is all the code you need to see a bare-bone editor running in your web browser.
# Installing CKEditor 5 from CDN
CDN is an alternative method of running CKEditor 5. You can start using it in just a few steps and with a few tags.
Start by attaching a link to style sheets. They contain all styles for the editor’s UI and content. You can also include your styles if you like. Refer to the content styles guide for more information.
<link rel="stylesheet" href="https://cdn.ckeditor.com/ckeditor5/42.0.2/ckeditor5.css" />
Then, you need to attach the script with the JavaScript code. To simplify imports, you can use the feature available in browsers – the import map. It allows us to map an easy-to-remember specifier (like ckeditor5
) to the full URL of the file from the CDN. We use this browser feature to share an editor engine code between plugins.
<script type="importmap">
{
"imports": {
"ckeditor5": "https://cdn.ckeditor.com/ckeditor5/42.0.2/ckeditor5.js",
"ckeditor5/": "https://cdn.ckeditor.com/ckeditor5/42.0.2/"
}
}
</script>
Once you have added the import map, you can access the editor and its plugins using the ckeditor5
specifier.
You must run your code on a local server to use import maps. Opening the HTML file directly in your browser will trigger security rules. These rules (CORS policy) ensure loading modules from the same source. Therefore, set up a local server, like nginx
, caddy
, http-server
, to serve your files over HTTP or HTTPS.
In the following script tag, import the desired plugins, add them to the plugins
array, and add toolbar items where applicable. Note that both script tags (this and previous) have the appropriate type
values.
<script type="module">
import {
ClassicEditor,
Essentials,
Bold,
Italic,
Font,
Paragraph
} from 'ckeditor5';
ClassicEditor
.create( document.querySelector( '#editor' ), {
plugins: [ Essentials, Bold, Italic, Font, Paragraph ],
toolbar: {
items: [
'undo', 'redo', '|', 'bold', 'italic', '|',
'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor'
]
}
} )
.then( /* ... */ )
.catch( /* ... */ );
</script>
Lastly, add a tag for the editor to attach to.
<div id="editor">
<p>Hello from CKEditor 5!</p>
</div>
Your final page should look similar to the one below.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>CKEditor 5 - Quick start CDN</title>
<link rel="stylesheet" href="https://cdn.ckeditor.com/ckeditor5/42.0.2/ckeditor5.css" />
</head>
<body>
<div id="editor">
<p>Hello from CKEditor 5!</p>
</div>
<script type="importmap">
{
"imports": {
"ckeditor5": "https://cdn.ckeditor.com/ckeditor5/42.0.2/ckeditor5.js",
"ckeditor5/": "https://cdn.ckeditor.com/ckeditor5/42.0.2/"
}
}
</script>
<script type="module">
import {
ClassicEditor,
Essentials,

Font,
Paragraph
} from 'ckeditor5';
ClassicEditor
.create( document.querySelector( '#editor' ), {
plugins: [ Essentials, Bold, Italic, Font, Paragraph ],
toolbar: {
items: [
'undo', 'redo', '|', 'bold', 'italic', '|',
'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor'
]
}
} )
.then( /* ... */ )
.catch( /* ... */ );
</script>

# Installing CKEditor 5 from a ZIP file
If you do not want to build your project using npm and cannot rely on the CDN delivery, you can download ready-to-run files with CKEditor 5 and all its plugins.
- Download the ZIP archive with the latest CKEditor 5 distribution.
- Extract the ZIP archive into a dedicated directory inside your project (for example,
vendor/
). Include the editor version in the directory name to ensure proper cache invalidation whenever you install a new version of CKEditor 5.
Files included in the ZIP archive:
index.html
– A sample with a working editor.ckeditor5/ckeditor5.js
– The ready-to-use editor ESM bundle contains the editor and all plugins. [Recommended build]ckeditor5/ckeditor.js.map
– The source map for the editor ESM bundle.ckeditor5/ckeditor5.umd.js
– The ready-to-use editor UMD bundle contains the editor and all plugins. [Secondary build]ckeditor5/ckeditor5.umd.js.map
– The source map for the editor UMD bundle.ckeditor5/*.css
– The style sheets for the editor. You will useckeditor5.css
in most cases. Read about other files in the Editor and content styles guide.translations/
– The editor UI translations (see the Setting the UI language guide).- The
README.md
andLICENSE.md
files.
The easiest way to see the editor in action is to serve the index.html
file via an HTTP server.
You must run your code on a local server to use import maps. Opening the HTML file directly in your browser will trigger security rules. These rules (CORS policy) ensure loading modules from the same source. Therefore, set up a local server, like nginx
, caddy
, http-server
, to serve your files over HTTP or HTTPS.
All three installation methods – npm, CDN, ZIP – work similarly. So, you can also use the CKEditor 5 Builder with a ZIP archive. Create a custom preset with the Builder and combine it with the editor loaded from ZIP files.
# Installing premium features
# Installing premium features using npm
All premium features are available as a separate package. You can install it the same as the open-source one.
npm install ckeditor5-premium-features
Now, you can import all the modules from both the ckeditor5
and ckeditor5-premium-features
packages. Additionally, you have to import CSS styles separately.
import { ClassicEditor, Essentials, Bold, Italic, Paragraph, Font } from 'ckeditor5';
import { FormatPainter } from 'ckeditor5-premium-features';
import 'ckeditor5/ckeditor5.css';
import 'ckeditor5-premium-features/ckeditor5-premium-features.css';
ClassicEditor
.create( document.querySelector( '#editor' ), {
plugins: [ Essentials, Bold, Italic, Paragraph, Font, FormatPainter ],
toolbar: {
items: [
'undo', 'redo', '|', 'bold', 'italic', '|',
'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor', '|',
'formatPainter'
]
},
licenseKey: '<YOUR_LICENSE_KEY>'
} )
.then( /* ... */ )
.catch( /* ... */ );
Pass the imported plugins inside the configuration to the create()
method and add toolbar items where applicable. Please note, that to use premium features, you need to activate them with a proper license key, mentioned in the final section of this guide.
The first argument in the create()
function is a DOM element for the editor placement, so you need to add it to your HTML page.
<div id="editor">
<p>Hello from CKEditor 5!</p>
</div>
That is all the code you need to see a bare-bone editor running in your web browser.
# Installing premium features from CDN
Just like with open-source features, start by attaching a link to style sheets. They contain all styles for the editor’s UI and content. The styles are in two separate style sheets – for open-source and premium plugins. You can also include your styles if you like. Refer to the content styles guide for more information.
<link rel="stylesheet" href="https://cdn.ckeditor.com/ckeditor5/42.0.2/ckeditor5.css" />
<!-- If you are using premium features: -->
<link rel="stylesheet" href="https://cdn.ckeditor.com/ckeditor5-premium-features/42.0.2/ckeditor5-premium-features.css" />
Then, you need to attach the script with the JavaScript code. To simplify imports, you can use the feature available in browsers – the import map. It allows us to map an easy-to-remember specifier (like ckeditor5
) to the full URL of the file from the CDN. We use this browser feature to share an editor engine code between plugins.
<script type="importmap">
{
"imports": {
"ckeditor5": "https://cdn.ckeditor.com/ckeditor5/42.0.2/ckeditor5.js",

"ckeditor5-premium-features": "https://cdn.ckeditor.com/ckeditor5-premium-features/42.0.2/ckeditor5-premium-features.js",
"ckeditor5-premium-features/": "https://cdn.ckeditor.com/ckeditor5-premium-features/42.0.2/"
}
}
</script>
Once you have added the import map, you can access the editor and its plugins using the ckeditor5
specifier. Import them from the ckeditor5-premium-features
package. Please note that to use premium features, you need to activate them with a proper license key, as mentioned in the final section of this guide.
In the following script tag, import the desired plugins and add them to the plugins
array and add toolbar items where applicable. Note that both script tags (this and previous) have the appropriate type
values.
<script type="module">
import {
ClassicEditor,
Essentials,
Bold,
Italic,
Font,
Paragraph
} from 'ckeditor5';
import { FormatPainter } from 'ckeditor5-premium-features';
ClassicEditor
.create( document.querySelector( '#editor' ), {
plugins: [ Essentials, Bold, Italic, Font, Paragraph, FormatPainter ],
toolbar: {
items: [
'undo', 'redo', '|', 'bold', 'italic', '|',
'fontSize', 'fontFamily', 'fontColor', 'fontBackgroundColor', '|',
'formatPainter'
]
},
licenseKey: '<YOUR_LICENSE_KEY>'
} )
.then( /* ... */ )
.catch( /* ... */ );
</script>
Lastly, add a tag for the editor to attach to.
