Replaces the default Strapi WYSIWYG editor with a customized build of CKEditor 5 packed with useful plugins.
- Lots of default plugins: for styling text, images, tables and so on.
- Font color picker: choose color for font styling that's not defined in default palette.
- Upload adapter for Strapi: for upload images to your library when you drop an image into the editor.
- Fullscreen mode button.
- Strapi media library button.
- Supports strapi theme swithing.
- Supports responsive images: plugin adds srcset attribute to images based on their
formatsif responsive enable in strapi settings. - Language support: you can set the preferred language for the UI or the content in the configuration, by default it will use the language defined in the user profile if that language is supported. i18 also supported.
Inside your Strapi app, add the package:
With npm:
npm install @_sh/strapi-plugin-ckeditorWith yarn:
yarn add @_sh/strapi-plugin-ckeditorIn config/plugins.js file add:
ckeditor: trueIf you do not yet have this file, then create and add:
module.exports = () => {
return {
ckeditor: true
}
}Then run build:
npm run buildor
yarn build💡
sizesandloadingattributes for image can be set in source mode. If you use default upload provider and you want prefix img url with api path you need to addbaseURLinapi.jsfile(config/api.js)
CKEditor config should be defined in config.editor field in plugins.js file.
plugins.js not plugin.js
plugins.js file should be placed in config folder.
💡fullscreen mode and source mode not supported with balloon and block toolbars.
Learn more about configuration from official documentation.

}If you want to customize editor styles you should define styles in config.plugin.styles field.
Since Strapi resets css styles, it needs some styles to revert back, these styles defined below, also check official documentation.
For theme colors switching this plugin uses css variables depending on html data-theme attribute, e.g. html[data-theme='light'] or html[data-theme='dark'] you cand disable it by setAttribute:false
If you want default ckeditor theme you can set strapiTheme:false
More info about ckeditor theming
Example of customization:
// plugins.js
const styles = require('./styles.js')
module.exports = () => {
return {
ckeditor: {
enabled: true,
config:{
plugin:{
// disable data-theme tag setting //
// setAttribute:false,
// disable strapi theme, will use default ckeditor theme //
// strapiTheme:false,
// styles applied to editor container, e.g:
styles:`
${styles()}
.ck-editor__styled__container{
