ckeditor5-internallink-plugin

A generic ckeditor plugin to create custom html tags containing an identifier to a referenced item. The referencable items are found by an autocomplete input.

Overview

This plugin has the same features as the default link plugin except that it does not create regular link tags.

The HTML-Tags of this plugin are looking as following:

<internallink internallinkid="123">some text</internallink>

Features

• Create and edit links
• Remove links
• Configurable autocomplete to find the referenceable item
• Show a label (title) instead of the item id
• Open the referenced item in a new tab
• If text is marked the link will be added to it. Otherwise the item title with a link will be added to the text.
• Configurable webservice urls to get the required data
• Test mode to test the plugin without having to implement a webservice

How to use

To be able to use this plugin you need a custom build of ckeditor.

Further instructions can be found here: https://ckeditor.com/docs/ckeditor5/latest/builds/guides/integration/installing-plugins.html

Add the NPM-Package (https://www.npmjs.com/package/@samhammer/ckeditor5-internallink-plugin) by running one of the following commands (depending on your build environment):

yarn add @samhammer/ckeditor5-internallink-plugin
npm i @samhammer/ckeditor5-internallink-plugin

e.g.: https://github.com/SamhammerAG/ssp-ckeditor5-build-inline

Note: We prefer yarn so it is only testet with this build tool.

Configuration

Configuration flags:

Flag name	Description	Example
testmode	If set to true the plugin can be tested without autocompleteurl and titleurl	true or false
autocompleteurl	Configure a json webservice that returns the autocomplete suggestions. The placeholder {searchTerm} is replaced by the search term that is entered to the autocomplete textbox.	http://www.example.com/autocomplete?term={searchTerm}
titleurl	Configure a json webservice that returns the title for a referenced item. This service is called on editing an existing link. The placeholder {internalLinkId} is replaced by the id of the referenced item.	http://www.example.com/gettitle?itemid={internalLinkId}
previewurl	The url that is used to open a preview of the referenced item in a new tab. The placeholder {internalLinkId} is replaced by the id of the referenced item.	http://www.google.de?q={internalLinkId}
axiosInstance	This instance is used to call the autocomplete and the title url. You can use a custom instance e.g if you need interceptors for authentication.	import axios from "axios" and use this axios instance

Example:

InlineEditor
	.create( editorElement, {
		internallink: {
			testmode: false,
			autocompleteurl: '',
			titleurl: '',
			previewurl: '',
			axiosInstance: undefined
		}
	} )
	.then( ... )
	.catch( ... );

Webservice response data format

This plugin requires webservices that are returning json data. We are using axios to do HTTP-GET requests.

Autocomplete response

[
    { label:  'Text1', value:  '1' },
    { label:  'Text2', value:  '2' }
]

Get title response

Returns a string with the title
