Editor.js API

Most actual API described by this interface.

📃 See official API documentation https://editorjs.io/api

Tools have access to the public methods provided by Editor.js API Module. Plugin and Tune Developers can use Editor`s API as they want.

Block API

API for certain Block methods and properties. You can access it through editor.api.block.getBlockByIndex method or get it form block property of Tool constructor argument.

name: string — Block's Tool name (key, specified in tools property of initial configuration)

config: ToolConfig — Tool config passed on Editor initialization

holder: HTMLElement — HTML Element that wraps Tool's HTML content

isEmpty: boolean — true if Block has any editable content

selected: boolean - true if Block is selected with Cross-Block Selection

set stretched(state: boolean) — set Block's stretch state

stretched: boolean — true if Block is stretched

call(methodName: string, param?: object): void — method to call any Tool's instance methods with checks and error handlers under-the-hood. For example, Block lifecycle hooks

save(): Promise<void|SavedData> — returns data saved from current Block's state, including Tool name and saving exec time

validate(data: BlockToolData): Promise<boolean> — calls Tool's validate method if exists

Api object description

Common API interface.

export interface API {
   blocks: IBlocksAPI;
   caret: ICaretAPI;
   sanitizer: ISanitizerAPI;
   toolbar: IToolbarAPI;
   // ...
 }

BlocksAPI

Methods that working with Blocks

render(data) - render passed JSON data

renderFromHTML(data) - parse and render passed HTML string (not for production use)

swap(fromIndex, toIndex) - swaps two Blocks by their positions (deprecated: use 'move' instead)

move(toIndex, fromIndex) - moves block from one index to another position. fromIndex will be the current block's index by default.

delete(blockIndex?: Number) - deletes Block with passed index

getCurrentBlockIndex() - current Block index

getBlockByIndex(index: Number) - returns Block API object by passed index

getBlocksCount() - returns Blocks count

stretchBlock(index: number, status: boolean) - Deprecated. Use Block API interface instead. make Block stretched.

insertNewBlock() - Deprecated insert new Block after working place

insert(type?: string, data?: BlockToolData, config?: ToolConfig, index?: number, needToFocus?: boolean) - insert new Block with passed parameters

SanitizerAPI

clean(taintString, config) - method uses HTMLJanitor to clean taint string.

Editor.js provides basic config without attributes, but you can inherit by passing your own config.

If Tool enables inline-tools, we get it's sanitizing rules and merge with your passed custom rules.

Usage:

let taintString = '<div><p style="font-size: 5em;"><b></b>BlockWithText<a onclick="void(0)"></div>'
let customConfig = {
  b: true,
  p: {
    style: true,
  },
}
this.api.sanitizer.clean(taintString, customConfig);

ToolbarAPI

Methods that working with Toolbar

open() - opens toolbar

close() - closes toolbar, toolbox and blockSettings if they are opened

InlineToolbarAPI

Methods that works with inline toolbar

open() - opens inline toolbar, (opens for the current selection)

close() - closes inline toolbar

ListenerAPI

Methods that allows to work with DOM listener. Useful when you forgot to remove listener. Module collects all listeners and destroys automatically

on(element: HTMLElement, eventType: string, handler: Function, useCapture?: boolean) - add event listener to HTML element

off(element: HTMLElement, eventType: string, handler: Function) - remove event handler from HTML element

CaretAPI

Methods to manage caret position.

Each method accept position and offset parameters. Offset should be used to shift caret by passed amount of characters.

Position can be one of the following values:

Value Description
start Caret will be set at the Block's beginning
end Caret will be set at the Block end
default More or less emulates browser behaviour, in most cases behaves as start

Each method returns boolean value: true if caret is set successfully or false otherwise (e.g. when there is no Block at index);

setToFirstBlock(position?: 'end'|'start'|'default', offset?: number): boolean; — set caret to the first Block

setToLastBlock(position?: 'end'|'start'|'default', offset?: number): boolean; — set caret to the last Block

setToNextBlock(position?: 'end'|'start'|'default', offset?: number): boolean; — set caret to the next Block

setToPreviousBlock(position?: 'end'|'start'|'default', offset?: number): boolean; — set caret to the previous Block

setToBlock(index: number, position?: 'end'|'start'|'default', offset?: number): boolean; — set caret to the Block by passed index

focus(atEnd?: boolean): boolean; — set caret to the Editor. If atEnd is true, set it at the end.

NotifierAPI

If you need to show any messages for success or failure events you can use notifications module.

Call on target Editor:

let editor = new EditorJS({
  onReady: () => {
    editor.notifier.show({
      message: 'Editor is ready!'
    });
  },
});

In Tool's class:

this.api.notifier.show({
  message: 'Cannot upload image. Wrong mime-type.',
  style: 'error',
});

Check out codex-notifier package page on GitHub to find docs, params and examples.

Destroy API

If there are necessity to remove Editor.js instance from the page you can use destroy() method.

It makes following steps:

  1. Clear the holder element by setting it`s innerHTML to empty string

  2. Remove all event listeners related to Editor.js

  3. Delete all properties from instance object and set it`s prototype to null

After executing the destroy method, editor inctance becomes an empty object. This way you will free occupied JS Heap on your page.

Tooltip API

Methods for showing Tooltip helper near your elements. Parameters are the same as in CodeX Tooltips lib.

Show

this.api.tooltip.show(element, content, options);
parameter type description
