draftjs-utils

What is draftjs-utils?

The draftjs-utils package provides utility functions for working with Draft.js, a rich text editor framework for React. These utilities help in manipulating and converting Draft.js content states, blocks, and entities, making it easier to handle common tasks such as extracting text, converting content to HTML, and managing inline styles.

What are draftjs-utils's main functionalities?

Extracting Plain Text

This feature allows you to extract plain text from a Draft.js content state. The utility function `getTextFromContentState` takes a raw content state and returns the plain text.

const { convertToRaw, ContentState } = require('draft-js');
const { getTextFromContentState } = require('draftjs-utils');

const contentState = ContentState.createFromText('Hello, world!');
const rawContentState = convertToRaw(contentState);
const plainText = getTextFromContentState(rawContentState);
console.log(plainText); // Output: 'Hello, world!'

Converting Content to HTML

This feature allows you to convert Draft.js content state to HTML. The utility function `stateToHTML` takes a raw content state and returns the corresponding HTML string.

const { convertToRaw, ContentState } = require('draft-js');
const { stateToHTML } = require('draftjs-utils');

const contentState = ContentState.createFromText('Hello, world!');
const rawContentState = convertToRaw(contentState);
const html = stateToHTML(rawContentState);
console.log(html); // Output: '<p>Hello, world!</p>'

Managing Inline Styles

This feature allows you to manage inline styles in Draft.js. The utility function `getSelectedInlineStyles` returns a set of inline styles applied to the current selection in the editor state.

const { EditorState, RichUtils } = require('draft-js');
const { getSelectedInlineStyles } = require('draftjs-utils');

let editorState = EditorState.createEmpty();
editorState = RichUtils.toggleInlineStyle(editorState, 'BOLD');
const inlineStyles = getSelectedInlineStyles(editorState);
console.log(inlineStyles); // Output: Set { 'BOLD' }

Other packages similar to draftjs-utils

draft-js-export-html

The draft-js-export-html package provides utilities to convert Draft.js content state to HTML. It is similar to the `stateToHTML` function in draftjs-utils but offers more customization options for the conversion process.

draft-js-import-html

The draft-js-import-html package allows you to import HTML content into Draft.js content state. This is useful for initializing the editor with pre-existing HTML content, a feature not directly provided by draftjs-utils.

DraftJS Utils

An collection of useful utility functions for DraftJS.

I have been using DraftJS in few of my projects. DraftJS is very nice library for creating editors. I wrote a couple of utility functions for myself which I can re-use across my projects. They are well tested. I am open-sourcing them so that others can also leverage. Many of the functions described use ImmutableJS.

Installing

npm install draftjs-utils
