prosemirror-model

What is prosemirror-model?

The prosemirror-model package is a part of the ProseMirror toolkit, which provides a powerful, flexible, and customizable framework for building rich text editors. The prosemirror-model package specifically deals with the document model, which includes defining schemas, creating and manipulating documents, and working with nodes and marks.

What are prosemirror-model's main functionalities?

Defining a Schema

This feature allows you to define a schema for your document. A schema specifies the types of nodes and marks that can appear in the document, as well as their attributes and how they should be serialized to and from DOM.

const { Schema } = require('prosemirror-model');

const mySchema = new Schema({
  nodes: {
    doc: { content: 'block+' },
    paragraph: { content: 'text*', toDOM: () => ['p', 0] },
    text: { inline: true }
  },
  marks: {
    strong: { toDOM: () => ['strong', 0] }
  }
});

Creating a Document

This feature allows you to create a document using the schema you defined. The document is created from a JSON representation that matches the schema.

const { Node } = require('prosemirror-model');

const doc = Node.fromJSON(mySchema, {
  type: 'doc',
  content: [
    { type: 'paragraph', content: [{ type: 'text', text: 'Hello, world!' }] }
  ]
});

Manipulating Nodes

This feature allows you to manipulate nodes within the document. You can create new nodes, copy existing nodes, and create fragments of nodes.

const { Fragment } = require('prosemirror-model');

const paragraph = mySchema.nodes.paragraph.createAndFill();
const textNode = mySchema.text('New text');
const newParagraph = paragraph.copy(Fragment.from(textNode));

Other packages similar to prosemirror-model

slate

Slate is another framework for building rich text editors. It provides a more flexible and less opinionated approach compared to ProseMirror. While ProseMirror uses a schema-based approach to define the document structure, Slate allows for more dynamic and custom data models.

draft-js

Draft.js is a framework for building rich text editors developed by Facebook. It uses a content state model to represent the document and provides a set of immutable data structures for manipulating the content. Draft.js is more opinionated and less flexible compared to ProseMirror, but it integrates well with React.

quill

Quill is a rich text editor that provides a simple and easy-to-use API. It is less flexible compared to ProseMirror and Slate, but it is very easy to set up and use. Quill is suitable for applications that need a basic rich text editor without much customization.

Bug fixes

When <br> DOM nodes can't be parsed normally, the parser now converts them to newlines. This should improve parsing of some forms of source code HTML.
