A conference on React

An intro to DraftJS, and its immutable data model

Submitted May 2, 2017

This talk shall focus on DraftJS, a rich text editor framework built for React apps; and how it leverages ImmutableJS; for managing the state of an editor in its entirety, with sufficient examples.

The key takeaway insights of the talk include:

  • How DraftJS works under the hood — “What goes into”, and the “How to” of building rich text editors for React applications
  • How one can use ImmutableJS API, to manage DraftJS’s immutable data structures (apart from the DraftJS’ user-facing API)
  • The role of immutability for data models in your own application

The intended audience of the talk are JavaScipt developers who’re acquainted with ReactJS, who are either:

  • interested in building rich text editors, or
  • interested in learning about ImmutableJS, and the benefits of immutability, and immutable data in their apps


  • There are multiple paradigms of text editing on the web; WYSIWYG editors have become a defacto standard for writing long form articles

  • After a brief look at a couple of text editing paradigms; the inconsistent content-editable behaviour across browsers, and how the abstraction provided by DraftJS solves the problem…

  • …the core of the talk would be concentrated on how DraftJS leverages ImmutableJS to maintain the entire state of an editor — the content, the selection state, and a bunch of other things — using an immutable data model

  • Because of the above fact — the entire editor state being nothing but an Immutable data structure — we can conceive any imaginable state of the editor that we might want to, using the ImmutableJS API …and we shall see the same using examples, and code

  • Towards the end the talk shall discuss the benefits of immutability, immutable data structures; which one could consider while building data models for an application
