  3. yjs

    Shared data types for building collaborative software

    Project mention: Centralized vs. Decentralized: Why Modern Collaborative Tools choose CRDTs | dev.to | 2026-05-28

    In the architecture of my Collaborative-Code-Editor, choosing CRDTs over OT gives me the advantage of not depending on a server for my data conflicts. Using Yjs as my CRDT library, not only fixes the problems OT arises but comes with additional features. A unique identifier keeps track of the characters' identity, and relative addressing that points to the character position in my code editor. The relative position matters because when working with other real-time data types that use indices, you will encounter stale data when inserting. In other words, when two users add character at the same time it will be inserted relative to the left and right parents rather than its place in the document.

    This is basically the principle behind https://socketcluster.io/ scalability; the sharding of channels across available brokers is pseudo-random. It uses a hash function for determinism but the distribution looks essentially random.
