    License npm (scoped) node-current (scoped)

    Dependency-free decentralized peer-to-peer network for storage and communication based on the Kademlia distributed hash table.



    npm install @nephys/plexus --save


    npm run test

    This test will create a 50-Node Local Mesh Network and then go through the 4 following steps.

    Step Description
    Item lookup Testing if nodes can find an item on the network
    Node lookup Testing if nodes can find another node on the network
    Broadcasting test Testing if a node can broadcast to the rest of the network
    Non existent item lookup Testing if nodes dont find non existent data on the network*
    * (The lookup should timemout and fail)

    npm run chat

    A demo CLI chat client to test communication between nodes.

    npm run broadcast

    Testing the broadcasting system between 3 node A, B & C where A & B know eachother, B & C know eachother as well and A & C don't know eachother but should be able to communicate regardless.

    //  Expected output:
    [A] b speaking
    [B] a speaking
    [B] c speaking
    [C] a speaking
    [A] c speaking
    [C] b speaking

    Quick Start

    Creating a Plexus Node and joining the Mesh Network.

    const plexus = require("plexus");
    //  Node creation
    let node = new plexus.Node({host: "", port: 8080});    //  By default the host and port are
    //  Join the network
    node.connect({host: "remote_ip", port: remote_port});


    Storing and retrieving data on the Network.

    //  Storing data
    let item = node.store({key: key, value: value, republish: true});   //  If no key is provided it will default to the hash of the value stored
    //  Retrieving data
    let lookup = node.find({key: key});
    //  The item exists on the Network
    lookup.on("found", (result) => {
    //  The item doesn't exist anywhere on the Network
    lookup.on("timeout", () => {
        console.log("FIND request timed out");


    Broadcasting to the whole Network.

    (WIP, subject to forwarding loops under certain network conditions)
    //  Sendind to the Network
    node.broadcast({data: data});
    //  Handling incoming Broadcasts
    node.on("broadcast", (data) => {




    • [X] Implement keep alive (ping contacts to keep the UDP hole open)*
    • [X] Implement Item expiration
    • [X] Implement Item propagation
    • [X] Improve the storage system
    • [X] Clean up code
    • [X] Finish implementing error handling using exceptions
    • [X] Add documentation
    • [x] Make broadcasting faster (master & slave broadcasting nodes?) Complete rework
    * (WIP)
