Logux Core

Logux is a new way to connect client and server. Instead of sending HTTP requests (e.g., AJAX and GraphQL) it synchronizes log of operations between client, server, and other clients.

• Chat for any questions
• Issues and roadmap
• Projects inside Logux ecosystem

This repository contains Logux core components for JavaScript:

• Log to store node’s actions.
• MemoryStore to store log in the memory.
• BaseNode, ClientNode, and ServerNode to synchronize actions from Log with other node.
• isFirstOlder to compare creation time of different actions.
• WsConnection, Reconnect, and ServerConnection to connect nodes via WebSocket.
• TestLog, TestPair, TestTime, and eachStoreCheck to test Logux application.

Install

npm install @logux/core

Usage

See documentation for Logux API.

import { ClientNode, TestTime, TestLog, TestPair } from '@logux/core'

let time = new TestTime()
let pair = new TestPair()
let node = new ClientNode('client:test', time.nextLog(), pair.left)

import { isFirstOlder } from '@logux/core'

let lastRename
log.type('RENAME', (action, meta) => {
  if (isFirstOlder(lastRename, meta)) {
    changeName(action.name)
    lastRename = meta
  }
})
