Logux Server Cult Of Martians

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.

This repository contains Logux server with:

  • Framework to write own server.
  • Proxy between WebSocket and HTTP server on any other language.

Logux Server as Proxy

import { fileURLToPath } from 'url'

const server = new Server(
  Server.loadOptions(process, {
    controlSecret: 'secret',
    subprotocol: '1.0.0',
    supports: '0.6.2',
    backend: 'http://localhost:3000/logux',
    fileUrl: import.meta.url
  })
)

server.listen()

Logux Server as Framework

import { fileURLToPath } from 'url'
import { isFirstOlder } from '@logux/core'
import { dirname } from 'path'
import { Server } from '@logux/server'

const server = new Server(
  Server.loadOptions(process, {
    subprotocol: '1.0.0',
    supports: '1.x',
    fileUrl: import.meta.url
  })
)

server.auth(async ({ userId, token }) => {
  const user = await findUserByToken(token)
  return !!user && userId === user.id
})

server.channel('user/:id', {
  access (ctx, action, meta) {
    return ctx.params.id === ctx.userId
  },
  async load (ctx, action, meta) {
    const user = await db.loadUser(ctx.params.id)
    return { type: 'USER_NAME', name: user.name }
  }
})

server.type('CHANGE_NAME', {
  access (ctx, action, meta) {
    return action.user === ctx.userId
  },
  resend (ctx, action, meta) {
    return { channel: `user/${ ctx.userId }` }
  },
  async process (ctx, action, meta) {
    if (isFirstOlder(lastNameChange(action.user), meta)) {
      await db.changeUserName({ id: action.user, name: action.name })
    }
  }
})

server.listen()
