Logux Server

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.

• Issues and roadmap
• Projects inside Logux ecosystem

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

const { Server } = require('@logux/server')

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

server.listen()

Logux Server as Framework

const { isFirstOlder } = require('@logux/core')
const { Server } = require('@logux/server')

const server = new Server(
  Server.loadOptions(process, {
    subprotocol: '1.0.0',
    supports: '1.x',
    root: __dirname
  })
)

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()
