Onyx Server

Mailboxing & data service for the Onyx app.

Prerequisites

Node v8+ with npm.

Installation

npm install --global onyx-server

Usage

CLI

onyx-server --port 5000 --http-url http://localhost:8500 --ws-url ws://localhost:8546

All arguments are optional, when not provided the server will use environment variables ONYX_PORT, SWARM_HTTP_URL and SWARM_WS_URL or its defaults (WebSocket on ws://localhost:8546, HTTP on http://localhost:8500 and port 5000).

Additionally you can pass -u or --unsecure to dismiss using TLS, only recommended for when connecting client and server over a local connection

The DEBUG environment variable can be used to activate logs, ex:

DEBUG="onyx*" onyx-server

Connection security

The Onyx client connects to Onyx server using a WebSocket, and so uses TLS certificates to authenticate and encrypt the connection. Use of client certificates is enforced so that only your clients with the correct certificate will be allowed to connect to the server, others are rejected. For mobile clients, where it can be more difficult to handle cert files, the server allows clients accessing the cert endpoint to download a password-encrypted p12 client cert. For convenience, you can use the provided script to generate a set of unique self-signed certificates.

./scripts/gen-certs.sh -p <certificate-password> -i <ip-address-to-certify> -d <domain-to-certify>

Development

To build local version run yarn build. Afterwards you can start the built server with yarn start.

Onyx server depends on having a local swarm node running. You can start it by running the start_swarm_node.sh script. This should allow you to run onyx-server with no special arguments.

in one shell:

./scripts/start_swarm_node.sh <some_swarm_data_directory_here>

in another shell:

yarn start

API

import Conf from 'conf'
import startServer from 'onyx-server'

startServer({
  httpUrl: 'http://localhost:8500',
  wsUrl: 'ws://localhost:8546',
  port: 5000,
  store: new Conf(),
}).then(
  server => {
    console.log('server started')
  },
  err => {
    console.log('failed to start server', err)
  },
)

All parameters are optional, fallback values will be used for the parameters not provided.
