Features

Chanify is include these features:

• Customize channel for notifications.
• Deploy your own node server.
• Distributed architecture design.
• Design for privacy protection.
• Support text/image/audio/file message format.

Getting Started

1. Install iOS App(1.0.0 version and above) or macOS App(1.3.0 version and above).
2. Get send token, more detail.
3. Send message.

Installation

Precompiled binary

Download precompiled binary from here.

Docker

$ docker pull wizjin/chanify:latest

From source

$ git clone https://github.com/chanify/chanify.git
$ cd chanify
$ make install

Usage

As Sender Client

Use chanify to send message.

# Text message
$ chanify send --endpoint=http://<address>:<port> --token=<token> --text=<message>

# URL message
$ chanify send --endpoint=http://<address>:<port> --token=<token> --link=<web url>

# Image message
$ chanify send --endpoint=http://<address>:<port> --token=<token> --image=<image file path>

# Audio message
$ chanify send --endpoint=http://<address>:<port> --token=<token> --audio=<audio file path>

# File message
$ chanify send --endpoint=http://<address>:<port> --token=<token> --file=<file path> --text=<file description>

# Action  message
$ chanify send --endpoint=http://<address>:<port> --token=<token> --text=<message> --title=<title> --action="<action name>|<action url>"

# Timeline message
$ chanify send --endpoint=http://<address>:<port> --token=<token> --timeline.code=<code> <item1>=<value1> <item2>=<value2> ...

endpoint default value is https://api.chanify.net, and notification will send by default server. If you have own node server, please set endpoint to your node server url.

As Serverless node

Chanify run in stateless mode, no device token will be stored in node.

All device token will be stored in api.chanify.net.

Message will send to apple apns server by api.chanify.net.

Send message workflow:

Start => node server => api.chanify.net => Apple server => iOS client

# Start chanify
$ chanify serve --host=<ip address> --port=<port> --secret=<secret key> --name=<node name> --endpoint=http://<address>:<port>

# Docker
$ docker run -it wizjin/chanify:latest serve --secret=<secret key> --name=<node name> --endpoint=http://<address>:<port>

As Serverful node

Chanify run in stateful mode, device token will be stored in node.

Message will send to apple apns server direct.

Send message workflow:

Start => node server => Apple server => iOS client

Start server

# Start chanify
$ chanify serve --host=<ip address> --port=<port> --name=<node name> --datapath=~/.chanify --endpoint=http://<address>:<port>

# Docker
$ docker run -it -v /my/data:/root/.chanify wizjin/chanify:latest serve --name=<node name> --endpoint=http://<address>:<port>

Use MySQL as a backend

--dburl=mysql://<user>:<password>@tcp(<ip address>:<port>)/<database name>?charset=utf8mb4&parseTime=true&loc=Local

Chanify will not create database.

Add New Node

• Start node server
• iOS client can scan QRCode(http://<address>:<port>/) to add node.

Send message

Command Line

# Text message
$ curl --form-string "text=hello" "http://<address>:<port>/v1/sender/<token>"

# Text file
$ cat message.txt | curl -H "Content-Type: text/plain" --data-binary @- "http://<address>:<port>/v1/sender/<token>"

Python 3

from urllib import request, parse

data = parse.urlencode({ 'text': 'hello' }).encode()
req = request.Request("http://<address>:<port>/v1/sender/<token>", data=data)
request.urlopen(req)

Ruby

require 'net/http'

uri = URI('http://<address>:<port>/v1/sender/<token>')
res = Net::HTTP.post_form(uri, 'text' => 'hello')
puts res.body

NodeJS

const https = require('https')
const querystring = require('querystring');

const data = querystring.stringify({ text: 'hello' })
const options = {
    hostname: '<address>:<port>',
    port: 80,
    path: '/v1/sender/<token>',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': data.length
        }
    }
    var req = https.request(options, (res) => {
    res.on('data', (d) => {
        process.stdout.write(d);
    });
});  
req.write(data);
req.end();

PHP

$curl = curl_init();

curl_setopt_array($curl, [
    CURLOPT_URL           => 'http://<address>:<port>/v1/sender/<token>',
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POSTFIELDS    => [ 'text' => 'hello' ],
]);

Security

Setting Registrable

Node server can be disabled user registration and become a private server.

chanify serve --registerable=false --whitelist=<user1 id>,<user2 id>

• --registerable=false: used to disable user registration
• whitelist: list users can be add into node server

Token Lifetime

• Token lifetime is about 90 days (default).
• Can configurable token lifetime (1 day ~ 5 years) in channel detail page.

If your token is leaked, add leaked token into the blocklist (iOS client settings).

Note: Please protect your token from leakage. The blockist need trusted node server (1.1.9 version and above).
