wspost v0.1.2

wspost is stupid simple HTTP POST -> WebSocket gateway. It's using JWT authorization, but doesn't store any data.

Installation

npm i wspost -g

Generating channel token

You need to define your secret key and generate first channel token. You can set it in ENV or in app parameter.

export SECRET_KEY='< change me >'
wspost --gentoken example

Token can be also easily generated in third party app running on different server and written in other language. The only thing you will need are:

• JWT library
• configuration with the same SECRET_KEY
• payload with claim channel

{
  "channel": "example"
}

Starting a server

There is only one port open for both, HTTP POST and WebSocket communication. By default it listens on port 3000, bout you can change it form command line or ENV variable PORT.

export SECRET_KEY='< change me >'
wspost --listen

Sending a message

Message delivery can be easily tested with cURL.

Try to open localhost:3000/example.html in your browser and wait for a message.

Token which you generated before is used as endpoint URL.

TOKEN=$(wspost --gentoken example)
curl -d something=123 localhost:3000/broadcast/$TOKEN
